How to use this RAP calculator
Enter your Adjusted Gross Income (AGI) from Form 1040 line 11 and the number of dependent children. The calculator shows your RAP monthly payment, the income-bracket rate that applies, and a side-by-side comparison with IBR.

How RAP calculates your payment — the two-step formula
RAP uses your Adjusted Gross Income (AGI) and number of dependent children. It is simpler than IBR because it operates on your full AGI (not discretionary income), and the rate is determined by which income bracket you fall into.
Subtract $50 per dependent child per month from the base monthly payment. Minimum is $10/month regardless of dependents.
RAP vs IBR — side-by-side comparison
RAP and IBR each produce lower payments in different situations. RAP applies a rate (1–10%) to your full AGI. IBR applies 10–15% to your discretionary income (AGI minus 150% of the federal poverty line for your household size). For larger households, IBR's poverty-line deduction grows significantly. Use the calculator above to compare your specific situation.
- 1–10% of full AGI (1% per $10K increment)
- $50/month per dependent child reduction
- Minimum $10/month payment floor
- Mandatory for new Direct Loans (post-July 1, 2026)
- 30-year maximum repayment period
- 10% of discretionary income (post-July 2014 borrowers)
- 15% for pre-July 2014 borrowers
- Discretionary = AGI minus 150% of poverty line for household size
- No dependent child reduction
- Can be lower for larger households due to poverty-line deduction
When does RAP take effect — and who does it apply to?
RAP takes effect July 1, 2026. It was created by P.L. 119-21 (the FY2025 budget reconciliation law). RAP is the only income-driven repayment plan available for new Direct Loans originated on or after July 1, 2026.
RAP is the only IDR plan available for federal Direct Loans originated on or after July 1, 2026. Existing IBR borrowers who also take new loans must move all loans to RAP.
Required for new loansBorrowers currently on IBR, PAYE, SAVE, or ICR can choose to switch to RAP. IBR remains available for pre-2026 loans. Use the calculator to compare before switching.
Optional switchBorrowers on SAVE, ICR, and PAYE must switch to RAP or a standard repayment plan by July 1, 2026. IBR borrowers may remain on IBR.
Transition requiredRAP's two financial protections — interest subsidy and minimum principal paydown
RAP includes two built-in subsidies that distinguish it from older IDR plans on the interest side:
What happens at 30-year forgiveness — and the PSLF shortcut
Remaining balance is cancelled after 360 qualifying payments. The forgiven amount is treated as taxable ordinary income in the year of forgiveness.
RAP payments count toward PSLF's 120 qualifying monthly payments. After 10 years of qualifying public-service work, remaining balance is forgiven tax-free.
Critical RAP-to-IBR switch warning: If you switch from RAP to IBR, your RAP payment count does NOT transfer to IBR's forgiveness clock. The reverse is fine: prior IBR/ICR/PAYE payments count toward RAP's 30-year clock.
RAP has no payment cap — how high-income borrowers can end up paying more than standard repayment
IBR has a payment cap: your monthly payment can never exceed what you'd pay on the standard 10-year repayment plan. RAP has no such cap. For borrowers with high income and moderate loan balances, RAP payments can exceed both IBR and standard repayment.
| Scenario | RAP | IBR cap | Standard 10-yr | Winner |
|---|---|---|---|---|
| $40K AGI, $30K loan | $133/mo | $166/mo (capped) | ~$349/mo | RAP wins |
| $80K AGI, $30K loan | $533/mo | $349/mo (capped) | ~$349/mo | IBR = Standard |
| $120K AGI, $50K loan | $1,000/mo | ~$581/mo (capped) | ~$581/mo | IBR = Standard; RAP loses |
| $60K AGI, $80K loan (2 kids) | $250/mo (−$100) | $463/mo | ~$929/mo | RAP wins clearly |
RAP makes most sense when…
- You are on the PSLF track (any income level)
- Your income is low-to-moderate relative to debt
- You have 2+ dependent children reducing your payment
- Your RAP payment is below your standard 10-year payment
Standard repayment may cost less when…
- Your RAP payment exceeds your standard 10-year payment
- You have high income and a moderate loan balance
- You're not pursuing PSLF
- You want to pay off debt faster (10 years vs. 30)
Parent PLUS loans are excluded from RAP — urgent July 1, 2026 deadline
Parent PLUS loans are not eligible for RAP — and not eligible even after consolidation. Graduate PLUS loans (where the student is the borrower) are eligible.
