IDR payments are monthly loan payments calculated based on your income, not on how much you borrowed

IDR stands for Income-Driven Repayment. It is a way to pay back federal student loans where your monthly payment is tied to what you earn right now, not to the size of your debt. If you earn less, you pay less. If you earn nothing, your payment can be zero. The payment recalculates once a year based on your most recent tax return or income statement.

The federal government offers four different IDR plans, each with different rules about how much of your income goes toward the payment and what happens to unpaid interest. They exist because standard 10-year repayment can be unaffordable when you graduate into a low-wage job or during periods of unemployment.

IDR is not forgiveness. You still owe the full loan amount. But if you stay on an IDR plan for 20 to 25 years (depending on the plan) and make every payment on time, any remaining balance is discharged — meaning you no longer owe it. This is called loan forgiveness, and it is the main reason borrowers choose IDR over standard repayment.

Key Takeaways

  • Your IDR payment is calculated from your income each year, usually resulting in a lower monthly amount than the standard 10-year plan.
  • Four IDR plans exist: PAYE, REPAYE, IBR, and ICR, each with different income percentages and forgiveness timelines.
  • You must recertify your income annually, usually by submitting your tax return to your loan servicer, or your payment will jump to a much higher amount.
  • Unpaid interest may capitalize (get added to your principal balance) depending on which plan you choose, potentially increasing what you owe over time.
  • After 20 to 25 years of payments, any remaining balance is forgiven, but forgiven amounts may be taxed as income in the year of forgiveness.

The four IDR plans and how they differ

The Revised Pay As You Earn (REPAYE) plan calculates your payment at 10 percent of your discretionary income — the difference between your adjusted gross income and 150 percent of the federal poverty line for your family size. Unpaid interest does not capitalize while you are on REPAYE, meaning it does not get added to your loan balance. Forgiveness happens after 25 years. REPAYE is available to all federal student loan borrowers.

The Pay As You Earn (PAYE) plan also uses 10 percent of discretionary income, but forgiveness happens after 20 years instead of 25. However, PAYE has an may be able to access requirement: you must have borrowed after October 1, 2007, and received a loan disbursement after October 1, 2011. Unpaid interest does not capitalize on PAYE either.

The Income-Based Repayment (IBR) plan uses either 10 or 15 percent of discretionary income depending on when you borrowed. If you borrowed before July 1, 2014, your payment is 15 percent and forgiveness happens after 25 years. If you borrowed after that date, your payment is 10 percent and forgiveness happens after 20 years. Unpaid interest does capitalize on IBR, meaning it gets added to your balance if you do not pay enough to cover it.

The Income-Contingent Repayment (ICR) plan is the oldest and least common. It uses 20 percent of discretionary income or a fixed amount based on a 12-year repayment schedule, whichever is higher. Forgiveness happens after 25 years, and unpaid interest capitalizes. ICR is mainly used by borrowers with Parent PLUS loans, which cannot use the other three plans.

How your payment gets calculated each year

When you first enroll in an IDR plan, your loan servicer asks for your income. You can provide your most recent tax return, a recent pay stub, or a statement of expected income if you have not filed taxes yet. The servicer uses this to calculate your discretionary income and then applies the plan's percentage — 10 percent for REPAYE and newer PAYE borrowers, 15 percent for older IBR borrowers, and so on.

Once a year, usually in the fall, you must recertify your income by submitting a new tax return or income statement. If you do not recertify, your servicer will use an estimate based on your prior year's income, and your payment will likely increase. If you miss recertification for more than a few months, your loan can be moved off IDR and back onto standard repayment, which is usually much more expensive.

Your payment can be as low as zero if your income is below the poverty line for your family size. Even at zero, you are still making progress toward forgiveness — the years count. However, unpaid interest still accrues (builds up) on most plans, so your balance may grow even though you are paying nothing.

What happens to interest you do not pay

On REPAYE and PAYE, unpaid interest does not capitalize. This means if your payment is $200 but your interest that month is $250, the extra $50 straightforward sits there and accrues. It does not get added to your principal balance. This is a significant advantage because it keeps your total debt from growing even when your payment is too small to cover interest.

