Utilization is your card balances divided by your limits, and it's part of 30% of your FICO Score. Keep it under 30%, ideally under 10%. Pay before statements close, and keep unused cards open and active to protect your limits.

If payment history is the most important part of your credit score, credit utilization is a close second. It's also one of the fastest factors to change, which makes it one of the most useful to understand.
Here's what credit utilization ratio means, how to calculate it, what counts as a good ratio, and practical ways to lower it, including one that people often overlook.
What is a credit utilization ratio?
Your credit utilization ratio is the share of your available revolving credit that you're using. It's usually calculated two ways:
- Overall utilization: total balances on all your cards divided by total credit limits.
- Per-card utilization: each card's balance divided by that card's limit.
Utilization falls under the "amounts owed" category, which makes up about 30% of a FICO® Score according to myFICO. Only payment history, at 35%, counts more.
How to calculate your credit utilization
Add up the balances on all your credit cards, add up all your credit limits, divide, and multiply by 100.
| Card | Balance | Limit | Per-card utilization |
|---|---|---|---|
| Card A | $900 | $3,000 | 30% |
| Card B | $300 | $5,000 | 6% |
| Card C | $0 | $2,000 | 0% |
| Total | $1,200 | $10,000 | 12% overall |
One important detail: the balance that usually gets reported is the one on your statement, not what you owe after paying. So even if you pay in full every month, a large statement balance can still show high utilization.
What is a good credit utilization ratio?
Experts commonly recommend keeping utilization below 30%, and Experian notes that below 10% is best for scores. In general, lower is better, though having a small balance reported can be better than showing no card activity at all.
| Utilization | What it generally signals |
|---|---|
| Under 10% | Excellent |
| 10% to 29% | Good |
| 30% to 49% | Fair; may start to weigh on scores |
| 50% and up | High; likely hurting your score |
Because utilization is based on current balances, it has no long-term memory in most scoring models. Bring your balances down, and your score can recover as soon as the lower balances are reported.
7 ways to lower your credit utilization
1. Pay down balances
The most direct method. Focus on cards with the highest per-card utilization first.
2. Pay before your statement closes
Making a payment before the statement closing date lowers the balance that gets reported, even if you'd pay in full anyway.
3. Make multiple payments a month
If you use a card heavily, paying it down every week or two keeps the reported balance low.
4. Spread spending across cards
Instead of putting everything on one card and pushing it to 60%, spread purchases so no single card runs high.
5. Ask for a credit limit increase
A higher limit lowers your ratio without changing your spending. Ask your issuer whether the request involves a hard inquiry.
6. Don't close unused cards
Closing a card removes its limit from the calculation, which can raise your utilization overnight. See Does Closing a Credit Card Hurt Your Credit?
7. Keep every card active so the bank doesn't close it
This is the one people overlook. You can protect your utilization perfectly and still lose ground if an issuer closes an unused card for inactivity, often without warning. Learn why in Credit Card Closed Due to Inactivity?
The easy fix is a tiny, regular charge on each card. Credicated does it automatically: Platinum at $0.99 a month, Gold at $1.25 every 3 months, or Silver at $1.25 a year. The charges are so small they barely move your utilization, but they keep each card's full limit working for you. Pair it with autopay, and every card stays open and paid on time.
Common credit utilization myths
- "Carrying a balance helps your score." False. You don't need to pay interest to build credit. Pay your statement balance in full.
- "0% utilization is perfect." Not necessarily. Some scoring models may reward a small reported balance over no activity at all. A tiny charge paid in full gives you both.
- "Utilization damage lasts for years." In most scoring models, it updates as new balances are reported.
Frequently asked questions
What is a good credit utilization ratio?
Below 30% is a common guideline, and below 10% is generally best for scores.
Does credit utilization affect my score right away?
It changes as your issuers report new balances, usually once a month around your statement date.
Is utilization calculated per card or overall?
Both can matter. Scoring models consider your overall ratio and individual card ratios, so avoid maxing out any single card.
How does closing a credit card affect utilization?
It removes that card's limit, so the same balances make up a larger share of your remaining credit, which raises your ratio.
