Credit utilization is how much of your available credit card limits you’re using. It falls under amounts owed, about 30% of your FICO Score, and most experts suggest keeping it below 30%.
If your credit score isn’t where you want it to be, your credit utilization ratio could be a key reason why. It’s one of the most influential factors in your score, and one of the most overlooked.
This guide breaks down what credit utilization is, how it affects your score, how to calculate it, and which strategies may help bring it down.

Credit utilization is how much of your available revolving credit you’re using. It’s your credit card balances divided by your credit limits, shown as a percentage.
For example, if you have one credit card with a $10,000 limit and a current balance of $3,000, your utilization on that card is 30%. Scoring models look at each card and at your overall utilization across all cards combined.
A high utilization rate may signal to lenders that you are over-reliant on credit, which can affect both your score and your ability to access new credit on favorable terms. For a closer look at how this ratio is defined, the Consumer Financial Protection Bureau’s credit resources offer a helpful foundation.
Credit utilization is one of the heaviest-weighted factors in most scoring models. In FICO scoring, it falls under amounts owed, which makes up about 30% of your score, second only to payment history.
Here’s how the impact breaks down:
Errors on your credit report, such as a balance reported incorrectly or a payment misapplied, can make your utilization look higher than it is. In a 2013 FTC study of credit report accuracy, one in four consumers identified errors on their credit reports that might affect their credit scores.
Calculating your ratio is straightforward. Follow these three steps:
Example:
Total balances: $1,500. Total limits: $10,000. Utilization ratio: 15%.
Credit bureaus generally receive updated balance and limit information once per billing cycle. That means paying down balances before your statement closes may result in a lower utilization figure being reported.
If your utilization is higher than you’d like, several strategies may help bring it down over time:
One factor that is sometimes missed: reporting inaccuracies. If a balance on your report is listed higher than it actually is, or a payment was applied incorrectly, your utilization will look worse than it should.
You can dispute the error with the credit bureau that lists it. A credit repair review may help identify those kinds of issues.
Credit utilization is one of the most influential parts of your score, and one of the easiest to change. Most experts suggest staying below 30%. Paying down balances, paying before your statement closes and keeping old accounts open can help, and so can checking your reports for balances reported incorrectly.
