Your credit utilization - which is the amount of your credit card balance compared to the credit limit - plays a major role in your credit score. Making up 30% of your credit score, credit utilization the second biggest factor that influences your credit score, next to payment history.

Having a good credit utilization is important if you want to build and maintain a good credit score. As your credit utilization increases, your credit score can go down.

A high credit utilization indicates that you're likely spending a lot of your monthly income on debt payments which puts you at a higher risk of defaulting on your payments.

A high credit utilization could lead to your credit card and loan applications being denied. If you are approved, you may have to pay higher interest rates or make a larger down payment than if you had a good credit utilization.

What is a Good Credit Utilization?

The best credit utilization is 0% - that means you're not using any of your available credit. However, if you use your credit cards at all, chances are, your credit report won't reflect a zero balance. That's ok.

Generally, a good credit utilization ratio less than 30%. That means you're using less than 30% of the total credit available to you. To achieve 30% credit utilization, you should keep your balances below 30% of the credit limit. Anything above 30% can cause your credit score to drop.

On a credit card with a $1,000 limit, that means keeping your balance below $300.

Calculating Credit Utilization

Since your credit utilization is a simple ratio, you can easily estimate your own credit utilization. You only need know your credit limits and credit card balances. You can get this information by checking your most recent credit card statement or by logging into your online account.

Credit utilization is calculated by dividing a credit card's balance by the credit limit. The result will be a decimal, like 0.5678, for example. Multiply that number by 100 (or simply move the decimal two places to the right) to get a percentage. The result is your credit utilization expressed as a percentage - - 56.78% in our example.

When your credit score is calculated, it uses the credit card information available on your credit report which may differ from your online account balance. This happens when you've paid or used your credit card since the last time your account information was updated on your credit report.

How to Lower Your Utilization

Credit utilization is a fluid number. It changes as your credit card balance and credit limits change. You have the ability to lower a high credit utilization and it will reflect on your credit report and in your credit score the next time your credit card issuer reports your balance information. There are generally two ways you can improve your credit utilization.

First, you can reduce your credit card balances. Pay as much as you can toward your credit card to reduce your credit utilization quickly. Keep in mind that your credit card issuer may not report your balance until the end of your billing cycle, so leave your balance low until then to ensure is shows up on your credit report.

If you can't afford to pay down your balance right away, refrain from new credit card purchases and reduce your balance as much as you can.

Another way to lower your credit utilization is to have your credit card issuer increase your credit limit, which may not be easy, depending on your income, credit history, and time since your last credit limit increase.
