A Credit Utilization Ratio Calculator helps you determine how much of your available revolving credit you’re currently using. Credit utilization is one of the most important factors that affects your credit score, accounting for roughly 30% of your FICO® Score.
The calculator compares your total credit card balances with your total credit limits and shows your utilization percentage.

Credit Utilization Formula
Credit Utilization Ratio = (Total Credit Card Balance ÷ Total Credit Limit) × 100
Example
Suppose you have:
- Total Credit Limit: $12,000
- Total Credit Card Balance: $2,400
Calculation:
($2,400 ÷ $12,000) × 100 = 20%
Your credit utilization ratio is 20%, which is generally considered good.
What Your Utilization Means
| Credit Utilization | Rating | Impact on Credit Score |
|---|---|---|
| 0–10% | Excellent | Best for maximizing your score |
| 11–30% | Good | Healthy credit usage |
| 31–50% | Fair | May lower your score slightly |
| 51–75% | Poor | Significant negative impact |
| Above 75% | Very Poor | High risk to lenders |
How to Improve Your Credit Utilization
- Pay down credit card balances before the statement closing date.
- Keep utilization below 30%, and ideally below 10%.
- Request a higher credit limit if appropriate.
- Avoid closing old credit card accounts.
- Spread balances across multiple cards instead of maxing out one card.
- Pay your balances multiple times during the month if needed.
