Credit Card Payoff Calculator

Credit card debt is one of the most expensive forms of debt because interest compounds monthly on your remaining balance. The average credit card APR in the United States ranges from 15% to 25%, which means carrying a balance can quickly become overwhelming. Understanding how long it takes to pay off and how much interest you will pay is the first step toward becoming debt-free.

The math: Each month, interest is calculated as: Interest = Balance × (APR ÷ 12). Your payment first covers this interest, and whatever remains reduces the principal. The next month's interest is calculated on the smaller balance. This continues until the balance reaches zero. If your payment is less than the monthly interest, the balance grows even with payments.

Minimum payment trap: Credit card minimum payments are typically 2-3% of the balance. At this rate, it can take 10-20 years to pay off a card and you will pay more in interest than the original purchase. Increasing your payment even slightly has a dramatic effect on payoff time.

Payoff strategies: The debt snowball method focuses on paying off the smallest balance first for psychological wins. The debt avalanche method targets the highest-interest debt first to minimize total interest. Both methods involve making minimum payments on all cards while putting extra money toward the targeted card.

The power of extra payments: Adding just $25-50 per month above your minimum payment can shave years off your payoff timeline and save hundreds or thousands in interest. This is because every extra dollar goes directly to reducing principal, which compounds the benefit in subsequent months.
