How much does credit utilization affect your score?

Credit utilization is about 30% of your FICO score — second only to payment history. Keeping your balances under 30% of your limits helps, and under 10% is ideal. High utilization can cost dozens of points, and because it updates every statement, it's one of the fastest factors you can improve.

Short answer: Credit utilization is a major score factor and one of the fastest legitimate levers before a mortgage, refinance, or rate-shopping window. Paying balances before the statement date can lower reported utilization and may help the next score update. If utilization is only one part of the issue, use a Credit Diagnosis to separate quick score levers from reporting disputes.

How it works

Utilization is your revolving balances divided by your limits, measured both per-card and overall. The score generally responds to the balance reported on your statement — so paying down before the statement cuts can lower your reported utilization and lift your score on the next update.

Why it's the fastest lever

Unlike payment history (which takes time to rebuild), utilization has no memory — lower it this month and your score can rise next month. That's why it's the go-to move before a mortgage application or rate-shopping.
