How to Calculate Credit Card Calculator
What is Credit Card Calculator?
A credit card payoff calculator shows how long it will take to eliminate a credit card balance given your monthly payment, or what payment is needed to be debt-free by a specific date. Credit cards compound interest daily, making high-APR balances extremely costly to carry.
Step-by-Step Guide
- 1Identify your balance, APR (annual percentage rate), and monthly payment
- 2Monthly interest rate = APR ÷ 12
- 3Each month: interest accrues on remaining balance, then payment is applied
- 4Payoff time = number of months until balance reaches zero
- 5Total interest = (monthly payment × number of months) − original balance
