How It Works

The formula is: Credit Utilization = (Total Balances ÷ Total Credit Limits) × 100, expressed as a percentage. As a worked example: if you have three cards with balances of $500, $800, and $200 (total $1,500) and credit limits of $4,000, $3,000, and $3,000 (total $10,000), your utilization is ($1,500 ÷ $10,000) × 100 = 15%. Available credit is simply Total Credit Limits minus Total Balances: $10,000 − $1,500 = $8,500. To calculate how much you need to pay down to reach a target utilization, rearrange the formula: Target Balance = Target Utilization % × Total Limit ÷ 100. To reach 10% utilization with a $10,000 total limit, your combined balance must be $10,000 × 0.10 = $1,000 or less, meaning you'd need to pay down an additional $500.

Examples

Excellent Utilization
A cardholder has $500 in statement balances across all cards with a total limit of $10,000.
Result: Shows a utilization ratio of 5%, which is excellent for maximizing a credit score.
Borderline Utilization
Carrying a balance of $3,500 on cards with a $10,000 combined limit.
Result: Shows a utilization ratio of 35%, slightly above the recommended 30% threshold.
Maxed Out Cards
Balances total $4,800 against a $5,000 combined credit limit.
Result: Calculates a 96% utilization ratio, which will severely damage a credit score.

Frequently Asked Questions

What is a good credit utilization ratio?
Financial experts recommend keeping utilization below 30% to avoid negative scoring impacts. For the best possible scores, aim for under 10%. The difference between 1% and 9% utilization is negligible, but the difference between 9% and 30% — and especially between 30% and above — has a meaningful effect on FICO and VantageScore models. Having some utilization (rather than 0%) may be very slightly better than zero, as it shows active revolving account use.
How much does utilization impact my credit score?
In standard FICO scoring models, 'amounts owed' — which is heavily weighted toward credit utilization — accounts for approximately 30% of your total score. This makes it the second most influential factor after payment history (35%). Because utilization is recalculated every time a creditor reports to the bureaus (typically monthly), it is one of the fastest factors to change, for better or worse.
Does utilization apply per card or as a total?
Both matter. Credit bureaus evaluate your aggregate utilization across all revolving accounts and your per-card utilization on each individual account. A card at 90% utilization can still hurt your score even if your overall utilization is low. If you have multiple cards, spreading balances to keep each individual card's utilization low — rather than concentrating debt on one card — typically produces better results for your score.
