How do I make sure that extra student loan payments are applied correctly to my student loans?
The Consumer Financial Protection Bureau (CFPB) created a template for you to communicate with your lender in writing when making a lump sum extra payment.

Here is the template that you can use to make a lump sum extra payment:

“I am writing to provide you with instructions on how to apply payments when I send an amount greater than the minimum amount due. Please apply payments as follows:

After applying the minimum amount due for each loan, any additional amount should be applied to the loan that is accruing the highest interest rate.

If there are multiple loans with the same interest rate, please apply the additional amount to the loan with the lowest outstanding principal balance.

If any additional amount above the minimum amount due ends up paying off an individual loan, please then apply any remaining part of my payment to the loan with the next highest interest rate.

It is possible that I may find an option to refinance my loans to a lower rate with another lender. If this lender or any third party makes payments to my account on my behalf, you should use the instructions outlined above.

Retain these instructions. Please apply these instructions to all future over payments. Please confirm that these payments will be processed as specified or please provide an explanation as to why you are unable to follow these instructions.”

Importantly, remember that lenders pay your interest charges first before they apply your lump sum payment to reduce principal. Also, remember that interest accrues daily. So, it is possible that the amount of principal that is reduced is not equal to the amount of your lump sum payment.
