📐 2026 IBR Calculation Example

Example: Single borrower, $60,000 AGI, family size 1, contiguous US.

Poverty Guideline: $15,060 × 150% = $22,590

Discretionary Income: $60,000 - $22,590 = $37,410

New IBR (10%): $37,410 × 0.10 = $3,741/year = $311.75/month

Payment Cap: Compare to Standard 10-year payment ($40,000 at 5.8% = $440/month) → capped at $311.75

Forgiveness: 20 years = $74,820 total paid, remaining balance forgiven (may be taxable)

All calculations use 2026 HHS poverty guidelines and Department of Education formulas

❓ Frequently Asked Questions About IBR Payments

How much will my IBR payment be in 2026?

Your IBR payment is 10% or 15% of discretionary income (AGI minus 150% of poverty guideline). For example: $60,000 income, family of 1 = $12,180 discretionary income × 10% = $1,218/year = $101.50/month. Use our calculator above for your exact amount.

What is the formula for calculating IBR payments?

IBR payment formula: Discretionary Income = AGI - (Poverty Guideline × 150%). Monthly payment = Discretionary Income × (10% or 15%) ÷ 12. For New IBR: 10%, 20-year forgiveness. Old IBR: 15%, 25-year forgiveness. Our calculator uses 2026 poverty guidelines.

How long does it take to get loan forgiveness under IBR?

Under New IBR (borrowers after July 1, 2014): 20 years of qualifying payments. Under Old IBR (borrowers before July 1, 2014): 25 years. PAYE: 20 years. REPAYE: 20 years (undergrad) or 25 years (graduate). Forgiveness amount may be taxable.

How does marriage affect my IBR payments?

If married filing jointly: spouse's income and loans are included. If married filing separately: only your income is considered (except REPAYE includes spouse income regardless). For IBR/PAYE, filing separately can lower payments but may cost more in taxes. Our calculator accounts for all scenarios.

What's the difference between IBR, PAYE and REPAYE?

IBR: 10% (new) or 15% (old) of income, payment capped at standard plan, 20-25 years. PAYE: 10% of income, payment capped, 20 years, requires new borrower status. REPAYE: 10% of income, no payment cap, 20-25 years, includes spouse income always. Use our plan selector above to compare.

Is student loan forgiveness under IBR taxable?

Through 2025, forgiven amounts are tax-free under the American Rescue Plan Act. However, this provision expires after 2025. Starting 2026, forgiven amounts may be taxable as ordinary income. Consult a tax professional. Our calculator shows potential forgiveness amounts.

How often do I need to recertify my IBR plan?

You must recertify your income and family size annually. Failure to recertify can result in payment increases (up to standard plan amount) and interest capitalization. Recertification deadlines are typically 30-60 days before your anniversary date. Our calculator helps plan for changes.

Can I switch from IBR to another repayment plan?

Yes, you can switch between income-driven plans anytime. Switching may reset forgiveness timeline if you change plan types. Some borrowers switch to maximize benefits (e.g., IBR to PAYE for lower payments). Our calculator helps compare options before switching.
