RAP Student Loan Calculator

RAP is a new federal income-driven student loan repayment plan, created by the 2025 reconciliation law (the 'One Big Beautiful Bill'), that became available July 1, 2026. It's the only income-driven plan open to new Direct Loan borrowers going forward, alongside the legacy IBR plan.

Monthly payment = (AGI × bracket rate ÷ 12) − ($50 × number of dependents), with a $10/month minimum. The bracket rate starts at 1% of AGI for incomes of $10,001-$20,000 and rises by 1 percentage point per $10,000 bracket, up to 10% of AGI for incomes above $100,000.

Under RAP, any interest not covered by your payment is waived — your balance won't grow from unpaid interest the way it could under some other plans. If your payment reduces principal by less than $50, the government contributes the difference (up to $50) toward your principal balance.

Any remaining balance is forgiven after 360 qualifying monthly payments (30 years).

RAP uses a straightforward bracket-of-AGI formula, while IBR uses discretionary income (AGI minus 150% of the poverty line) at a flat 10% or 15%. Which is cheaper depends on your specific income, family size, and loan balance — use both this calculator and the IBR Calculator to compare, or check the official studentaid.gov Loan Simulator.
