How Student Loan Interest is Calculated and Why it Varies from Month to Month

by · 66 comments

How much debt costs

As you may know I keep track of how much our debt costs each month – which is basically how much monthly interest we pay toward debt.ย  Shortly after I began tracking these numbers I noticed the interest charged on our student loans varies quite a bit from month to month… so I set off to find out why.

How is student loan interest calculated?

Most student loans (including all federally guaranteed loans) use a method of interest accrual known as the Simplified Daily Interest Formula. The difference between simple interest and compound interest (the type of interest that accrues on most major credit cards) is that simple interest is only calculated on the principal balance, not on the previously accrued interest – this is a good thing.ย  ๐Ÿ™‚

Simplified Daily Interest Formula

This is the formula used to calculate all federally guaranteed student loans:

  • Daily interest amount = (Current Principal Balance x Interest Rate) รท 365.25
  • Monthly interest amount = (Daily Interest Amount x number of days in the month)

Here is an example of daily interest calculated out on a student loan of $10,000 at a 6% interest rate:

  • Daily interest amount:ย  (10,000 x .06) / 365.25 = $1.6427
  • Monthly interest amount:ย  $1.64 x 30 (typical month) = $49.28

The above example shows us that a student loan with a balance of $10,000 and an interest rate of 6% would cost $49.28 in interest in a typical 30 day month.

Interest Rate Factor

Some student loan issuing agencies will make mention of something called the Interest Rate Factor.ย  IRF is simply your interest rate divided by 365.25.ย  If IRF is used in their calculation, rest assured that they are calculating interest the same… they just use a different equation to reach the same number.ย  Here is the equation using the Interest Rate Factor:

  • Monthly interest amount = (Number of days since last payment) x (Principal Balance Outstanding) x (Interest Rate Factor)

Let’s plug our example numbers into this equation (our example interest rate factor is .000164271047:)

  • 30 x 10,000 x .000164271047 = $49.28

Notice that we received the same monthly interest amount regardless of whether we used the Interest Rate Factor or not… that is because the math is exactly the same, the equation is just structured differently.

Why does the amount fluctuate each month?

Between my student loan and my wife’s student loan we paid $277 in interest for January 2010.ย  In December of 2009 we paid only $261 in interest and in November of 2009 it was $288.ย  Our principal decreases every month, so what’s up with the large fluctuations and how could we have paid more in November of 2009 than in January of 2010 if the principal is less?ย  Great question.

The answer lies in 2 conditional variables that effect the “number of days since last payment” from month to month:

  1. How many days are in the current month
  2. Did the last day of the calculation period fall on a weekend or holiday

The number of days since the last payment will obviously differ from month to month based on these two variables.

If the month has 28 days the interest calculated will be less than in a month that has 31 days because 3 extra days were figured into that months calculation.ย  Also, if the last day of the month falls on a weekend or holiday, the calculation will not be performed until the next business day thus increasing that months number of days since last payment.

Thus… regardless of the fluctuation in monthly amounts we will never be charged anymore than 365.25 days worth of interest on our student loans in a given year.

I was fortunate enough to get my student loans consolidated at a very low fixed interest rate. However….debt is debt….and interest paid is money I’m not saving!

I recently changed my point of view on my student loan debt when I ran the numbers…I assumed that because it was a low interest rate I could take my time paying these off. However, I now realize a better course of action for me is to eliminate this burden as well.

The fact that the interest is only applied to the principle is the main reason I’ve been paying extra AND making sure the extra is applied first to the principle.

3 sahmCFO

Sallie Mae gives you the daily amount of accruing interest on your loans. Seeing this amount tick up daily shows me how much of my payment is going to just interest alone. It’s frustrating when you make a payment and it takes 3-4 days for them to apply it and in the meantime the interest is keeps adding up…It feels like a race you’ll never win but I’ll just keep plodding away! Great explanation.

