Use our student loan calculator to estimate your monthly payments on a single federal student loan or private student loan. You can also calculate the total payment on multiple student loans at different interest rates as well as the total interest you'll pay.
You’ll get the most accurate results if you enter your loan amounts separately with their precise interest rates, but you can also estimate or use the sample loan amounts and interest rate provided.
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 contact 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.
Loan amount
Enter the total amount you borrowed for each loan. You can enter up to three loans for each year you’re in school, up to four years. It’s possible to include 12 loans total.
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 rate (APR)
Enter the interest rate for each loan amount. Your interest rates will vary depending on whether your loans are federal or private, the year you borrowed and, in some cases, your credit score. Check with your federal loan servicer or your private lender to find out your interest rate.
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.
Is this a subsidized federal loan?
Select “Yes” if you have a subsidized federal loan or “No” if you have an unsubsidized federal loan or a private loan.
• 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
Your monthly bill amount
This is the minimum amount you must pay each month during repayment to stay current.
Amount you borrowed
This is the sum of all the loan amounts you entered.
Accrued interest while in school
This is the total interest that accrued daily on each of the loan amounts you entered during school and the six-month grace period.
Total to repay
The total to repay is the amount you borrowed plus the accrued interest while you were in school that capitalizes. This is how much your total debt will be when you begin repayment, typically six months after leaving school.
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
Pay your interest during school
If you have unsubsidized or private student loans, you can lower your total to repay by making monthly interest payments while you’re going to school. Or, you may opt to make a lump sum payment of the total interest that accrues before repayment begins. Either method will prevent the interest that accrues from being capitalized. The result: a lower monthly bill amount.
Pay more than the minimum
You can submit more than your monthly minimum to pay off your loan faster. The quicker you finish paying your loans, the more you’ll save in interest. Learn how to pay off your student loans fast.
Lower your monthly payments
If you’re having trouble making payments on your federal loans, you can extend the term to 20 or 25 years with an income-driven repayment plan. Income-driven plans lower your monthly loan payments, but increase the total interest you’ll pay throughout the life of your loan.
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.

Fixed APR
3.49-15.49%
Lowest rates shown include the auto debit. Advertised APRs for undergraduate students assume a $10,000 loan to a student who attends school for 4 years and has no prior Sallie Mae-serviced loans. Interest rates for variable rate loans may increase or decrease over the life of the loan based on changes to the 30-day Average Secured Overnight Financing Rate (SOFR) rounded up to the nearest one-eighth of one percent. Advertised variable rates are the starting range of rates and may vary outside of that range over the life of the loan. Interest is charged starting when funds are sent to the school. With the Fixed and Deferred Repayment Options, the interest rate is higher than with the Interest Repayment Option and Unpaid Interest is added to the loan’s Current Principal at the end of the grace/separation period. To receive a 0.25 percentage point interest rate discount, the borrower or cosigner must enroll in auto debit through Sallie Mae. The discount applies only during active repayment for as long as the Current Amount Due or Designated Amount is successfully withdrawn from the authorized bank account each month. It may be suspended during forbearance or deferment. Advertised APRs are valid as of 11/25/2024. Loan amounts: For applications submitted directly to Sallie Mae, loan amount cannot exceed the cost of attendance less financial aid received, as certified by the school. Applications submitted to Sallie Mae through a partner website will be subject to a lower maximum loan request amount. Miscellaneous personal expenses (such as a laptop) may be included in the cost of attendance for students enrolled at least half-time. Examples of typical costs for a $10,000 Smart Option Student Loan with the most common fixed rate, fixed repayment option, 6-month separation period, and two disbursements: For a borrower with no prior loans and a 4-year in-school period, it works out to a 10.28% fixed APR, 51 payments of $25.00, 119 payments of $182.67 and one payment of $121.71, for a Total Loan Cost of $23,134.44. For a borrower with $20,000 in prior loans and a 2-year in-school period, it works out to a 10.78% fixed APR, 27 payments of $25.00, 179 payments of $132.53 and one payment of $40.35 for a total loan cost of $24,438.22. Loans that are subject to a $50 minimum principal and interest payment amount may receive a loan term that is less than 10 years. A variable APR may increase over the life of the loan. A fixed APR will not.
