How the Credit Card Payoff Calculator works

Credit card interest compounds on the balance you carry, so paying only the minimum can stretch a payoff over many years. This calculator shows how long it takes to clear a card and how much interest you'll pay at a given monthly payment.

Formula

Months = −log(1 − (B × i ÷ M)) ÷ log(1 + i)

B is the balance, i is the monthly rate (APR ÷ 12), and M is your fixed monthly payment. The payment M must exceed the first month's interest (B × i) or the balance never falls.

Worked example: $5,000 balance at 22% APR, paying $200/month

  1. Monthly rate i = 0.22 ÷ 12 ≈ 0.018333; balance B = 5,000; payment M = 200.
  2. B × i = 5,000 × 0.018333 ≈ $91.67 of interest in month one, so $108.33 reduces principal.
  3. Months = −log(1 − (5,000 × 0.018333 ÷ 200)) ÷ log(1.018333) ≈ 32 months.
  4. Total paid ≈ $6,300, so interest is about $1,300.

How to read the result

The gap between your payment and the monthly interest determines how fast the balance falls. Raising the payment even modestly can cut the payoff time and interest sharply, because more goes to principal every month.

Common mistakes to avoid

  • Paying only the minimum, which is mostly interest and can take a decade-plus to clear.
  • Adding new charges while paying down, which resets your progress.
  • Setting a payment below the monthly interest, so the balance never drops.

Frequently Asked Questions — Credit Card Payoff Calculator

Minimums are mostly interest plus a tiny slice of principal, so the balance barely moves. Paying a fixed higher amount clears the card far faster.
Avalanche (highest APR first) saves the most interest. Snowball (smallest balance first) gives quick wins for motivation. Both work if you stick with them.
A 0% intro offer can pause interest and speed payoff, but weigh the transfer fee (often 3–5%) and make sure you can clear the balance before the promo rate ends.
