Credit Utilization: How Much of Your Limit to Use, Per Card and Overall

Credit utilization is the share of your available credit card limits that you’re using, shown as a percentage. If your cards have $5,000 in total limits and your balances add up to $1,000, your utilization is 20 percent, and that number feeds the “amounts owed” part of your credit score [1][2].

Utilization matters because amounts owed is the second-biggest category in a FICO Score, after payment history [2]. The good news: unlike a late payment, it reflects your balances right now, so it can change from one month to the next [1].

How the ratio is figured

Scoring models look at utilization two ways [1]:

• Per card. Each card’s balance divided by that card’s limit.
• Overall. All your card balances added together, divided by all your card limits added together.

Here’s an example with three cards. The overall figure isn’t the average of the three percentages. It’s the totals divided [1].

In that example, the overall number looks low, but Card B is more than half used. Because scores look at each card as well as the total, one card near its limit can still count against you [1].

Your statement date is the date that counts

Most people assume their card company reports whatever they owe on the due date. Usually it doesn’t. Card issuers typically report your balance to the credit bureaus as of the day your statement closes each month [1]. That’s often a few weeks before the payment is due.

So if you charge $1,800 on a $2,000 card and pay it all off by the due date, the bureaus may still see a 90 percent balance for that month. You paid no interest, but your reported utilization was high. The CFPB points out the same timing issue: scores are calculated on different dates, and a high balance on the day a score is figured can lower it even if you pay it off soon after [4].

Why it moves quickly

Most of what’s in your credit report sticks around. A late payment can be reported for years. Utilization is different. FICO says that as soon as you lower your ratio, your FICO Scores respond [1]. Pay a balance down, wait for the next report, and the new, lower number is what scores see.

That also means a single high month isn’t permanent. If a big expense pushed a card near its limit, paying it down brings the ratio back once the lower balance is reported [1].

Myths worth dropping

“You have to carry a balance to build credit.” You don’t. The CFPB says paying your cards in full every month is the best way to improve a credit score, and carrying a balance just means paying interest [5].

“Zero percent is perfect.” Not quite. FICO says a 0 percent ratio gives its scores less information and can keep you from earning the most points for amounts owed [1]. Using a card for a small purchase and paying the full statement balance gives the scores something to work with, without costing you interest.

“Your score drops the moment you cross 30 percent.” Thirty percent is a common rule of thumb. The CFPB describes it as what experts advise [3]. FICO says the data doesn’t support the idea of a sudden drop at that line [1]. Think of it as “lower is generally better,” not a cliff.

“Closing an old card I don’t use will help.” It can do the opposite. Closing a card removes its limit from your total. If your balances stay the same, your overall utilization goes up [1][5].

“Checking my own credit will hurt it.” It won’t. Pulling your own credit report doesn’t affect your scores [5].

Ways to keep utilization low

• Pay before the statement closes, as described above, if you use your cards heavily during the month.
• Pay more than once a month. Smaller, more frequent payments keep the running balance down.
• Spread spending across cards so no single card sits near its limit, since each card is scored on its own as well as in the total [1].
• Keep unused cards open if they don’t charge an annual fee, so their limits stay in your total [1]. Check them now and then for fraud.
• Watch for a lowered limit. If an issuer cuts your limit, the same balance becomes a bigger percentage.

What utilization can’t do

Utilization is one part of your score. Payment history is the biggest single part of a FICO Score, at 35 percent [2]. A low ratio won’t cancel out missed payments, and a high one won’t erase a long record of paying on time. Accurate negative items, such as a late payment, stay on your report for the period the law allows. Nobody can remove accurate, current information early, including companies that charge for credit help [6].

If a balance or limit on your report is simply wrong, that’s different. You can dispute errors with the credit bureau and with the card company for free [6]. Start by pulling your reports, as explained in Free Credit Reports: Weekly From All Three Bureaus, and the Only Official Site.
