Income-Driven Repayment Plans Explained for 2026: IBR, PAYE, ICR and the SAVE Question

Federal income-driven repayment, usually shortened to IDR, is the family of student loan plans that sets your monthly payment from your income and family size instead of from your balance alone. It sounds simple, and the core math is, but the plan names stack up: IBR with two percentage branches, PAYE with tighter eligibility doors, ICR with two internal formulas, and SAVE, which has spent recent years in litigation limbo while its rules changed. This guide walks through each plan the same way the formulas do, with a worked example you can follow line by line. Two ground rules apply throughout. First, everything here is an estimate of the published math; your servicer and StudentAid.gov decide actual payments. Second, plan rules have changed repeatedly in recent years, so treat any article, including this one, as a snapshot to verify against current official guidance.

CHAPTER 01The Shared Idea Behind Income-Driven Repayment

Every IDR plan shares one skeleton. You take your adjusted gross income, subtract 150 percent of the federal poverty guideline for your family size, and the remainder is your discretionary income. The plan then charges a fixed percentage of that discretionary amount as your monthly payment. Different plans differ mainly in the percentage they charge, the length of their forgiveness timelines, and the eligibility rules that decide who can enroll. Once you see the skeleton, the alphabet soup stops being intimidating, because you are comparing the same input passed through slightly different dials.

The poverty guideline part of the formula does the quiet work. For 2026, the guideline for the 48 contiguous states and DC is $15,960 for a household of one, plus $5,680 for each additional person, with higher schedules for Alaska and Hawaii. Multiply the guideline by 1.5 and you have the income shield that IDR does not touch. A larger family raises the shield, which lowers discretionary income and therefore lowers every plan's payment at the same AGI. That single interaction explains most of why two borrowers with identical loans can owe very different amounts.

One more shared rule matters at the low end: when the computed payment works out to a small dollar amount, plans round payments under five dollars down to zero. A zero-dollar payment still counts as a payment on IDR timelines, which is why reporting household size accurately and recertifying on time genuinely matters even when money is tight. Estimates like the ones an income-driven repayment calculator produces follow the same rounding convention, so your preview matches the shape of the official math rather than a fantasy version of it.

CHAPTER 02IBR: 15 Percent, or 10 for Newer Borrowers

Income-Based Repayment, the oldest plan in the family, charges 15 percent of discretionary income to borrowers who first borrowed before July 1, 2014, and 10 percent to newer borrowers. That date split is the whole difference between the branches: same discretionary-income definition, same annual recertification rhythm, just a different multiplier. On our worked example, an AGI of $60,000 with a household of two produces discretionary income of $27,540, which puts the 15 percent branch at $344.25 per month and the 10 percent branch at $229.50 per month.

IBR also has a partial financial hardship test, and it is the part people skip. In plain terms, your IDR payment has to come in below what you would owe on the standard ten-year plan for IBR to be available in the first place. If the computed amount meets or exceeds the standard payment, the plan is effectively closed to you. A good estimate tool flags that condition rather than hiding it, because a plan you cannot enroll in is not a plan, whatever its percentage happens to be.

The forgiveness timeline for IBR runs 20 years for the newer 10 percent branch and 25 years for the older 15 percent branch, measured in qualifying payments. Treat those numbers as published terms rather than personal promises: eligibility, what counts, and even plan availability have shifted with policy changes. What IBR reliably offers is a ceiling tied to income, which is exactly what the hardship test was designed to guarantee.

CHAPTER 03PAYE: The 10 Percent Plan With Tighter Doors

Pay As You Earn charges 10 percent of discretionary income, the same rate as newer-borrower IBR, with a 20-year forgiveness timeline. Its catch is eligibility. PAYE was written for a narrower group of borrowers, tied to when you first borrowed and whether you were a new borrower on a specific date, and it carries its own partial financial hardship test on top. If your income is high relative to your debt, the hardship door closes exactly as it does for IBR, and the 10 percent rate becomes unreachable no matter how neatly the arithmetic would work.

The reason PAYE keeps showing up in conversations despite the narrow doors is simple: 10 percent of discretionary income with a 20-year clock is the gentlest standard combination in the IDR family for those who qualify. On the worked example, that is $229.50 per month against the $385.07 standard ten-year payment on a $35,000 balance at 5.8 percent. The gap between those two numbers is precisely what the hardship test is measuring, and when the gap disappears, so does the plan.

