Income Driven Repayment Student Loans Explained

Short answer: Income driven repayment, known as IDR, is a set of federal repayment plans that set your monthly student loan payment from your income and family size, instead of from your loan balance alone. Your payment is a percentage of your discretionary income, which is your income minus a protected amount based on the federal poverty guideline for your family size. After 20 or 25 years of qualifying payments, depending on the plan, any balance that remains may be forgiven. The plans are changing in 2025 and 2026, so check the current plan names and rules at studentaid.gov before you apply.

A fixed student loan payment can feel impossible when income is low, irregular, or just starting out. A payment set by the loan balance does not care whether you lost hours at work, changed jobs, or had a child. Income driven repayment was built for that gap. It links the payment to what you earn, so the payment falls when income falls and rises when income rises. This guide explains how IDR works, how to estimate your payment, which plans are open now, and what to watch out for.

What income driven repayment is

IDR is not one plan. It is a family of federal repayment plans for Direct Loans, and for some older loans after consolidation. Each plan uses your income and family size to set a monthly payment, caps it at a percentage of discretionary income, and has a forgiveness period. Discretionary income is your adjusted gross income, known as AGI, minus a protected amount based on the federal poverty guideline for your family size. For most older plans, the protected amount is 150 percent of the guideline. For Income Contingent Repayment, known as ICR, it is 100 percent. If your discretionary income is zero or below zero, your monthly payment can be $0. A $0 payment still counts as a qualifying payment for forgiveness, if you are enrolled, meet the other rules, and recertify your income each year.

The older plans, and what is changing

The main older plans were Income Based Repayment (IBR), Pay As You Earn (PAYE), Income Contingent Repayment (ICR), and Saving on a Valuable Education (SAVE). IBR is the oldest and most widely used plan. For new borrowers, who first borrowed on or after July 1, 2014, IBR is generally 10 percent of discretionary income, with forgiveness after 20 years. For older borrowers, it is generally 15 percent, with forgiveness after 25 years. IBR is the only IDR plan that accepts FFEL loans in their original form, and it remains the main option for many borrowers. PAYE is generally 10 percent of discretionary income, with forgiveness after 20 years, but it has stricter eligibility rules. It is being phased out, with new enrollments closing by July 1, 2027, and the plan ending by July 1, 2028. ICR is generally the lower of 20 percent of discretionary income or a fixed 12 year payment, with forgiveness after 25 years, and it is being phased out on the same dates. SAVE offered the lowest payments for many borrowers, but it was blocked by court action and has now been ended. No new borrowers are enrolled in SAVE. Do not plan around SAVE.

The new plan: Repayment Assistance Plan

The One Big Beautiful Bill Act, signed on July 4, 2025, created a new plan called the Repayment Assistance Plan, known as RAP. RAP is set to start for loans disbursed on or after July 1, 2026, and it is expected to become the only IDR option for all borrowers by July 1, 2028. Details are still being set out in regulations, so treat any RAP figure as provisional until you see it on the official studentaid.gov page. In broad terms, RAP sets payments at 1 to 10 percent of adjusted gross income, depending on income. It also includes a minimum monthly payment, reported as $10 a month in draft regulations, and a forgiveness period reported as 30 years. Check the current studentaid.gov page for the final figures. RAP will matter most to borrowers who take out new loans on or after July 1, 2026. Borrowers with older loans should focus first on IBR.

How to estimate your income driven repayment

You need four facts: your adjusted gross income, your family size, the poverty guideline for that family size, and the percentage for your plan. First, find your adjusted gross income, the income figure on your most recent federal tax return. If your income has changed a lot since that return, you can usually provide other proof, such as pay stubs. Second, work out discretionary income. For IBR and PAYE, subtract 150 percent of the poverty guideline for your family size from your adjusted gross income. For ICR, subtract 100 percent. The guideline is published each year and rises with family size. Do not use a poverty figure from an old article. Use the loan simulator at studentaid.gov, which applies the current figure. Third, apply your plan percentage: 10 percent for new borrower IBR and PAYE, 15 percent for older borrower IBR, and 20 percent for ICR, or the fixed 12 year payment if that is lower. Divide the yearly result by 12 for your monthly payment. Fourth, compare it with your standard payment. Under IDR, your payment is generally capped at the standard 10 year amount.

