What Is Debt to Credit Ratio (Credit Utilization)?
Your debt to credit ratio (also called credit utilization) is the percentage of your available credit that you’re currently using. It’s one of the most important factors in your credit score.
The Formula:
Credit Utilization = (Total Debt ÷ Total Credit Limit) × 100
For example, if you have $5,000 in debt and a $20,000 total credit limit, your utilization is:
Credit Utilization = ($5,000 ÷ $20,000) × 100 = 25%
Utilization Categories & Impact
| Utilization | Category | Impact on Credit Score |
|---|---|---|
| 0 – 10% | Excellent | Positive impact — ideal for credit scores |
| 11 – 30% | Good | Neutral to slightly positive |
| 31 – 50% | Fair | Negative impact starting |
| 51 – 75% | Poor | Significant negative impact |
