Credit Card Payment Calculator

Pick the date you want to be debt-free and this credit card payment calculator tells you exactly what to pay each month — plus the total interest you will pay along the way.

Your payoff target
payment = r·balance ÷ (1 − (1+r)⁻ⁿ), with r = APR ÷ 12

How the credit card payment calculator works

While the payoff calculator starts from a fixed payment and finds the date, this credit card payment calculator works the other way: you set the deadline — 12, 24, or 36 months — and it solves for the fixed monthly payment that clears the balance exactly on time, using the standard loan amortization formula.

Try a shorter timeframe to see how much interest you save. Cutting a payoff plan from 36 months to 24 months usually saves a large share of the total interest, because less time means less compounding working against you.

P = r·B / (1 − (1+r)⁻ⁿ) · total interest = P·n − B

Credit card payment calculator FAQ

What is the difference between this and the payoff calculator?

The payoff calculator takes a payment amount and tells you how long repayment takes. This one takes your target timeframe and tells you the payment needed — use whichever direction matches your planning.

How much faster is a 24-month plan than a 36-month plan?

Enter both timeframes and compare the total interest rows. The shorter plan almost always saves a big chunk of interest, though the monthly payment is higher.

Does the payment stay the same every month?

Yes — the calculated payment is fixed. Your last payment may be slightly smaller since the balance will not divide perfectly.

What if the required payment is more than I can afford?

Lengthen the timeframe a little and recalculate. Even a few extra months lowers the payment; just watch the total interest climb.

Are balance-transfer offers worth it?

A 0% introductory APR for 12–18 months can save a lot of interest — but factor in the typical 3–5% transfer fee before deciding.
