Credit utilization: what it is and how to lower it

The calculation

Utilization is a balance divided by a credit limit, shown as a percentage. Scoring models usually look at two versions:

• Per card: one card's reported balance divided by that card's limit.
• Overall: the total of all reported card balances divided by the total of all card limits.

A card at its limit can weigh on a score even if your overall number is low, so watch both.

Timing: the statement date, not the due date

Many card issuers report your balance to the credit bureaus once a month, usually around the statement closing date. Whatever balance shows on that date is what scoring models see, even if you pay it in full a week later. That is why someone who uses a card heavily and pays in full can still have high reported utilization.

The fix is simple: make a payment a few days before the statement closes. You still pay the remaining statement balance by the due date. Your card's app or statement shows both dates.

Ways to lower utilization

Utilization and carrying a balance

You never need to carry a balance or pay interest to build credit. Paying the statement balance in full each month builds payment history and avoids interest. If you do carry balances, paying them down usually helps both your score and your budget, since card interest rates are high.

When utilization spikes

A large purchase, travel or a move can temporarily push your reported balance up. If you are applying for an apartment, car loan or mortgage soon, pay the card down before the statement date in the month or two before you apply. Otherwise, a single high month is not worth worrying about: once a lower balance is reported, most scoring models reflect it.

Utilization is a ratio, not a verdict

Utilization is one part of a score. On-time payments matter most, and they take time to build. Treat utilization as a lever for the months when your score matters, such as before applying for an apartment or loan, and keep paying every bill on time all year.

Check your numbers each month

Look at each card's statement for the closing date, balance and limit. If a limit changed, recalculate. Issuers sometimes lower limits on cards that are rarely used, which can raise utilization without any new spending, so a small charge every few months on older cards can keep them active.

If you have only one card

With one card, per-card and overall utilization are the same number, so a single large purchase moves it a lot. Paying before the statement date matters even more. As your history grows, a second no-fee card can add available credit, but open it because it fits your budget, not just for the ratio, since each application creates a hard inquiry and new accounts lower your average account age.
