This free repayment assistance plan calculator (also a rap student loan calculator) estimates your Repayment Assistance Plan monthly payment from total AGI and dependents, then compares it with a standard 10-year payment. Multicalify is a rap calculator for student loans and an income driven repayment calculator for educational planning. No signup is required.
Browse loan tools under loans, finance calculators, and the calculators archive. Use the loan calculator and EMI calculator for amortizing payment structure, and the salary and tax calculator when AGI assumptions need a paycheck reality check.
Repayment Assistance Plan Calculator: key points
The repayment assistance plan calculator answers a repayment planning question: given income and household size, what approximate RAP payment appears, and how does it compare with a standard 10-year EMI? It is a RAP payment estimator, not an official servicer bill and not enrollment advice.
Who it helps
- Borrowers comparing RAP style income-driven payments with standard 10-year amortization
- Households testing how dependents change the monthly estimate
- People who need a free income driven repayment calculator sketch before reading StudentAid.gov
- Anyone stress-testing AGI changes against federal loan balance and rate
How to use the calculator
- Open the repayment assistance plan calculator and enter federal loan balance and weighted average interest rate.
- Enter your total AGI (combined AGI if married filing jointly).
- Enter dependents; each one lowers the monthly payment by $50.
- Optionally enter a known standard 10-year payment, or leave it blank to auto-estimate.
- Compare the RAP estimate with the standard payment and monthly interest line.
How the RAP estimate is calculated
RAP does not subtract a poverty line. Find the tier percent that matches your total AGI, multiply it by total AGI, and divide by 12. Each dependent subtracts $50 from the monthly amount, and the payment is never less than $10 a month. If your AGI is $10,000 or less, the payment is $10 a month. If you leave standard payment blank, Multicalify estimates a 10-year EMI from balance and rate.
Monthly RAP payment = (Tier % × AGI) ÷ 12 − ($50 × dependents), minimum $10
The tiers follow the official rule in 34 CFR 685.209. Confirm current tables and interest rules on StudentAid.gov, because policy details can change.
Worked example
Suppose AGI is $85,000, family size is 1, dependents is 1, balance is $45,000, and rate is 6.5%. AGI of $85,000 falls in the $80,001 – $90,000 tier, which is 8%. Monthly before dependents is $85,000 × 0.08 ÷ 12 ≈ $566.67. After the $50 dependent reduction, RAP is about $516.67. A standard 10-year EMI on the same balance and rate is roughly $511, so RAP is about the same as the standard payment under these inputs, and the RAP interest and matching principal rules are the main difference.
| Item | Value |
|---|---|
| AGI / family size / dependents | $85,000 / 1 / 1 |
| Tier percent (AGI $80,001 – $90,000) | 8% |
| Before dependents | About $566.67 / month |
| RAP after $50 reduction | About $516.67 / month |
| Standard 10-yr EMI (approx) | About $511 / month |
RAP income tiers (official table)
RAP uses your total AGI (combined AGI if married filing jointly), not income above a poverty line. Find your tier, take that percent of AGI, divide by 12, then subtract $50 per dependent. The payment is never less than $10 a month.
| AGI | Yearly base payment |
|---|---|
| $10,000 or less | $120 a year ($10/month) |
| $10,001 – $20,000 | 1% |
| $20,001 – $30,000 | 2% |
| $30,001 – $40,000 | 3% |
| $40,001 – $50,000 | 4% |
| $50,001 – $60,000 | 5% |
| $60,001 – $70,000 | 6% |
| $70,001 – $80,000 | 7% |
| $80,001 – $90,000 | 8% |
| $90,001 – $100,000 | 9% |
| Over $100,000 | 10% |
Example: AGI $55,000, 2 dependents. 5% × $55,000 = $2,750 a year, ÷ 12 = $229.17, minus $100 = $129.17 a month.
Under RAP, unpaid monthly interest is not charged if you pay on time, and if your payment cuts principal by less than $50, the Department adds a matching principal reduction (up to $50). Any balance left after 360 qualifying payments (30 years) is forgiven.
How to interpret RAP versus standard
A lower RAP payment can improve cash flow, but it does not automatically minimize total interest. Compare RAP with the standard EMI and the monthly interest on the balance. If RAP sits below accruing interest, expect balance growth unless subsidies or forgiveness rules apply in your real program.
