Student loan repayment calculator
How to use this calculator
You may have a mix of federal and private loans. If you don’t know how much you owe, search for your federal loans in the National Student Loan Data System or your private student loan lender.
This calculator assumes you’ll be paying monthly for 10 years once repayment begins, which is the standard term for federal loans and many private loans.
Click “Add another loan” to include additional loans in each year or select the next year. Select “I’m done” once you are finished adding all of your loans, then “Calculate” to get your results.
Interest will accrue daily on unsubsidized federal and private loans while you’re in college. The total amount accrued will capitalize and be added to your total loan amount when repayment begins. During repayment, interest will continue to accrue and will be included as part of your monthly bill amount.
• Subsidized federal loans accrue interest while you’re in school and during your six-month grace period after leaving school, but the government pays the interest so it won’t affect the total amount you owe at repayment. To qualify for subsidized federal loans you must meet financial need requirements.
• Unsubsidized federal loans and deferred private loans will accrue interest while you’re in school and during the six-month grace period. The amount that accrues will be added to the total amount you owe when repayment begins.
Understanding your results
This total doesn’t reflect the full amount you will pay over time. During repayment, interest will continue to accrue daily and you’ll pay for it as part of your monthly bill.
Use your results to save money
Private lenders may allow you to lower monthly payment temporarily. To permanently lower monthly payments you’ll need to refinance student loans. By doing so, you replace your current loan or loans with a new, private loan at a lower interest rate. To qualify you’ll need a credit score in the high 600s and steady income, or a co-signer who does.
