RAP vs IBR vs Standard: what each plan costs you
Enter your numbers. We run the Repayment Assistance Plan, Income-Based Repayment and the standard plan side by side, month by month, using the formulas in the law.
Year-by-year monthly payments
Estimates, not a bill. Your servicer calculates the real payment from your tax data. How the numbers are made: methodology. Every rule and its source: the rules.
How the three plans work
Repayment Assistance Plan (RAP)
RAP takes a percentage of your whole adjusted gross income: 1% if it is over $10,000, rising one point for every $10,000, up to 10% above $100,000. Divide by 12, then subtract $50 for each dependent. The payment is never less than $10. If you pay on time and your payment doesn't cover the month's interest, the unpaid interest is waived, and the government adds enough to cut your principal by up to $50. Whatever is left after 360 qualifying payments (30 years) is forgiven. The formula, step by step · The complete RAP guide.
Income-Based Repayment (IBR)
IBR charges 10% of your income above 150% of the federal poverty line (15% if you already owed a federal student loan on July 1, 2014), never more than the 10-year standard payment. Forgiveness comes after 20 years (25 for older borrowers). If any of your loans was paid out on or after July 1, 2026, IBR is closed to you. RAP and IBR compared.
Standard and Tiered Standard
A fixed monthly payment that pays the loan off. Loans from before July 1, 2026 use the 10-year Standard plan. If you have a newer loan, it is the Tiered Standard plan: 10, 15, 20 or 25 years depending on your balance. Tiered Standard explained.
