Credit utilization means how much of your credit limits you're using. It's also called "balance to limit."
Credit utilization only applies to credit cards and personal lines of credit.
You can improve credit utilization by paying down credit card balances or increasing your available credit.
Just imagine—you find your dream home and qualify for the mortgage on your first try. Or you visit a car dealership and snag the amazing offer you saw in a social media ad. Or you decide to consolidate your high-interest credit card debt with a loan that charges a fraction of the interest and get approved within minutes of applying.
What these scenarios have in common is healthy credit. And if your credit standing isn’t as excellent as you want it to be, there’s a good chance that utilization is holding you back.
You can be the master of your credit score. Once you understand what factors affect it and how to control those factors, you can do what you need to do to make your credit standing the best it can be.
Let’s find out what credit utilization is all about.
What is credit utilization?
Here's a simple credit utilization definition: It's how much of your available revolving credit you're using. (Revolving credit means credit cards and personal lines of credit).
Credit utilization is also called “credit usage” or “balance to limit.” That last one refers to how you calculate credit utilization—by dividing your account balance by your credit limit.
Here’s how it works.
If you have a $700 balance on a credit card that has a $1,000 credit limit, your utilization is 70%. Credit utilization describes how much you owe on your credit cards versus how much spending power you have.
There are two ways that credit scores look at utilization:
By individual card
For all your credit cards combined
Why does credit utilization matter?
Credit utilization matters for one reason: it's a big part of your credit score calculations. In fact, credit utilization makes up 30% of your FICO score.
A lower credit utilization is a good thing where your credit scores are concerned.
Using up more of your available credit could work against you.
For example, if you've got five credit cards and you're maxed out on all five, lenders might raise an eyebrow. It could look like you're desperate for money or careless with spending, which could get you denied new credit cards or loans.
Higher credit utilization doesn't automatically mean you're bad with money, though.
Suppose that you charge all your monthly bills to one credit card, then pay it off at the end of each month. Until your credit card issuer reports your payment, your utilization appears very high. But the fact that you're paying in full (and hopefully, on time) means that you know how to manage your debt responsibly.
How to calculate your credit utilization
Wondering what your credit utilization ratio looks like? It’s not hard to do the math. Here's the formula:
Credit card balance / Credit card limit x 100 = Credit utilization ratio (stated as a %)
Let's look at some examples.
Say that you have four credit cards:
Card A has a $2,500 balance and a $5,000 limit
Card B has a $1,000 and $3,000 limit
Card C has a $10,000 balance and a $12,000 limit
Card D has a $500 balance and a $4,000 limit
You can use the formula above to work out your credit utilization for each card separately, then for all your cards together.
Your utilization calculations for each card look like this:
Card A: $2,500 / $5,000 x 100 = 50%
Card B: $1,000 / $3,000 x 100 = 33%
Card C: $10,000 / $12,000 x 100 = 83%
Card D: $500 / $4,000 x 100 = 12.5%
To calculate the overall credit utilization for all your cards together:
Add all the card balances together: $2,500 + $1,000 + $10,000 + $500 = $14,000
Next, add up all the credit limits: $5,000 + $3,000 + $12,000 + $4,000 = $24,000.
Overall credit utilization ratio = $14,000/$24,000 = 58%
Nothing too tricky about any of the math required. And calculating your credit utilization can give you an idea of whether the way you use credit might be hurting or helping your scores.
Tips to manage your credit utilization
If you're working on improving your credit scores, then lowering your credit usage is one way to do it.
There are some different ways of managing credit utilization to help your credit scores:
Raise your limits. One of the quickest ways to improve your credit usage is to increase your credit limits. Ask each of your credit card issuers for a credit limit increase. Note that if the creditor does a hard credit check, that can have a temporary negative impact on your score.
Pay down balances. Paying down existing balances helps your utilization and your wallet. Consider tackling your debt with the avalanche or snowball method.
Transfer balances. Opening a balance transfer credit card increases your available credit. When you open a new card, your overall utilization ratio goes down as long as there isn’t a balance on that new card. A balance transfer could help you make more progress against your debt if you can get low or no interest for a period of time.