On IBR and ICR, unpaid interest does capitalize. If you do not pay enough to cover the interest, the unpaid portion gets added to your principal balance at the end of the year. This means your loan grows larger, and next year's interest is calculated on a bigger number. Over time, this can substantially increase what you owe.

One exception: if you are on any IDR plan and your payment is zero because your income is below the poverty line, interest does not capitalize for the first three years. After three years, it does capitalize if you remain at zero payment.

Recertification and what happens if you miss it

Recertification is the annual process of telling your servicer your current income so they can recalculate your payment. You usually do this by logging into your servicer's website, uploading your tax return, or calling them directly. The important date is typically tied to the anniversary of when you enrolled in the plan, though servicers send reminders.

If you miss recertification, your servicer will estimate your income based on the prior year. If your income has dropped, this estimate will be too high and your payment will be higher than it should be. If you miss recertification for several months, your loan can be moved off IDR entirely and placed back on standard repayment, which can jump your payment from a few hundred dollars to over $1,000 per month depending on your loan balance.

If your income drops significantly — you lose your job, for example — you do not have to wait for the annual recertification. You can request an out-of-cycle recertification at any time. Your servicer will ask for proof of the income change, such as a recent pay stub or a letter from your employer.

Loan forgiveness after 20 or 25 years

The main benefit of IDR is that after you have made payments for 20 to 25 years (depending on your plan), any remaining balance is forgiven. You no longer owe it. This is especially valuable if you borrowed a large amount and your income stayed relatively low throughout your career.

However, the forgiven amount may be treated as taxable income in the year it is forgiven. If you have $100,000 forgiven, the IRS may count that as $100,000 of income for that tax year, potentially pushing you into a higher tax bracket and resulting in a large tax bill. Some states do not tax forgiven student loan debt, but others do. You should plan for this possibility by setting aside money or consulting a tax professional as you approach forgiveness.

Forgiveness is not automatic. Your servicer will notify you when you have reached the forgiveness point, but you may need to request the final discharge. Keep records of your payments and stay in contact with your servicer as you approach 20 or 25 years on the plan.

When IDR makes sense and when it does not

IDR is most useful if your loan balance is large relative to your income, or if your income is expected to be low for several years. For example, if you borrowed $80,000 and your starting salary is $35,000, standard repayment might require $800 per month, while an IDR plan might require $250. Over time, if your income rises, your IDR payment rises too, but you benefit from the lower payments in the early years.

IDR is less useful if your income is already high or if you plan to pay off your loans quickly. If you earn $100,000 and borrowed $30,000, your IDR payment might be nearly as high as standard repayment, and you would be giving up the simplicity of a fixed payment schedule.

IDR also requires discipline: you must recertify every year, keep your servicer updated on address changes, and track your progress toward forgiveness. If you forget to recertify, your payment can jump unexpectedly. If you are the type of borrower who prefers a straightforward, set-it-and-forget-it plan, standard repayment might be a better fit.

Frequently Asked Questions

Can I switch between IDR plans?

Yes. You can change plans at any time by contacting your servicer. However, if you switch from a plan that does not capitalize interest (REPAYE or PAYE) to one that does (IBR or ICR), any unpaid interest that has accrued will be capitalized when ready. Switching the other direction does not reverse capitalization that has already happened.

Does my spouse's income count toward my IDR payment?

Only if you are married and file taxes jointly. If you file separately, your spouse's income does not count. Some borrowers file separately specifically to keep their spouse's income off the calculation, though this has other tax consequences you should discuss with a tax professional.

What if my income goes up significantly?

Your IDR payment will increase at the next annual recertification. There is no cap on how high your payment can go. Eventually, your payment might equal or exceed what you would pay on standard repayment. At that point, you might consider switching plans.

Can I get IDR on private student loans?

No. IDR plans are only available for federal student loans. Private loans have their own repayment options, which vary by lender and typically do not include income-driven plans.

What happens to IDR if I go into deferment or forbearance?

If you pause payments through deferment or forbearance, you are temporarily off your IDR plan. When you resume payments, you can go back on IDR, but you will need to recertify your income. Time spent in deferment or forbearance does not count toward your 20 or 25 years of payments for forgiveness purposes.