4 Deacon Hayes

Thanks for breaking down the difference between “simple interest” and “compound interest.” I actually wondered why that was and now I will be able to explain that to others more clearly. Regardless, my student loan is my last form of debt outside of my house and I am pplanning on paying it off in May 2010, so I won’t have to worry about it much longer ๐Ÿ™‚

5 Matt Jabs

Feels good doesn’t it? ๐Ÿ™‚

6 Deacon

Sorry for the delayed response, just noticed your reply. Yeah it feels great! We paid off all our debt and have been paying extra on our mortgage as well as saving up for retirement!

7 Ryan

As a result of the Health Care and Education Reconciliation Act, beginning July 1, 2010, federal student loans will no longer be made by private lenders under the Federal Family Education Loan (FFELSM) Program. Instead, all new federal student loans will come directly from the U.S. Department of Education under the Direct Loan Program.

8 Danielle

This is not true. Any interest accrued and not paid in full each month is added to the principal balance of your loans, therefore the interest IS compounded more similar to a credit card.

To make the matter worse and more unethical, if you have ever deferred your loans, Sallie Mae does not automatically recalculate your payment plan that was established upon graduation or even clearly inform you that continuing to pay your monthly amounts established by your graduate payment plan will actually INCREASE your principal balance each month. I suspect that many people have found themselves in the same boat as me, where after paying on-time payments for years, I’ve realized that my principal balance has actually grown!

It’s no wonder why the Sallie Mae website and loan structure/payment groups/interest calculations are so cryptic. Helps them steal more money from the pockets of hardworking kids that don’t have the time or wherewithal to decipher their compounding interest scheme.

Sallie Mae is a ruthless, irresponsible organization that takes advantage of the trust that Americans have extended them. Under the cloak of a government-protected, university-sponsored organization that enables Americans to pursue higher learning opportunities lies a more brilliantly cunning business model that could make even the most unscrupulous pyramid scheme or credit card company envious. The greatest trick the Devil ever pulled was convincing the world he didn’t exist.

9 Matt Jabs

Hi Danielle, while I appreciate your opinion toward Sallie Mae (I share your loathing) this article is not about Sallie Mae, and they are but one of several student loan lenders. Secondly, the interest calculation above is correct.

10 damian

Actually I just talked with my student loan vendor, and was told that every month the interest is calculated off the current principle amount NOT the original principle amount so I have to totally agree with Danielle on this one. My original loan was 35,000 but my interest is being calculated by 39,454, because that is the loan plus interest fees. So it is compounded.

11 Daniel

Your loans were capitalized when you re-entered repayment status. Your original loan amount, 35k, probably accrued some interest while you were in school. Unless you would have paid off all of the interest before exiting your grace period, that interest is then capitalized. That’s why your interest is being calculated off of 39,454.

12 Andrew

Good explanation, I really appreciate it. Does a turning of a new year have any effect on it?
My interest payments are as follows:
November 8: $72
December 6: $52
January 7: $99
I have no idea what’s going on, I make the same payments each month and the days between don’t fluctuate THAT much.

13 Matt Jabs

There are a lot of variables at work, but to be sure you need to call your loan provider to inquire.

14 Julie S.


I used your math on my Sallie Mae consolidated loan (9%) & it does accurately depict my last few interest payments, however I took the principal value on 1/27/11 ($17,383.84) and looked at the remaining payments they say I have on that same date (89 payments at $272.96 and 1 payment at $282.03) and created a spreadsheet with your formula. They say my last payment will be on 7/24/18 to pay off the loan, however the spreadsheet says my principal value on 7/24/18 will be -$966.44. How is this possible? It seems as if I will overpay the loan.

