About the Credit Card Payoff Calculator
The credit card payoff calculator shows how long it will take to clear a card balance with a fixed monthly payment, how much interest you will pay along the way and the month you will be debt-free. Each month it adds interest at your APR divided by twelve, subtracts your payment and repeats until the balance reaches zero. If your payment does not even cover the first month’s interest, the balance can never be repaid and the tool tells you so. Trying a few payment amounts is the quickest way to see how much an extra $50 or $100 a month saves.
How to use it
- 1Enter your current card balance.
- 2Enter the card’s APR as a percentage.
- 3Enter the fixed amount you will pay each month.
- 4Press Calculate to see the months to payoff, total interest and payoff date.
- 5Increase the payment and recalculate to compare the savings.
Worked example
a $5,000 balance at 19.99% APR paid off at $200 a month takes 33 months and costs about $1,521 in interest. Raising the payment to $300 a month clears the card in 20 months and cuts interest to about $906 — a saving of more than $600.
How it works
How it works
Each month interest is added to the balance, then your payment is subtracted. The calculator repeats until the balance reaches zero.
Tip
Paying more than the minimum dramatically reduces both the time and total interest.
Who it is for
Anyone carrying a credit card balance, especially people deciding how much to pay each month or whether a balance transfer is worth it.
Why it helps
Minimum payments hide how long debt lasts; a payoff date and an interest total make the cost visible.
Common use cases
- Choosing a monthly payment that clears a card within a year
- Comparing the interest cost of paying $150, $200 or $300 a month
- Deciding whether a 0% balance transfer would save money
- Ordering several cards for an avalanche or snowball payoff plan
Frequently asked questions
A:If your payment is less than the monthly interest, the balance grows instead of shrinking.
