Why minimums are a trap

The minimum payment is designed to keep you in debt.

It scales with your balance

Most issuers calculate the minimum as 1–3% of your current balance plus interest. As you pay down, the minimum drops too — so each month a smaller share goes to principal.

Interest eats most of it

On a high-APR card, most of the minimum is just covering this month's interest. Only the leftover knocks down principal — sometimes only a few dollars per month.

A small bump changes everything

Adding $50–$100 above the minimum can cut years off your payoff and save thousands in interest, because every extra dollar goes straight to principal.

Combine with a 0% APR window

If you can move the balance to a 0% APR card, every payment goes to principal for the length of the promo. Pair that with our balance-transfer tools below.