When paycheck withholding changes AGI expectations, refine income with the salary and tax calculator. For generic amortizing math without IDR tiers, use the EMI calculator or loan calculator.
RAP vs IBR at a glance
| RAP | IBR | |
|---|---|---|
| Payment based on | 1%–10% of total AGI, minus $50 per dependent | 15% of discretionary income (10% for new borrowers) |
| Discretionary income | Not used | AGI above 150% of the federal poverty guideline |
| Minimum payment | $10 a month | Can be $0 |
| Payment cap | None | Never more than the 10-year standard payment |
| Forgiveness | After 30 years (360 payments) | After 25 years (20 for new borrowers) |
| Unpaid interest | Not charged if you pay on time | Not charged on subsidized loans for the first 3 years only |
| Loans eligible | Most Direct Loans, made before or after July 1, 2026; not parent PLUS | Direct Loans made before July 1, 2026, and FFEL loans |
Rule of thumb: lower incomes with dependents often pay less on RAP; borrowers who want 20–25 year forgiveness or a capped payment may prefer IBR if they still qualify. Check your real numbers in the Loan Simulator on StudentAid.gov.
Inputs that move RAP most
- Total AGI, which sets the tier percent
- Whether AGI crosses a $10,000 tier boundary
- Dependent count and the per-dependent reduction
- Loan balance and rate used for the standard comparison
- Whether you override or auto-calculate the 10-year payment
Practical repayment tips
Run a low-income year and a promotion year side by side in the repayment assistance plan calculator. If the RAP estimate jumps sharply, plan for payment shock before AGI rises. Keep documentation for family size and dependents consistent with what a servicer would expect.
The repayment assistance plan calculator is a planning aid. Treat StudentAid.gov and your servicer as the source of truth for enrollment, certification, and forgiveness clocks. This Multicalify page is a planning sketch so you can ask better questions, not a substitute for official calculators.
Common mistakes
- Treating an approximate RAP estimate as a locked servicer bill
- Using gross wages instead of AGI without adjusting
- Ignoring the standard 10-year comparison and unpaid interest
- Forgetting dependent reductions or counting dependents inconsistently
- Assuming forgiveness rules without reading current federal guidance
- Skipping AGI sensitivity when income is variable
Worked RAP payment sketch
RAP estimates start from total AGI and the tier table, then subtract $50 per dependent with a $10 monthly minimum. Treat the payment as a sketch. Official servicer tools and current rules override any educational model when you enroll.
Limitations and planning note
This repayment assistance plan calculator is an educational approximation of RAP style payments. It is not financial advice, not an official Department of Education tool, and not a promise of forgiveness. Confirm formulas, eligibility, and interest treatment on StudentAid.gov before you enroll or refinance.

Why the RAP payment has a $10 floor
If your AGI is $10,000 or less, the RAP payment is $10 a month ($120 a year). Dependents can also reduce a small payment, but the result never drops below $10 a month. That floor is a feature of the official rule, and it is why low-income borrowers still make a small payment.
Even with a $10 payment, review interest accrual and program rules. A small payment does not mean the loan disappears.
Building a yearly certification habit
Income-driven plans usually need periodic income updates. Recalculate RAP when you change jobs, add dependents, or file a very different return. Save each Multicalify run with the AGI and family size you used so you can explain changes to yourself later.
If you are choosing between RAP and staying on a standard 10-year path, quantify the monthly gap and the interest risk explicitly. Cash-flow relief and total cost are different goals.
Variable income and estimated AGI
Freelancers and commission earners should model a quiet year and a strong year. If RAP is affordable only in the quiet year, build a reserve for the strong-year payment before income rises. Using last year AGI blindly can surprise you when certification catches up.
When tax withholding and AGI diverge, reconcile with the salary and tax calculator before you trust a single RAP run. Better AGI inputs beat prettier payment screenshots.
Interest awareness without panic
Compare the RAP estimate with monthly interest on the balance. If RAP is below interest, note that gap as a planning risk rather than assuming the loan shrinks every month. Official subsidy or forgiveness rules may change the story, which is another reason to confirm details on StudentAid.gov.
Keep the standard EMI on the same sheet so you can see what full amortization would cost if cash flow improves later.
Conclusion
Use this repayment assistance plan calculator to estimate a tiered payment based on total AGI, apply dependent reductions, and compare against a standard 10-year EMI. Stress-test AGI, confirm official rules on StudentAid.gov, and revisit the estimate whenever income or household size changes.
