Credit Utilization Calculator

Your credit utilization ratio is the percentage of your available credit that you are currently using. It is calculated as total balances divided by total credit limits, multiplied by 100. For example, if your cards have $12,000 in combined limits and $3,400 in combined balances, your overall utilization is 28.3%. Credit scoring models consider this ratio an important factor, and the figures on this page are estimates, not professional financial advice.

Divide the sum of all reported card balances by the sum of all credit limits, then multiply by 100. Each card also gets its own ratio: card balance divided by that card's limit. Both the per-card ratios and the overall ratio are considered by scoring models. This calculator computes both automatically from the limits and balances you enter.

Generally yes. Paying down a balance reduces the numerator of the ratio, so utilization drops. For example, paying $500 on a $1,200 balance against a $5,000 limit moves utilization from 24.0% to 14.0%. Use the what-if box above to model a payment before you make it. Improvements appear once the lower balance is reported, usually at the next statement cycle. This is educational information, not a guarantee of any score change.

As a widely cited rule of thumb, below 30% is considered good and below 10% is considered excellent; these are general guidelines, not guaranteed scoring thresholds, and they do not predict an exact score. Above 50% is generally poor and at or above 75% is generally very poor. Keeping balances low relative to limits is the safest habit, whatever the exact number.

Both. Scoring models look at your overall utilization across all cards and the utilization of each individual card. You can have a healthy overall ratio while one card looks risky: for example, two cards with $10,000 and $2,000 limits carrying $2,500 and $900 balances give an overall utilization of 28.3%, which is fine, but the second card sits at 45.0%, which is in the fair range on its own. Spread or pay down the high-ratio card rather than looking only at the average.

A 0% ratio falls in the excellent band and is generally viewed positively. One nuance: scoring models need reported activity to evaluate you, so some advisors suggest letting a small balance report and then paying in full. Either way, 0% utilization itself is not a penalty. This page treats anything under 10% as excellent.

Utilization has no memory in most scoring models: it is recomputed from your latest reported balances, usually once per statement cycle (roughly monthly). So a lower balance typically shows up in your score within one to two billing cycles. Past high utilization does not haunt you the way a missed payment does.

It can. Closing a card removes its limit from the denominator, which raises your overall ratio even though your balances did not change. Example: $3,400 in balances against $12,000 in limits is 28.3%; close the unused $2,000-limit card and the same $3,400 against $10,000 in limits becomes 34.0%, crossing into the fair band. Consider this math before closing an old card.

Your utilization for that card exceeds 100%, which this calculator flags as over limit and rates very poor. Over-limit balances can also trigger fees or penalty rates from the issuer depending on your card agreement. Bring the balance under the limit as quickly as you can.

Lenders typically report your statement balance — the amount shown when your billing cycle closes — to the credit bureaus, not your real-time balance. That is why timing matters: a card you pay in full each month can still report high utilization if it was heavily used when the statement closed. Enter the balance you expect to be reported for the most realistic estimate.

They can, indirectly. Paying part of the balance before the statement closing date reduces the balance that gets reported, which lowers the utilization ratio the bureaus see. The calculator cannot time your statement dates, but you can enter your expected reported balance to model the effect.

No calculator can honestly answer that. Score changes depend on your full credit profile — payment history, account age, inquiries, and more — and on the exact scoring model version. What this tool can show is the direction: moving from a worse band to a better one is generally viewed positively by scoring models. Treat any site that promises an exact point gain with skepticism; that is not how scoring works.
