Student Loan Forgiveness Calculator – Calculate PSLF & IDR Forgiveness | SoCalSolver

Calculate student loan forgiveness: PSLF (10 years), IDR forgiveness (20-25 years), monthly payments, tax liability, and forgiveness timelines. Works for federal Direct Loans, FFEL, and Perkins.

Federal student loan forgiveness offers two major pathways: Public Service Loan Forgiveness (PSLF) for government and nonprofit employees, and Income-Driven Repayment (IDR) forgiveness for any federal loan borrower. The PSLF program forgives remaining loan balance after 10 years of payments (120 qualifying monthly payments) with no federal income tax liability. IDR forgiveness forgives remaining balance after 20-25 years, but forgiveness may be subject to income tax.

This calculator helps you estimate monthly payments under various repayment plans, project total interest costs, calculate forgiveness amounts, assess tax liability, and compare PSLF versus IDR scenarios. The choice between these pathways—and the repayment plan you select—can impact your financial outcome by tens of thousands of dollars. Understanding discretionary income calculations, employment sector requirements, and loan consolidation rules is critical to maximizing forgiveness benefits.

Whether you're a public servant considering PSLF, a nonprofit employee with dual-benefit options, or a private sector borrower pursuing IDR forgiveness, this calculator provides realistic projections based on 2025 federal guidelines, current interest rates, and regulatory requirements.

Methodology

The PSLF calculation is straightforward: 120 qualifying monthly payments (non-consecutive) while employed full-time in a qualifying position (government agency, 501(c)(3) nonprofit, or military). The critical metric is employment sector and payment count, not the amount paid monthly. This creates a counterintuitive benefit: lower monthly payments (achieved through income-driven repayment plans) mean minimal principal reduction, more interest accrual, and larger balance remaining for forgiveness at the 120-payment mark.

Income-Driven Repayment (IDR) monthly payments are calculated using the formula: (Adjusted Gross Income - Poverty-Guideline-Adjusted Threshold) × Payment Percentage ÷ 12. The poverty guideline is 150% for SAVE/PAYE/REPAYE plans, 100-200% for IBR and ICR. Payment percentages range from 5% (SAVE plan, newest) to 20% (ICR). SAVE (2024) is most favorable with 5-10% rates and built-in interest accrual suspension if you pay the calculated minimum. Family size matters: a family of 4 has a higher poverty guideline threshold than a single borrower, resulting in lower discretionary income and lower payment.

Tax treatment differs critically between pathways: PSLF forgiveness is tax-free under current statute. IDR forgiveness at the 20-25 year mark has historically been treated as cancellation of debt income and potentially taxable; however, statutory and administrative changes may change tax treatment. This calculator provides an estimated tax liability field for IDR forgiveness scenarios — treat the estimate as illustrative and consult a tax professional before relying on it.

Loan consolidation rules affect PSLF eligibility: Direct Loans are immediately eligible for PSLF. FFEL and Perkins loans must be consolidated into a Direct Consolidation Loan to become PSLF-eligible. Consolidation can reset the 120-payment counter. Strategic timing of consolidation matters; consult your servicer and consider employer certification history before consolidating.

Interest accrual calculations use standard amortization formulas with monthly compounding at the stated annual interest rate. During income-driven repayment, monthly interest accrual may exceed monthly payment amounts, causing negative amortization if interest capitalizes. SAVE plan includes interest accrual protections for many borrowers; verify specifics with Federal Student Aid or your servicer.
