What Is a Good Credit Utilization Ratio?
Published 10/13/2025 · 2 min read · Finance calculators
Credit utilization is how much of your available credit you're using — your card balance divided by your credit limit, as a percentage. Below 30% is a common guideline, and under 10% is even better for your credit score. Owe $300 on a $1,000 limit and your utilization is 30%. It's one of the biggest single factors in a credit score.
Credit utilization is the share of your credit limit you're using. Here's what counts as good, why it matters for your score, and how to lower it.
How it's calculated
Divide the balance you owe by your credit limit and multiply by 100. A $450 balance on a $1,500 limit is 450 ÷ 1,500 × 100 = 30%. Lenders look at this per card and across all your cards combined, so both a single maxed-out card and a high overall total can weigh on your score.
Why it matters
Utilization is one of the heaviest ingredients in a credit score, second only to payment history in many models. High usage signals to lenders that you may be stretched, even if you pay in full every month. Because it updates as your balances move, it is also one of the fastest levers you can pull to change your score.
The 30% and 10% guideline
The widely repeated advice is to keep utilization below 30%, and going under 10% tends to help the score further. What counts is usually the balance reported to the credit bureaus, which is often your statement balance — not necessarily what you owe today. So even if you clear the card each month, a high statement balance can still be recorded.
How to lower it
Pay down balances before the statement closes so a smaller figure is reported. Asking for a higher credit limit lowers utilization instantly if your spending stays the same, and spreading charges across cards keeps any single one from spiking. Keeping old cards open preserves your total available credit — closing one can quietly raise your ratio.

- Does 0% utilization hurt my score?
- Slightly. Reporting a small balance of a few percent can score marginally better than reporting exactly zero across all cards.
- Is utilization per card or overall?
- Both matter. Scores consider your overall ratio across all cards and the utilization of your most-used single card.
- Does paying before the statement date help?
- Yes. The balance reported is usually the statement balance, so paying it down beforehand lowers the utilization the bureaus see.
