Credit Card Minimum Payments: The Math That Keeps You in Debt
The minimum payment on a credit card is not designed to help you escape debt — it is designed to keep the account profitable for as long as possible. The math is unforgiving: on a $5,000 balance at 18% APR, a 2% minimum takes 31 years and costs $12,328 in interest. Here is why, and how to get out faster.
How the minimum is calculated
Most cards set the minimum as the larger of 1–2% of the balance or a flat floor of $25–$35. The interest is charged on top of that, so early in the loan most of your minimum payment is pure interest.
The worked math
Take $5,000 at 18% APR with a 2% minimum:
| Item | Amount |
|---|---|
| Monthly interest | $75 |
| Minimum payment | $100 |
| Principal reduction | $25 |
| Time to pay off | ~31 years |
| Total interest | $12,328 |
Three-quarters of your first payment is interest. The minimum payment calculator shows your exact numbers — and flags the worst case, where the minimum doesn’t even cover the interest and the debt grows forever.
What if the minimum doesn't cover the interest?
It happens more than you would think: a 1% minimum on a 24% APR balance never pays off, because $50 against $100 of monthly interest makes the balance grow. The account stays current (your credit score survives) but you are slowly paying to stay in debt.
The three ways out
- Pay a fixed amount above the interest. Even $150 instead of $100 on the example above cuts decades off the payoff. The credit card payoff calculator shows the schedule.
- Order debts by rate or by size. The snowball vs avalanche guide explains why both methods work and how to pick.
- Transfer to a 0% balance card. A 0% window with a transfer fee is usually worth it if you can pay the balance down inside the window.
The minimum payment myth
Paying the minimum protects your credit score, but it does nothing for your finances — the score rewards on-time payment, not slow repayment. The mathematically optimal move for both score and wallet is the same: pay as much above the minimum as you can, ideally the full statement balance every month.
