About Credit Card Payoff Time Calculator

Card interest compounds monthly at a rate near 3%, so the payoff time depends sharply on how far the payment exceeds the interest charge. Anything close to the minimum leaves the balance almost untouched for years.

Formula

Payoff months

n = -ln(1 - B·r/payment) / ln(1 + r)

B
Balance
r
Monthly rate = APR/12

Frequently Asked Questions

Why do minimum payments take so long?

A minimum is usually just above the interest charge, so only a sliver goes to principal each month.

Does paying twice a month help?

Slightly, because average daily balance falls. The bigger lever is simply paying more.