Because eligibility windows and even plan availability have changed with policy over the years, the practical advice is to check what your servicer currently offers rather than assuming PAYE is open. The percentage math on this page is stable and honest; the enrollment doors move. Estimating first, then confirming with the official application, keeps the two roles straight, and it protects you from building a budget around a rate you may not be able to access.

CHAPTER 04ICR: The Flexible but Less Generous Option

Income-Contingent Repayment is the universal backstop of the family: it is the plan nearly every federal Direct Loan borrower can access, including ones that other plans exclude, such as Parent PLUS loans after consolidation. The trade for that flexibility is a heavier formula. ICR charges 20 percent of discretionary income, or the fixed payment you would owe on a twelve-year standard schedule adjusted by an income factor, whichever is lower.

On the worked example, the 20 percent branch produces $459.00 per month, the heaviest payment in the IDR comparison at the same income. The twelve-year fixed branch can come in lower for some borrowers, but it depends on balance, rate and income in ways that are hard to preview without the servicer's own calculation. An honest estimate tool states which branch it computes; ours shows the 20 percent branch and labels the fixed branch as not computed, so you never mistake a preview for the full picture.

ICR's forgiveness timeline is 25 years of qualifying payments, the longest in the family. That combination of universal access, higher percentage and longer clock is why ICR rarely wins a straight comparison for borrowers who qualify for PAYE or newer IBR, and why it still matters as the option that exists when the others do not. It is worth knowing before you need it, because the years when the other doors close are exactly the years when a guaranteed-available option has value.

CHAPTER 05SAVE: Where It Stands and Why It Is Not Computed Here

The Saving on a Valuable Education plan was built to be the most generous IDR option, with formulas that went beyond the standard percentages, and millions of borrowers were moved toward it or enrolled in it. It then became the subject of litigation, and its rules and availability have changed while the court cases ran. Payments for many borrowers were paused or recalculated at different points, and the plan's future has remained uncertain in ways that make any single written description age quickly.

For that reason this guide, and the calculator behind it, do not compute SAVE. Producing a confident-looking SAVE payment while the plan sits in litigation limbo would be false precision, and false precision in this space costs real money. If you are on SAVE, were moved onto it, or are considering it, the only dependable source for its current status is StudentAid.gov and your servicer, and checking there takes minutes.

The honest framing is that SAVE is a plan whose formulas you may see again in some form, but whose present behavior you should verify rather than assume. Everything else in this guide, the discretionary-income definition, the IBR, PAYE and ICR percentages, and the standard-plan comparison, follows published formulas that are stable enough to estimate. SAVE gets the same treatment the moment its status stabilizes; until then, it gets a flag instead of a number.

CHAPTER 06Choosing Among Plans Without Guessing

A sensible sequence looks like this. Compute your discretionary income from your AGI and household size, because every plan starts there. Apply each available percentage, 15 or 10 for the IBR branches, 10 for PAYE if your eligibility window is open, 20 for ICR, and compare each result to your standard ten-year payment, which is also the hardship-test line. Anything at or above the standard amount is likely unavailable under hardship-tested plans, so the realistic menu is usually shorter than the full list of names.

Then add the situational layers that math alone cannot see: income stability, family plans, whether you expect your income to rise or fall, and how long you want to carry federal loans at all. For borrowers whose goal is clearing the debt fast at low total interest, comparing the IDR payment against an aggressive payoff plan is worth an hour; our debt payoff coach page walks that side of the decision. IDR is a safety design, not automatically a cheap one.

Finally, estimate with a tool, then decide with your servicer. The income-driven repayment calculator on this site computes the poverty shield, discretionary income, every branch it can honestly compute, and the standard-plan comparison, with the SAVE status flagged rather than guessed. The servicer's application produces the binding numbers from your actual tax data. Estimating first simply means you walk into that conversation already knowing which numbers should come out of it.

🔑 Key takeaways

• All IDR plans share one skeleton: AGI minus 150 percent of the poverty guideline, with each plan charging its own percentage of the remainder.
• The 2026 poverty guideline for the 48 states and DC is $15,960 for one person plus $5,680 per additional person; household size moves every payment.
• IBR charges 15 percent (older borrowers) or 10 percent (post-July-2014 borrowers); PAYE charges 10 percent with narrower eligibility; ICR charges 20 percent.
• Hardship-tested plans close when the computed payment reaches the standard 10-year amount, so the realistic menu is often shorter than the full list.
• SAVE is in litigation limbo and its status keeps changing; it is not computed here, and StudentAid.gov is the only current source.
• Estimates preview the math; your servicer and StudentAid.gov produce the binding numbers.
