About the Credit Utilization Calculator
Credit utilization is the share of your available revolving credit that you are using. It is one of the biggest factors in credit scores. Lenders and scoring models look at both your overall ratio and the ratio on each card. This calculator shows both and tells you how much to pay down to reach common targets.
How to use it
- Enter the balance and credit limit of each credit card. Leave unused rows empty.
- Press Calculate utilization.
- Review your overall ratio, each card's ratio and the pay-down amounts for 30%, 10% and 1%.
Utilization formula
Utilization = total balances ÷ total credit limits × 100. $2,500 of balances on $10,000 of limits is 25%.
Ways to lower utilization
- Pay balances down before the statement closing date, not just the due date.
- Ask for a credit limit increase without a hard inquiry when possible.
- Spread balances across cards instead of maxing one.
- Avoid closing old cards, which lowers your total available credit.
Frequently asked questions
What is a good credit utilization ratio?
Below 30% is a common guideline and below 10% is often associated with the best scores.
Does utilization affect my credit score?
Yes. It is part of the amounts-owed category, one of the most influential parts of many scoring models.
Does paying in full each month mean 0% utilization?
Not necessarily. Issuers usually report the statement balance, so a card used heavily before the statement date can show high utilization even if you pay in full.
Is per-card utilization important?
Yes. A single maxed-out card can lower your score even if overall utilization is moderate.
How fast does utilization change my score?
It updates as soon as your issuers report new balances, often within one billing cycle.