Worked example: how the payment is calculated

This is an illustration with round numbers. The numbers are not a real payment, and they are not a promise of what you will pay. Suppose a single borrower with no dependents has an adjusted gross income of $48,000 a year, and the protected amount in this illustration is $24,000 a year, a rounded figure used only to show the math. Discretionary income is $48,000 minus $24,000, which is $24,000 a year. Under new borrower IBR, at 10 percent, the yearly payment is $2,400, or $200 a month. Under older borrower IBR, at 15 percent, it is $3,600 a year, or $300 a month. Under ICR, at 20 percent, it is $4,800 a year, or $400 a month, unless the fixed 12 year payment is lower. Now suppose the same borrower has a family of four, and the protected amount in this illustration is $48,000 a year. Discretionary income is $0, so the IBR payment is $0 a month, and that $0 payment can still count toward forgiveness if the borrower recertifies each year. Compare that with a standard payment. On a $30,000 loan at 6 percent in this illustration, over 10 years, a rough standard payment would be about $333 a month before interest is fully counted. The IBR payment of $200 a month is lower, so IDR would ease the monthly cost, but the borrower would pay for 20 years instead of 10, and more interest could build up.

Who can use income driven repayment

IDR is for federal Direct Loans, including Direct Subsidized Loans, Direct Unsubsidized Loans, Direct PLUS Loans made to graduate or professional students, and Direct Consolidation Loans, subject to each plan’s rules. FFEL loans in their original form are eligible only for IBR. Perkins Loans are not eligible in their original form, but they can become eligible if consolidated into a Direct Consolidation Loan. Private student loans are never eligible for federal IDR. Parent PLUS loans have special rules. A Direct Parent PLUS Loan in its original form is not eligible for most IDR plans, and a consolidation loan that includes a Parent PLUS Loan and is disbursed on or after July 1, 2026, may not be eligible for any IDR plan. Parents with PLUS loans should check the current rules at studentaid.gov and talk to their servicer before consolidating. Tax filing status also matters. Under IBR, PAYE, and ICR, if you are married and file taxes separately, your spouse income is generally not counted. Filing separately can lower an IDR payment, but it can also raise your taxes, so do not change your filing status for IDR alone without checking the tax effect.

The dates that matter in 2026

Three dates matter for IDR borrowers in 2026. The first is June 30, 2026. Sources linked from studentaid.gov state that a Direct Consolidation Loan that includes FFEL, Perkins, or Parent PLUS loans must be disbursed by June 30, 2026, to keep access to the older IDR plans, PSLF, or IDR forgiveness. A loan disbursed on or after July 1, 2026, will have more limited options, so apply well before that date, because processing takes time. The second date is July 1, 2026. That is when RAP starts for new loans, and when the older IDR plans stop being available for new loans. If all of your loans were taken out before July 1, 2026, you can still enroll in the older plans, subject to their own closing dates. The third date is July 1, 2027, for PAYE and ICR enrollment, and July 1, 2028, for the end of those plans. After that date, IBR and RAP are expected to be the remaining IDR options. These dates are in transition, so check the IDR page at studentaid.gov on the day you apply, and confirm any date with your servicer.

