Credit utilization is the share of your available credit that you are actually using, written as a percentage.

The math is simple. Take what you owe on your credit cards, divide it by your total credit limits, and that is your utilization. If you owe $500 on a card with a $2,000 limit, you are using 25%. Lenders look at this both card by card and across all your cards added together.

It matters because utilization is one of the biggest pieces of your credit score, second only to paying on time. A high number signals that you may be leaning hard on credit, which makes lenders nervous. A low number tells them you have room to spare and you are in control. Most guidance points to keeping it under 30%, and under 10% is even better.

Here is a real example. Say you have two cards with a combined limit of $10,000. If your balances add up to $4,000, your utilization is 40%, high enough to drag your score down. Pay that down to $1,000 and you drop to 10%, which can lift your score noticeably within a statement cycle or two. Nothing changed about your income. You just used less of the line.

One quiet trick: utilization is usually measured on the date your statement closes, not the due date. So paying down the balance a few days before the statement cuts can lower the number the lender reports, even if you were going to pay it off anyway.

Bottom line: keep your balances low compared to your limits, ideally under 30%, and your credit score will thank you for it. This is general education, not personalized advice.
