How Student Loan Interest Works

Get tips for reducing your student loan interest

When you take out a student loan, you agree to pay back the loan plus interest. The interest is the fee you pay the lender—such as VSAC or the federal government—in exchange for borrowing the lender’s money.

How Student Loan Interest Accrues 

At the start of the loan, you agree to a certain “interest rate.” This is the percentage of your total loan amount (called your “principal”) that you will be charged for each year that you hold the loan. Interest accrues (or builds up) on a daily basis. So you accrue 1 days’ worth of interest for each day you owe a balance to the lender. 


How Payments Are Applied 

Each month, your loan payment is prorated (or distributed) based on the amount due for each loan group. Your payment is first used to pay any interest that has built up since your last payment. Then, the rest is used to pay down your principal. If your payment is late, the funds will be applied to the most past due loan group(s) first. 

To estimate how much loan interest has built up since your last payment, use this calculation:

How to Pay Less Student Loan Interest  

One of the best ways to reduce student loan interest is to pay extra—even if it’s just a little bit—with each payment.

Here’s why:

Your interest is calculated based, in part, on your principal amount. So the lower your principal, the less interest you’ll have to pay each month. Plus, when your principal balance reaches $0, you have successfully paid your loan in full—and you no longer need to pay principal or interest.

So the goal is to pay down the principal as quickly as possible. 

If you send more than the amount due each month, the extra funds are first applied to any outstanding interest and the remaining amount goes directly toward paying down your principal. This helps you to pay off your loan more quickly—and reduce your total estimated interest charges.

How to Prepay Your VSAC Loan 

Did you know that many students start paying their student loans while they’re still in college—even when it isn’t required? It’s true—and it can be a very good idea. Starting repayment early can help you graduate with less debt and put you in a better position to repay your loan.

With VSAC loans, it’s easy to start repayment early or to pay off your loan early (called “prepaying”). You may prepay all or a portion of your VSAC loan(s) at any time, without penalty.

When you make your monthly payment, include any special instructions you may have for the payment on your monthly payment coupon.

To pay your loan(s) in full, you must pay the principal balance plus any outstanding interest. Contact us for your payoff amount.