Also, I can’t get anyone that understands finance at Sallie Mae to explain to me how I can make principal only payments aside from the regular monthly payment to pay the loan off early. Any advice on that? I erronenously thought all the overpayments I’ve been making were being applied to principal, when in truth they were being applied to future interest. I’m bummed and I’ve overpaid this loan by 2x already and I don’t want to be in the 4x range before it’s over. I believe the Sallie Mae CEO gajillionaire has had enough of my money and I want to do something positive to ensure those crooks don’t get any more of my money than necessary.

Any advice on how to pay this down quickly? I’ve also heard that they take their sweet bippy time applying payments in order to maximize their interest payments.

15 c knight, esq.

Hi Julie — The extra payments you make are not being applied to future interest, but actually reduce the principal AND advance the due date for the next payment (assuming the “extra” amount is at least equal to the amount of a whole month’s payment, because it is not possible to advance the due date for the next payment by a partial month, only a full month). So pre-paying does in fact reduce the principal and does in fact reduce the interest that accrues, while also pushing forward the due date which allows more flexibility if you end up needing to “miss” a payment at some point.

I am pretty good at math and finance (used to work at a hedge fund). It took me a while to figure out this is what is happening. They are not clear about it.

16 Julie S.

Also, I went in my spreadsheet and changed all the dates that fell on weekends or holidays, which were quite a few and now it says my balance on 7/24/18 will be -$961.88.

I can’t think of any other variables I’m missing. Please advise.

17 Matt Jabs

Hi Julie. I know it is terribly frustrating dealing with lenders, especially when trying to repay principal in advance… they never like that. Hang in there, have patience and just keep at it. No one will be terribly helpful to you so you just have to develop knowledge and nerves of steel.

You need to get an amortization schedule from Sallie Mae so that you can see exactly how they are calculating the interest on your loan (not sure if this works, but give this a shot too.) Secondly, continue working with someone over the phone until you are told precisely how extra principal payments need to be made. Tell them you have a lawyer that they will hear from if they do not comply to your 2 requests… they’ll play ball.

Do that and let us know how it goes. God bless.

18 Julie S.


Ironically I did that exact method from that site and applied the Interest Rate Factor and it doesn’t seem to work. I noticed in 2 separate pieces of correspondence with Sallie Mae that might balance was the same for 2 different dates which of course cannot be accurate.

I called three times the other day: once was a promise for an American to call me back, once their autodialer hung up on me, and lastly, I spoke to an Indian who could only advise me that “I must pay interest” regardless of the question I was asking…

I have to admit the phone call was hilarious…it reminded me of that credit card commercial where the guy says “jes, jes” to everything..haha

Nevertheless, I will try and call them again. The stress of making that phone call is horrible! I have 11 nieces and nephews, 5 of which are in their first year of high school and I plan on teaching a finance class to all of them…especially the part about college loans.

Did you read the article about how Sallie Mae recommends you paying the interest on your loans while in college so you can save more money? Er…you save more money by borrowing less…especially if you can afford to make interest payments…instead borrow LESS money. They really prey on the financially illiterate….fortunately I’m in recovery. ๐Ÿ™‚

Thanks for all your advice!

19 Matt Jabs

Yeah, lenders are incredibly aggressive in our modern culture, but as you and I are both fully aware… we made our bed. So, the next best thing to do is what we’re both doing – digging ourselves out of our mess and work to teach others to avoid the same mistakes.

I lead Dave Ramsey’s FPU out of my church, it is a great curriculum. Depending on how old your nieces/nephews are I suggest you check into Dave’s kids literature or if they’re old enough just run them through FPU. If someone would have done that for either of us we would most likely be in a much better way… so let’s work to start others off on the right foot by having what we did not. ๐Ÿ™‚ God bless.

20 Julie S.

Hi Matt,

Well I spoke with Sallie Mae on the phone this morning for over an hour since I was able to get my hands on a special phone number they have for “consumer advocacy.”

1. She did not have a legible copy of my promissary note & suggested I go back to the original lender to get it until she realized the original lender, USAA Group Loan Services, merged with Sallie Mae. I may never see a legible copy of the original promissary note, but I did put in a request for them to hunt it down via microfiche.

