Plain-English explanation
Utilization is calculated per card and across all cards. Lower utilization — especially under 30%, and ideally under 10% — supports higher credit scores.
Why it matters
Paying down cards before a mortgage application can boost your score enough to improve your rate tier.
Where you may see it
- Credit report
- Credit card statements
A real-world example
You have $10,000 in available credit and $4,000 in balances — a 40% utilization. Paying it down to $800 (8%) can lift your score.
Educational and illustrative only
A common misunderstanding
Utilization is not the same as carrying a balance and paying interest — it's calculated from your reported balance regardless of whether you pay it in full.
