Key takeaways
- Credit utilization is the percentage of your available revolving credit that you’re using. It’s a major part of the “amounts owed” category, about 30% of a FICO Score.
- Calculate it overall (all cards combined) and per card. Both can affect your score.
- Lower is better. Below 30% is a common guideline; people with the highest scores often keep utilization below 10%.
- Most scoring models look at the balance on your statement, so paying before the statement closing date can lower reported utilization quickly.
- Utilization has no long-term memory in most scoring models. Once lower balances are reported, your score can improve within a billing cycle or two.
You pay your credit cards on time every month, yet your credit score isn’t where you expect it to be. One common reason: high credit utilization.
Utilization is one of the most powerful levers in your credit score, and one of the fastest to change. This guide explains how to calculate it, what’s considered good, and practical ways to lower it.
What is credit utilization?
Credit utilization (also called the credit utilization ratio) measures how much of your revolving credit you’re using.
Credit utilization = Total revolving balances ÷ Total revolving credit limits × 100
Revolving credit includes credit cards and lines of credit. Installment loans, such as car loans, student loans and mortgages, generally aren’t part of the revolving utilization calculation, although scoring models do consider how much you still owe on installment loans compared with the original amounts.
How much it matters
For FICO Scores, the “amounts owed” category accounts for about 30% of your score, second only to payment history (35%). Revolving utilization is a key part of that category. VantageScore models also weigh utilization heavily.
How to calculate overall utilization
Example: Morgan has three credit cards.
| Card | Balance | Credit limit |
|---|---|---|
| Card A | $1,500 | $3,000 |
| Card B | $800 | $5,000 |
| Card C | $200 | $2,000 |
| Total | $2,500 | $10,000 |
Overall utilization = $2,500 ÷ $10,000 = 25%
How to calculate per-card utilization
Scoring models may also consider utilization on individual cards.
| Card | Balance | Limit | Utilization |
|---|---|---|---|
| Card A | $1,500 | $3,000 | 50% |
| Card B | $800 | $5,000 | 16% |
| Card C | $200 | $2,000 | 10% |
Morgan’s overall utilization is 25%, but Card A is at 50%. Paying down Card A first could have an outsized effect on Morgan’s score.
What’s a good credit utilization ratio?
| Utilization | General effect |
|---|---|
| 0% | Not always best; some models reward showing a small balance |
| 1% to 9% | Associated with excellent scores |
| 10% to 29% | Good |
| 30% to 49% | May begin to weigh on scores |
| 50% to 74% | Likely to lower scores noticeably |
| 75% or higher | Significant negative impact |
These are general patterns, not exact cutoffs. Each scoring model calculates differently.
When utilization is reported
Most card issuers report your balance to the credit bureaus once a month, usually around your statement closing date, not your payment due date. That means:
- If you charge $2,000 during the month and pay it in full by the due date, the bureaus may still see a $2,000 balance if it was reported at statement closing.
- Paying before the statement closes lowers the balance that gets reported.
This is why people who pay in full every month can still show high utilization.
7 ways to lower credit utilization
1. Pay down balances
The most direct approach. Target cards with the highest per-card utilization first if your goal is a quick score boost, or the highest interest rate if your goal is saving money.
2. Pay before the statement closing date
Find your statement closing date (it’s on your statement) and make a payment a few days before it.
3. Make multiple payments each month
Paying twice a month keeps balances lower throughout the cycle.
4. Ask for a credit limit increase
A higher limit with the same balance lowers utilization. Some issuers can increase limits with a soft inquiry; others use a hard inquiry. Only do this if you won’t spend more.
5. Keep old cards open
Closing a card removes its limit from your total, which can raise utilization. If a card has no annual fee, consider keeping it open and using it occasionally for a small purchase you pay off.
6. Spread balances wisely
If you must carry a balance, keeping individual cards from getting close to their limits can help per-card utilization. But don’t open new cards just to spread debt.
7. Consider a balance transfer or consolidation loan
Moving card debt to an installment loan can lower revolving utilization, because installment balances aren’t counted the same way. A balance transfer can lower interest costs, though it may concentrate debt on one card. Compare options with our balance transfer guide and consolidation loan calculator guide.
Utilization myths
“You need to carry a balance to build credit.” False. You don’t need to pay interest. A small balance reported on a statement that you then pay in full by the due date is enough to show activity.
“Utilization stays on your report like late payments.” In most scoring models, utilization is calculated from current reported balances. Lower balances can lift your score quickly. Some newer models consider balance trends over time, but current utilization still matters most.
“Paying in full each month means my utilization is zero.” Not necessarily. It depends on when your issuer reports the balance.
Utilization vs. debt-to-income ratio
| Credit utilization | Debt-to-income ratio | |
|---|---|---|
| Compares | Revolving balances to credit limits | Monthly debt payments to gross income |
| Affects credit score | Yes | No |
| Used by | Credit scoring models | Lenders in underwriting |

If you’re rebuilding credit
High utilization is common after a financial setback. Pair lower utilization with on-time payments and the removal of any inaccurate negative items. Our sister site, Debt Remediation, has a step-by-step guide to rebuilding credit after debt collection.
Frequently asked questions
It’s fine, but some scoring models may give a slightly better score for a small reported balance (1% to 9%) than for zero across all cards.
Often within one or two billing cycles, once issuers report lower balances.
Often yes. The account’s balance and limit may appear on your report and be included in your utilization.
Scoring models handle these differently; some exclude them from utilization calculations.
