The repayment switch that only goes one way

If your loans are on SAVE, a clock may already be running. Your servicer's notice to leave starts a 90-day window to pick a plan, and the window runs from that notice rather than from a date in the news. Miss it and you are enrolled automatically into Standard or the new Tiered Standard. Neither one is income-driven and neither one forgives anything, so the automatic outcome is the one that ignores what you earn.

What almost nobody mentions is that the plans do not swap freely. One of the choices in front of you is much easier to walk into than to walk out of, and the borrowers it was designed for are the ones least able to leave.

This article is about that asymmetry, and about what these plans cost once you look past the monthly payment. Every figure in it comes from the same model that runs the calculator, at the 6.5 percent federal rate the tool uses.

Dollar amounts throughout have been rounded for readability, so the tables will not always add up to the cent. Figures set by statute, such as the $50 dependent reduction and the $10 minimum payment, are exact.

The menu, on one balance

Take somebody who finished a doctoral program owing about $79,000. That is the median debt at graduation across the 591 doctoral programs in the federal field-of-study data. Put them on an income of about $47,000, the twenty-fifth percentile of the 825 occupational medians in the wage data. A balance about seventy percent larger than the salary, which is an ordinary shape for anyone who borrowed for graduate school.

Five plans, same balance, same person:

Read the payment column and the total column together, because they run in opposite directions. RAP has the smallest payment on the page and the largest total on the page. The balance clears a couple of months before the thirty-year mark, so the forgiveness that makes RAP sound generous never arrives for this borrower. They simply pay, for thirty years. That is about $56,000 more than the ten-year plan and about $58,000 more than the IBR row, tax included.

The tax is the newest part of this. Since January 1, 2026 a discharged federal balance is ordinary income in the year it is written off, so the roughly $99,000 forgiven on the IBR row lands on a tax return. The estimate here is federal only, single filer, standard deduction, which means the real bill can only be higher. Public Service Loan Forgiveness is the exception, and that discharge is not taxed.

None of which makes the ten-year plan affordable. About $900 a month on a $47,000 income is not a plan, it is a wish. The point is narrower and it matters more: the plan with the lowest payment is not the cheapest plan, and on this balance it is the most expensive one on offer.

What carries in, and what does not

Two rules govern moving between plans, and they point in opposite directions.

Payments you have already made under any income-driven plan count toward discharge under RAP. Spend five years on an older plan and switch, and those sixty payments come with you. For the borrower above, that credit moves the RAP discharge from year 30 to year 25, turns a plan that forgave nothing into one that writes off about $42,000, and brings the total, discharge tax included, down from about $164,000 to about $125,000. Roughly $39,000, for having already been paying.

Going the other way, a RAP payment counts toward IBR, ICR or PAYE only in a month where it was at least as large as the ten-year Standard payment on that balance. That one condition is the whole exit, and it is written so that it almost never fires for the people RAP is aimed at. The low payment that makes RAP bearable is exactly what fails the test.

Here is where the bar sits, using the median debt at four credential levels from the same field-of-study data:

The right-hand column is the income at which a RAP payment finally equals what the ten-year plan would have charged. Below it, the months are not counting. Of the 825 occupations in the federal wage data, 396 have a median wage under the figure in the top row, so on a typical undergraduate balance the door is already shut for people in about half of them.

Payments do grow, because incomes grow, so a borrower who stays long enough will eventually clear the bar. That is less comfort than it sounds. The doctoral borrower on $47,000 has 9 of 358 RAP months counting toward a return, and the first of them arrives in year 29. On a $23,000 balance at the same income, 40 of 149 months count and the first lands in year 10. The months that count are always the last ones. In the years when somebody would actually want to change their mind, none of them do.

So the honest summary is that switching into RAP is close to a one-way door, and the lower your income relative to your balance, the more firmly it closes. Which is the opposite of how an exception clause reads.

What the children do to the arithmetic

RAP subtracts $50 a month from the payment for each dependent you claim on your federal tax return, and no payment can fall below $10. Those two figures are statutory, so they are exact rather than estimated.

For a household paying for childcare, that reduction is not a rounding detail. On the same $79,000 balance at $47,000 of income:

Each dependent is worth roughly $15,000 over the life of the loan, and the smaller payment is only part of the reason. Recall that without children this borrower clears the balance about two months before the thirty-year mark and is forgiven nothing. The reduction pushes the payoff past that line, so the write-off finally arrives, and on this balance the forgiveness moves the total more than the monthly saving does.

