Credit Utilization Ratio: What It Is and How It Affects Your Credit Score
Learn what the credit utilization ratio is, how to calculate it, what percentage is considered good, how it affects your credit score, and practical ways to lower your utilization and manage your credit more effectively.
What Is Credit Utilization?
Credit utilization is the amount of revolving credit you are using compared with the total amount of credit available to you. It is commonly expressed as a percentage and is one of the important factors considered in many credit scoring models.
For example, if your credit cards have a combined credit limit of $10,000 and your current balances total $2,000, your overall credit utilization ratio is 20%.
Your credit score can affect many parts of your financial life. It may influence the interest rates you receive when borrowing money, the credit products available to you, and how lenders evaluate your applications. That makes understanding the factors behind your credit score important.
One of the most commonly discussed factors is your credit utilization ratio. If you use credit cards, understanding credit utilization can help you make better decisions about balances, payments and available credit.
The good news is that credit utilization is relatively simple to understand. Once you know how the calculation works, you can see how changes to your balances or credit limits may affect your utilization.
What Is Credit Utilization?
Credit utilization ratio measures how much of your available revolving credit you are currently using.
Revolving credit generally includes credit cards and other accounts where you have a credit limit and can repeatedly borrow, repay and borrow again.
Your utilization ratio compares your credit card balances with your available credit limits. The lower the percentage, the less of your available revolving credit you are using.
Credit utilization can be considered at both the individual account level and across all of your revolving credit accounts.
How to Calculate Your Credit Utilization Ratio
Calculating credit utilization is straightforward. Divide your outstanding credit card balance by your total available credit limit, then multiply the result by 100.
Suppose your credit card has a $10,000 credit limit and your balance is $2,000.
$2,000 ÷ $10,000 = 0.20
0.20 × 100 = 20%
Your credit utilization ratio would therefore be 20%.
Example With Multiple Credit Cards
Your overall utilization can be calculated using the combined balances and combined credit limits of your revolving accounts.
| Credit Card | Balance | Credit Limit |
|---|---|---|
| Card A | $1,000 | $5,000 |
| Card B | $500 | $5,000 |
| Card C | $1,500 | $10,000 |
| Total | $3,000 | $20,000 |
In this example, total utilization is $3,000 divided by $20,000, resulting in an overall credit utilization ratio of 15%.
What Is a Good Credit Utilization Ratio?
You will often hear that keeping credit utilization below 30% is a good target. This is a useful general guideline, but it should not be treated as a universal cutoff.
In general, lower utilization is viewed more favorably by many credit scoring models than high utilization. However, having a utilization ratio above 30% does not automatically mean that your credit score will be poor.
| Utilization | General Interpretation |
|---|---|
| 0% | No reported revolving balance |
| 1%–9% | Very low utilization |
| 10%–29% | Generally considered low utilization |
| 30%–49% | Moderate utilization |
| 50%–74% | High utilization |
| 75%–99% | Very high utilization |
| 100%+ | Credit limit reached or exceeded |
These ranges are useful for understanding the concept, but credit scoring is more complicated than one utilization percentage. Different scoring models can weigh information differently.
You should therefore avoid thinking of 30% as a magic line where your credit score suddenly changes. Instead, think of it as a practical guideline: keeping revolving balances relatively low compared with your available limits can generally be beneficial.
Why Does Credit Utilization Matter?
Credit utilization matters because it can provide information about how heavily you are relying on revolving credit.
A person who consistently uses a large portion of their available credit may appear to have less financial flexibility than someone who uses a relatively small portion of their available credit.
Credit scoring models can consider this information when calculating credit scores.
High Utilization Can Hurt Your Credit Score
High credit utilization may negatively affect your credit score, particularly when a large balance is reported relative to your credit limits.
For example, using $9,000 of a $10,000 credit limit means you are using 90% of your available credit. That is substantially different from using $1,000 of the same $10,000 limit.
Utilization Can Change Quickly
One important feature of credit utilization is that it can change relatively quickly.
If your balance falls while your credit limits remain unchanged, your utilization can fall as well. Likewise, a large purchase can cause utilization to rise.
This means utilization is different from some other credit factors that may depend on a longer history.
Individual Credit Utilization vs. Overall Utilization
It is important to understand that credit utilization can be viewed in more than one way.
Overall Credit Utilization
Overall utilization looks at your combined revolving balances compared with your combined credit limits.
For example, if you have $5,000 in total balances and $25,000 in total credit limits, your overall utilization is 20%.
Individual Credit Card Utilization
Each credit card can also have its own utilization ratio.
Suppose you have two credit cards:
- Card A: $900 balance on a $10,000 limit
- Card B: $900 balance on a $1,000 limit
Your overall utilization would be relatively low, but Card B would have a very high individual utilization ratio.
This is one reason why it can be useful to monitor both your total utilization and the utilization of individual credit cards.
Why Your Statement Balance Can Matter
Many people assume that paying their credit card bill by the due date is the only thing that matters. Paying on time is extremely important, but the balance reported to the credit bureaus can also affect the utilization that appears on your credit reports.
Credit card issuers commonly report account information to credit reporting agencies. The timing and reporting practices can vary by issuer.
As a result, you could pay your balance in full every month and still have a utilization percentage reported if a balance is reported before your payment reduces it.
If utilization is important to you, understanding your card issuer's statement and reporting cycle can help you better understand what may appear on your credit reports.
How to Lower Your Credit Utilization
If your credit utilization is high, there are several practical ways you may be able to reduce it.
Pay Down Credit Card Balances
Reducing your revolving balances is one of the most direct ways to lower your utilization ratio.
Make More Than One Payment
Instead of waiting until the end of the billing cycle, some people make multiple payments during the month to keep balances lower.
Avoid Unnecessary Large Balances
Planning major purchases and paying balances down promptly can help prevent your utilization from becoming unnecessarily high.
Consider a Credit Limit Increase
If an issuer increases your credit limit and your balances remain the same, your utilization percentage can decrease.
Spread Balances Carefully
If you have multiple cards, monitoring individual card balances can help you understand how much of each account's available credit you are using.
Can a Credit Limit Increase Help Your Credit Utilization?
A credit limit increase can lower your utilization ratio if your balances do not increase along with the new limit.
Balance: $3,000
Credit limit: $5,000
Utilization: 60%
Balance: $3,000
New credit limit: $10,000
Utilization: 30%
However, requesting a higher credit limit can have different effects depending on the issuer and the circumstances. Some issuers may perform a hard credit inquiry when evaluating a request, while others may not.
Before requesting an increase, check the issuer's terms and understand whether the request could involve a credit inquiry.
Does Closing a Credit Card Affect Credit Utilization?
Closing a credit card can affect your overall available revolving credit.
For example, suppose you have two cards with a combined credit limit of $20,000 and balances of $2,000. Your overall utilization is 10%.
If you close a card with a $10,000 limit while the $2,000 balance remains on the other card, your available credit could fall to $10,000. Your utilization would then become 20%.
This is why closing a credit card solely because you no longer use it may not always be the best decision from a credit-utilization perspective.
However, there are other factors to consider when deciding whether to keep or close a credit card, including annual fees, account benefits, spending habits and the issuer's terms.
Common Credit Utilization Mistakes to Avoid
1. Treating 30% as a Magic Number
The commonly cited 30% guideline is useful, but it is not a universal rule that guarantees a particular credit score.
2. Carrying a Balance Just to Build Credit
You generally do not need to carry credit card debt from month to month simply to build credit. Carrying a balance can result in interest charges depending on your card terms.
3. Ignoring Individual Card Utilization
Looking only at your overall utilization can cause you to miss the fact that one card is carrying a disproportionately high balance.
4. Maxing Out a Card
Using nearly all of a credit card's available limit can produce a very high utilization ratio and may negatively affect your credit score.
5. Closing Cards Without Considering Available Credit
Closing an account can reduce your total available credit, potentially increasing your overall utilization if you have balances on other cards.
6. Forgetting About Credit Limits
Credit utilization depends on both your balance and your available credit. Monitoring your limits can therefore be just as important as monitoring your balances.
Credit Utilization and the Bigger Credit Picture
Credit utilization is important, but it is only one part of your overall credit profile. If you want to improve your credit, it is useful to understand the other major factors that can influence credit scoring.
- Payment history: Paying bills on time is an important part of responsible credit management.
- Credit utilization: The amount of revolving credit you use compared with your available limits can affect credit scores.
- Length of credit history: The age and history of your accounts can be relevant to some credit scoring models.
- New credit: Opening multiple new accounts or applying for credit frequently can affect your credit profile.
- Credit mix: Different types of credit accounts may be considered by some scoring models.

