What This Calculator Does
This student loan income-driven repayment (IDR) estimator calculates your estimated monthly payment and forgiveness timeline under the available federal IDR plans: IBR (Income-Based Repayment), PAYE (Pay As You Earn), and ICR (Income-Contingent Repayment). It uses your adjusted gross income, family size, and the 2026 federal poverty guidelines to determine discretionary income and calculate payments. Note that the SAVE plan was struck down by federal courts in 2024, and affected borrowers were transitioned to IBR or other available IDR plans.
The Formula
Income-driven repayment plans base your monthly payment on discretionary income, which is the difference between your adjusted gross income (AGI) and 150% of the federal poverty guideline for your family size and state (100% for ICR). The payment percentage varies by plan: 5% for undergraduate IBR (new borrowers), 10% for PAYE, 15% for old IBR, and 20% for ICR. Remaining balances are forgiven after 20 or 25 years of qualifying payments depending on the plan.
Step-by-Step Example
Enter loan details
$35,000 total student loan balance at 6.53% interest rate. Undergraduate loans.
Enter income information
AGI: $45,000. Family size: 1. 2026 poverty guideline for 1 person: $15,650. 150% threshold: $23,475.
Calculate discretionary income
$45,000 - $23,475 = $21,525 discretionary income.
Calculate IBR payment
New borrower IBR for undergrad: 5% of discretionary. $21,525 x 5% / 12 = $90/month. Standard 10-year payment would be $398/month. Savings: $308/month.
Real-World Use Cases
Plan Comparison
Compare monthly payments across all available IDR plans to find the option with the lowest payment or total cost depending on your financial goals.
PSLF Strategy Planning
Public Service Loan Forgiveness requires 10 years of IDR payments while working for a qualifying employer. Calculate your total cost under PSLF versus standard repayment.
Post-Graduation Budgeting
Estimate your student loan payment before graduating to plan your post-college budget and determine what salary you need to manage payments comfortably.
Common Mistakes to Avoid
Not recertifying income annually. IDR plans require annual income recertification. Missing the deadline can cause your payment to jump to the standard amount.
Forgetting that forgiven balances may be taxable. Under current law, IDR forgiveness after 20-25 years may be treated as taxable income (PSLF forgiveness is tax-free).
Assuming the SAVE plan is still available. The SAVE plan was struck down by federal courts in 2024. Borrowers should evaluate IBR, PAYE, or ICR as alternatives.
Not considering total interest paid over the life of the plan. Lower monthly payments mean more interest accrues. A $35,000 loan on a 20-year IDR plan may cost significantly more in total interest than a 10-year standard plan.
Ignoring PSLF eligibility. If you work for a government or nonprofit employer, PSLF forgiveness after 10 years (tax-free) is far more valuable than 20-25 year IDR forgiveness.

IDR payment estimates are based on simplified calculations using 2026 federal poverty guidelines. Actual payments may differ based on your specific loan servicer calculations, tax filing status, and income documentation. The SAVE plan status reflects federal court rulings as of early 2025.
