Quick answer: Credit utilization compares revolving credit balances with revolving credit limits. It is one factor commonly used in credit-scoring models.
How to calculate credit utilization
Divide a revolving balance by its credit limit and multiply by 100. A $500 reported balance on a $2,000 limit is 25% utilization.
Overall vs. per-card utilization
Scoring models may consider utilization across revolving accounts as well as individual accounts. That means one heavily used card can matter even when your total available credit is much larger.
Statement balance is not always the reported balance
Card issuers typically report account information periodically. The balance appearing on a credit report may not match what you owe at this exact moment. Paying in full by the due date and managing reported utilization are related but different ideas.
Is there a magic utilization percentage?
Avoid treating a single percentage as a universal cliff. Scoring models differ, and utilization is only one part of a score. In general, lower revolving utilization indicates less reliance on available revolving credit, but carrying interest-bearing debt just to build credit is unnecessary.
Next steps
See the credit score guide, learn statement vs. current balance, and review how credit-card interest works.
Sources and verification
For current consumer-credit information, use primary resources from the Consumer Financial Protection Bureau, Federal Trade Commission, and federally authorized credit-report sources. Card-specific rates, fees, grace periods, and reporting practices should be verified with the issuer.
