Answer: Enter the amount, rate, and term and the RAP Payment on a $50,000 Salary returns your exact periodic payment with a full amortization breakdown of principal versus interest.
$166.67 a month at 4% of AGI, before dependent credits
The full calculation: $50,000 falls in the $40,001-$50,000 band, where RAP charges 4% of total income. That's $2,000 a year, or $166.67 a month. Dependents subtract $50 each. Tweak the inputs to see your exact household:
| Dependents | Monthly Payment | Math |
|---|---|---|
| 0 | $166.67 | 4% × $50,000 ÷ 12 |
| 1 | $116.67 | − $50 credit |
| 2 | $66.67 | − $100 credit |
| 3 | $16.67 | − $150 credit |
| 4+ | $10.00 | $10 floor applies |
| Path | Monthly | 20-Year Total |
|---|---|---|
| RAP, no dependents | $166.67 | $40,000 |
| Standard 10-yr, $30,000 balance @ 6.39% | $338.97 | $40,676 (paid in 10) |
| Standard 10-yr, $50,000 balance @ 6.39% | $564.95 | $67,793 (paid in 10) |
At $50,000 of income, RAP roughly halves a typical standard payment. But note the totals: on a $30,000 balance, RAP's slow drip actually costs about the same as just paying the loan off in 10 years, and standard plan finishes a decade sooner.
| AGI band | Rate | Monthly payment (no dependents) |
|---|---|---|
| Up to $10,000 | 0% | $10.00 (minimum payment applies) |
| $10,001–$20,000 | 1% | $16.67 at $20,000 |
| $20,001–$30,000 | 2% | $50.00 at $30,000 |
| $30,001–$40,000 | 3% | $100.00 at $40,000 |
| $40,001–$50,000 | 4% | $166.67 at $50,000 — this page |
| $50,001–$60,000 | 5% | $208.34 at $50,001 · $250.00 at $60,000 |
| $60,001–$70,000 | 6% | $350.00 at $70,000 |
| $70,001–$80,000 | 7% | $466.67 at $80,000 |
| $80,001–$90,000 | 8% | $600.00 at $90,000 |
| $90,001–$100,000 | 9% | $750.00 at $100,000 |
| Above $100,000 | 10% cap | $1,250.00 at $150,000 |
Read the bands carefully: the percentage applies to your actual income, so a payment grows inside a band as income rises, then jumps a point when you cross the next $10,000 line. At $45,000 you are already at 4% ($150.00); $50,000 is simply the top of the band — the most a 4% borrower can be charged before the 5% band takes over.
Two floors bound the scale at the bottom. Income at or under $10,000 pays the $10 minimum rather than nothing, and dependent credits ($50 each) can pull a payment down to that same $10 floor but no lower. A $50,000 borrower with three dependents lands at $16.67 for exactly that reason — the credits chew through the 4% charge and the floor catches what's left.
Fifty thousand dollars sits at the top of the 4% band, which makes it a useful reference point: one dollar more and the percentage jumps to 5. A single borrower at exactly $50,000 pays $166.67 every month, recertified annually against their tax return. Raise to $54,000 next year and the payment stays at 4% of the new total ($180.00), because the band, not the dollar, sets the rate until income crosses $60,000.
Two traps are worth naming. First, the dependent credit is per dependent, so a $50,000 earner with three kids pays $16.67, effectively the floor; family size is a bigger lever than salary at this income. Second, RAP payments at $166.67 may not even cover interest on a large balance. The plan subsidizes unpaid interest so the balance doesn't grow, but that subsidy has limits under Department rules, so confirm with your servicer how your specific balance behaves.

$166.67 a month with no dependents. The Repayment Assistance Plan charges 4% of AGI in the $40,001-$50,000 band, so $50,000 × 4% = $2,000 a year, divided by 12. Each dependent subtracts $50, so one dependent pays $116.67 and two pay $66.67. At four dependents the $10 floor takes over.
Usually yes, if the standard payment would strain you. A $30,000 loan balance at the 2025-26 undergrad rate of 6.39% costs $338.97 a month on the 10-year standard plan; RAP caps you at $166.67 regardless of balance. The catch is time: at $166.67, 20 years of payments total $40,000, and only the leftover balance is forgiven at that point.
Each $10,000 band adds a percentage point. At $50,001 you jump to the 5% band, and the payment for that specific income is $208.34. At $60,001 it becomes 6% and $300.00. You recertify income annually, so raises phase in a year at a time, not mid-year.
No. The scale bottoms out at a $10 minimum monthly payment, which applies even at income of $10,000 or less. Dependent credits can reduce what the percentage charges, but they stop at the same $10 floor — they cannot take a payment to zero.
Adjusted gross income as it appears on your tax return. That is why payments are described in AGI bands, and why the plan recertifies annually against your latest return: a raise shows up a year later, once the new AGI is on file, rather than mid-year.