2. She told me that although overpaying the loan does forward the due date out, any amount paid over the interest and fees (i.e., late fees, etc.,) are applied to principal. She said I do not have to send in a separate payment for that to happen. I concluded that I should continue overpaying and ignore the due date since the overpayment will continue to get the due date pushed out, and if I want the overpayment to actually be applied to principal, I need to keep paying every month, regardless of the due date.

3. Apparently they rarely do a recalculation on the loan. They only do it when it would seem that at your current payment you won’t finish paying the loan off by the agreed upon final due date in the original loan. Federal law requires them to recalculate your minimum payment in order for the borrower to make that date, regardless if you’ve been in forebearance. Conversely, they do NOT do a recalculation in the event that you’ve overpaid and will pay the loan off early.

It’s tricky because their correspondence will have a current date with remaining principal balance and on the same correspondence, they will tell you the number of payments, the amounts, and the pay off date. However, that portion is NOT updated so although it may have a current date on the correspondence, that information on the correspondence is erroneous.

I would think they would update all of the information correctly on dated correspondence, but they do not. Additionally, she kept telling me the formula they use assumes 30 days since the last payment for pay off estimates. With all those thousands of employees I would think they would write their formulas more accurately to take into account payment due dates that fall on weekends and/or holidays.

She ran her calculator and since I’ve been paying over the minimum due, my actual minimum payment IF they were to do a recalculation is less (in theory) and that is why their calculation says I’ll pay it off in 7/2018. In truth I will pay it off much sooner.

Thanks for the formula. I feel like I’m in control now since I have a spreadsheet and I can actually see how altering payment amounts and due dates affect the pay off date.

Lastly, I did ask her for an amortization schedule, and she told me the federal government does not allow them to provide that. Ha! That one is hilarious!

At least though I got to speak to a polite, if not overly rambunctious, semi-informed American.

If anyone wants that coveted phone number, send me an email & I’ll provide it!

21 Matt Jabs

Awesome Julie, I am glad that you have regained a sense of understanding and control over the loan repayment, and thank you for updating us here. Your information will help other people. I think you should reply to this comment and permanently publish the phone number on this page, that would help many I’m sure.

Hi guys,
I believe Sallie Mae is misallocating principal and interest payments.
by increasing the due date, sallie mae is allocating your payments into interest more than principal?
It is fraudulent accounting. b/c they will automatically charge you interest in today’s payment for interest to be accrued in the future when they increase the next payment due date.

24 Matt Jabs

Hi Rattan,
I don’t doubt it, but do you have any documented proof of this?

25 Julie S.

Sallie Mae is not misallocating principal and interest. They charge interest exactly as the formula Matt provided states. If you create a spreadsheet, use the formula exactly like it is without rounding and your numbers will be correct.

It may seem that way, however it is not. They charge late fees, then interest (from the date of last payment), and the remaining amount goes to principal.

They are guilty of aggressively pushing foreberance and deferment on you, since they make a boatload of money, however, unfortunately, they do not have to follow the same rules as credit card companies do by telling you how much more you’ll be paying.

Even consolidating can be very costly, since they typically spread the payments over 20 years in lieu of the original 10 years. Also, when they advise you to make interest payments while in school to avoid big loans, that is another misnomer, since you’re better off if you have excess money available to make interest payments, you should just borrow less. In the long run, you will save tons by borrowing less.

Student loans are not like car loans. If you are late ever or miss a payment, that interest is capitalized and then you must make interest only payments to catch up. Once I missed 3 payments and it took me 13 months to catch back up, since all of my payments were going to capitalized interest.

It just becomes a dark hole, so no what matter what, keep making the payments on time. Then Sallie Mae can make their gobs of money off of some other poor sucker.

