What this choice actually costs you
The payment shock, in actual dollars
Meet Dana: single, $65,000 AGI, $45,000 in Direct Loans, one of the 7 million borrowers leaving SAVE. Under SAVE she paid about $121 a month, 5% of income above 225% of the poverty line. That number is gone.
Her four real options now: RAP at roughly $325 a month (6% of her full AGI, divided by twelve), legacy IBR at about $342 (10% of income above 150% FPL), or the 10-year Standard plan at roughly $511. Doing nothing is the worst option: after her 90-day window closes, her servicer places her on Standard automatically, at the highest payment with no forgiveness track.
The lesson from Dana's numbers: the cheapest living plan for her is RAP by a whisker over IBR, but the ranking flips with income and family size. Run your own numbers in the simulator above before your notice arrives, not after.
RAP is a staircase, not a curve, and small raises can cost real money
RAP calculates payments unlike any previous IDR plan: a flat percentage of your entire AGI, stepping up 1 point per $10,000 income bracket, 1% up to $20,000, 5% in the fifties, 10% above $100,000. No poverty-line deduction, no discretionary-income math.
The staircase has sharp edges. Earn $60,000 and you pay 5% ($250/month); a $1,000 raise to $61,000 bumps the whole AGI into the 6% tier ($305/month): a $660-a-year payment increase from a $1,000 raise. Timing bonuses and Roth conversions around bracket edges suddenly matters for student loans, not just taxes.
Three softeners are built in: $50 per month per dependent comes off the payment, unpaid interest is fully waived each month (your balance never grows), and the government adds up to $50 monthly toward principal when your payment covers less than that. The floor is $10 a month: the $0 payment died with SAVE.
Ten tax-free years vs thirty taxable ones — the forgiveness gap
If you work full-time for a government agency or 501(c)(3), the comparison ends quickly: PSLF cancels the entire remaining balance after 120 qualifying payments, tax-free by statute. Every payment you already made under SAVE while publicly employed still counts. Nothing in the private-sector column competes with that.
Everyone else is on RAP's 30-year road, 360 payments before forgiveness, and the canceled balance is treated as taxable income that year. A $40,000 balance forgiven in 2056 could add roughly $8,000-$10,000 to that year's tax bill at today's rates. Plan for it or pay the balance off early; payments simply stop the month you hit zero.
Watch the calendar, because doors are closing in order: new loans or consolidations from July 1, 2026 lock all your federal loans into RAP or Standard only; PAYE and ICR sunset June 30, 2028; legacy IBR is the one older plan that survives. If keeping IBR access matters to you, do not consolidate casually.
