What is credit utilization?

Credit utilization is the percentage of your total available revolving credit that you are currently using. It is calculated by dividing your total balances by your total credit limits.

What credit utilization is ideal?

Most financial experts recommend keeping utilization below 30%, and ideally below 10%, for the best impact on your credit score. Utilization is the second-most important factor in your FICO score, accounting for 30%.

How quickly does utilization affect my credit score?

Credit utilization changes can affect your score within 30 days, as soon as your card issuer reports your new balance to the credit bureaus. It is one of the fastest factors you can change.

Why Credit Utilization Matters

Credit utilization is the second most important factor in your FICO credit score, accounting for approximately 30% of the total calculation. It measures how much of your available revolving credit you are currently using. Understanding and actively managing this percentage can lead to significant and rapid improvements in your creditworthiness and borrowing power.

The 30% Rule vs. The 10% Target

The widely-cited financial rule of thumb is to keep your overall credit utilization below 30% across all your cards. However, empirical research shows that consumers with the highest credit scores (over 800) typically maintain a utilization rate well below 10%. The ideal target is to keep your balances as low as possible while still demonstrating that you use your cards responsibly.

Two Powerful Ways to Reduce Utilization

You can lower your credit utilization ratio in two ways: by paying down your existing balances or by increasing your total available credit limit. Requesting a credit limit increase on an existing card (often done online without a hard credit pull) can instantly improve your utilization ratio, provided you do not use the newly available credit to increase your spending.