26 ohricky

Does anyone know if it’s possible to apply a payment towards a particular loan? In my Sallie Mae account, have a single billing group encompassing 7 loans of varying amounts; I’m wondering if there’s any benefit to knocking any of those specific loans out.

27 Matt Jabs

Are they all the same interest rate? If so, the only benefit to knocking one out before the others is to see less loans under the group. If that motivates you then you can go for it. To accomplish this you’ll need to continue paying your minimum payments plus extra principal payments with specific instructions to apply toward that individual loan (the smallest first.)

28 Heather

Julie S.

Is there anyway you could e-mail me the spreadsheet you made, except blank? I read all the comments, but I’m having a hard time visualizing how to setup a spreadsheet using this information. If there is anyway you could send me a blank spreadsheet setup the way you use it, I would greatly appreciate it. Could you title the e-mail loan spreadsheet?

Thank you,

29 Matt Jabs

Hi Heather, I never created a spreadsheet for this calculation, I simply used a calculator and plugged in the numbers. Commentator Julie created a spreadsheet but I never received a copy of it. You should be able to plug in your numbers and find your answer.

30 Bill

Is there any advantage to make multiple payments per month versus only one payment? For example, if my monthly payment is $1,000, should I make a payment of $250 every week instead of one monthly payment of $1,000?

31 Matt Jabs

Although it seems like there may be, after running the numbers there is no advantage. I also spoke extensively with my loan provider to ask the question and they confirmed my hunch.

32 maybelfort

Seems that the way interest is calculated is plain wrong and adverse to students. Wondering if there is any consideration to change the way it is calculated. Seems to me if calculated the same as a mortgage, it would be easier for students.

33 Matt Jabs

That I cannot answer. I would say call your loan provider and perhaps your representatives.

34 Rich

remember the calculation is based on the due date. So if you have a due date of October 31 and you pay on October15 the next bill is calculated for interest of 16 days in october and the 30 days in November. Making the bill higher even though they do put the early payments toward your principal the bill is still higher because the bank has to assume you will not pay until the Nov 30 due date. This is a hard lesson

35 Matt Jabs

Yep, and remember that no matter when you pay you will always pay the same interest amount because there is 365 days of interest charged regardless of when you send payments. (Late payments not included of course because then fees will be tacked on.)

36 Mike R

Thanks to Matt for this subject and all those who added to it. By studying comments here and fully reviewing the Sallie Mae website, I got smart enough to call Sallie Mae and persist when answers were incomplete. There definitely are varying levels of customer service. My 7th call connected with a senior Advocate who had greater access to loan history which solved the dilemma. The senior Advocate clearly had more experience and authority and sent me a hard copy of the full history which was incomplete on the website account. One’s chances of success are greatly improved in knowing what questions to ask and persist until you have clarity. Still, it took 6 weeks from my first call to full resolution.

37 Matt Jabs

Way to persist Mike!

38 Sara

I stumbled across your website trying to figure out interest calculations and have a couple questions. I have a Wells Fargo student loan from 2005 (original balance $13,775) and upon review today, my balance has decreased to $11,639. So I started to wonder how in the heck my balance only went down a little over $2,000 in 6 years! I went through my promissory note and while I’m not 100% certain I understand their legal jargon (why can’t they put notes in layman’s terms?) interest isn’t capitalized after the deferment period, just added to the total interest paid. The term length is 180 months regardless of how long I’m in deferment.

I came across your calculation tool and used it to figure how much of my principal is being paid each month. I gathered up all my statements and went from month to month calculating. So please let me know if I’m doing it right… I took the amount of days between my last payment received and current payment received, multiplied by the principal of the loan, multiplied by the interest rate factor. Sometimes I would pay the amounts due within 28 days, sometimes it was 38 days. Should I use a 30 day interest period across the board?

