Credit card payoff calculator

See how long a credit card balance takes to clear at the payment you make now, what the interest costs, and what to pay each month to be done by a date you choose.

How it works

The math behind the result

Card interest is charged monthly on the balance at APR ÷ 12. A payment first covers that month’s interest, and only the rest reduces the balance, so a payment barely above the interest takes years and a payment well above it takes months.

With a set payment, the calculator runs the balance forward month by month until it reaches zero. With a payoff date, it sizes the payment with the amortization formula so the balance lands on zero in exactly that many months.

Every extra dollar goes to the balance and stops earning interest for the card, which is why raising the payment even modestly shortens the payoff more than the arithmetic suggests. New purchases are not modeled; pausing them is part of any payoff plan.

interest = balance × APR ÷ 12
balance = balance + interest − payment, month after month, until zero
payment for a date = B × r ÷ (1 − (1 + r)^−n)
