The SAVE borrowers who open the mail get the lowest bill. The ones who don't get the cliff.

Around July 1, days from now, federal loan servicers begin sending notices to the roughly 7.5 million borrowers still parked in the SAVE planSAVE planThe Saving on a Valuable Education plan, a low-payment income-driven repayment program created in 2023 and later blocked by federal courts, which is why its enrollees were parked in a payment pause.'s forbearanceforbearanceA temporary pause on required loan payments; here, SAVE borrowers owe $0 a month, but interest has been adding to their balance again since August 1, 2025. (about 8 million were enrolled at the peak), instructing each to exit the court-blocked plan and pick a legal one. Each notice opens a window of at least 90 days to choose, and the department has signaled the forbearance will be wound down across the third quarter of 2026. The notices are expected in waves, longest-enrolled borrowers first.

The same transition stands up two new plans created by the 2025 budget law: the income-based Repayment Assistance Plan (RAP) and a fixed-term Tiered Standard planTiered Standard planA new fixed-term plan where the payoff period is set by how much you owe (10, 15, 20 or 25 years) rather than by your income; it does not count toward Public Service Loan Forgiveness.. Borrowers who do nothing within their window get automatically enrolled into, in the Department of Education's own framing, 'either the Standard Repayment PlanStandard Repayment PlanThe traditional 10-year fixed-payment federal student-loan plan., or the new Tiered Standard Plan.'

Much of the coverage frames RAP as the costly new regime that replaces a generous one. That reading is not wrong: measured against the $0 these borrowers pay today, every plan is an increase, and RAP at about $167 a month is a real cash shock. We wanted to test a narrower, more consequential question, holding the baseline fixed at the set of plans a borrower can actually land on.

For a typical SAVE borrower, is the act of choosing RAP the expensive move, or is the expensive move doing nothing at all?

The answer, built up from the statute, is that within the choice set the popular framing is backwards. The borrower who opens the envelope and actively picks RAP lands on the lowest monthly payment available to this group. The borrower who ignores it gets swept onto a higher one. Both readings are true at once because they use different baselines: 'RAP is more than SAVE' compares to a $0 payment that was always temporary, while 'RAP is the cheapest choice' compares to the plans you can be put on now. This piece is about the second baseline.

We built the payment ladder for one concrete, defensible archetype and derived every rung from the underlying rules rather than from secondary calculators, which often disagree with each other. The archetype: a $35,000 balance, $50,000 adjusted gross income (AGI), single, no dependents, close to the median federal borrower. We amortize fixed-term plans at 6% throughout, meaning we spread each one into equal monthly payments at a single 6% interest rate so the plans can be compared on the same footing.

Step 1, what SAVE was paying. SAVE set undergraduate payments at 5% of 'discretionary incomediscretionary incomeIncome above a protected floor (225% of the poverty line for SAVE, 150% for IBR); these plans set payments off this slice, while RAP uses your whole income.,' meaning income above 225% of the federal poverty line. For a household of one in 2025 the poverty guidelinepoverty guidelineAn annual income figure published by the federal government (HHS) used to decide eligibility and payment sizes for many programs; in 2025 it is $15,650 for a single-person household in the contiguous states. is $15,650, so 225% is $35,213. That leaves $14,788 of discretionary income, times 5%, divided by 12: about $62 a month as designed. But SAVE is in forbearance, so the borrower actually pays $0 today, while interest has accrued again since August 1, 2025.

Step 2, what RAP charges. RAP is not a percentage of discretionary income. It is a flat percentage of total AGI, divided by 12, minus $50 per dependent, with a $10 monthly minimum. The percentage climbs by income band: it is 1% on AGI from $10,001 to $20,000 and rises one point per $10,000 of income, reaching 10% above $100,000. Our $50,000 earner sits in the $40,001-to-$50,000 band, which is taxed at 4%. So 4% of $50,000 is $2,000 a year, or about $167 a month. With no dependents, nothing is subtracted.

