📌 Quick Answer: IBR payment = (10% or 15% of discretionary income) ÷ 12. Discretionary income = AGI − 150% of the poverty guideline for your family size [citation:5][citation:7]. For a single borrower earning $45,000 in 2026: protected income = $23,940, discretionary = $21,060, and payment = $175.50/month (10% rule). If your calculated payment exceeds your 10-year Standard payment, the Standard amount caps it [citation:15].

What is an IBR Payment Calculator and How Does It Work?
An IBR payment calculator estimates your monthly payment under the Income-Based Repayment plan. Our IBR payment calculator 2026 uses the official formula: (10% or 15% of discretionary income) ÷ 12, where discretionary income is your AGI minus 150% of the federal poverty guideline for your family size [citation:5][citation:7]. The calculator answers the key question: "What will my IBR payment be?"
How does the Income-Based Repayment calculator work? Enter your AGI, family size, state, and loan disbursement date. The calculator instantly shows your estimated monthly payment, discretionary income, protected income, payment percentage, payment cap, and forgiveness timeline.
IBR Payment Formula (2026)
Step 1: Protected Income = 150% of the poverty guideline for your family size and state [citation:7].
Step 2: Discretionary Income = AGI − Protected Income. If negative, use $0.
Step 3: Annual IBR = Discretionary Income × 10% (or 15% for pre-2014 loans) [citation:5].
Step 4: Monthly IBR = Annual IBR ÷ 12.
Step 5: Cap = Your 10-year Standard Repayment amount. If calculated IBR > cap, use cap [citation:15].
IBR Eligibility and Loan Types
Qualifying loans: Direct Subsidized, Direct Unsubsidized, Direct Grad PLUS, and Direct Consolidation Loans. FFEL loans must be consolidated into a Direct Consolidation Loan [citation:5].
2026 eligibility change: Borrowers with any federal loans disbursed on or after July 1, 2026 are not eligible for IBR and will only have access to the new RAP plan [citation:4][citation:5].
Parent PLUS borrowers: Must consolidate into a Direct Consolidation Loan before June 30, 2026 to access IBR [citation:4].
IBR vs Standard Repayment Cap
IBR includes a critical protection: your payment is capped at what you would pay under the 10-year Standard Repayment Plan [citation:15]. If your calculated IBR payment is higher than the Standard payment, the Standard amount becomes your payment. This prevents high-income borrowers from paying more under IBR than they would under a standard plan.
Interest and Forgiveness
Interest: Unpaid interest is capitalized (added to principal) if you leave IBR or no longer qualify [citation:5]. The government may pay up to $50 toward principal if your payment doesn't reduce it by that much [citation:7].
Forgiveness: 20 years for borrowers whose first loan was on or after July 1, 2014. 25 years for borrowers whose first loan was before that date [citation:15]. Forgiven balances may be taxable as income.
❓ Frequently Asked Questions
How is the IBR monthly payment calculated?
IBR payment = (10% or 15% of discretionary income) ÷ 12. Discretionary income = AGI − 150% of the federal poverty guideline for your family size. Loans disbursed before July 1, 2014 use 15%; loans on or after use 10% [citation:5].
What is the 150% poverty guideline for 2026?
For the 48 contiguous states and D.C. in 2026: 1 person = $23,940/year ($1,995/month); 2 = $32,460; 3 = $40,980; 4 = $49,500. Alaska and Hawaii have higher guidelines [citation:8].

Is my IBR payment capped?
Yes. Your IBR payment will never exceed what you would pay under the 10-year Standard Repayment Plan. This cap protects high-income borrowers [citation:15].
Do I qualify for IBR in 2026?
You must have a qualifying federal loan (Direct, FFEL, or consolidated) and your calculated IBR payment must be less than your 10-year Standard payment. Borrowers with loans disbursed after July 1, 2026 are not eligible for IBR [citation:4].

💡 Expert Tips for IBR Borrowers
Tip #1: File taxes separately if married to exclude spousal income from the IBR calculation — but run the numbers both ways to compare the tax impact [citation:7].
Tip #2: Recertify your income every year. Missing the deadline can increase your payment to the Standard amount [citation:6].
Tip #3: If your income drops, request a recalculation immediately — your payment can be lowered mid-year [citation:6].
Tip #4: $0 payments count toward forgiveness. Don't assume you're ineligible just because you can't afford a payment [citation:6].
