Credit Utilization Calculator
Calculate your credit utilization ratio across one or more cards and how much to pay down to hit a target.
About this calculator
Credit utilization, the share of your total available credit you're currently carrying as balance, is one of the most heavily weighted factors in most credit scoring models, second only to payment history, yet most people only see it as a vague percentage buried in a credit report rather than something they can actively target. This calculator takes your total balance across cards and your total credit limit, computes Utilization = Total balance ÷ Total credit limit × 100, and compares it against a target utilization percentage you set, reporting exactly how much you'd need to pay down (or how much room you have) to reach that target. Because utilization is measured both per-card and in aggregate by scoring models, a single maxed-out card can drag down your score even if your overall ratio looks fine, so use this alongside checking individual card balances rather than only the combined total. Keeping utilization low, ideally under 30% and ideally under 10% for the best scoring impact, is one of the fastest levers you can pull to improve a credit score, since it reflects current behavior rather than years of history.
Worked example
$2,000 balance on a $10,000 total limit
Result: 20% utilization, already under the 30% target
