What is a Loan Forgiveness?
A Student Loan Forgiveness Calculator estimates your monthly income-driven repayment (IDR) payment and projects how much of your federal student loan balance would be forgiven at the end of your repayment term. By entering your loan balance, annual income, family size, repayment plan, interest rate, and expected income growth, you can model your entire repayment timeline — from starting payment to total dollars paid to estimated forgiveness — for any of the five major federal repayment programs.
Federal student loan repayment in the US is unlike a standard mortgage or auto loan. Rather than a fixed payment based on the balance owed, income-driven repayment plans set your monthly obligation as a percentage of your discretionary income — the difference between your annual income and a multiple of the Federal Poverty Line for your family size. If that calculated amount is less than full interest, your balance may grow over time. At the end of the repayment term (10 to 25 years depending on the plan), whatever balance remains is discharged — wiped clean.
The five programs this calculator models are SAVE, PAYE, IBR, ICR, and PSLF. SAVE (Saving on a Valuable Education) is the newest and most generous IDR plan for most borrowers: it uses a higher income threshold (225% of poverty line instead of 150%) and provides an interest subsidy that prevents your balance from ever growing above what you originally owed. PSLF is distinct from the IDR plans — it forgives your entire remaining balance after just 10 years of qualifying payments while working in public service, and that forgiveness is permanently tax-free.
Understanding these options before choosing a repayment plan can save tens of thousands of dollars. If you are also evaluating how student loan debt affects your ability to qualify for a mortgage, pair this calculator with the Debt-to-Income Ratio Calculator to see how your monthly IDR payment factors into your DTI ratio.
How to use this Loan Forgiveness calculator
Enter your Current Loan Balance — the total outstanding federal student loan balance, not your original loan amount. Find this at studentaid.gov. Include all federal loans you plan to consolidate or that are already in the Direct Loan program.
Enter your Annual Gross Income — your total pre-tax income from all sources. If you have a job offer, use the starting salary. For self-employed borrowers, use adjusted gross income. Remember: this is used to calculate IDR payments, so accuracy matters.
Set your Family Size — include yourself plus any dependents you claim for tax purposes. Adding a spouse or child raises the poverty line threshold and lowers your discretionary income, reducing your payment. Update this annually when you recertify.
Select your Repayment Plan — choose from SAVE, PAYE, IBR, ICR, or PSLF. For most borrowers with newer loans, SAVE typically produces the lowest payment. For those in qualifying public service jobs, PSLF almost always produces the best long-term outcome. Try multiple plans to compare.
Enter the Loan Interest Rate — use your actual weighted-average interest rate. Federal undergraduate loan rates for 2024–2025 are 6.53%; graduate loans are 8.08%; PLUS loans are 9.08%. If you have multiple loans, StudentAid.gov shows your average rate.
Set Annual Income Growth — your projected annual salary increase. The Bureau of Labor Statistics reports average wage growth of 3–4% annually. Use a conservative rate (2–3%) for a cautious projection; a higher rate (5–6%) models an optimistic career trajectory.
Read the four outputs — compare Starting Monthly Payment against what you can afford. Check Total Amount Paid to find the least expensive plan. Note the Estimated Forgiveness Amount and its potential tax treatment. Confirm Years to Forgiveness aligns with your career timeline.
Formula & Methodology
2025 Federal Poverty Guidelines (continental US): FPL(n) = $15,650 + (n − 1) × $5,500 Where n = family size Discretionary income by plan: SAVE: Discretionary = max(0, Annual Income − 2.25 × FPL) PAYE / IBR / PSLF: Discretionary = max(0, Annual Income − 1.50 × FPL) ICR: Discretionary = max(0, Annual Income − 1.00 × FPL) Monthly IDR payment: Monthly Payment = Discretionary Income × Plan Rate% ÷ 12 Where Plan Rate = 5% (SAVE) · 10% (PAYE, IBR, PSLF) · 20% (ICR) Monthly balance update: Monthly Interest = Balance × (Annual Rate ÷ 100 ÷ 12) For SAVE: New Balance = max(0, Balance − max(0, Payment − Interest)) For others: New Balance = max(0, Balance + Interest − Payment) Forgiveness amount: If Balance > 0 after Forgiveness Years × 12 months → Forgiveness = remaining Balance If Balance reaches $0 before forgiveness date → Forgiveness = $0 (paid off early) Worked example: Loan balance: $45,000 · Annual income: $50,000 · Family size: 1 · Plan: SAVE · Rate: 6.5% FPL for family of 1: $15,650 · SAVE threshold: 2.25 × $15,650 = $35,213 Discretionary income: $50,000 − $35,213 = $14,787/yr Monthly payment: $14,787 × 5% ÷ 12 = $62/month Monthly interest accrual: $45,000 × 6.5% ÷ 12 = $244/month Since $62 < $244, SAVE interest subsidy covers $182/month — balance stays flat at $45,000 Over 20 years (240 payments): Total paid = $62 × 240 = $14,880 Forgiveness amount: $45,000 (the full original balance, never grew due to SAVE subsidy) Compare with PAYE (no interest subsidy): Balance grows to ~$108,000 over 20 years (negative amortization), but that larger balance is forgiven — with a potential tax bill. SAVE eliminates the balance growth problem entirely. Key assumptions: The calculator models the first-year payment based on current income, then grows income annually by the stated growth rate. It does not account for annual recertification deadlines, plan switching, loan consolidation requirements, or potential future changes to repayment plan rules. PSLF requires employer certification and consistent on-time qualifying payments — this calculator estimates financial outcomes, not PSLF eligibility.
