<prompt> Human: Background: I graduated from college 3 years ago and Ive been paying off my loans as fast as possible. Ive never missed a payment and Ive been putting a lot of extra money into the loans every bonus last year plus more. My loans were services by Direct loans until earlier this year when Mohela bought them out. The problem:Yesterday I looked at my bank statement and found that Mohela, the company servicing my student loans, changed me an extra 132.22 dollars this month. I went onto their website and found my loan balance increased by over 9000.The two loans in question are the following:1 2625 distributed on 930042 3500 distributed on 83105These are subsidized loans and I graduated from this college in December of 2008 government paid the interest until then. I also deferred them for a year for grad school.In April of 2013, the loans had the following balances:1 1944.202 2591.14Now on the July statement, the loan balances are:1 6025.772 8031.86The interest rates on these two loans were variable interest rates, but the average was about 2.3I called the company and they are taking their time figuring this out while Im left here stressing over it. Theyve mentioned keywords like capitalized interest.I dont fully understand how capitalized interest works. In my mind, there is an interest rate and that is the amount of money the bank makes off of your loan each year. I received no notification of outstanding interest balances. Heck they didnt even send me a notice when they increased my loan balance by over 9000... My old direct loans statement show 1784.47 in the capitalized interest field, but that was added into the principal balance. That number is the total for about 9 different student loans, not just these two.Assuming an average of 2.3 interest for 8.5 years, thats a total interest of 1197.44 dollars over that period of time. That isnt taking into account any payments being made so it should really be lower than this. 26253500 0.023 interest per year 8.5 years 1200Can someone help explain this to me? Am I missing something? Is there any kind of sure shot argument I can make to Mohela to get them to drop these charges? How is it even possible that these two loans are now 230 higher than their original balances?Edit: As much as Id love to blame Mohela, Im starting to think the root of the problem isnt with them. If NSLDS.ed.gov shows the same numbers Mohela has in their systems, and Mohela pulls their data from the same source as NSLDS, it doesnt sound logical for Mohela to be the culprit. That is, unless Mohela can publish data to NSLDS.Edit2: Someone here said Mohela can most likely publish data there... So much for that theory :Edit3: Mohela got back to me and they think its an error. They just dont have proof for their theory yet.Edit4: Mohela believes the found and fixed the error, but it wont post on their systems for a few days and wont post on the website for about a week. They dont know if the number will change or disappear... Apparently some software program thought 1 months worth in interest while my loans were deferred in grad school was over 9000 dollars.. If you think about it, the interest rate was roughly 2.3 and the loans increased by about 230. Coincidence? I think not!  <response>: Make them give you a month-by-month balance accounting i.e. for each month, balances started at X, Y interest added, Z payment applied. Decent lenders will be happy to do this, though it sounds like you may have ended up with one that isnt :
