The Credit Cards Payoff Calculator plans several cards at once: minimums on everything, surplus on one target, and the target payment rolled onward as each card clears. It runs highest-rate-first and smallest-balance-first and compares the two.
Add each card with its balance, APR and minimum payment, then set the total you can put towards cards every month. The calculator allocates minimums across all of them and directs everything left over at one target card, then rolls that payment onward as each card clears.
Ordering the cards is the whole decision. Highest APR first minimises the interest you pay, always, and on a spread of card rates the gap against any other order can be significant. Smallest balance first clears individual cards sooner, which frees up their minimums earlier and gives visible progress. The calculator runs both and reports the debt-free date and total interest for each, so the choice is made against numbers rather than intuition.
Highest APR first always costs less; smallest balance first clears cards sooner. Both are calculated on your numbers.
The plan keeps every card current, because late fees and penalty APRs cost more than the interest saved by skipping one.
A cleared card frees its minimum for the next target, which is what makes the plan speed up.
See which card falls when, rather than only a final date.
The cost of choosing motivation over mathematics, stated as a number you can weigh.
Balance, APR and minimum payment for each card you are carrying a balance on.
The total across all cards, which must cover at least the sum of the minimums.
Highest rate first against smallest balance first, in months and in total interest.
Pay minimums everywhere, put everything spare on the target card, and roll its payment onward when it clears.
The one with the highest APR, if you want to pay the least interest. Every dollar directed at the most expensive debt saves more than the same dollar anywhere else in the plan.
To avoid late fees, penalty APRs and credit damage, which cost far more than the small amount of interest saved by skipping one. Minimums everywhere, surplus on one target.
Usually not immediately. Closing it removes available credit, which raises your utilisation ratio and can lower your score. Keeping it open with no balance is generally better for your credit.
It can be, if the promotional rate and the transfer fee together beat what you would otherwise pay, and if you can clear the balance before the promotional period ends and the rate reverts.
