How to Calculate Your Credit Card Utilization Rate

Credit card utilization is one of the most critical factors in determining your credit score. It represents the percentage of your available credit that you are currently using. Credit scoring models, like FICO and VantageScore, use this ratio to assess how responsibly you manage revolving credit.

The Credit Utilization Formula

Calculating your utilization rate is a straightforward mathematical process. The formula is:

Utilization Rate = (Total Credit Card Balances / Total Credit Limits) x 100

Practical Example

Suppose you have one credit card with a $1,000 credit limit. If your current statement shows a balance of $300, your calculation would look like this:

• $300 (Balance) ÷ $1,000 (Limit) = 0.30
• 0.30 x 100 = 30% Utilization

Total vs. Individual Card Utilization

Lenders and credit bureaus look at two types of utilization:

1. Per-Card Utilization: The ratio on each specific credit card you own.
2. Aggregate Utilization: The total balance across all your cards divided by the total of all your credit limits combined.

To maintain a healthy credit score, it is recommended to keep both your individual and aggregate utilization rates below 30%, though staying under 10% is considered optimal for the highest credit scores.

How Utilization Impacts Your Credit Score

In the FICO scoring model, "Amounts Owed" accounts for 30% of your total score. Since credit utilization is the primary component of this category, a high utilization rate can lead to a significant drop in your credit score, even if you make all your payments on time. Conversely, paying down your balances to lower your utilization is one of the fastest ways to see an improvement in your credit health.

Tips to Improve Your Utilization Rate

• Pay balances early: Pay your bill before the statement closing date so a lower balance is reported to the bureaus.
• Request a limit increase: Increasing your credit limit (without increasing your spending) automatically lowers your utilization ratio.
• Keep accounts open: Closing an old credit card reduces your total available credit, which can spike your aggregate utilization.
• Spread out spending: If one card is nearly maxed out, it may hurt your score even if your total utilization is low.
