§02 · The math

How we got there.

RAP starts with your combined income, picks a bracket, then splits the result between you based on each spouse’s share of the loan balance.

  1. 1
    Combined AGI sets the bracket
    At $95,000, you’re in the $90,001–$100,000 (9%) bracket. The whole AGI gets that rate (it’s bracketed, not marginal).
  2. 2
    Annual base → monthly
    9% of $95,000 = $8,550/year ÷ 12 = $712.50/month.
  3. 3
    Dependent reduction
    No dependents claimed, so no reduction. Household payment before splitting: $712.50/month.
  4. 4
    Proration between spouses
    The household payment splits by each spouse’s share of the eligible federal balance.
  5. 5
    $10 floor check
    Both shares are above the $10 minimum, so no adjustment needed.
Borrower 1
$712.50 × 60.0% = $427.50
$427.50/mo
Borrower 2
$712.50 × 40.0% = $285.00
$285.00/mo

How RAP handles marriage

The Repayment Assistance Plan launches July 1, 2026. It uses a tiered percentage of AGI — 1% at the bottom, climbing to 10% above $100,000 — rather than the discretionary-income formula older IDR plans use. Married couples need to understand four moving parts:

Filing jointly pools your income
Filing MFJ means RAP looks at your combined AGI to pick the bracket. That generally puts you in a higher bracket than either of you would hit alone.
Filing separately uses just your income
Filing MFS means each of you runs the calculation independently — your own AGI, your own dependents, your own loan balance. Spouses with widely different incomes often pay less under MFS, but you lose tax benefits like the Earned Income Credit and education credits.
Proration splits the household payment — but only sometimes
When you file jointly and both spouses have eligible federal loans, the household payment is split between you in proportion to your share of the combined loan balance. If one spouse has no federal loans, no proration applies — the borrowing spouse pays the full household amount calculated on combined income.
The $50 dependent reduction comes off before splitting
For each dependent claimed on your tax return, RAP knocks $50/month off the payment. Under MFJ, the reduction comes off the household payment before it’s split between spouses. Under MFS, each spouse’s reduction applies only to their own payment.
Every payment has a $10 floor
No monthly payment can be less than $10, even after dependent reductions and proration. If your share would otherwise come out below $10, the regulation rounds it up.
