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.
Why Use a Student Loan Forgiveness Calculator?
Student loan repayment decisions are among the highest-stakes financial choices American borrowers make, yet most borrowers choose a repayment plan without modeling the long-term cost. A forgiveness calculator makes the consequences of each choice concrete.
Compare plans side by side. SAVE vs PAYE vs PSLF can produce vastly different total costs for the same borrower. A teacher with $60,000 in loans and a $45,000 salary might pay $30,000 total under PSLF (10 years), $42,000 under SAVE (20 years, with forgiveness), or $80,000 under a standard 10-year plan. These are not marginal differences, they determine whether you can afford a home, start a business, or save for retirement.
Model your income growth. The Annual Income Growth Rate input lets you project what happens as your salary increases over 20 years. Higher income growth means larger future payments, which may eliminate the forgiveness benefit. Running the calculator at 2%, 3%, and 5% income growth shows how sensitive your outcome is to career trajectory.
Understand the interest subsidy on SAVE. Under PAYE and IBR, if your payment does not cover monthly interest, unpaid interest capitalizes onto your balance, your forgiveness amount grows, and so does the potential tax bill. SAVE eliminates this entirely. The calculator models each plan's interest behavior separately so the comparison is accurate.
Check PSLF viability. If you work in a qualifying public service role, 10-year PSLF forgiveness is almost always superior to 20–25-year IDR forgiveness, both the timeline and the tax treatment are better. The calculator shows how dramatically lower the total paid can be on PSLF versus IDR.
Who Should Use This Calculator?
Recent graduates with federal student loans considering IDR enrollment. If you have graduated and are deciding between standard repayment and an IDR plan, running this calculator with your starting salary shows the immediate payment difference and the long-term forgiveness trajectory. The choice made at loan servicer enrollment compounds over decades.
Borrowers currently on standard 10-year repayment reconsidering their plan. Many borrowers who can afford standard payments still benefit from switching to an IDR plan, particularly those pursuing PSLF, or those in professions with expected income plateaus (social work, teaching, government, non-profit sector) where high forgiveness amounts are achievable. This calculator quantifies that benefit.
Public servants evaluating PSLF eligibility. For teachers, nurses, government employees, non-profit workers, and other public service professionals, PSLF can be transformative. The calculator's PSLF option shows the 10-year payment total against the forgiven amount, making the argument for pursuing PSLF (and ensuring correct employer certification) immediately visible.
Borrowers with high debt-to-income ratios. If your loan balance significantly exceeds your annual income, a common situation for graduate school borrowers, IDR plans often produce payments that will never fully cover interest on a standard schedule. SAVE's interest subsidy is critical for this group, and this calculator shows exactly how much balance protection it provides.
Financial advisors and student loan counselors. The calculator's shareable URL (automatically updated as you adjust inputs) lets advisors send clients a pre-filled scenario for their specific situation, a more concrete conversation-starter than generic repayment tables.
What Insights Does the Student Loan Forgiveness Calculator Give You?
Starting Monthly Payment is the first-year monthly obligation under your chosen IDR plan, based on your current income and family size. This is what you actually pay initially. As your income grows (per the Annual Income Growth Rate), future payments increase, the calculator models the entire trajectory. If the starting payment is $0 (income below the poverty threshold), the calculator models that accurately.
Total Amount Paid is the cumulative sum of all monthly payments from year one to forgiveness, the actual dollars you write to your loan servicer over the life of the plan. Comparing total paid across plans (especially PSLF vs IDR) often reveals the most impactful insight: PSLF's 10-year timeline typically produces a much lower total paid, even though the monthly payment is similar to other IDR plans.
Estimated Forgiveness Amount is the remaining balance discharged at the end of your plan's term. For SAVE, PAYE, and IBR, note that forgiven IDR balances may be treated as taxable income after 2025. For PSLF, the forgiveness is permanently tax-free. A large forgiveness amount on an IDR plan is not free money, budget for a potential tax bill in the forgiveness year.
Years to Forgiveness shows how long until you reach the forgiveness date. For PSLF this is always 10 years; for SAVE/PAYE/IBR it is 20 years; for ICR it is 25. If your balance reaches zero before this date (because growing income drives payments high enough), the calculator reports an earlier payoff date with $0 forgiveness.
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.
