How this credit card payoff calculator works

This calculator estimates how long it will take to pay off a credit card balance using your APR and payment amount. It also shows how much interest you may pay and how much faster you could get out of debt by adding extra monthly payments.

You can choose between a fixed monthly payment, an estimated minimum payment, or a target payoff time. That makes it easier to compare different repayment strategies.

What does this calculator show?

Payoff time: How long it may take to eliminate the credit card balance
Total interest: Interest paid over the repayment period
Total paid: Principal plus total interest
Interest saved: Reduction in interest from extra monthly payments

Common uses

Credit card payoff formulas

The calculator uses standard monthly compounding formulas:

Monthly Interest Rate = APR ÷ 12 Interest Each Month = Current Balance × Monthly Interest Rate Principal Paid = Monthly Payment − Monthly Interest New Balance = Current Balance − Principal Paid Estimated Minimum Payment = max(Balance × Minimum Payment Rate, Minimum Payment Floor) Target Payment (amortized payoff) = P × [ r(1 + r)^n ] ÷ [ (1 + r)^n − 1 ]

Example

If your balance is $8,000, your APR is 22.99%, and your monthly payment is $250, the calculator estimates how long payoff may take and how much interest you could pay along the way.

Credit Card Payoff Calculator FAQ

What is the difference between APR and interest rate?

APR is the annual percentage rate on the card balance. This calculator converts APR into a monthly rate to estimate interest charges over time.

Why do minimum payments take so long?

Minimum payments are often small relative to the balance, so more of each payment goes toward interest and less goes toward principal, especially at high APRs.

Does an extra payment really help that much?

Yes. Even a modest extra monthly payment can reduce interest costs and shorten payoff time significantly.

Can payoff become impossible?

Yes. If the payment does not cover monthly interest, the balance will not go down. The calculator will show that payoff is not possible in that case.

Is the minimum payment exact?

No. This calculator uses an estimate based on a percentage of balance and a payment floor. Your actual card issuer may use a different formula.
