Understanding Student Loan Repayment
This calculator helps you plan your student loan repayment strategy. Enter your loan balance, interest rate, and repayment term to see your required monthly payment and total interest cost. Add an extra payment amount to see exactly how much faster you can pay off the loan and how much interest you'll save.
Federal vs. Private Loans
Federal student loans offer income-driven repayment plans and forgiveness programs. Private loans have none of these protections but may offer lower rates for borrowers with excellent credit. Manage federal and private loans separately when building your repayment strategy.
When to Refinance
Refinancing makes sense if you can lower your rate by at least 0.5–1% and have stable income. Never refinance federal loans into private if you might need income-driven repayment or are pursuing PSLF. For private loans, refinancing with a better credit profile than when you borrowed can save thousands.
