What Is Credit Utilization and Why Does It Matter?
Credit utilization is the percentage of your available revolving credit that you are currently using. If you have a credit card with a $10,000 limit and a $3,000 balance, your utilization on that card is 30%. Your overall utilization is calculated across all your revolving accounts combined.
Utilization is the second most important factor in your FICO score, accounting for roughly 30% of the total. Payment history is first at 35%, but utilization is the factor most people can change quickly — sometimes within a single billing cycle — without needing new accounts or years of history.
Scoring models reward low utilization because it signals that you are not over-extended. Lenders view borrowers with low utilization as lower risk. Conversely, high utilization — even if you pay your balance in full every month — can suppress your score because the balance is captured at statement close, before your payment posts.
The 30% threshold is the most commonly cited target, and crossing below it typically adds 20–50 points. But the biggest rewards come below 10%: people with scores above 800 typically carry utilization under 7%. If you are preparing for a major credit application — a mortgage, car loan, or business line of credit — reducing utilization to under 10% in the months prior can meaningfully improve the rate you are offered.
Frequently Asked Questions
- Does closing a credit card hurt utilization?
- Yes. Closing a card reduces your total available credit, which raises your utilization ratio automatically. If you must close a card, pay down other balances first to offset the impact.
- Does getting a credit limit increase help?
- Immediately, yes — a higher limit with the same balance means lower utilization. Card issuers sometimes increase limits automatically; you can also request one, which may involve a soft or hard inquiry depending on the issuer.
- Is per-card or overall utilization more important?
- Both matter. Overall utilization is the primary driver, but FICO also evaluates utilization on individual accounts. A single maxed-out card can drag your score even if your overall ratio is low.
