What Is Credit Utilization?

Credit utilization ratio is the share of available revolving credit, such as credit card limits, that is currently being used. It is calculated as total balances divided by total credit limits, times 100. Credit scoring models commonly treat lower utilization as a sign of lower risk.

Formula

Credit utilization = total card balances ÷ total credit limits × 100. It can be measured overall and for each card separately.

Example

Balances of 1,500 on cards with combined limits of 10,000 give a utilization ratio of 15%.

How It Is Commonly Discussed

Consumer credit educators often cite utilization below about 30% as a general reference point, and note that the ratio is usually based on the balance reported to credit bureaus, which may be the statement balance rather than the balance on the day of payment.