Consolidate debts. Debt consolidation involves taking out a new loan to pay off credit card balances. Paying off your revolving credit with a personal loan or a home equity loan could drop your utilization to zero.
Balance your spending. Even if your credit utilization overall is low, putting too much on any one card can hurt your FICO score or impact your chances with lenders. Try to spread your spending more evenly across your cards.
Pay your credit card balances more than once a month if you tend to charge a lot. This keeps utilization consistently lower.
Create automatic small charges—for instance, a regular bill like Netflix—and then set up an electronic monthly payment to cover it. This is helpful if you don’t use credit very much.
Debt consolidation loans and balance transfers don’t make debt go away. They just change the type of debt you owe. If you transfer your balances and then run up the accounts you just paid off, your financial situation could get a lot worse. The same goes if you increase your credit limits and use the extra credit to charge more purchases.
If you get a balance transfer, pay attention to when the introductory interest rate ends. If you don’t pay off the transferred balance by then, it’ll be subject to the credit card’s regular interest rate. Balance transfers sometimes lead to a pattern of moving balances back and forth, which can lead to bigger financial problems.
The myth of the 30% rule
What's a good credit utilization ratio? If you ask some financial experts, they might point you to the 30% rule.
This "rule" says that an ideal credit utilization ratio is 30% or less. So, if your credit card limits total $10,000, you shouldn't use more than $3,000 of that at any given time.
But that's just an arbitrary guideline, and it’s not guaranteed to help your score. In fact, FICO suggests shooting for 10% instead and paying bills on time to grow a healthy credit score.
You might be tempted to go lower than that and reduce your credit usage to 0%. Sounds good, but there's a hitch. If you're not using your credit cards, then there's no activity to report to the credit bureaus. And there might not be any payment history either. Over time, the lack of activity could keep you from earning the highest score possible. Use the automatic bill pay trick mentioned above to use credit, keep utilization low, and build a positive payment history.
How credit utilization affects your financial health
Credit utilization directly affects your credit scores, but there's more to it than that. Maintaining a good utilization ratio is good for your overall financial health.
Here are a few reasons why:
Lower credit utilization makes it easier to get approved for new loans or lines of credit.
Keeping your balances low means you’ll have emergency credit when you need it.
Using less credit means less debt to repay.
Aiming for a low credit utilization ratio is a good habit that can keep you from overspending and blowing your monthly budget.
It may be easier to keep up with debt payments (and avoid late payments) if you're not relying heavily on credit cards.
Now, can high credit utilization hurt? Yes. Increasing balances means you’re spending more than you make. That can’t go on forever because eventually, you’ll run out of credit. In that case, you might have to look into solutions like debt management or debt resolution to lighten the load financially.
Credit utilization is just one factor that affects your credit
Credit utilization is important, but another factor is even more critical for good credit. That’s your payment history. Other categories like the average age of your accounts and how much new credit you’re applying for also affect your credit score and how lenders view your financial profile.
Knowing how credit utilization works is just one part of the plan to improve your credit standing. And in the long run, picking up that kind of knowledge can pay off when it's time to borrow.

Frequently asked questions
What happens if my credit utilization ratio is too high?
A too-high credit utilization ratio could hurt your credit scores. It’s the second-most influential factor affecting your credit standing, behind payment history. High utilization can make you ineligible for the lowest interest rates or make it harder to get more credit when you need it.
Can paying off my balances in full every month improve my credit utilization ratio?
Paying off balances in full could improve your credit utilization ratio if you're doing so consistently and paying your bills on time. Credit scoring models tend to work best when you're actively feeding in new information, including paying off balances.
Does credit utilization impact all types of credit?
The credit utilization ratio only includes revolving credit lines, like credit cards or personal lines of credit. With these types of credit, your balance can go up or down over time as you make purchases and pay them off. Installment loans, on the other hand, only go down over time as you make monthly payments, so they are not included in credit utilization calculations. Utilization is not calculated on personal loans, home equity loans, or HELOCs.
