Finance term
Credit Utilization
Also known as: utilization, credit utilization ratio, CUR
Definition
Credit utilization is the percentage of your available credit you're currently using — calculated as total credit card balances divided by total credit limits. Keeping utilization under 30% (ideally under 10%) is the single highest-leverage credit-score factor.
Detailed explanation
Credit utilization is the second-most-weighted FICO score factor (~30% of the score), behind only payment history. It's calculated separately for each card and aggregated across all cards. A single card maxed near its limit can hurt your FICO even if your total utilization across all cards is low.
The reporting cycle matters: utilization is reported on your statement date, not your due date. To improve your utilization-driven FICO, pay your card down BEFORE the statement closes, not just before the due date.
Utilization recovers quickly. A high-utilization month followed by a paid-off statement immediately drops utilization on the next reporting cycle. Unlike payment history (which takes years to recover from a late payment), utilization is a current-snapshot factor.
For borrowers preparing to apply for a major loan (mortgage, auto loan, business loan), the 60-90 day window before application is when paying down credit cards has the most leverage. Sub-10% utilization can produce 20-50 FICO points of improvement in 1-2 statement cycles.
The CFPB's credit report and score guide (https://www.consumerfinance.gov/consumer-tools/credit-reports-and-scores/) explains how credit utilization affects scoring and how to monitor it. The Federal Reserve's Consumer Credit G.19 release (https://www.federalreserve.gov/releases/g19/) tracks aggregate revolving credit data, providing macroeconomic context for credit card utilization trends.
◈ Worked example
- $500 balance on a $10,000 limit = 5% utilization (excellent)
- $2,500 balance on a $10,000 limit = 25% utilization (good)
- $8,000 balance on a $10,000 limit = 80% utilization (significant FICO drag)
Common questions
The most-asked questions about Credit Utilization — answered straightforwardly.
What's a good credit utilization? +
Under 30% on each card and overall is the commonly-cited threshold. Under 10% is excellent. 1-5% reported (not zero — some activity beats no activity) optimizes FICO for borrowers preparing for major credit applications.
Does paying off my card before the due date help? +
Paying off the FULL balance before the STATEMENT date is what reduces reported utilization. The statement date is typically a few weeks before the due date. Pay early — before the statement closes — to optimize utilization-driven FICO.
