How credit utilization is calculated

Utilization is simply total balances divided by total credit limits, expressed as a percentage. Add up what you owe across all revolving cards, divide by the sum of their limits, and multiply by 100. The calculator also tracks your worst single card, because lenders look at per-card utilization as well as the overall figure.

This ratio is one of the largest inputs to a credit score, second only to payment history. Lower is better. The bars above mark the 30% line so you can see at a glance whether you are in the healthy zone or above it.

A quick example

Say you owe $1,200 on a $5,000 card and $800 on a $3,000 card, with a third $2,000 card at zero. Total balances are $2,000 against $10,000 of limits, so overall utilization is 20%. But your second card alone sits near 27%, which is the highest single-card figure to watch.

Things to keep in mind

The balance reported to the bureaus is usually the one on your statement closing date, not the due date, so paying early can lower the number that gets recorded. For more on how scores work, see the Consumer Financial Protection Bureau. You can also model a higher limit with our credit limit increase calculator.

Frequently asked questions

What is credit utilization?

Credit utilization is the percentage of your available revolving credit that you are currently using. It is calculated as total balances divided by total credit limits. If you owe $2,000 across cards with $10,000 of limits, your utilization is 20%.

What is a good utilization ratio?

Keeping overall utilization under 30% is the common guideline, and people with the highest scores often stay under 10%. Lenders also look at your highest single card, so spreading balances out can help even if your overall ratio is low.

Does overall or per-card utilization matter more?

Both are considered. Your overall ratio across all cards carries the most weight, but a single maxed-out card can still drag your score even if the total looks fine. This calculator reports both so you can see the full picture.

How can I lower my utilization quickly?

Pay down balances before the statement closing date, since that is usually the figure reported to the bureaus. Asking for a higher limit or spreading charges across more cards also reduces the ratio, as long as you do not increase your spending.
