What is a good credit utilization ratio?

A commonly cited educational guideline is to keep overall utilization at or below 30%, and at or below 10% may be even better. These are reference points, not official scoring tiers. The exact impact on your credit score depends on the scoring model and your overall credit profile.

Does overall utilization or per-card utilization matter more?

Both can matter. Most scoring models consider both your overall utilization across all cards and the utilization on individual cards. This calculator focuses on overall utilization.

Reference Points

The 10% and 30% thresholds are commonly discussed educational reference points, not official universal scoring tiers or guaranteed score outcomes. The amounts below show what balance would produce utilization at or below each reference point for your credit limit.

30%At or below 30%

$1,500 balance

Your current balance of $1,500 is already at or below the 30% reference point of $1,500.

10%At or below 10%

$500 balance

To reach 10% utilization or lower, reduce your balance by $1,000 — from $1,500 to $500, which corresponds to exactly 10%.

How This Calculator Works

Calculation: Credit utilization is the ratio of your total credit card balances to your total credit limits, expressed as a percentage. For example, if you carry $1,500 in balances across cards with a combined $5,000 in limits, your utilization is 30%.

Reference points: The 10% and 30% thresholds are commonly discussed educational reference points, not official universal scoring tiers. Lower utilization may help your credit scores, but effects vary by scoring model and your overall credit profile. No specific utilization percentage guarantees a particular score outcome.

Per-card vs. overall: This calculator measures overall utilization. Most credit scoring models also consider the utilization ratio on each individual card. Keeping balances low on every card — not just in aggregate — is generally beneficial.