Step 3, the other rungs. IBR charges 10% of income above 150% of the poverty line ($23,475 for a household of one), which is $26,525 of discretionary income times 10%, or about $221 a month. The 10-year Standard plan amortizes the full $35,000 at 6% into 120 payments of about $389. The Tiered Standard plan sets the term by balance, 15 years for a $25,000-to-$50,000 balance, which at 6% works out to about $295 a month. Lined up, RAP is the lowest bill a SAVE borrower can choose, and both auto-sweep destinations sit above it.

That band structure has a sharp edge. Because the rate applies to your whole income rather than only the dollars above a line, crossing a band boundary reprices everything. Earn $50,000 and you pay 4%, or $2,000 a year. Earn one dollar more and the whole $50,001 is charged at 5%, jumping the annual bill to about $2,500. That is a $500 swing from a single dollar of income, the opposite of how income-tax brackets work, where only the dollars above the line face the higher rate.

RAP wins the monthly contest for a reason that is also its catch: it spreads the debt over the longest horizon of any option here. RAP forgives whatever is left after 30 years. Standard clears the loan in 10, Tiered Standard in 15 for this balance, and IBR forgives after 20 for newer borrowers. A lower bill stretched over three decades can mean paying longer, and more in total interest, than the 10-year plan. The RAP bargain is a cash-flow bargain, more money in your pocket each month, not a lifetime-cost bargain.

There is a twist that makes RAP unusual. Its $167 payment does not even cover the monthly interest on $35,000 at 6%, which runs about $175. Under most plans, that shortfall would swell the balance, the phenomenon called negative amortizationnegative amortizationWhen your payment is smaller than the monthly interest, so the unpaid interest would normally swell the balance; RAP waives that unpaid interest instead.. RAP handles it two ways the law spells out: the unpaid interest is waived rather than added, and if your payment does not reduce principalprincipalThe amount you originally borrowed and still owe, separate from the interest charged on top of it. by at least $50 in a month, the government chips in a subsidy so the principal falls by $50 anyway. The result is that a RAP borrower's balance shrinks by roughly $600 in year one, even while paying less than the interest.

Set against the alternatives, the contrast is stark. Sitting in forbearance is the only path on which the debt actually grows, by about $2,100 in a year as interest piles on with no payment against it. Tiered Standard cuts the balance by roughly $1,490 in year one and the Standard plan by about $2,600, because their higher payments pay down principal faster. Inaction is not a neutral hold; it is the single option that leaves you owing more.

The averages hide where the real damage lands. Start with public servants chasing PSLF, which cancels the balance after 120 qualifying payments for people in government or nonprofit work. Only payments made on certain plans count. RAP qualifies. The new Tiered Standard plan does not count at all, so a teacher or nurse swept onto it earns zero credit toward forgiveness while believing they are paying their loans down. The legacy 10-year Standard plan technically qualifies, but it clears the loan in exactly 120 months, leaving nothing extra to forgive. For a PSLF-track borrower, the auto-sweepauto-sweepThe automatic enrollment of a borrower who does not actively choose a plan within the notice window; ED says non-responders go to 'either' the Standard or the Tiered Standard plan. is the worst outcome on the board, and it is the default.

Next, the lowest earners. RAP carries a $10 monthly minimum even for someone earning almost nothing, whereas SAVE could put a low-income borrower's payment at $0. For a household living paycheck to paycheck, the move from $0 to a required $10, with the credit-reporting consequences of missing it, is not trivial. And finally, everyone caught by ED's own vagueness: the department says non-responders go to 'either' the Standard or the Tiered Standard plan without saying which, a roughly $94-a-month difference for this archetype that the borrower does not get to pick.

The throughline is that the cost of inaction is concentrated, not average. The median borrower who ignores the notice ends up on a pricier plan than they had to. But the public servant, the lowest earner and anyone with a thin cash cushion can lose something harder to recover than a few dollars a month: forgiveness credit, a clean credit report, or simply the choice itself.

Framed against the $0 of forbearance, RAP looks like the expensive new world. Framed against the plans a SAVE borrower can actually be put on this summer, it is the cheapest monthly bill, and the costly outcome is the one that requires no decision at all. The honest caveat is that RAP's low payment is bought with the longest payoff, so cheap-per-month and cheap-overall are not the same thing. But the practical instruction is simple: the borrower who opens the mail and chooses gets the lowest bill and keeps every option open. The borrower who does not gets the cliff.
