What’s considered a good credit utilization ratio?

There’s no single universal number, but keeping utilization low, well below the limit rather than close to it, is generally viewed favorably. Many sources point to roughly 30% and below as a common benchmark, though lower tends to support a stronger score across most systems.

Does paying my balance in full each month affect my utilization ratio?

Yes, generally in a positive way, since a lower reported balance relative to a limit improves the ratio. The balance reported to credit bureaus is sometimes based on a statement balance rather than the balance at the exact moment it’s checked, so timing can matter.

Should I avoid closing a credit card I don’t use anymore?

It’s worth weighing the tradeoff. Closing the account removes its credit limit from total available credit, potentially raising the utilization ratio, while keeping it open, even unused, preserves that available credit. Weighing this against any annual fee, or a reason like reducing identity theft risk on an unmonitored account, helps in deciding what’s right for a given situation.

Does credit utilization work differently for someone with a low starting credit limit?

The mechanics are the same, but the effect is more pronounced. A lower credit limit, common on starter or secured cards, means the same dollar amount of spending represents a larger percentage of what’s available. Someone new to credit isn’t doing anything wrong if their ratio moves more with everyday spending than an established cardholder’s would; it’s a function of the limit, not a sign of financial trouble.

What is credit utilization ratio? How to calculate and improve it

Key takeaways
- Credit utilization ratio compares how much you currently owe to your total available credit.
- It’s calculated both per account and across all your accounts combined.
- Scoring systems generally view being close to a credit limit unfavorably.
- Closing a credit card reduces your total available credit, which can raise your utilization ratio even if your spending hasn’t changed.
- Keeping balances low relative to limits, across all accounts, generally supports a healthier score, and this matters even more for anyone starting out with lower credit limits.

How much of your available credit is currently in use shapes a credit score as much as almost anything else you do with credit. Here’s what the ratio means, and why closing a card you don’t use can work against you.

What is credit utilization ratio?

Credit utilization ratio is the percentage of available credit currently in use, calculated by dividing total balances by total credit limits across accounts. According to the FTC⁠(opens in new window), scoring systems generally look at how close a balance sits to its credit limit, and being maxed out or close to it tends to work against a score.

As a quick example, a $1,000 balance on a card with a $5,000 limit works out to a 20% utilization ratio on that account. With a second card carrying a $500 balance on a $2,000 limit, the overall utilization across both cards would be $1,500 owed against $7,000 available, or about 21%, even though the two cards individually look a little different from each other.

How credit utilization affects your credit score

This ratio is calculated in two ways that both matter for the overall picture:

Per-account utilization. How much is owed on a specific card relative to that card’s own limit.
Overall utilization. How much is owed across all credit accounts relative to combined total available credit.

Both affect a score, but overall utilization often carries more weight. A single maxed-out card can hurt a score even if other accounts have low balances.

Why closing a card can backfire

One of the more counterintuitive consequences of credit utilization involves closing a card that seems harmless to get rid of. Closing an account that’s no longer used removes its credit limit from total available credit. If balances on other accounts stay the same, the overall utilization ratio rises, simply because the total available credit it’s measured against has shrunk. This is why financial guidance often suggests keeping an old, unused account open rather than closing it, specifically to preserve that ratio, a point the CFPB makes directly when debunking common credit score myths⁠(opens in new window). That said, the CFPB also notes real reasons someone might still choose to close a card, including watching for identity theft risk on an account no longer being monitored, or an annual fee that isn’t worth paying for a card sitting unused.

What credit utilization means for newcomers and immigrants

For someone building credit for the first time, understanding utilization early is one of the more effective habits to build, and it matters in a specific way that’s easy to miss. Starter credit products, like a secured credit card⁠(opens in new window), typically come with lower credit limits than an established cardholder would have, sometimes just a few hundred dollars to start. A lower limit means the same, modest spending takes up a larger share of it, so utilization can climb faster than expected even without any change in habits. Being aware of this from the first account, rather than discovering it after a credit score⁠(opens in new window) dips unexpectedly, makes it easier to manage, and it’s a genuinely useful thing to know before the first statement even arrives.

First steps for managing your credit utilization ratio

Keeping balances low relative to each card’s limit, ideally using only a modest share of what’s available, supports a stronger ratio.
Thinking twice before closing an old account is worth it, since doing so reduces total available credit.
Requesting a limit increase on an account used responsibly can improve the ratio without requiring less spending.
For anyone starting with a lower-limit starter card, tracking utilization a little more closely than an established cardholder might need to can help catch a climbing ratio early.

In Summary

Credit utilization ratio is a simple concept with a genuinely counterintuitive consequence: closing a card that isn’t being used can hurt a score by shrinking total available credit, even if spending habits never change. Understanding this, along with how starting limits shape the ratio for anyone newer to credit, helps in making more informed decisions about which accounts to keep open and how to manage balances across all of them. Understand your options before deciding whether to close or keep any credit account.
