What is the 30% Credit Utilization Rule?

The 30% credit card utilization ratio is the percentage of your total available credit that you are currently using. It is calculated by dividing your total credit card balances by your total credit limits across all cards.

Financial experts often recommend keeping your utilization ratio below 30%. This means using no more than 30% of your total available credit at any given time. The 30% utilization rule exists because credit scoring models consider high utilization to be a sign of credit risk. The higher your ratio, the more it can negatively impact your credit scores.

Specifically, FICO and VantageScore formulas take into account your credit utilization when determining your creditworthiness. High utilization can lower your credit score, while low utilization can raise it. This is because high utilization may indicate you are overextended and depend too heavily on credit cards to fund your lifestyle. Conversely, low utilization shows you are managing credit responsibly.
