See how long it takes to pay off your credit card, compare payment strategies, and find your debt-free date.
A credit card payoff calculator estimates how long it takes to eliminate your credit card balance and how much total interest you'll pay based on your monthly payment amount. It uses the formula n = −log(1 − r × B / P) / log(1 + r), where B is balance, r is monthly interest rate, and P is monthly payment. For example, a $5,000 balance at 20% APR with $200/month payments takes about 2 years 11 months to pay off, costing $1,873 in interest.
