About the Credit Utilization Calculator
Credit utilization — how much of your available credit you're using — is one of the biggest factors in your credit score. This calculator shows your overall ratio, your highest single-card ratio, and how much to pay down to get under the widely-suggested 30%.
How it’s calculated
Utilization = total balances ÷ total credit limit × 100. Per-card utilization uses that card's balance and limit. To reach 30%, pay balances down below 30% of the total limit.
Example calculation
With $3,000 in balances against a $12,000 total limit, utilization is 25% — already under the 30% guideline.
Frequently asked questions
What's a good credit utilization?
Under 30% is widely suggested, and under 10% is even better for your score. Both your overall ratio and your highest single-card ratio can matter.
Does paying off a card help my score?
Lowering balances lowers utilization, which can help your score fairly quickly since utilization updates each statement. Keeping cards open preserves your total limit.
