Credit Utilization: Per-Card vs Overall

The short answer: Both matter. Scoring models look at your overall (aggregate) utilization across all cards and the utilization on each individual card, and a single maxed-out card can hurt even if your overall ratio is low. Keep both well under 30 percent, ideally under 10, by paying down or spreading balances.

Two numbers, both counted

Credit scoring weighs utilization two ways: your overall ratio (total balances divided by total limits across all cards) and your per-card ratio on each account. Aggregate utilization carries the most weight, but a single card near its limit can still ding your score even when your overall number looks fine.

Why a maxed card hurts

If one card is at 90 percent of its limit while others sit empty, models can flag that individual card as a risk signal regardless of the low aggregate. So spreading a balance across cards, or paying down the most-utilized card first, can help your score even if your total owed does not change.

How to manage both

Keep every card and your total under 30 percent, ideally under 10. Levers: pay down before the statement closes so a lower number reports, request a credit limit increase to lower the ratio, and avoid concentrating spending on one card near its limit. See how to improve your score.

Frequently asked questions

Does per-card or overall utilization matter more?
Overall (aggregate) utilization carries the most weight, but per-card utilization also counts, so a single maxed-out card can hurt your score even if your overall ratio is low.
Should I spread my balance across cards to lower utilization?
It can help, because a single card near its limit can hurt even at low overall utilization. But paying balances down is better than just moving them around.
