Credit Card Calculator — Payoff Time & Required Payment

Stop guessing how long it will take to clear your credit card debt. Our Credit Card Calculator runs a precise month-by-month simulation to show you exactly when you'll be debt-free — and exactly how much interest you'll pay along the way.

Two Powerful Calculation Modes

1. Time to Pay Off

Enter your current balance, APR, and monthly payment to instantly discover:

• Exact months until the balance reaches zero
• Projected payoff date (month and year)
• Total interest you'll pay over the life of the debt
• Interest ratio — the percentage of your total payments that goes to interest (not principal)

This mode supports both minimum payment as a % of balance (the standard credit card method) and a fixed dollar minimum, plus an extra monthly payment field to model accelerated payoff scenarios.

2. Payment to Pay Off In Time

Have a target deadline? Enter the number of months you want to be debt-free and the calculator solves for the exact monthly payment required — no trial and error.

Why Minimum-Only Payments Are Dangerous

When you only pay the minimum (typically 2% of the balance), credit card debt can last decades. For example:

The difference is stark. Our calculator makes this immediately visible through the interactive Balance vs. Cumulative Interest chart.

Key Features

• Month-by-month simulation engine for precise results (not approximations)
• Flexible minimum payment — set as a % of balance or a fixed amount
• Extra payment field to model additional contributions
• Dual-dataset chart showing how your balance falls and interest accumulates over time
• Payoff date projection in month/year format
• Data persistence — your settings survive page reloads

Disclaimer: Calculations assume a fixed APR with no new purchases, fees, or balance transfers. Results are estimates only.
