New on FinoLib · Volume V: Personal Finance
I have added a new article to FinoLib, my finance education website: Repayment Assistance Plan (RAP): How a Payment Is Applied, part of Volume V: Personal Finance. It is part 2 of a 2-part guide. This page gives you the core of the topic in expert but plain language; the full article goes much deeper.
A closer look
A 529 plan is a state-sponsored investment account for education expenses: contributions aren’t federally deductible, but growth is tax-deferred and withdrawals for qualified expenses are entirely federal-income-tax-free — many states add their own deduction for contributions on top. OBBBA meaningfully expanded what counts as “qualified” for distributions after July 4, 2025 (with the higher K-12 cap starting in 2026):
A worked example
Worked Example — Saving From Birth
$200 contributed monthly from birth through age 18 (216 months), growing at an assumed 6% average annual return, compounds to ≈$77,470 — of which only $43,200 was actually contributed. The remaining ≈$34,270 is tax-free growth, entirely untaxed at withdrawal provided it’s used for a qualified expense under the expanded 2026 rules above.
Under the hood
Under the Hood: How a RAP Payment Is Applied
The statute fixes the order: each payment goes first to the month’s interest, then to fees, then to principal, and principal due but not paid is deferred rather than added to the balance (20 U.S.C. §1087e(q)). If an on-time payment does not cover the month’s interest, the shortfall is not charged. If it reduces principal by less than $50, the Secretary reduces principal by the lesser of $50 or the payment, minus whatever the payment already applied to principal. So an on-time RAP balance can never grow, and even a payment that covers no principal at all retires up to $50 of it. Two details carry real money.
Decision rule
Borrowing: take federal Direct Loans before any private loan, and keep total borrowing at or below the first-year salary you can expect in your field; at 6.52%, a 10-year payment on a balance equal to salary is about 13.6% of gross pay. Repaying a loan first disbursed on or after July 1, 2026: if you work, or expect to work, for a government or 501(c)(3) employer, enroll in RAP.
The costliest mistake
Letting a federal loan default when RAP would have cost almost nothing. Take a single borrower earning $30,000 with AGI of $30,000 and no dependents. On RAP the payment is $30,000 × 2% ÷ 12 = $50.00 a month. In default, once garnishment is active, the government may take up to 15% of disposable pay. Illustratively, with no state tax: $30,000 − $1,420 federal income tax − $2,295 Social Security and Medicare = $26,285; × 15% = $3,942.75 a year, or $328.56 a month.
Analogy
RAP is priced like a sliding-scale clinic with a ratchet on the door. What you pay depends on which income band you stand in, not on how much you owe, and every on-time month moves the balance toward the exit, by up to $50 even when the payment covers none of the interest. IBR works more like a tax on income above an allowance (150% of the poverty line), so its payment rises smoothly with income instead of in steps.
Why It Matters
Public Service Loan Forgiveness itself has not been eliminated — despite widespread confusion in 2026, Congress did not repeal it, and the core 120-qualifying-payments, 10-year structure for full-time work at a qualifying government or 501(c)(3) nonprofit employer is unchanged.
Recap
Federal student loans beat private ones less on rate than on protections: income-driven repayment, PSLF, deferment and forbearance, and discharge on death or total and permanent disability. For a loan first disbursed on or after July 1, 2026, only two plans remain, the Tiered Standard Plan and the Repayment Assistance Plan (RAP), which charges 1% to 10% of your whole AGI by $10,000 bands, less $50 a month per dependent…
