Quick overview
Income-driven repayment (IDR) plans let borrowers with federal student loans base monthly payments on income and family size instead of loan balance. That typically lowers monthly cash flow compared with standard repayment and creates a pathway to loan forgiveness after 20–25 years of qualifying payments (varies by plan). IDR plans can also change how interest accrues and may include limited government interest subsidies under certain plans (Federal Student Aid).
Note: This article explains the rules and trade-offs for REPAYE, PAYE, IBR and ICR as of 2025; always verify details at the official Federal Student Aid site (https://studentaid.gov) or with your loan servicer. This is educational content and not individualized legal, tax, or financial advice.
Why IDR matters
For many borrowers, IDR plans are the only realistic way to make monthly payments affordable during early career years, after career interruptions or during graduate school. In my practice advising clients with student debt, switching to the correct IDR plan often prevented delinquency and preserved credit while freeing cash to build emergency savings.
How payments are calculated (in plain language)
IDR plans generally use your Adjusted Gross Income (AGI) from your federal tax return and your household size to compute “discretionary income.” Monthly payment is then a percentage of that discretionary income divided by 12. Key points:
- Discretionary income definition: most plans use a formula tied to poverty guidelines (see studentaid.gov for current thresholds).
- Payment percentages: range from 10% to 20% depending on plan (see plan table below).
- Recertification: you must recertify income and family size every 12 months to keep payments based on current income.
For step-by-step calculators, use the official estimator at Federal Student Aid (https://studentaid.gov) or educational calculators from the Consumer Financial Protection Bureau (https://www.consumerfinance.gov).
Side-by-side: The four main IDR plans
| Plan | Monthly payment | Typical forgiveness timeline | Loan eligibility (high level) |
|---|---|---|---|
| REPAYE (Revised PAYE) | 10% of discretionary income | 20 years (undergrad-only loans) or 25 years (includes grad loans) | Direct Loans only |
| PAYE (Pay As You Earn) | 10% of discretionary income (capped at standard repayment amount) | 20 years for qualifying borrowers | Direct Loans; available to newer borrowers who meet original PAYE rules |
| IBR (Income-Based Repayment) | 10% or 15% of discretionary income, depending on loan date | 20 years (if new borrower after July 1, 2014) or 25 years otherwise | Direct Loans and some FFEL loans (with consolidation) |
| ICR (Income-Contingent Repayment) | Lesser of 20% of discretionary income or a fixed 12-year repayment amount adjusted for income | 25 years | Direct Loans and some FFEL loans (with consolidation) |
(For current eligibility rules and exact formulas see Federal Student Aid: https://studentaid.gov.)
Common differences that matter when choosing a plan
- Payment size and generosity
- REPAYE and PAYE are usually the most generous for lower-income borrowers because they set payments at 10% of discretionary income.
- IBR will be 10% or 15% depending on borrower status (borrowers with older loans may face 15%).
- ICR is typically the least generous, with 20% of discretionary income or the 12-year adjusted schedule.
- Interest subsidy and unpaid interest
- REPAYE includes a partial interest subsidy that can reduce how fast interest capitalizes when payments don’t fully cover interest (see studentaid.gov for the mechanics). That matters for long-term cost.
- Forgiveness timing
- PAYE and IBR (for new borrowers) often forgive after 20 years, while ICR generally requires 25 years.
- REPAYE forgiveness varies 20–25 years depending on undergraduate vs graduate loan composition.
- Loan types accepted
- Some older FFEL (Federal Family Education Loan) or Perkins loans aren’t directly eligible for certain plans unless you consolidate to a Direct Consolidation Loan first. Consolidation can change eligibility and reset certain timelines — coordinate with a counselor or your servicer before consolidating.
Practical examples (rounded for clarity)
Example 1 — Early-career borrower
- AGI: $35,000; household size: 1; discretionary income calculation yields monthly payment under REPAYE or PAYE near $70–$90. Under ICR or IBR (if 15%), the payment could be higher.
Example 2 — Borrower with grad school debt
- AGI: $60,000; large grad debt balance: REPAYE may reduce the monthly payment to a manageable level (10% of discretionary income) but could extend forgiveness to 25 years; weigh that against paying more now to reduce total interest.
These examples are illustrative — use the official loan simulator to run your exact numbers (https://studentaid.gov).
Important administrative rules and tax considerations
- Annual recertification: You must recertify income and household size every 12 months. If you miss recertification, your servicer may place you on an alternative payment amount and interest may capitalize.
- Loan consolidation: Consolidating loans can change eligibility and forgiveness timelines. Consolidation can be useful if you have FFEL loans and need Direct Loan eligibility, but consolidation restarts the clock on qualifying payments for forgiveness in many cases.
- Tax treatment of forgiveness: Under the American Rescue Plan Act, federal student loan forgiveness amounts were excluded from federal taxable income through December 31, 2025. State tax treatment can vary — check IRS guidance (irs.gov) and your state tax agency. This is evolving policy; verify at the time of forgiveness.

Who should consider each plan?
- REPAYE: Good for lower- and middle-income borrowers, including those with significant graduate debt, because of the 10% payment rate and interest subsidy; expect longer forgiveness during grad-level borrowing.
- PAYE: Best for borrowers who qualify under PAYE’s eligibility rules (newer borrowers who meet PAYE’s original conditions) and want a 10% payment cap with a 20-year forgiveness path.
- IBR: Useful for borrowers with older loans or those with FFEL loans who can’t access PAYE or REPAYE without consolidation; may be 15% for older borrowers.
- ICR: Considered when other plans aren’t available (e.g., some FFEL borrowers who don’t consolidate). It’s also the plan used for Income-Contingent repayment calculations for Parent PLUS loans after consolidation.
Working through trade-offs: a short decision checklist
- Do you need maximum short-term payment relief? If yes, look at REPAYE or PAYE.
- Do you have FFEL loans or Parent PLUS loans? Check IBR/ICR or consider consolidation to enter a Direct Loan-based IDR plan (careful — consolidation affects timelines).
- Are you planning to pursue Public Service Loan Forgiveness (PSLF)? Only payments made under qualifying repayment plans while working full-time for a qualifying employer count — confirm which IDR payments your servicer will certify for PSLF (see studentaid.gov/pslf).
- How comfortable are you with potentially paying more interest over a longer timeline? Using IDR can increase total interest paid; compare with refinancing to a private lender if you have stable income and want lower total interest but no federal protections.

Common mistakes I see in practice
- Assuming all federal loans qualify for the same IDR plans. Loan type matters (Direct vs FFEL vs Perkins).
- Consolidating too early without understanding that consolidation can restart forgiveness timelines.
- Forgetting annual recertification, which can trigger higher payments and interest capitalization.
- Overlooking PSLF certification steps when working in public service — annual employer certification is crucial.
Final thoughts
Choosing an IDR plan is both technical and personal: small differences in income, family size, loan mix, and career plans (including public service) change which plan is best. Start with the official calculators, gather your loan documents, and contact your servicer to confirm eligibility. If your situation is complex — multiple loan types, planned consolidation, or public service intentions — consider consulting a student-loan-savvy financial advisor or nonprofit counselor.
