IBR payment estimate
Income-Based Repayment Calculator
Estimate your student loan IBR payment, see how income and household size affect the result, and compare Income-Based Repayment with RAP, PAYE, and ICR.
Calculator assumptions and limits
These tools provide planning estimates only. Your loan servicer and StudentAid.gov determine your final eligibility, payment amount, due date, and forgiveness credit.
Show calculation assumptions
- IBR estimates use AGI, household size, and legacy discretionary-income formulas where applicable.
- The comparison also shows other income-driven repayment plans so you can see when IBR is not the lowest estimate.
- Your servicer and StudentAid.gov determine final IBR eligibility, payment amount, and recertification deadlines.

Estimate your IBR payment by income
An IBR repayment calculator is most useful when you test more than one income scenario. These examples are illustrative only; the official IDR application uses verified income, family size, loan type, and borrower history.
Test whether the poverty-guideline allowance makes IBR materially lower than a fixed payment.
Add dependents and compare IBR discretionary income with RAP's AGI tier.
Check IBR payment caps, PAYE eligibility, PSLF, and total cost before switching.

How to read your IBR payment estimate
IBR estimates are most useful when you compare them against at least two alternatives. If IBR is lower than RAP, check whether you qualify and whether the forgiveness timeline fits your plan. If RAP or PAYE is lower, look at eligibility, payment caps, PSLF, and long-term cost before switching.
Does the IBR calculation use AGI with capital gains?
IBR planning estimates usually begin with AGI, and AGI can include capital gains or other one-time income from the tax year. If your tax return does not reflect current income, check whether the official IDR application lets you document current income instead of relying only on the prior return.
When an IBR Calculator Is Useful
Use an Income-Based Repayment calculator when your goal is to understand whether a legacy IDR plan could lower your student loan payment. IBR is often worth checking when your income is low relative to family size, PAYE eligibility is uncertain, or you need to compare spouse-income treatment.
Income fit
IBR uses discretionary income, so household size and poverty-guideline allowances matter.
Plan comparison
IBR should be compared with RAP, PAYE, ICR, and standard repayment before switching.
PSLF strategy
Public service borrowers should focus on qualifying payments, not only the lowest estimate.
IBR vs Other IDR Plans
| Plan | Why compare it with IBR? | Common next check |
|---|---|---|
| RAP | Uses AGI tiers and dependent reductions instead of the legacy discretionary-income formula. | IBR vs RAP |
| PAYE | May have a shorter forgiveness path for eligible borrowers. | Check borrower-history eligibility. |
| ICR | Often relevant for Parent PLUS borrowers after consolidation. | Parent PLUS checker |
Frequently Asked Questions
What is the Income-Based Repayment calculator for?
This Income-Based Repayment calculator helps federal student loan borrowers estimate how IBR may compare with RAP, PAYE, and ICR. Use it when you want an income-based payment estimate before checking your official options through StudentAid.gov or your loan servicer.
Is IBR the same as IDR?
No. IDR means income-driven repayment, the broader category of federal repayment plans tied to income. IBR, or Income-Based Repayment, is one plan within that category. Other income-driven options can include PAYE, ICR, and RAP, depending on eligibility and policy timing.
Can IBR payments be zero dollars?
IBR can produce a very low or zero monthly payment when discretionary income is low. Your actual bill depends on your adjusted gross income, family size, poverty-guideline allowance, loan type, borrower history, and annual income recertification through the official IDR process.
Should married borrowers use this IBR calculator?
Yes, but treat the result as a planning estimate. Married filing status can change which income is counted under some legacy IDR plans. Compare the repayment effect with tax consequences before changing filing status, and confirm final treatment through official channels.
Does IBR use AGI that includes capital gains?
IBR estimates usually start with adjusted gross income from tax information. Capital gains can be part of AGI, so borrowers with unusual tax-year income should compare tax-return income with any allowed current-income documentation through the official IDR process.
