What is an ICR Calculator and How Does It Work?
An ICR calculator is an essential tool for federal student loan borrowers considering Income-Contingent Repayment. Our ICR calculator 2026 uses official Department of Education formulas to answer "how much will I pay under ICR?" The income contingent repayment calculator provides monthly payment estimates, forgiveness projections, and tax implications. Whether you're a Parent PLUS borrower or have Direct Loans, this student loan icr calculator helps you plan your repayment strategy.
How does the income-driven repayment calculator work? Enter your loan balance, interest rate, AGI, family size, state, and loan type. The icr payment calculator instantly shows your monthly payment, annual payment, discretionary income, total interest, forgiveness amount, and estimated tax bomb. The icr plan calculator also applies the special Parent PLUS rule automatically.
ICR Payment Formula
Step 1: Find poverty guideline for your family size and state. Contiguous US: family 1 = $15,060, family 2 = $20,200, family 3 = $25,340.
Step 2: Calculate 150% of poverty guideline.
Step 3: Subtract from AGI to get discretionary income.
Step 4: Multiply by 20% for annual payment.
Step 5: Divide by 12 for monthly payment.
Parent PLUS special rule: Payment = lesser of ICR formula OR 12-year standard repayment amount.
ICR vs Other Income-Driven Plans (2026)
ICR: 20% of discretionary income, 150% poverty exemption, 25-year forgiveness, no interest subsidy. Best for Parent PLUS borrowers.
SAVE: 5-10% of discretionary income, 225% poverty exemption, full interest subsidy. Best for most borrowers (lowest payments).
IBR: 10-15% of discretionary income, 150% poverty exemption. For borrowers before 2014.
PAYE: 10% of discretionary income, 150% poverty exemption. For newer borrowers.
Parent PLUS Loans and ICR
Parent PLUS loans must be consolidated into a Direct Consolidation Loan to become eligible for ICR. After consolidation, payment is the lesser of: (1) 20% of discretionary income, OR (2) 12-year standard repayment amount. The "double consolidation loophole" may allow access to SAVE or PAYE.
The Tax Bomb
Forgiven amounts under ICR become taxable as ordinary income starting 2026. Estimated tax = forgiven amount × your tax bracket. For $50,000 forgiven at 24% bracket = $12,000 tax bill. PSLF forgiveness is tax-free.
