Credit utilization describes how much of your available revolving credit you're actually using. It's one of the most influential factors in many credit scoring models, and it's also one of the most within your control. Understanding how it works can help you build healthier credit habits over time.
Utilization is generally calculated by dividing your current balances on revolving accounts (like credit cards) by your total credit limits. For example, if you have a $1,000 limit and a $300 balance, your utilization is 30%.

Frequently asked questions
Is there a single ideal utilization percentage?
There's no universal number that applies to everyone or every scoring model. A common general guideline is to keep utilization relatively low, but the impact of any specific level depends on the rest of your credit profile and the scoring model used.
Should I carry a balance to build credit?
No. You can build credit by using your accounts and paying them in full each month. Carrying a balance isn't necessary to build credit and can lead to unnecessary interest charges.
Does requesting a limit increase hurt my credit?
Some limit increase requests result in a hard inquiry, which can have a small, temporary effect. The potential benefit of more available credit may offset that for many consumers, but it depends on your individual situation.
