NerdWallet Student Loan Calculator
Tap a star to rate
NerdWallet's tool covers the full range of federal and private repayment plans, calculating your monthly payment under each option. The calculator also models refinancing scenarios, showing how a new interest rate or loan term would affect both your monthly payment and your total payoff timeline.
This is valuable if you're comparing federal income-driven plans to private refinancing, or if you're unsure which repayment plan matches your current income and goals. The side-by-side comparisons make it clear which path costs most over time versus which keeps your monthly payment low. You'll know whether refinancing actually saves you money or just shortens the loan term.
