Every extra dollar above the minimum goes straight to principal, cutting both the payoff time and the interest you pay.
How it works
Monthly: interest = balance × (APR ÷ 12), balance = balance + interest − payment. Count months until zero.
Example: $8,000 at 19.99% → minimum takes ~21 years; $300/month clears it in ~3.5 years and saves ~$12,000.

Frequently Asked Questions
How long does it take to pay off a credit card?
At the minimum payment alone, an $8,000 balance at 20% APR can take 20+ years and cost more than double in interest. This calculator shows your payoff date at any payment amount.
How much interest will I save by paying more than the minimum?
Every extra dollar shortens the payoff and cuts interest. Doubling the minimum payment can save thousands and finish the debt years sooner — the calculator quantifies exactly how much.
What is the debt avalanche vs snowball for credit cards?
Avalanche pays off the highest-APR card first (cheapest overall); snowball pays off the smallest balance first (motivating). Both work — pick what you'll stick with.
Is this credit card payoff calculator free to use?
Yes, True Calculator's credit card payoff calculator is completely free with no sign-up, no app install and no usage limits.
