Credit Card Payoff Calculator

A card is not a loan with an end date. A car loan or a mortgage has a fixed payment and a final month written into the contract. A credit card has neither. There is only a balance, a rate, and a minimum the issuer recalculates every statement — which means the card has no payoff date until you decide what you are paying each month.

The minimum is designed to shrink. Most issuers ask for roughly 1% of the balance plus the interest that accrued, floored at about $25. As the balance falls, so does the amount due, so the principal you retire gets smaller every single month. That single feature is what turns a few thousand dollars into a two-decade balance.

A fixed payment breaks the pattern. Pay the same dollar amount every month rather than whatever the statement asks for, and the interest portion shrinks while the principal portion grows. Nothing about the card changes — you have simply stopped letting the payoff decelerate.

Take a $6,000 balance at 22% APR with no new purchases. The first month's interest alone is $110. Here is what four different approaches to that identical balance produce:

The first two rows are worth comparing carefully. The minimum starts at $170 — only $30 less than the fixed $200 plan — yet it costs an extra $7,142 in interest and takes seventeen more years. Almost none of that gap comes from the size of the first payment. It comes from what happens to every payment after it: the minimum falls to $152 by month 12 and $94 by month 60, while the fixed $200 never moves.

Card debt usually outranks everything except a 401(k) match. At 22%, every dollar you put against the balance earns a guaranteed 22% return. No investment offers that with certainty, and no mortgage or car loan you hold costs nearly as much. The common exception is an employer match, which is an instant 50–100% return and should be captured first.

Keep a small cash buffer anyway. Emptying your savings into the card and then meeting the next emergency with the same card leaves you exactly where you started, minus the buffer. A modest starter fund — often a month's essential expenses — is what stops the balance from rebuilding.

Consider a transfer or a fixed-rate loan only if the payment stays put. A 0% balance transfer or a consolidation loan lowers the rate, not the discipline required. Both work when you keep paying the amount that clears the balance inside the promotional window or the loan term; both fail when the lower payment becomes the new habit and the card fills back up.

This page models one card at a time. If you are carrying balances across several cards, the ordering question matters more than the arithmetic on any single one — work through them with the debt snowball calculator, which also runs the avalanche method for comparison.
