1. What is Credit Utilization Ratio?

The Credit Utilization Ratio (CUR) is a key factor in credit scoring models that measures the amount of credit you're using compared to your total available credit. It's expressed as a percentage and is calculated by dividing your current credit card balance by your credit limit.

2. How Does the Calculator Work?

The calculator uses the Credit Utilization Ratio formula:

Where:

• \( B \) — Current credit card balance (currency unit)
• \( CL \) — Credit limit (currency unit)
• \( CUR \) — Credit utilization ratio (%)

Explanation: The formula shows what percentage of your available credit you're currently using. Lower percentages are better for your credit score.

3. Importance of Credit Utilization

Details: Credit utilization makes up about 30% of your FICO credit score. Keeping your utilization below 30% is generally recommended, and below 10% is ideal for optimal credit scores.

4. Using the Calculator

Tips: Enter your current credit card balance and total credit limit in dollars. Both values must be positive numbers, with credit limit greater than zero.
