Credit Card Debt Calculator
Last updated
The credit card payoff calculator computes the time and total interest needed to clear revolving card debt. A $6,000 balance at 22% APR paid at $150 monthly takes 73 months and costs $4,913.45 in interest. Increasing the payment to $300 monthly pays off the debt in 26 months, saving $3,370.58 in finance charges.
Calculate how long it will take to pay off your credit card debt and how much interest you will pay.

How Does Revolving Credit Card Interest Compound Over Time?
Pick ₹, $, € or £ in the calculator — it changes the symbol and number format, not the amounts.
The True Cost of Low Payments: Minimum payments set by card issuers are often calculated as a small percentage of the balance plus finance charges, which can significantly lengthen payoff times. Because finance charges consume most of each early installment, principal reduction is minimal unless you commit extra funds.

The Critical Payment Floor: If your monthly payment is less than or equal to the monthly interest accrued (
Payment ≤ Balance × APR / 12), the balance will never decrease. The calculator actively detects this condition, issuing a warning when payment levels are insufficient to cover ongoing finance charges.Worked Example:
1. Credit Card Balance: $6,000 at 22% APR.
2. First Month Breakdown: Monthly interest rate is 1.833% (22% / 12). The first month interest charge is exactly $110.00, meaning a $150 payment sends only $40.00 toward reducing principal.
3. Scenario A ($150/month payment): Takes 73 months to pay off, incurring $4,913.45 in total interest (Total repaid: $10,913.45).
4. Scenario B ($300/month payment): Payoff time drops to 26 months, cutting total interest to $1,542.87 (Total repaid: $7,542.87).
5. Net Savings: Increasing the payment to $300/month saves $3,370.58 in interest and clears the debt 47 months sooner.
The Credit Card Payoff Calculator calculates how long it will take to eliminate credit card balances and how much interest you will pay using a monthly rate (APR / 12), demonstrating how higher monthly payments save thousands.
Definition: Credit Card Monthly Amortization
The process of reducing revolving credit card debt through monthly payments, where monthly finance charges equal Balance × (APR / 12) and the remainder of each payment reduces the principal.

Frequently Asked Questions
Does this calculator use daily or monthly compounding?
The calculator uses a monthly periodic rate: APR / 12. While banks calculate finance charges using daily balances, monthly rate calculation provides an accurate schedule for planning payment amounts.
What should I do if my payment amount shows an 'Infinite Payoff' warning?
If your monthly payment is less than or equal to monthly interest charges (Balance × APR / 12), your balance will never decrease. You must increase your payment above the monthly interest threshold to reduce principal.
Does paying off card balances faster improve credit scores?
Yes. Reducing revolving balances lowers your credit utilization ratio (balance divided by credit limit), which is a key factor in standard credit scoring models.
