How to Use the SAVE vs RAP Calculator
This calculator compares your monthly student loan payments across five repayment plans: the new RAP plan, the defunct SAVE plan, IBR (New and Old), and the Standard 10-Year plan. Follow these steps:
- Enter your loan balance — the total federal student loan balance you currently owe.
- Set your interest rate — the weighted average interest rate across your loans. You can find this on studentaid.gov.
- Enter your AGI — your adjusted gross income from your most recent tax return (Form 1040, line 11).
- Set household size and dependents — household size affects the poverty level threshold used by SAVE and IBR. Dependents affect the RAP calculation ($50/month reduction per dependent).
- Choose your loan type — this affects the SAVE payment rate (5% for undergrad, 10% for grad) and forgiveness timeline.
- Review the comparison — look at monthly payments, total cost, forgiveness amounts, and the SAVE-to-RAP transition card.
Understanding Each Repayment Plan
RAP (Repayment Assistance Plan)
RAP replaces the SAVE plan starting July 1, 2026. It uses a simple sliding scale based on your total AGI rather than discretionary income. Payments range from $10/month (for AGI under $10,000) to 10% of AGI divided by 12 (for AGI over $100,000). Each dependent reduces your payment by $50/month. The minimum payment is $10. Unpaid interest is fully waived, so your balance never grows. Forgiveness comes after 30 years of payments.
SAVE (Saving on a Valuable Education)
SAVE was struck down by the 8th Circuit Court of Appeals on March 9, 2026, and is no longer available. It calculated payments based on discretionary income (AGI minus 225% of the federal poverty level) at a rate of 5% for undergraduate loans and 10% for graduate loans. Forgiveness was after 20 years for undergrad and 25 years for grad loans. Like RAP, it waived unpaid interest. This calculator shows SAVE for comparison purposes only.
IBR (Income-Based Repayment)
IBR comes in two versions. New IBR (for loans originated after July 1, 2014) uses 10% of discretionary income above 150% of FPL with forgiveness after 20 years. Old IBR (for loans before July 1, 2014) uses 15% of discretionary income with forgiveness after 25 years. Both are capped at the standard 10-year payment amount. Unlike RAP and SAVE, IBR does NOT waive unpaid interest, so your balance can grow if payments do not cover interest.
Standard 10-Year
The default repayment plan with fixed monthly payments over 10 years. This results in the highest monthly payment but the lowest total cost since you pay off the full balance with interest and receive no forgiveness.
Important Caveats About the SAVE-to-RAP Transition
- Forbearance months do not count. Time spent in SAVE forbearance does not count toward forgiveness under any plan.
- Interest capitalization risk. If you switch from SAVE forbearance to IBR before transitioning to RAP, any accrued interest during forbearance may capitalize (be added to your principal balance). If you wait for automatic RAP enrollment, interest during forbearance is waived.
- Income recertification. You will need to recertify your income when RAP begins. Your payment will be based on your most recent AGI.
- Tax bomb. Forgiveness under RAP after 30 years is taxable income under current law. Plan ahead for the potential tax bill by using our Student Loan Tax Bomb Calculator.
- PSLF remains available. If you work for a qualifying public service employer, Public Service Loan Forgiveness (PSLF) still provides tax-free forgiveness after 120 qualifying payments. You can make qualifying PSLF payments while on RAP or IBR.
