Credit Utilization: How Much of Your Limit Should You Use?
Your credit utilization ratio is how much of your available credit card limit you're using, shown as a percentage. A common guideline is to keep it under 30%, and people with the highest credit scores typically use under 10%. It's one of the biggest factors in most credit scores, and unlike payment history, it can improve quickly.
How it's calculated
Utilization = total card balances ÷ total card limits × 100
Say you have two cards:
| Card | Balance | Limit | Utilization |
|---|---|---|---|
| Card A | $2,000 | $5,000 | 40% |
| Card B | $600 | $3,000 | 20% |
| Overall | $2,600 | $8,000 | 32.5% |
Scoring models look at both your overall utilization and each individual card. A single maxed-out card can hurt even if your overall figure is fine.
Why it matters so much
FICO says "amounts owed" makes up about 30% of a typical FICO score, and utilization is a big part of that. High utilization suggests you may be relying on credit, which lenders see as higher risk. The good news: in most traditional scoring models, utilization has no long memory. Pay balances down and your score can bounce back within a month or two. Some newer models look at trends over time, so consistently lower balances help most.
The statement-date trick
Card issuers usually report your balance to the credit bureaus around your statement date, not your payment due date. So even if you pay in full every month, a large balance on the statement can show high utilization. If you're about to apply for a mortgage or loan, pay the card down before the statement closes so a lower balance gets reported.
Ways to lower your utilization
- Pay down balances. The most direct fix. The credit card payoff calculator shows how quickly different payments clear a card.
- Pay more than once a month. Paying mid-cycle keeps the reported balance lower.
- Ask for a higher limit. If your income has risen, a limit increase lowers utilization, as long as you don't spend more. Ask whether it triggers a hard inquiry.
- Keep old cards open. Closing a card removes its limit and can push utilization up. If there's no annual fee, it's often better to keep it and use it occasionally.
- Spread balances rather than maxing out one card, if you do carry a balance.
Is 0% utilization best?
Not necessarily. Showing some small, regular use that you pay off in full shows lenders you manage credit well. Having every card at zero for a long time can occasionally score slightly lower than very low but non-zero use. In practice, the difference is small; anything under 10% is excellent.
Utilization isn't everything
Paying on time is the single most important factor in your score. The length of your credit history, the mix of credit you have and how often you apply for new credit matter too. If you're carrying balances because of debt rather than timing, a clear payoff plan will help your score and your finances more than any trick.

Frequently asked questions
What is a good credit utilization ratio?
Under 30% is a common guideline, and under 10% is typical for people with the highest credit scores.
How do I calculate credit utilization?
Divide your total credit card balances by your total credit limits and multiply by 100. $2,600 of balances on $8,000 of limits is 32.5%.
Does paying off my card in full help utilization?
Yes, but what's reported is usually your statement balance. Paying before the statement date lowers the utilization the bureaus see.
Does closing a credit card hurt utilization?
It can, because you lose that card's limit, which raises your utilization if you carry balances on other cards.
