Utilization = balance ÷ credit limit - big FICO lever month to month.
Example: $1,100 balance on $6,000 limit → 18.3% utilization - under the common 30% rule-of-thumb, but per-card and aggregate both matter.

Click a question to expand the answer.
Credit utilization is the percentage of revolving credit you are currently using versus your available limit.
Many credit experts recommend staying below 30%, with under 10% often viewed as stronger.
Yes. Lenders and scoring models can consider both aggregate usage and high utilization on individual cards.
Paying balances down before statement close or requesting higher limits can lower utilization ratio.
No model is identical, but utilization is generally a major factor across most consumer scoring systems.
Utilization = balance ÷ credit limit - big FICO lever month to month.
$1,100 balance on $6,000 limit → 18.3% utilization - under the common 30% rule-of-thumb, but per-card and aggregate both matter.
CLI requests can help if spending is structural, not impulsive. Closed cards lower available credit and can spike utilization overnight. Business cards may not report utilization - don’t assume they help personal score.
