How to Use This Calculator
Tab "Compare Plans"
Enter your loan balance, interest rate, annual income (AGI), and family size. The calculator models every available federal repayment plan side-by-side โ Standard, Graduated, Extended, IBR, PAYE, ICR, and the upcoming RAP โ with year-by-year income growth projections. Each plan shows monthly payment in year 1, total paid, forgiveness amount, the tax you'll owe on that forgiveness, and net cost. Check the PSLF box if you work for government or a 501(c)(3) to see tax-free 10-year forgiveness options.
Tab "PSLF Tracker"
If you're pursuing Public Service Loan Forgiveness, enter your current balance, qualifying payments already made (0โ120), and your repayment plan. The tracker shows exactly how many payments remain, your projected monthly payment with income growth, total you'll pay before forgiveness, the amount forgiven (tax-free under PSLF), and savings compared to standard 10-year repayment. The progress bar shows where you stand on the road to 120 payments.
Tab "Refinance Check"
Considering a private refinance for a lower rate? Enter your current federal rate and the private refinance rate you'd qualify for. The calculator compares keeping federal loans (best IDR plan) vs. refinancing โ side-by-side with monthly payments, total cost, forgiveness potential, and protections lost. Color-coded verdict: green (refinancing clearly saves money), yellow (risky trade-off), or red (don't do it).
The Plans Explained (March 2026)
Graduated: Starts at ~60% of Standard, increases ~15% every 2 years. Same 10-year term. Good if your income is low now but rising fast.
Extended (25-Year): Fixed payments over 300 months. Requires balance > $30,000. Lower monthly payment, but much more interest.
ICR (Income-Contingent): 20% of discretionary income (AGI โ 100% FPL). 25-year forgiveness. Most generous poverty line threshold.
IBR (Income-Based): Pre-July 2014 borrowers: 15% of discretionary income (AGI โ 150% FPL), 25-year forgiveness. Post-July 2014: 10%, 20-year forgiveness.
PAYE (Pay As You Earn): 10% of discretionary income (AGI โ 150% FPL), capped at Standard payment. 20-year forgiveness. Closes to new enrollees June 30, 2028.
SAVE: Permanently ended by 8th Circuit court order, March 9, 2026. Enrolled borrowers are in administrative forbearance and must choose another plan.
RAP (Repayment Assistance Plan): Opens July 1, 2026 under OBBBA. Bracketed 1โ10% of total AGI, $50/dependent deduction, $10/mo minimum. 30-year forgiveness. Final rules not yet published.
The Formulas
ICR: DI = max(0, AGI โ 1.00 ร FPL)
IBR/PAYE: DI = max(0, AGI โ 1.50 ร FPL)
2026 Federal Poverty Level (48 contiguous states):
FPL = $15,960 + (family size โ 1) ร $5,680
Alaska: $19,950 + (nโ1) ร $7,100 ยท Hawaii: $18,360 + (nโ1) ร $6,530
IDR Monthly Payment:
IBR (pre-2014): min(DI ร 15% / 12, Standard 10-yr payment)
IBR (post-2014): min(DI ร 10% / 12, Standard 10-yr payment)
PAYE: min(DI ร 10% / 12, Standard 10-yr payment)
ICR: min(DI ร 20% / 12, 12-year standard payment)
RAP (Jul 2026):
Bracketed: โค$10K โ $120/yr flat; $10Kโ$20K โ 1%; $20Kโ$30K โ 2%; ... $90Kโ$100K โ 9%; >$100K โ 10%
Monthly = max($10, AGI ร bracket% / 12 โ $50 ร dependents)
Income Growth Projection:
AGIyear = AGI ร (1 + growth rate)year
IDR payment recalculated each year with updated AGI โ this is the key differentiator.
Tax Bomb on Forgiveness (post-ARPA, effective Jan 1, 2026):
Forgiven amount added to AGI in forgiveness year
Tax = marginal rate at (projected AGI + forgiven amount)
Exception: PSLF forgiveness is tax-free. Death and disability forgiveness are tax-free.

Example
Jason โ Software Engineer in Austin, TX
$45,000 in federal student loans at 6.39%, starting salary $65,000, growing 5%/year. Single, family size 1.
Without PSLF, PAYE costs Jason $7,350 less than Standard โ even after the tax bomb. But if Jason takes a government job, PSLF saves him $27,600 total. The income growth modeling matters: at 5%/year, Jason's payments climb from $220 to $430 by year 10. Static-income calculators miss this completely.
