How long will it take to pay off my credit card debt?
A $5,000 balance at 21% APR takes 18 years 9 months at minimum payments and costs $7,584.36 in interest. Pay a fixed $300 a month instead and it is gone in 20 months for $963.41. The difference is the minimum-payment trap, and it is written into the math of your statement.

vs 20 months / $963.41 at a fixed $300 a month.
minimum = interest + 1% of balance, $25 floor · same balance
| Monthly payment | Payoff time | Total interest |
|---|---|---|
| Minimum only (~$125 falling) | 225 months | $7,584.36 |
| Fixed $200 | 34 months | $1,633.20 |
| Fixed $300 | 20 months | $963.41 |
Why the minimum stretches into decades
A minimum payment is recalculated every month as roughly the month's interest plus 1% of the balance, with a $25 floor. Because interest is a percentage of the balance, each minimum shrinks as the balance shrinks, so the principal barely moves. In the first year at minimums you pay about $1,420 and the balance only falls by roughly $700; the rest is the interest column growing. This is not a flaw in your discipline, it is the mechanism doing exactly what it was priced to do.
Your card statement already shows this. Since the CARD Act of 2009, every statement carries a Minimum Payment Warning box that states how many years the minimum takes and how much it costs, side by side with a fixed-payment alternative. Find the box; the two numbers there are the whole story of this page, personalized to your balance.

What to do with these numbers
Every extra $50 a month roughly halves the remaining time at the start of the curve: $200 takes 34 months, $300 takes 20. That leverage is steepest early because early payments attack a balance that is still generating $87.50 of interest every single month. The practical advice is mechanical: pick the largest fixed payment your budget can sustain for 20 months, automate it, and stop adding new charges to the card while it runs.
Educational estimates, not financial advice. Assumes a constant 21% APR, no new purchases, and minimums computed as interest + 1% of balance with a $25 floor. Real statements vary. Talk to a licensed professional before acting on these figures.
Common questions
How long does it take to pay off $5,000 in credit card debt?
At minimum payments with a 21% APR: about 225 months (18 years 9 months) and $7,584.36 in interest. At a fixed $300 a month: 20 months and $963.41 in interest.
Why does the minimum payment take so long?
The minimum is recalculated monthly as roughly interest plus 1% of the balance, so it shrinks as the balance shrinks and the principal barely moves. Interest keeps accruing on the remaining balance the whole time.
What is the Minimum Payment Warning box?
A CARD Act requirement: your statement must show how long the minimum-only path takes and what it costs, next to a fixed-payment alternative. It is the personalized version of this page.
Does paying more than the minimum help a lot?
Disproportionately. On $5,000 at 21%, going from minimums to $200 fixed cuts the timeline from 225 months to 34; $300 cuts it to 20. Early extra payments hit a balance generating nearly $90 of interest a month.
Does the interest rate change the timeline much?
Enormously. The same $5,000 at 12% takes 191 months at minimums vs 225 at 21%; rate is the dominant variable after payment size.
