The minimum-payment trap: what debt actually costs you

Paying only the minimum keeps an account in good standing — it doesn't keep the real cost of the debt small.

Minimum payments are designed around cash flow, not payoff speed

A credit card or line of credit's minimum payment is calculated to keep the account current — it isn't calculated to pay the balance off in any particular amount of time. On a revolving balance at a typical consumer interest rate, paying only the minimum each month can stretch payoff time out by years, with a large share of every payment going to interest rather than the balance itself.

That's not a hidden fee or a trick — it's just how amortization works when the payment is small relative to the balance and rate. The gap between "the account is in good standing" and "this debt is actually shrinking at a reasonable pace" can be a lot bigger than it looks from the monthly statement alone.

The number that actually matters: real payoff time

The useful question isn't "can I afford the minimum payment" — it's "how long will this actually take to pay off at what I'm currently paying, and what happens to that timeline if I pay even a bit more." Small increases above the minimum often cut payoff time disproportionately, because more of each extra dollar goes straight to principal instead of interest.

Running that calculation honestly, for your real balance and real rate, is a better decision tool than eyeballing the minimum payment line on a statement.