Credit Utilization FAQs
What is a good credit utilization ratio?
Lower utilization is generally viewed more favorably than high utilization. A commonly cited guideline is to keep utilization below 30%, although there is no universal percentage that guarantees a particular credit score.
Is 30% credit utilization too high?
Thirty percent is often used as a general guideline, not a hard cutoff. Credit scoring models consider multiple factors, and your score does not automatically become bad when utilization exceeds 30%.
Is 0% credit utilization good?
A 0% reported utilization means no revolving balance was reported at that time. However, you do not generally need to avoid using credit cards simply to maintain a 0% utilization ratio. Responsible use and on-time payments are important.
Does paying off a credit card improve utilization?
Paying down a credit card balance reduces the amount of revolving credit you are using. Once the lower balance is reported, your utilization ratio can decrease.
Can high credit utilization lower my credit score?
Yes. High revolving credit utilization can negatively affect credit scores because utilization is considered by many credit scoring models.
Does credit utilization apply to debit cards?
No. Debit cards generally do not have revolving credit limits. Credit utilization primarily concerns revolving credit accounts, such as credit cards.
Does credit utilization reset every month?
Utilization can change as balances and credit limits change. Credit card issuers may report account information at different times, so the utilization appearing on your credit report can vary.

Generally, carrying a balance and paying interest is not necessary simply to build credit. You can use a credit card responsibly and pay your balance according to your card terms without intentionally carrying debt for credit-building purposes.

It can. If your credit limit increases while your balance stays the same, the percentage of available credit you are using decreases. However, check whether the issuer may perform a credit inquiry when requesting an increase.
Does closing a credit card increase utilization?
It can increase your overall utilization if closing the account reduces your total available credit while balances remain on other accounts.
