Estimates only. Income-driven repayment (IBR, PAYE, SAVE) payments are calculated using 2026 federal poverty guidelines. SAVE plan details are subject to ongoing litigation — verify current rules at studentaid.gov. Forgiven amounts are typically taxable income unless covered by PSLF. Consult your loan servicer for official payment amounts.

Browse Finance TemplatesFederal student loan repayment is not one-size-fits-all. The US Department of Education offers six major repayment plans, each with dramatically different monthly payments, total interest costs, and forgiveness timelines. A $50,000 loan at 6.5% APR costs about $567/month under Standard (10 years, $18,000 total interest) but may cost only $150–$200/month under SAVE — with the remaining balance potentially forgiven after 20 years. This calculator computes all six plans simultaneously so you can identify the plan that fits your cash flow without overpaying in total interest.
Standard (10-year): Uses the standard amortization formula — equal monthly payments over 120 months. This always produces the lowest total interest but the highest monthly payment.
Graduated (10-year): Payments start lower and increase approximately 10% every two years, ending at the same 10-year term. Useful for borrowers expecting income growth early in their career.
Extended (25-year): Same formula as Standard but spread over 300 months — significantly lower monthly payment but nearly 2.5x more total interest.
Income-Driven Plans (IBR, PAYE, SAVE): Monthly payment is capped at a percentage of discretionary income, where discretionary income = AGI minus a multiple of the federal poverty guideline for your family size. IBR and PAYE use 150% of the poverty guideline; SAVE uses 225%. All three cap payments at 10% of discretionary income (IBR can be 15% for pre-2014 borrowers). Any balance remaining after 20–25 years of qualifying payments is forgiven.
Extra payments are applied directly to principal, reducing the balance on which interest accrues each month. The interest savings and time savings are computed precisely against the baseline calculation for the same plan without the extra payment.

Scope note: Calculations use 2026 federal poverty guidelines and current repayment plan rules. SAVE plan is subject to ongoing federal court litigation — its availability and exact terms may change; verify at studentaid.gov before making financial decisions. IDR payment calculations use simplified annual income and do not model annual income recertification changes. PSLF eligibility (which makes forgiveness tax-free after 10 years) requires qualifying employment and is not modeled here. This tool covers federal Direct Loans only — FFEL loans, Perkins Loans, and private student loans have different rules. Always confirm your repayment plan and payment amount with your loan servicer.

About the US Student Loan Repayment Calculator
Standard repayment spreads your loan over a fixed 10-year term with equal monthly payments, giving you the lowest total interest. Income-driven plans (IBR, PAYE, SAVE) cap your monthly payment at a percentage of your discretionary income — often much lower — but extend the term to 20–25 years. Any remaining balance after the term may be forgiven (and is typically taxable).
SAVE (Saving on a Valuable Education) replaced REPAYE in 2023. It uses the most generous formula: payments are 10% of discretionary income, and discretionary income is calculated as AGI minus 225% of the federal poverty guideline (vs 150% under IBR). For borrowers with low income or large families, SAVE often produces the lowest monthly payment. Note: SAVE has faced ongoing litigation in 2025 — verify current status at studentaid.gov.
For loans disbursed in the 2025–26 academic year: undergraduate Direct Subsidized/Unsubsidized Loans are 6.53%, graduate Unsubsidized Loans are 8.08%, and Direct PLUS Loans are 9.08%. Rates are fixed for the life of each loan and set annually by Congress based on the 10-year Treasury note rate.
Any extra payment goes entirely to principal reduction. Because interest accrues daily on your remaining balance, a lower balance means less interest each month. Even an extra $50–$100 per month on a $35,000 loan at 6.5% can save thousands in total interest and shave 1–2 years off the payoff timeline. The calculator shows exact savings when you enter an extra payment amount.
Under current law (as of 2026), student loan forgiveness through income-driven repayment plans is typically treated as taxable income in the year of forgiveness. Public Service Loan Forgiveness (PSLF) forgiveness has always been tax-free. Consult a tax professional for your specific situation.

This calculator models federal student loan repayment plans, which only apply to federal loans. Private student loans do not qualify for IBR, PAYE, or SAVE. However, you can still use the Standard and Extended plan calculations to estimate payments on private loans by entering your private loan balance and interest rate.
