Credit utilization, explained simply

5 min read·Education only·Reviewed by James Cox

The short version

Credit utilization is how much of your available credit you are using. It is the second-biggest factor in a credit score.

It is also the one people can often change fastest, which makes it worth understanding well before you apply.

01

What it means

If you have a card with a limit and you owe a balance on it, the proportion you are using is your utilization on that card. Add up all your revolving balances and all your limits, and you get the overall figure.

Lenders read high utilization as a sign that money is tight, even when it is not. A balance carried for convenience looks the same on a report as a balance carried out of necessity.

02

Why it moves a score so quickly

Utilization is calculated from your current balances, which means it updates every month. That cuts both ways: it can drag a score down faster than almost anything else, and it can lift one just as fast.

This is why paying down a card is sometimes worth more than waiting for a better rate. Your monthly obligations are weighed against your income, so reducing a balance can change what is possible for you even before your score moves at all.

03

The timing detail people miss

Card issuers generally report your balance on a statement date, not the day you pay. So a card you pay in full every month can still report a balance if you use it heavily between statements.

That is not a problem you need to solve forever. It is just worth knowing before you apply, so you are not surprised by what a lender sees.

04

What to do about it

The straightforward move is to bring balances down and keep them there in the months before you apply. If you have cards you never use, keeping them open generally helps more than closing them, because the available limit still counts.

How much this matters depends on your whole file. For someone with strong credit and a small balance, it matters little. For someone carrying a lot across several cards, it can be the difference between one set of options and another.

Asked most often

Questions that come up every time.

Should I close a card I do not use?

Usually not. Closing a card removes its available limit from the calculation, which can push your utilization up. Keeping it open with a zero balance generally helps more than closing it, though there are situations where closing makes sense.

Do I need to carry a balance to build credit?

No. Carrying a balance costs you interest and pushes your utilization up. Using a card and paying it off is what builds a payment history; the balance itself does nothing for you.

Does utilization matter if my score is already good?

It matters less, but it is still part of the picture. How much it moves the needle depends on everything else in your file, which is why it is worth looking at together rather than in isolation.
