How to use this student loan calculator

Enter the values requested above and select Calculate. Change any input to compare another scenario. The calculation runs locally in your browser and does not require an account.

Formula and method

For a fixed installment loan, monthly payment uses the standard amortizing-loan formula based on balance, APR and number of monthly payments.

Example

A $30,000 student loan at 6.8% over 10 years can be compared with a shorter term to see the payment-versus-interest tradeoff.

What this calculator is useful for

Estimate the monthly payment, total repayment and total interest on a fixed-rate student loan. The result is intended for quick estimates, checking arithmetic and comparing scenarios. When a result affects a contract, tax filing, medical decision, building-code requirement or other high-stakes situation, verify the result with the appropriate professional or authoritative source.

An amortizing student loan is not a repayment-plan recommendation

Estimate fixed monthly principal-and-interest payments for $35,000 at 6% over ten years, then extend the term to observe the increase in total interest.

What to check: This does not model income-driven repayment, interest subsidy, forgiveness, capitalization, deferment, grace periods, or variable-rate terms. Use your servicer details for an actual repayment decision.
