Credit Utilization

What is Credit Utilization?

Credit utilization refers to the ratio of your current credit card balances
compared to your total available credit limits. It is typically expressed as a
percentage. For example, if you have a total credit limit of $10,000 across all
your credit cards and carry a combined balance of $3,000, your credit
utilization rate is 30 percent.

Why It Matters for Your Credit

Credit utilization is generally considered one of the most influential factors
in determining your credit score. Under widely used scoring models, it
typically accounts for approximately 30 percent of your overall score. Lenders
may view a high utilization rate as a signal that you are overly reliant on
borrowed funds, which could suggest higher financial risk. Keeping your
utilization rate low, generally below 30 percent, may help support a healthier
credit profile over time.

It is worth noting that utilization is typically calculated both overall and
per individual card. Even if your total utilization is low, a single card
carrying a high balance relative to its limit may still affect your score.

A Practical Example

Suppose you have two credit cards. Card A has a $5,000 limit with a $4,500
balance. Card B has a $5,000 limit with a $500 balance. Your overall
utilization is 50 percent, which may negatively impact your score. However,
Card A alone carries a 90 percent utilization rate, which could create an
additional drag on your credit profile. Paying down the balance on Card A, even
partially, may provide a meaningful improvement.

The good news is that credit utilization is one of the more responsive factors
in credit scoring. As balances decrease, your utilization rate generally
improves, and your score may reflect that change relatively quickly.