Forgiveness, interest, and tax: what to expect

Forgiveness under IDR is not automatic, and it is not quick. You must make the required number of qualifying monthly payments, generally 240 payments for 20 years or 300 payments for 25 years, depending on the plan, and you must recertify your income each year. If you miss recertification, your payment can rise, and your progress can be affected. Keep a record of every payment, and check your payment count with your servicer each year. Interest can also surprise borrowers. If your IDR payment is lower than the interest that builds up each month, your balance can grow even while you pay on time. That is called negative amortization. Under IBR, the government pays the unpaid interest on subsidized loans for the first three years, but after that, unpaid interest can build up. A balance forgiven under IDR may be treated as taxable income in the year it is forgiven, depending on the tax law in force at that time. Do not assume it will be tax free. Check the current tax rules when forgiveness is near, and talk to a tax professional if the amount is large.

Actionable steps: how to apply and stay on track

1. List every federal loan you hold, with its type, balance, rate, and servicer, from your account at studentaid.gov. Mark each loan Direct, FFEL, Perkins, or private.
2. Use the loan simulator at studentaid.gov to estimate your payment under IBR, PAYE, and ICR, using your real income, family size, and tax filing status.
3. Compare the IDR payment with your standard payment, and with what you can afford each month. Note the total over the full term, not just the monthly amount.
4. If you hold FFEL or Perkins loans and want a plan other than IBR, check the consolidation rules and the June 30, 2026 disbursement date at studentaid.gov.
5. Apply for IDR at studentaid.gov, using your FSA ID. You will need your income information.
6. Set a yearly reminder to recertify your income. Missing recertification can raise your payment.
7. Check your payment count each year with your servicer.

FAQ

How do I estimate my income driven repayment?

Use the loan simulator at studentaid.gov. Enter your loan balances, interest rates, income, family size, and tax filing status, and it will show your estimated payment under each plan you are eligible for. You can also estimate by hand: subtract 150 percent of the poverty guideline for your family size from your adjusted gross income, multiply by 10 percent for a new borrower or 15 percent for an older borrower under IBR, and divide by 12. The simulator is more reliable, because it uses the current guideline and your real figures.

Which income driven repayment plan has the lowest payment?

It depends on your income, family size, loan type, and when you borrowed. SAVE had the lowest payments for many borrowers, but SAVE has been ended. Among the plans that remain, PAYE and new borrower IBR generally give the lowest payments, at 10 percent of discretionary income, while older borrower IBR is 15 percent and ICR is 20 percent or a fixed 12 year payment, whichever is lower. Use the loan simulator to compare the plans on your own figures.

Can my income driven payment be $0?

Yes. If your discretionary income is zero or below zero, your monthly payment can be $0. That can happen if your income is low, or if your family size is large enough that the protected amount covers your income. A $0 payment can still count as a qualifying payment toward forgiveness, if you are enrolled in the plan, you recertify each year, and you meet the other rules. Interest may still build up during a $0 payment period, so check your balance.

How long until my loans are forgiven under IDR?

It depends on the plan. New borrower IBR and PAYE generally forgive a remaining balance after 20 years of qualifying payments. Older borrower IBR and ICR generally forgive after 25 years. RAP is reported to have a 30 year forgiveness period, but that figure is from draft regulations and should be checked on the official page. PSLF is separate, and it forgives Direct Loans after 120 qualifying monthly payments, or 10 years, while working full time for a qualifying employer.

Conclusion

Income driven repayment sets your federal student loan payment from your income and family size, instead of from your loan balance alone. Your payment is a percentage of discretionary income, which is your adjusted gross income minus a protected amount based on the poverty guideline. The main plans are IBR, PAYE, and ICR, with IBR at 10 percent for new borrowers and 15 percent for older borrowers, PAYE at 10 percent, and ICR at 20 percent or a fixed 12 year payment, whichever is lower. SAVE has been ended, PAYE and ICR are being phased out, and a new plan, the Repayment Assistance Plan, is set to start for loans disbursed on or after July 1, 2026. A lower payment now can mean more interest and a longer term later. Use the loan simulator at studentaid.gov with your real figures, check the June 30, 2026 consolidation date if it applies to you, and recertify every year once you are enrolled.
