Best student loan repayment plan for $250k

On $250k of student loans the plan sets both the monthly payment — $423 on RAP against $2,839 on the standard 10-year plan at a $75k income — and what the loan costs in total. There are two answers, because Public Service Loan Forgiveness discharges the balance tax-free after 120 payments and everyone else pays to the end or to a taxable write-off. Every figure below is a full year-by-year projection: single filer in Texas, 28 years old, income growing 4% a year, 6.5% federal loans taken in 2026, run through age 60 so a 30-year RAP term and its forgiveness tax fall inside the window.

The plans compared for $250k

Payments start from a $75k salary and rise with it. RAP is the only income-driven plan open to loans taken from July 2026; IBR stays available to older loans; PSLF is a program layered on either one. "Total" is every payment plus the tax charged in the year a balance is forgiven.

$250k student loan monthly payment by income

The standard payment never moves — $2,839 a month for 120 months, whatever the salary. The income-driven payments do: RAP takes 1–10% of AGI by $10,000 band, IBR 10% of income above $23,940. The last two columns give each income its own verdict, from the same projections as the table above.

† IBR, available only to loans taken before July 2026, costs less than either open plan at this income.

The same ladder at every balance, with the crossover income where RAP stops being the lower payment, is on RAP vs IBR; the RAP formula by AGI and dependents is on the RAP calculator.

Every balance at a $75k income

Each row is its own set of projections, not a scaling of this page's. At $75k the standard plan is cheapest at 9 of the 11 balances and RAP at 2: at $30k RAP's income-based payment is at or above the ten-year payment, so the loan clears sooner with less interest; at $40k it starts below the ten-year payment but rises past it with income and still clears the loan before year 30. The full balance-by-income matrix runs the same comparison at four incomes.

What decides it

• Public service. PSLF discharges whatever is left after the 120th qualifying payment, tax-free, so the lowest qualifying payment wins and a large remaining balance is the point, not a problem. Here RAP + PSLF pays $68,768 and $244,000 is written off at 38. The plan-by-plan version is on best repayment plan for PSLF.
• Not public service, balance large next to income. RAP's payment is a share of AGI, not of the loan; unpaid interest is waived, the balance falls by at least $50 a month (the payment, if less), and whatever remains at 30 years is forgiven and taxed as income that year. On $250k at $75k that is $182,844 forgiven at 58 and $42,835 of tax on it — see the forgiveness tax bomb calculator.
• Not public service, payment affordable. The standard plan's $2,839 a month retires $250k in ten years with $90,644 of interest, the least of any plan. Refinancing to a lower private rate lowers that interest but permanently gives up income-driven plans, PSLF and federal discharge protections.

Educational comparison, not advice. Figures are one persona — single filer in Texas, 28 years old, income growing 4% a year, 6.5% federal loans taken in 2026, run through age 60 so a 30-year RAP term and its forgiveness tax fall inside the window — run through Coastline's projection engine; a different income path, state, filing status or rate changes them. IBR is modelled on its post-2014 terms (10% of income above 150% of the poverty line, capped at the 10-year standard payment, forgiveness at 20 years); RAP's per-dependent reduction counts children aged 0–23. Repayment rules change often — verify current terms with your servicer and studentaid.gov, and model your own balance in the calculator.

What refinancing a large balance quietly gives up

A lower interest rate is tempting on a balance this size, and private refinancing dangles exactly that. The trade is bigger than the rate, though, and it's permanent. Refinancing federal loans with a private lender converts them into a private loan and forfeits the entire federal toolkit: Public Service Loan Forgiveness, income-driven repayment, and the borrower protections that come with federal debt.

For someone with a secure, high income and no path to forgiveness, that trade can still make sense, since a lower rate on a big balance saves real money over the years. But it is a one-way door. Once the loans are private, you cannot switch back if your income drops, your job changes, or you land a public-service role that would have qualified you for forgiveness.

Weigh it against the flexibility you'd surrender, not just the rate you'd gain. On a balance this large, keep an emergency fund and confirm you'll never want the federal options before you close that door, and check the current federal terms first.

What a twenty-year payoff costs a retirement account

A balance this large is usually repaid across decades, and the decades are the point. Money directed at a loan is money not compounding somewhere else, and the years given up are the earliest ones — the contributions with the longest runway ahead of them, which is where most of a retirement balance ultimately comes from.

That does not make aggressive repayment wrong. It does mean the comparison is not simply the loan's rate against an expected market return. It is the certain, immediate return of clearing debt against decades of tax-advantaged growth on the same dollars — plus the employer match that many borrowers give up while they focus on the loan, which is the one return that reliably beats both.

The ordering that survives scrutiny is usually to capture the full match first, then decide how to divide what is left between the balance and the investment account.
