Key Summary

Under Public Service Loan Forgiveness, full-time government and 501(c)(3) nonprofit employees with Direct Federal Loans receive 100% tax-free forgiveness after 120 qualifying monthly payments on an IDR plan. On $50,000 at 6.0% with $500 monthly and 60 payments remaining (60 already credited), you pay $30,000 more and about $34,800 of principal and interest is forgiven. Paying $300 monthly instead leaves $30,000 unpaid interest to be capitalized, and $18,000 is paid over the same 60 months with $48,000 forgiven. According to Federal Student Aid, PSLF requires 120 payments; see studentaid.gov. Enter your balance and payment below.

How to Use the Student Loan Forgiveness Calculator

1

Choose Reference Program

Select PSLF 120 payments, IDR 20-year 240 payments or IDR 25-year 300 payments. PSLF is tax-free; IDR forgiveness after 20/25 years may be taxable in that year.

2

Enter Current Balance and Weighted Rate

Enter the eligible balance such as $50,000 and weighted fixed rate like 6.0%. At 6.0% monthly interest is $250 on $50,000, so a $500 payment covers interest plus $250 principal.

3

Enter Expected IDR Payment

Enter the monthly payment from your servicer IDR calculation, for example $500. Payments below $250 on $50,000 at 6% allow the balance to grow and increase the forgiven amount later.

4

Add Qualifying Payments Already Credited

Enter the count from StudentAid.gov, such as 60 credited. Remaining payments are 120 minus 60 = 60 for PSLF, or 240 minus 60 = 180 for 20-year IDR.

5

Review Projected Forgiven Amount and Total Paid

Check the simulated balance path, total out-of-pocket and projected forgiven principal plus interest, then test a $200 payment change.

The formula
For each remaining month: Interest = Balance × (annual rate/12) | Balance next = Balance + Interest − Payment | Forgiven = Balance after N remaining months (floored at 0)
Balance
Outstanding eligible principal at the start of the month.
r
Monthly rate = annual rate /12 as a decimal.
Payment
Expected IDR or standard payment that month.
N
Remaining qualifying payments = program reference (120/240/300) minus already credited.
Forgiven
Projected remaining balance after N payments, simulated month by month.

Will I Qualify for PSLF or IDR Forgiveness?

Forgiveness is a payment-count milestone, not an automatic balance. For PSLF, the U.S. Department of Education requires 120 qualifying monthly payments while working full-time for a qualifying government or 501(c)(3) nonprofit employer, with Direct Loans on a qualifying IDR plan and employment certification on file (Source: Federal Student Aid, studentaid.gov/pslf). For IDR, the 20-year 240-payment or 25-year 300-payment reference depends on plan: SAVE/PAYE undergraduate often 240, graduate and ICR 300. The calculator simulates the balance to that reference count; it does not certify that your loans, plan or employment qualify.

Check your official counts at StudentAid.gov and resolve discrepancies through the servicer. A $50,000 balance at 6% with $500 IDR for 60 months has $34,800 projected forgiven; the same balance with $300 has $48,000 projected forgiven because less principal is repaid before the count. Use the Student Loan Calculator to see the standard 10-year $398 payment versus IDR.

How Much Will Be Forgiven and Is It Taxable?

The forgiven amount is the remaining principal plus any accrued interest after the reference payments are simulated. At $50,000 6% with $500 for 60 remaining PSLF months, forgiveness is about $34,800; at $300 it is about $48,000 with $18,000 paid versus $30,000 paid. PSLF forgiveness is federally tax-free, while IDR forgiveness after 240 or 300 payments is generally taxable as ordinary income in the forgiveness year under current IRS rules (Source: IRS Publication 4681, irs.gov). On a $48,000 IDR forgiven amount at 22% marginal, the federal tax could be about $10,560 in that year.

States vary: some exclude student loan forgiveness, others follow federal inclusion. Model the tax as 22% of the projected forgiven amount and reserve that cash separately so the forgiveness year does not become a new debt.

PSLF vs IDR vs Aggressive Payoff: Which Strategy Costs Less Total?

Total out-of-pocket is payments made plus any tax on forgiven debt. For a borrower with $50,000 at 6% and 60 already credited: PSLF at $500 for 60 more costs $30,000 total with $34,800 tax-free forgiven; IDR 20-year with $350 for 180 more costs $63,000 with about $28,000 forgiven but $6,160 tax at 22%; aggressive payoff of the $398 standard 10-year costs $47,776 total with $0 forgiven and $12,776 interest.

StrategyPayments remainingCash paidForgivenNet after 22% tax*
PSLF $50060$30,000$34,800$30,000
IDR $350180$63,000$28,000$69,160
Standard payoff $39860*$47,776†$0$47,776

PSLF wins when employment qualifies; otherwise the tax on IDR forgiveness often makes aggressive payoff cheaper despite no forgiveness. Compare net cost after tax, not just forgiven dollars, with the Debt-to-Income Ratio Calculator to see DTI impact.

What Happens If My Payment Is Less Than Monthly Interest?

When payment is below monthly interest, the balance grows — negative amortization. At 6% on $50,000, monthly interest is $250. At $300 payment, only $50 reduces principal the first month, leaving $49,950. Over 60 months the balance barely falls, so forgiveness is large but you pay $18,000 to service $48,000 later. At $200 payment, $50 of interest is unpaid monthly and the balance rises about $3,000 in the first year alone (Source: Federal Student Aid interest accrual — studentaid.gov).

Some IDR plans like SAVE subsidize unpaid interest so the balance does not grow, but that provision is subject to 2026 litigation and not guaranteed. The calculator shows the balance path with simple monthly accrual without subsidies; actual servicer capitalization and subsidy rules can make the real balance lower. Verify whether your plan covers unpaid interest before counting on forgiveness.
