Project your 120-payment finish line vs paying it off or refinancing
| Path | Monthly | Total Paid | Months | Tax on Forgiven |
|---|---|---|---|---|
| PSLF on IBR (10%) | $258.83 | $31,060 | 120 | None (§108(f)) |
| 10-year standard plan | $909.61 | $109,153 | 120 | None — paid in full |
| Refinance at 5.5% / 10 yr | $868.21 | $104,185 | 120 | None — paid in full |
Same $80,000 balance, same clock, $73,000 to $78,000 difference in what leaves your wallet. That's the entire PSLF case: a decade of qualifying employment converts loan repayment from a balance problem into an income problem.
| Counts | Doesn't Count |
|---|---|
| On-time payments on IBR, PAYE, ICR (RAP adds July 2026) | Months in default |
| 10-year standard plan payments | Most forbearance and deferment months |
| Months at any qualifying employer (gaps don't reset) | Months at for-profit employers |
| Full-time service (generally 30+ hrs or full-time contract) | In-school and grace-period months |
| Extra amounts paid beyond the due amount don't advance the date faster | Late or partial payments |
Certify employment annually through the PSLF Help Tool so the count is official, not remembered. Borrowers parked in SAVE forbearance should move to IBR, PAYE, or ICR to restart qualifying months.
PSLF math is upside-down from normal loan math: the lower your payment and the higher your balance, the more the program does for you. This calculator projects your finish line — payment 120 — and prices the alternative paths so the comparison is honest.
Your qualifying payment is estimated from the IBR formula: discretionary income = AGI − 150% of the 2026 poverty guideline for your family size and state; the payment is 10% (new-borrower IBR) or 15% (older-borrower IBR) of that, divided by 12. The calculator then amortizes your current balance at your rate for the remaining (120 − payments made) months. If the payment is below accruing interest, the balance grows — and that growth is what gets forgiven. The standard path prices a 10-year payoff of today's balance; the refinance path prices a private loan at your entered rate and term. ICR and the new RAP use different payment formulas, so treat those projections as directional.
Pull your official qualifying count from your servicer or the PSLF Help Tool rather than guessing — undercounts are common and fixable. Enter AGI from your last tax return, your family size, and your average rate across loans (the consolidation calculator shows how a weighted average works). Then test scenarios: a raise, a larger family, a return to grad school. The forgiveness number moves with every input.
A teacher with $80,000 of Direct loans at a 6.53% average rate has 30 qualifying payments on record and $55,000 of AGI, single, in the 48 states. Discretionary income: $55,000 − $23,940 (150% of the guideline) = $31,060. New-borrower IBR payment: 10% ÷ 12 = $258.83 a month. Monthly interest on $80,000 at 6.53% is $435, so each payment falls about $176 short and the balance quietly climbs. After the remaining 90 payments, the balance reaches roughly $100,426 — forgiven in full, tax-free. Total out of pocket over the whole 120 months: $31,060. The 10-year standard plan on the same balance costs $909.61 a month and $109,153 total; refinancing at 5.5% still costs $104,185 and, critically, surrenders the program. PSLF saves about $78,000 here, without a single dollar of it being taxed.
Flip the lens: without qualifying employment, that same IDR payment becomes a tax bomb instead — balance grows for 20-25 years, then discharges as taxable income. The tax bomb calculator prices that path, and the refinance calculator handles the break-even if you do leave public service.
Education only, not legal or financial advice. Qualifying-payment rules are set by ED regulation and program guidance; verify your official count with your servicer.
120 qualifying monthly payments while working full-time for a qualifying employer — government, 501(c)(3) nonprofit, or certain other nonprofits — roughly 10 years. They don't have to be consecutive; the count only advances during months you're employed, on a qualifying plan, and paying on time. Payments made while in default, in most forbearances, or in school don't count.
Any income-driven plan (IBR, PAYE, ICR) and the 10-year standard plan earn qualifying payments, and the new Repayment Assistance Plan counts starting July 1, 2026. The blocked SAVE plan put borrowers into forbearance, and forbearance months don't count — if you're parked there, switching to IBR, PAYE, or ICR restarts your progress. The 10-year standard technically qualifies but at a payment that leaves nothing to forgive.
No federal tax, ever: PSLF is excluded from gross income under IRC Section 108(f), a permanent provision independent of the temporary ARPA window that expired in 2025. That's a structural advantage over IDR forgiveness, which became federally taxable again in 2026. One exception: Mississippi taxes PSLF forgiveness at the state level.
No — refinancing federal loans into a private loan permanently forfeits PSLF, IDR options, and federal protections. If your PSLF projection shows a large forgiveness amount at a low IDR payment, refinancing away that path almost always costs more. Refinancing only makes sense if you're abandoning PSLF, for example after leaving public service for good.
Nothing is lost. The count pauses while you're at a for-profit or self-employed, and resumes when you return to qualifying employment — months at the private job simply don't advance it. Certify employment periodically with the PSLF Help Tool so every qualifying month is on record before memory fades.
No — on PSLF, negative amortization is the engine, not a bug. If your payment is below monthly interest, the balance grows, and more gets forgiven at payment 120. The math that makes IDR dangerous for private-sector borrowers (a bigger balance, taxed at discharge) is reversed here: the excess is wiped out tax-free.