Anyway, my numbers are different from what my statements are saying. It appears that more of my payments should be applied to principal but are going to interest. It is small amounts, maybe $2 here and $5 there, but that can add up over the lifetime of the loan! What I’m worried about is that if this is happening then that means I’m being charged more interest than I should be since my principal isn’t decreasing properly and, my 180th payment could me some exponentially large amount due to these calculations.

Am I looking at this right? Is there something that needs to be done?

Some more information:
I have not had any late fees in the past year.
I am in full repayment.
My interest rate is variable but has been at a steady 9% for the past 18 months.

What am I missing? Thanks.

39 Matt Jabs

Hi Sara, the only way to know for sure is to call your loan servicer and work it out with them. It is possible they made a mistake so if you go over the details with their support reps, you will be able to work it out and get the final answer.

40 Mady


I recently graduated last year and am in the process of paying off my student loans. I am utterly confused as to why the balance keeps going up instead of going down when I pay my payments on time or before time. I called up Sallie Mae and they say this is due to interest. If anyone can explain the financing procedures that would be much appreciated, thank you.

41 Dave

This answer to this one is, your payments are probably not enough to cover all the interest for that month. You pay on the interest every month before you pay the principle. If what your paying does not cover all the interest, then nothing is going to the principle and the interest continues to add up. You should call your loan servicer and find out how much it will take a month to pay on the interest in order to start paying on the principle. You are probably on a fixed budget repay that you selected when you started your payback.

42 Matt Jabs

Yeah, call them and get to the bottom of it. Loan servicers love to put borrowers in this situation because it’s a never ending source of income for them. They won’t fix it so you have to be responsible and do it ASAP.

43 Rachel Miller

How do you fix it? Just adjust your payment amount higher?

44 Dave

2 questions: (first off, I am glad I am not with Sallie Mae…lol)

1) I have 14 student loans in default equaling approx $44,000 with all the collection fees added. I am unemployed for a year now. Should I consolidate my loans to clean up my credit or should I just pay the 2 collection companies fees for the 9 rehabilitation months to get my loans out of default before being able to pay on my loans again?
2) Paying down the principle… In order to pay extra towards just the principle of the loan, I would need to make an additional monthly payment each month? and it needs to equal the amount of the current payment so that it will all go to just the principle?

45 Matt Jabs

Hard to say Dave, without knowing the whole picture. From what you wrote, if I were you I would probably consolidate and start paying again on the new, single loan balance. Always pay extra if you can, it speeds repayment and saves tons of interest money in the long run.

46 Dave

thanks Matt, 4.4% will be the average interest rate on a consolidation which is hard to beat

47 Matt Jabs

That’s a great rate.

48 Zaven Altounian

I have several student loans at 6.8% interest. The loans are still in deferment for another 1.5 years. If the loan is calculated based on simple daily interest and not compounded, wouldn’t it make more sense to focus your money of paying of a single loan instead of paying the accrued interest for several loans at a time? I have 10 loans to payoff. Fortunately half are subsidized while in school. Some of these loans have as much as $2-3K in accrued interest.

49 Daniel


Mathematically, since your student loans are all the same interest rate, it does not matter if you focus money on one loan versus another. A simple cash flow diagram illustrates this concept. However, I do recommend focusing any extra payments towards a single loan. This allows for a mental victory as you get to knock out one of your several student loan. I also recommend paying off the student loan that has the accrued interest first. When you repay your loan, any payments made to that loan first go towards capitalized interest, then accrued interest, then the principal. You get to deduct that student loan interest on your 1040. This way you are reducing your taxable income by up to 2,500 by putting money towards loans that have accrued interest.

50 Rachael W

Hey Matt,
I just stumbled onto your blog. Great place!! I have a few questions about loans.
First off I am a huge Dave Ramsey fan and my husband and I are currently following the debt snowball. All consumer debt will be gone in 2 months. Now we have student loans and house left. I will just say that since we work in medicine our loans are the equivalent of a huge house we have never seen.

