At a typical 22% APR, paying $100 a month on a $5,000 balance takes about 11.4 years and costs $8,678 in interest — more than the balance itself. On bigger balances a small fixed payment never clears the card at all. This benchmark shows payoff time and interest across common balances and payments.
Each cell is the time to clear that balance at that fixed monthly payment, with the total interest paid, at a 22% APR. “Never” means the payment is at or below the monthly interest, so the balance never goes down.

Assumes a fixed 22% APR, a constant payment, and no new charges; rounded. 22% is a typical card rate (many run 18–26%) — not a specific offer. Real cards compound daily and minimum payments shrink as the balance falls, which stretches payoff even longer. Every value is reproduced by the free credit card payoff calculator.
On a high-APR card, most of a small payment goes straight to interest — only what's left chips at the balance. At 22%, each $1,000 of balance costs about $18 a month in interest alone, so a $100 payment on a $6,000 balance puts roughly $110 toward interest and only the rest toward principal. That's why paying just the minimum can take a decade, and why every extra dollar — which goes entirely to principal — compounds in your favor.
This is an original computation, not a lender quote — so every cell is verifiable. The formula solves the standard amortization equation for the number of payments, identical to our public calculator:
months to pay off = −ln(1 − Balance × r ÷ Payment) ÷ ln(1 + r) where r = APR ÷ 12 (if Payment ≤ Balance × r, it never pays off) total interest = Payment × months − Balance
Example: $5,000 at 22% with a $100 payment gives r = 0.01833, so months = 137 (~11.4 years) and interest = $8,678. Run your own balance, APR, and payment in the credit card payoff calculator.
Far longer than most people expect. At a 22% APR, $5,000 at a fixed $100/month takes about 11.4 years and $8,678 in interest — and any balance above roughly $5,455 never pays off at $100/month at all, because the payment only covers the interest.
A lot, because every extra dollar goes straight to principal. On a $5,000 balance at 22%, raising the payment from $100 to $200 a month cuts payoff from 11.4 years to 34 months and saves about $6,928 in interest.
Because if your payment is at or below the monthly interest, there's nothing left to reduce the balance. At 22% APR each $1,000 owed costs about $18/month in interest, so a payment that doesn't clear that never makes progress.
