Why Utilization Matters
Credit utilization is your revolving balance divided by your credit limit. In FICO and VantageScore models it is one of the biggest factors after payment history, and lower is better: under 30% is the common advice and people with top scores often stay under 10%. Example: balances of 1,200, 450 and 2,800 on limits of 5,000, 2,000 and 8,000 give 4,450 of 15,000, or 29.7% overall.
Utilization is usually measured from the balance on your statement, not on the due date, so paying before the statement closes lowers it even if you always pay in full. Unlike late payments, high utilization stops affecting most scores once the balance is reported lower. Closing an unused card reduces your total limit and can push the ratio up.
Key Takeaways
- Aim low: Under 30% overall, ideally under 10%.
- Mind the statement date: Pay before it to report a lower balance.
- Spread balances: Avoid maxing out any single card.
