See how long it takes to pay off a credit card or loan, the total interest you'll pay, and how much an extra monthly payment saves you — in time and money. No signup, instant results.
How long will it take to pay off a credit card? Each month, interest of balance × (APR ÷ 12) is added, then your payment is subtracted. The calculator steps month by month until the balance reaches zero, counting the months and summing the interest. Key rule: your monthly payment must exceed the first month's interest, or the balance never goes down.
Month by month: interest equal to balance × (APR ÷ 12) is added, then your payment is subtracted. The months are counted until the balance hits zero, and the interest is summed along the way.
On high-APR debt, most of a small payment goes to interest. If the payment is only slightly above the monthly interest, payoff can take many years. Paying more above the interest dramatically shortens it.
Enter an extra amount to see the difference — extra payments go straight to principal, cutting both the payoff time and total interest. The savings box shows the months and dollars saved.
If your monthly payment is less than or equal to the first month's interest, the balance never decreases — the tool will warn you to increase the payment.
