Credit utilization, explained

Utilization is the share of your revolving credit limits you're using. If you have $2,000 in card balances and $5,000 in total limits, your overall utilization is 40%. Scoring models look at overall utilization and at each card.

There's no magic number, but lower is generally better. Many people aim to stay under 30%, and the strongest scores often show single-digit utilization. The difference between a small reported balance and zero is minor compared with avoiding high utilization.

To find what to pay: multiply the limit by your target percentage, then subtract that from the balance. On a $3,000 limit, getting under 30% means a balance below $900; under 9% means below $270.

Our free credit utilization calculator does this for up to six cards and shows both overall and per-card numbers.

Card issuers usually report the balance on your statement date, not your due date. Paying down before the statement closes can lower the reported balance. Utilization has no long memory in most models, so improvements can show up quickly once reported. That makes it a useful lever before a mortgage or car loan application.

Every card has two important dates each month. The statement closing date ends the billing cycle; the balance on that date becomes your statement balance and is usually what the issuer reports to the bureaus. The due date is when payment is due to avoid a late fee and, if you pay in full, interest. Card issuers must deliver statements at least 21 days before the payment due date (15 U.S.C. § 1666b), so the two dates are always weeks apart.

1. 1Find your closing date on your statement or in your card's app.
2. 2A few days before it, pay the balance down to your target. On a $2,000 limit, a 10% target means a balance under $200.
3. 3Let the statement close with the lower balance. That's the number that gets reported.
4. 4Pay whatever remains by the due date so you never pay interest or a late fee.

Some people make two payments a month, one before the closing date and one by the due date. It costs nothing extra and keeps reported balances low without changing how much you spend.

• Closing a card removes its limit and can raise overall utilization.
• A creditor lowering your limit has the same effect.
• A card reporting no limit (or a wrong one) can make utilization look worse; if it's wrong, dispute it.
• Requesting a higher limit may help, but it can involve a hard inquiry; ask first.

Scoring models look at both your total utilization and how each card is doing. A single card near its limit can weigh on your score even if your overall ratio looks fine. Example: $900 on a $1,000 card plus $0 on a $9,000 card is 9% overall, but one card is at 90%.

If you're carrying balances, spreading them so no single card is near its limit can help, but paying balances down is what helps most. The calculator shows both views at once.

A higher limit lowers utilization on the same balance, so it can help if you don't increase spending. Before you ask, find out whether the issuer will do a hard inquiry; policies vary. A limit increase is only useful if you treat it as breathing room rather than extra spending money.

Going over your limit is less of a trap than it used to be: card issuers generally can't charge an over-the-limit fee unless you've opted in to allow over-limit transactions (15 U.S.C. § 1637(k)). Even so, a balance over the limit reports as more than 100% utilization on that card.

• Today: run your numbers in the calculator, and pull your reports to confirm every card shows the right limit.
• Before each statement date: pay balances down to your target, starting with any card above 50%.
• If a limit is missing or wrong: dispute it. A missing limit can make a card look maxed out.
• Throughout: avoid new card applications and keep every account current.
• Two cycles later: check that the lower balances have been reported before you apply.

Scoring models differ on this. Some treat having no revolving balance reported at all slightly differently from having a small one, but the difference is minor compared with the effect of high utilization. What matters most is not carrying high balances relative to your limits.

You never need to carry debt or pay interest to score well. If you want something to report, let one small recurring charge post to a card, let the statement close, and pay it in full by the due date. That also keeps the card active; some issuers close cards that go unused for a long time, which would remove that card's limit from your utilization math.
