About This Calculator
Credit utilization is the percentage of your available revolving credit that you are currently using. Keeping it below 30% (ideally under 10%) is one of the fastest ways to boost your credit score.
Real-world example: $10,000 in total credit limits with a $1,200 balance = 12% utilization. Jump to $6,000 and your score can drop sharply.