So with that said, our friend is a CPA and suggested paying the house 1st and not student loans. She stated it is better to own an asset then pay off the loans and have nothing to show for other then no more loans. I see her point but the amount we owe in loans makes me feel like I will never see the light at the end of the tunnel.

So my questions. 1. Focus making a little extra on the house and student loans next? 2. Only focus on student loans and nothing extra for the house? And if I focus on loans wouldn’t it be wiser to hit the largest with the most interest (I know the gazelle intense idea) but I think it will save us the most in the long run. What I mean is attack a $30k loan at 8.5% as opposed to $7k loan at 3.25%.

Please give me your thoughts because I am having a hard time deciding what to tackle in my next step. Oh and lastly my husband wants to do 60% house, 40% loans. But I am the nerdy one with the calculator punching the numbers and scratching my head saying “I’m not so sure?”

Thanks for any advice and your site ๐Ÿ™‚


51 Matt Jabs

How does your mortgage rate compare to your student loan rates? Whatever you do, be sure you both agree on the solution. What would I do? I would pay the highest rate loan first, because this will save you the most in the long run. That said, paying extra on both is also a good idea – if your husband wants to do 60/40 then do that – any debt repayment is good, just be sure to hit the high interest loan way before you touch that 3.25% (pay that last). Hope this helps Rachael. Blessings.

52 zaria

Please help with calculation
I have a consolidated loan with sallie mae
Original amt$8032.26
Outstanding Principal$8906.11
Interest Rate 7.125 but they said that If I make auto payment they can reduce the interest rate by 0.25 which make the rate to 6.87.
The minimum payment required is $52 but I am planning on paying $200 a month. The rep on the phone can not explain to me exactly will be paid off by the time the balance is zero. I don’t know what calculation she used; she said that it will be 52 months and any payment over the minimum will go to the principal balance. Does it sound good or is there another way that I can bargain this loan; or better yet do you think I should pay it off all at once( I want to better my credit score and paying it off all at once is not good; I heard) .


53 Matt Jabs

Zaria, if you can pay it off, go ahead and do so – for sure (your rate isn’t great and less debt is always good). Otherwise, if you insist on maintaining the debt, pay the $200/month, all extra WILL go toward the principal. Blessings.

54 zaria


Thanks for your reply earlier but I just spoke with one of the rep for Sallie Mae and she said that if I enroll to auto pay and make a payment of $200 $58 will go to the principal and $142 will satisfy the interest rate; which I decided not to do that as it is a bad deal. How do you think I should approach these ppl from messing up my credit and…it seems now I can not pay off the loan as well…I appreciate your help

thank you

55 Matt Jabs

It’s tough to advise you when I have no intimate knowledge of your situation so I’ll recommend you speak with your financial advisor, but I can tell you that my student loan provider applies all my overpayment to my principal amount. Hope this helps, blessings.

56 zaria


That is what they say last week any over payment to go to the principal last week now when I am ready to enroll in to the auto pay they changed their mind and said that the over payment will be applied to the interest…I asked them to write official letter stating what they told me today…again thank you for your insight and quick reply.

57 Matt Jabs

That’s the best idea, because there should be no room for mind changing, they have to stick with their official policies, so yeah, get it in writing. Blessings.

I have searched a long time to find a way to lower my student loan interest rate. So far I still haven’t had any success. Thus far, my loan are in excess of $100K with a fixed rated of 6.8% across all loans. Some loans are SallieMae and some are through MyFedLoan.

I don’t have a problem making the payments. I just want to lower the rate. Are there any programs to lower the interest rates?

Thank you,

With the exception of consolidation the only way I know of is to enter yourself into their auto-pay programs, and they usually lower it by 0.25%. You can only consolidate student loans once, so if you have never done so, try to go that route. Blessings.

Hey all,

After reading a few posts I would like to mention a few easy methods on how to ride yourself of a few high interest rate student loans if you have acceptable credit. My current situation allowed me to pay off two loans that had an interest rate of 9%.

