There is a box on your credit card statement, required by federal law, that tells you how long it will take to pay off your balance if you only ever pay the minimum. Most people read the number, assume it’s a scare tactic, and pay the minimum anyway.
The number is not a scare tactic. It is arithmetic, and the arithmetic is worse than it looks because of one design detail almost nobody notices.
What the minimum payment is made of
There is no universal minimum payment formula. The CFPB, reviewing the credit card market, has found that minimum payment formulas vary widely across issuers in both the amount and the complexity of the calculation. Your cardholder agreement has yours.
A common structure looks like this: a small percentage of the balance — often 1% or 2% — plus the interest and fees assessed that month, subject to a floor of $25 or $35. Some issuers use a flat percentage of the balance with no interest add-on, which is considerably worse.
Take the first version, at 1% plus interest with a $25 floor, and a $5,000 balance. For the interest rate, use the Federal Reserve’s G.19 release: for the second quarter of 2026, the average rate on credit card accounts assessed interest at commercial banks was 22.15%, and the average across all accounts was 20.94%.
At 22.15%, one month’s interest on $5,000 is $92.29. The minimum payment is $92.29 plus 1% of the balance, or $142.29.
Of that first $142.29 payment, $92.29 is interest. Exactly $50 touches the debt. You paid 65 cents of every dollar for the privilege of not having paid yet.
The detail that turns years into decades
Fifty dollars a month against $5,000 would still be ten years. The reason it takes nineteen is that the minimum payment does not stay at $142.29.
It is a percentage of the balance. As the balance falls, the required payment falls with it. The payment shrinks in lockstep with your progress, so the pace of progress never accelerates. That is the whole mechanism.
Running the full amortization on $5,000 at 22.15%, paying exactly the minimum every month and never charging anything else:
| Approach | Time to payoff | Interest paid | Total paid |
|---|---|---|---|
| Minimum only (1% + interest) | 19 years, 0 months | $8,021 | $13,021 |
| $142.29/month, frozen | 4 years, 10 months | $3,137 | $8,137 |
| $200/month | 2 years, 10 months | $1,768 | $6,768 |
The first two rows are the same payment. The only difference is that in the second row the payment is not allowed to shrink. That single change takes fourteen years and $4,884 off the debt.
You do not need more money to move from row one to row two. You need a fixed amount instead of a percentage.
The box on your statement already says this
The disclosure comes from the Credit CARD Act of 2009, implemented in Regulation Z at 12 CFR 1026.7(b)(12), with the calculation method set out in Appendix M1 to Part 1026. Your issuer has to print a bolded “Minimum Payment Warning,” the number of years to payoff at the minimum, the total you’d pay, and — this is the useful part — the fixed monthly payment that would clear the balance in 36 months, plus what you’d save by paying it.
For the $5,000 example, the 36-month figure is about $191 a month, roughly $6,890 in total. That is $49 a month more than the first minimum payment, and it saves about $6,130.
If negative amortization would occur — if the minimum payment doesn’t even cover the interest — the issuer has to print a different warning instead, stating that even with no further charges, paying only the minimum will never pay off the balance.
When paying the minimum is the right call
There is a version of “just pay the minimum” that is correct, and it is worth saying plainly because the alternative advice gets people into trouble.
If money is genuinely short this month, pay the minimum on time rather than skipping the payment or paying late. A minimum payment made by the due date keeps the account current. A payment 30 days late gets reported to the credit bureaus and stays on your report for years, and it can trigger a penalty rate on the account. The interest cost of one month at the minimum is a rounding error next to that.
The same logic applies when you’re paying down multiple cards. You pay the minimum on all of them to keep every account current, and put everything else against one — highest rate first if you want the least interest, smallest balance first if you want the momentum. Both work. Paying the minimum on all of them and nothing extra on any is the one approach that doesn’t.
The pattern
Minimum payments are not a recommendation. They are the smallest amount the issuer will accept without treating you as delinquent, and the percentage-of-balance structure means that number falls exactly as fast as your balance does.
Pick a fixed dollar amount — anything at or above today’s minimum — set it as an autopay, and don’t lower it as the balance drops. That is the entire intervention. Everything else about credit card debt is a variation on that one number refusing to move.
