Standard vs IBR vs RAP (2026) — your monthly payment, payoff date & total interest.
SAVE was struck down (Mar 2026). RAP is the new income-driven plan starting Jul 1, 2026.

Adjusted Gross Income from your latest tax return.

AK & HI use higher poverty guidelines.
IBR payment is capped at this Standard payment.
RAP only: −$50/mo per child ($10 floor).
Estimate only — not financial advice. This is an educational estimate, not an official Department of Education determination. Your real payment is set by your loan servicer using verified tax data. RAP rules (percentages, the $50/dependent reduction, $10 floor, $50 principal match, unpaid-interest waiver, and 360-payment forgiveness) come from the One Big Beautiful Bill Act (P.L. 119-21) and take effect July 1, 2026. SAVE was vacated by federal court on March 10, 2026 and is intentionally not offered. All math runs in your browser — nothing is sent anywhere.
This calculator models the four repayment options that matter after the 2026 overhaul: Standard (10-yr), IBR (new, 10% / 20-yr forgiveness), IBR (old, 15% / 25-yr), and the new RAP plan. It computes your monthly payment, runs a month-by-month amortization for the payoff date and total interest, shows a side-by-side comparison against the Standard plan, and (for income-driven plans) projects the balance forgiven at the plan's horizon. An optional extra payment shows your time and interest saved.
M = P·i / (1 − (1+i)⁻ⁿ) where i = APR/12, with a $50 federal minimum.A borrower owes $38,000 at 6.53% APR. On the Standard
10-year plan, the monthly rate is 6.53% / 12 = 0.0054417. Over 120 months the
payment is 38,000 × 0.0054417 / (1 − 1.0054417⁻¹²⁰) ≈ $432.06/mo. The first month's
interest is $38,000 × 0.0054417 ≈ $206.78, so about $207 goes to interest and
$225 to principal in month one. Over the full term the borrower pays roughly
$13,850 in interest for a total of about $51,850, finishing in 10
years. Switching to RAP at a $55,000 AGI would drop the monthly payment to about
5% × $55,000 / 12 = $229/mo — lower now, but stretched over up to 30 years with any
remainder forgiven.

Standard (10-yr), IBR new (10% / 20-yr) and old (15% / 25-yr), and the new RAP plan effective July 1, 2026. SAVE, PAYE, and ICR are intentionally excluded because they are being phased out.
A sliding 1%–10% of your total AGI (rising one point per $10,000 of income), divided by 12, minus $50 per dependent child, with a $10 floor. Unpaid interest is waived rather than capitalized, and any balance after 360 payments is forgiven.
IBR pays 10% or 15% of discretionary income (AGI minus 150% of the federal poverty line) and is capped at the 10-year Standard payment. RAP pays a percentage of total AGI with no poverty offset and no Standard cap.
It may be treated as taxable income depending on the law in effect when forgiveness occurs. We show the projected forgiven amount but do not estimate any tax — consult a tax professional.
Under RAP, if your payment doesn't cover the month's interest, the unpaid interest is waived (not added to your balance), and a small principal match keeps the balance from growing. With very low income the balance can stay flat until it is forgiven at 30 years.
