What "Minimum Payments" Actually Cost

Carrying a credit card balance at 24.99% APR is the single most expensive thing the average household does. This tool runs the brutal math on minimum-payment payoff timelines, then shows what even modest extra payments unlock.

"The carrying-a-balance-builds-credit myth has cost a generation of Americans more than any tax law on record."

Current credit card balance ($)
Average US revolving balance per household: ~$6,500. Many young earners are higher.
APR (%)
2026 average: ~24.99%. Store cards often 27–31%. Some intro offers 0% for 12–18 months.
Minimum payment formula (% of balance)
Most cards: 2% of balance OR $25, whichever is greater.
Extra payment beyond minimum ($/mo)
Even $25/mo extra changes the math materially.
PAYING ONLY THE MINIMUM

The extra-payment lever

The 24.99% APR is the highest rate of return you can guarantee yourself in personal finance — by paying it off. A dollar that retires a 24.99% credit card balance is mathematically equivalent to a dollar earning 24.99% in an investment account, after tax. There is no equity portfolio that can offer that return. Pay off the cards before contributing to a Roth (beyond the employer match), before any taxable brokerage, before saving for any goal beyond the emergency fund.
From the Money Reality series. Ch 12 (HS Edition) introduces this. Ch 12 (College Edition) gets specific on the student-card trap. Ch 11 (First Job Edition) covers the post-graduation credit-utilization period when the trap snaps shut.

Illustrative only. Real credit card minimum-payment formulas vary by issuer (typically the greater of $25, 1-3% of balance, or interest + 1% of principal). The CARD Act of 2009 set floor rules. Late fees, over-limit fees, and penalty APRs not modeled. Not financial advice; if you carry a balance, call your issuer and ask for a rate reduction — it works more often than people expect.