The first method was to apply and be accepted for a credit card that has a whole year with a 0% interest rate (I was eligible through Key). Of course, use caution because if you do not pay off the card by the end of the year you could actually pay more.

The second method was to apply and be accepted for an auto loan, on my current paid off car, for which I was eligible for 6.75%. Again, the idea here is to shorten the time period in which you are repaying as well as getting a better rate during this time period. Luckily they don’t actually check to see if you have full coverage insurance, but if they ask you will have to tell them that you do.

Anyway, hopefully this will give some of you a few ideas on getting rid of the high interest rate student loans.

If you have been noticing your student loans increasing what seems randomly, within 2 days…6 days… etc. For example with me, I have a loan that should accumulate a maximum of $25 interest (even though Sallie Mae will take about $27 in interest from my payment, why also addressed in my other point) when you notice in 7 days like I did that you already earned from January 31st to February 7th a whopping $17 in interest, basically Sallie Mae is PRO RATING interest.
It took me a little while to realize what was going on, the numbers just weren’t adding up, then when I paid off a balance in full before the due date and noticed upon logging in that there was interest accumulated on what should be a zero balance that’s when it hit me.

So what Sallie Mae seems to be doing is assuming when you send a payment, it won’t post for another 3-4 days anyway, therefore they take it upon themselves to pro rate the interest you would accumulate on a daily basis. The problem is they will prorate interest as in my case that is more than half what the end of month interest rate should be (in my case about $12) so because they have added $17 within the first 7 days of the billing cycle, if you paid on the 8th day, by the time it posts (which would well clear the time for another 7 days) you have prepaid an extra week of interest (about $6 for me), so you are actually paying the interest you have not yet accumulated.

By the way, there is no way this can be legal, by pro-rating the interest, it means you are losing out on money that could be allocated to your principle, which in turns means you pay more interest on the principal since they force you to pay on interest you have not yet accumulated.

I graduated in 1992 from college and consolidated my remaining student loans on Aug 1, 2003, with Sallie Mae in the amount of 38,683.50 at 8% interest. Since that date, I have made 191 payments totaling $59,338.63. On the SM web site, as of Jan 28, 2013, it reflects that $26,775.58 was applied to my outstanding principal and $32,501.12 was applied to the interest. A total of $61.93 was applied to late fees (Sep 03). This all sounds pretty good and I’m thinking there is a light at the end of the tunnel, when on Jan 28, 2013, I receive on-line correspondence that states my outstanding principal is $30,535.25. Once I picked myself up off the floor, my blood ran cold when I realized that out of the nearly $60,000 I had paid, my principal was reduced by just a little over $8 thousand dollars.
I have been in contact with SM trying to get answers, but after 2 attempts I am still in the dark. I am wondering where the other $18,626.33 they say was applied to the principal has gone. If I consolidated one amount and have never missed a payment, how can this be possible and where did the other money go??
I am not giving up and will next contact them again and again until I understand what is going on. Based what I’ve told you, can you provide any input that would help me to better converse with them or help me to understand where the missing money has gone?
I have never missed a payment since the consolidation and the late fees were for Sep 03, the month immediately following the consolidation.
Thanks for listening and for any input you can provide to me.

I’m about to enter repayment period and, based on all the loan formulas I’ve seen, isn’t it a really good idea to make weekly payments? They calculate interest daily, therefore less principle interest balance will exist each day if you make a weekly payment. Less principle balance means less money for them to calculate interest on. Ideally, shouldn’t we be making payments daily? Every minute if possible?

Unfortunately, you save very little doing weekly payments compared to the inconvenience factor of making weekly payments for many many years. Just focus on making large monthly sums and your schedule will thank you for it.

Really? Five percent savings per month over the loan period if my calculations are right, is a substantial amount of money saved…I used 6.9% APR.
