Many credit experts say you should keep your credit utilization ratio — the percentage of your total credit that you use — below 30% to maintain a good or excellent credit score.
Credit utilization is a major factor in your credit scores, so it pays to keep an eye on it. View the 30% rule as a good guideline, but be aware that using even less is better for your score.

How much of my credit card should I use?
Keeping your credit utilization at no more than 30% can help protect your credit. If your credit card has a $1,000 limit, that means you’ll want to have a maximum balance of $300.
Why the 30% rule? It’s likely because the recommendation to keep your credit utilization low invariably prompts the question, “How low?” Having a number gives you an upper limit when thinking about how much to spend on your credit cards.
The 30% answer finds backing from the credit bureau Experian: "The 30% level is not a target, but rather is a maximum limit. Exceeding that level will have significantly negative impact on credit scores," says Rod Griffin, Experian’s senior director of public education and advocacy. "The lower a person’s utilization rate, the better from a scoring standpoint."
Is 0% credit utilization bad?
In general, using as little of your credit card limits as possible is better for your scores. So logic would suggest that paying off your credit cards early so that a zero balance is reported to the credit bureaus would produce the highest scores. But using 1% of your credit limits may help your credit scores even more than 0% usage.
Credit scoring systems are designed to predict how likely you are to repay borrowed money. The two biggest credit factors — accounting for about two-thirds of your scores — are paying on time and the amount you owe.
If you are trying to squeeze every possible point from credit utilization, the trick is to aim low — just above zero. Credit expert John Ulzheimer says that data has shown that 1% credit utilization predicts slightly less risk than 0%, and scoring models reflect that.
Tommy Lee, a senior director at FICO, one of the two dominant credit scores, explains it this way: “Having a low utilization indicates you are using credit in a responsible manner.”
How credit utilization affects your scores
How much you owe on your credit cards relative to your credit limits makes up about 30% of your FICO score and 20% of your VantageScore, a competitor scoring model.
Note that your credit scores are composed of several factors. If your overall credit profile is excellent, it’s unlikely that your credit scores will plunge if your credit utilization ratio rises slightly one month.
And, happily, damage from credit utilization is easily reversed. With the vast majority of scores, as soon as a new, lower balance (or lower credit utilization) is reported to credit bureaus, the harm is undone.

The 30% Utilization Rule. Using no more than 30% of your credit limits is a guideline — and using less is better for your score. Lauren Schwahn is a writer at NerdWallet who covers credit scoring, debt, budgeting and money-saving strategies.
Using more than 30% of your available credit on your cards can hurt your credit score. The lower you can get your balance relative to your limit, the better for your score.
To maintain a healthy credit score, it's important to keep your credit utilization rate (CUR) low. The general rule of thumb has been that you don't want your CUR to exceed 30%, but increasingly financial experts are recommending that you don't want to go above 10% if you really want an excellent credit score.
Your credit utilization rate affects your credit score. Try to keep your overall credit use to about 30% of your overall credit limit, if not lower. Extend your overall credit availability by applying for additional lines of credit, but don't apply for too many at once.

Yes, $30,000 is a high credit card limit. Generally, a high credit card limit is considered to be $5,000 or more, and you will likely need good or excellent credit, along with a solid income, to get a limit of $30,000 or higher.
You should use less than 30% of a $2,500 credit card limit each month in order to avoid damage to your credit score. Having a balance of $750 or less when your monthly statement closes will show that you are responsible about keeping your credit utilization low.
Helps keep Credit UtiliSation Ratio Low: If you have one single card and use 90% of the credit limit, it will naturally bring down the credit utilization score.
Maintaining a 0% utilization rate on all your credit card accounts can help your credit scores, but you can achieve excellent scores without doing so. A low utilization rate, preferably under 10%, is ideal.
"Paid in full will have a positive effect on your credit score, and even more so if all payments were made on time," Castleman said. That's because out of all the factors that are used to calculate your credit score, payment history is the most heavily weighted at 35% of the total score.
Your credit limit is the maximum amount of money a lender permits you to spend on a credit card or line of credit. Going over your credit card limit can result in consequences, including high fees, a drop in your credit score, and even the closure of your account.
Bottom line. If you have a credit card balance, it's typically best to pay it off in full if you can. Carrying a balance can lead to expensive interest charges and growing debt.