Then the same reduction works against you. The exit test compares your RAP payment against the ten-year Standard payment, and the reduction makes your payment smaller while leaving the bar exactly where it was. Every dependent therefore raises the income you need before a RAP month counts toward IBR, by $6,000 each. Without children this borrower needs about $108,000. With two, about $120,000. With three, about $126,000, and at $47,000 they are paying the $10 statutory minimum, which is as far from the $900 bar as this plan can put them.

That is the whole asymmetry in miniature. The provision that makes the plan survivable in the month you are living through is the provision that keeps you in it, and it applies hardest to the households with the least room to absorb either outcome. Childcare is competing for the same money as the payment, on a schedule that does not care which plan you picked, and the plan leaving the most in your account each month is the one costing the most by the end.

That can still be the right trade. Thirty years of a payment you can actually make beats ten years of one you cannot. It is worth making on purpose rather than discovering later.

Paying extra only pays on a plan that does not forgive

Take the same borrower and find $200 a month somewhere.

On RAP, that extra clears the loan in about 24 years instead of about 30, and costs about $3,000 more in total. Five and a half years of your life for around $3,000 is a trade plenty of people would take, and it is a real one.

On the IBR row, the same $200 a month costs about $33,000 more and does not save a single month. The discharge still arrives at year 20 either way. Every extra dollar simply shrinks the amount that was going to be written off, and then the smaller write-off is taxed as well. Prepaying is worth a great deal on a plan that forgives nothing and very little on a plan that does.

That fork is the thing a comparison table cannot show you, because every row in one holds a single plan constant for thirty years, while the decision you actually face is a sequence. The tool prices both arms of it: ride the minimum to a taxed discharge, or point money at the balance and finish early.

What no plan touches

Private loans sit outside all of this. No federal plan forgives them, none of them lowers the payment when your income falls, and nothing about them changes when you switch.

Federal loans work the other way, and that arithmetic surprises people. Several federal loans do not mean several income-driven payments. The plan sizes one payment from your income and that payment covers all of them. Split the $79,000 above across two federal loans at different rates and the RAP payment is still about $160 a month rather than double that. If you have been adding up per-loan estimates from a servicer's website, the total you are dreading may not exist.

What the tool will not do is tell you which row to pick. It prices them. Whether a smaller payment for thirty years is worth more to you than a bigger one for ten is a question about your life and about how much certainty you want.

Two things to find out before you choose

Both of them live with your servicer rather than in any calculator, and both are worth a phone call.

The first is how many qualifying payments you have already made. That count carries into RAP in full, and for somebody who has been paying for years it is worth tens of thousands of dollars. Ask for the number of payments rather than the number of years, because discharge is counted in months.

The second is when your first federal loan was disbursed. A first loan before July 1, 2014 puts you on the older version of IBR, at 15 percent of discretionary income with forgiveness at 25 years, instead of 10 percent and 20 years. And loans originated on or after July 1, 2026 cannot use IBR at all. If your loans came before that date you have an option new borrowers do not, which is exactly why the choice deserves an evening rather than whichever plan your servicer suggests first.

It is also why consolidation deserves its own evening. A Direct Consolidation Loan is first disbursed on the day it is made, so consolidating after that date closes the older plans for every federal loan you hold, the pre-2026 ones included. What that costs, and why it lands hardest on parent borrowers, is a separate piece.

Run it on your own balance

The repayment comparison is free, needs no login, and asks for nothing that identifies you. Put in what you owe, what you earn and how many payments you have already made, and it will lay every plan out side by side with the count-back rule applied to your numbers instead of to the example above.

Then look at the last column before you look at the first one.

This is not financial advice. Everything here is an educational estimate produced by a model, using national data and a single set of assumptions about rates, income growth and taxes. Your own balance, interest rates, family size and state will move these numbers, sometimes by a lot. Nothing on this page is a recommendation to choose any particular plan.

Before you commit to a repayment plan, talk to somebody who can see your actual account. Free help exists and is worth using: a nonprofit student loan counselor can go through your options with you at no cost, and a financial advisor can weigh a thirty-year payment against everything else you are saving for.
