Credit Utilization Ratio Calculator

Understand Your Credit Use. Protect Your Score.

Your credit utilization ratio is one of the most important factors in your credit score—and yet, it’s one of the easiest to improve. Our free Credit Utilization Ratio Calculator helps you see exactly how much of your credit you’re using and whether you’re in a healthy range.

Whether you have one credit card or five, this tool gives you an accurate picture of your overall usage, plus the utilization rate of each individual card. That’s key, because using too much of your available credit—even on just one card—can drag your score down.

What Is Credit Utilization?

Credit utilization is the percentage of your total available credit that you’re currently using. For example, if you have a $5,000 total credit limit and carry a $2,000 balance, your utilization is 40%. The lower your percentage, the better it looks to credit bureaus.
