How it works

Each month interest is added to the balance, your payment plus the extra amount is subtracted, and the loop repeats until the balance reaches zero.

Worked example

A 35,000 loan at 6.5 percent over 10 years has a payment near 397. Adding 150 a month finishes years early and saves about 4,600 in interest.

Good to know

Federal loans may offer income driven repayment or forgiveness. Check studentaid.gov before paying extra.

Frequently asked questions

How do extra payments help?

Extra money goes to principal, so interest builds on a smaller balance and the loan ends sooner.

Which loans should I pay first?

The ones with the highest interest rate, unless you have a better use for the money.
