Credit Card Payoff Calculator

Use this calculator to estimate how long it may take to pay off a credit card balance. It uses your balance, APR, monthly payment, and any additional payment to model payoff month by month.

What this calculator does

The credit card payoff calculator estimates repayment time and interest cost.

It uses:

• credit card balance
• annual percentage rate
• monthly payment
• additional payment

The result shows months to payoff, total interest, and total amount paid. If your payment does not cover monthly interest, the calculator warns that payoff may not be possible.

How to use the credit card payoff calculator

Enter your current card balance, APR, and planned monthly payment. Add an additional payment if you want to pay more than the usual amount.

Use the result to decide whether your payment is enough or whether increasing it could reduce interest meaningfully.

Credit Card Payoff Formula

Monthly interest = balance x APR / 12

New balance = balance + monthly interest - payment

The calculator repeats the calculation until the balance reaches zero.

Example calculation

If:

• Balance = 5,000
• APR = 20%
• Monthly payment = 250
• Additional payment = 50

Then:

First month interest = 5,000 x 0.20 / 12 = 83.33

The first payment reduces principal by about 216.67 before the next month is calculated.

What is credit card payoff?

Credit card payoff is the process of reducing a revolving card balance to zero. Because credit card APR can be high, the interest portion can be large when payments are small.

Paying more than the minimum usually shortens the payoff time.

Interpreting your result

Compare months to payoff and total interest. If interest is high, even a modest extra payment can make the payoff plan more efficient.

When to use this calculator

Use this calculator when you want to:

• estimate payoff time
• test extra payments
• understand interest cost
• plan card repayment

Common mistakes

Common mistakes include:

• paying only the minimum
• ignoring APR changes
• adding new purchases
• underestimating interest

FAQs

Why does credit card debt take long to repay?

High APR and low minimum payments can keep balances outstanding for a long time.
