How this calculator works

Repayment Assistance Plan (from July 1, 2026): a base payment of 1% to 10% of adjusted gross income, rising a point for each $10,000 band ($120 a year at $10,000 or less), divided by 12, less $50 a month per dependent, and at least $10. Payments cover interest first; interest they don't cover is waived, and if principal falls by less than $50 in a month, the government credits the difference up to your payment. Anything left after 360 qualifying payments is cancelled.

Standard plan for loans from July 1, 2026: fixed payments over 10 years below $25,000 owed, 15 years to $50,000, 20 years to $100,000 and 25 years above.

Income-based repayment (new borrowers since July 2014): 10% of income above 150% of the poverty guideline ($15,960 for one person in 2026, plus $5,680 per extra person), never more than the 10-year standard payment; forgiven after 20 years.

What it assumes

  • Income grows at the rate you set and payments are recalculated yearly; one average rate for all loans.
  • IBR is only for loans made before July 1, 2026. It uses the 10% plan for newer borrowers; borrowers from before July 2014 pay 15% for 25 years.
  • Forgiven balances may count as taxable income under federal law; public service loan forgiveness, which is tax-free, isn't modeled.

Questions people ask

What is the Repayment Assistance Plan?

RAP is the income-driven plan created by the 2025 tax and budget law, available from July 1, 2026. Payments are 1% to 10% of income, less $50 per dependent, with unpaid interest waived and forgiveness after 30 years.

How much will my RAP payment be?

It depends on income: at $55,000 of adjusted gross income with no dependents, $229.17 a month; with one dependent, $179.17.

Is RAP better than the standard plan?

Lower payments, but often more paid in total if your income rises. On $40,000 at 6.5% with $55,000 of income, standard costs $62,720 over 15 years; RAP costs $66,262.

What happens to SAVE, PAYE and ICR?

The 2025 law closes them to new enrollment and moves existing borrowers to other plans by July 1, 2028. Loans made from July 1, 2026 can use only the standard plan or RAP.

Does RAP forgive my loans?

Any balance left after 360 qualifying payments (30 years) is cancelled. Payments under other plans before switching can count toward the 360.
