Credit Utilization Calculator
Credit utilization is how much of your available credit you are using — your reported balance divided by your credit limit, shown as a percentage. It is an important part of the amounts-owed category, which makes up about 30% of FICO Scores in FICO's published weights, second only to payment history. This calculator is free, needs no login, and runs entirely in your browser.
Enter each card's balance and credit limit, and you will instantly see your per-card utilization for each card plus your overall utilization across all of them — all calculated in your browser.
Your cards
Enter at least one card's balance and credit limit to see your utilization.

How credit utilization works
What utilization is
Utilization is your reported balance divided by your credit limit, shown as a percentage. It is an important part of the amounts-owed category — about 30% of FICO Scores in FICO's published weights — so after paying on time it is the lever you control most directly.
Per-card vs overall
Utilization is scored two ways that both matter: per-card (each individual card) and overall (all balances divided by all limits). Maxing out one card can hurt you even when your total across every card still looks low.
Timing: the statement closing date
Issuers usually report your balance on the statement closing date, not on the due date about three weeks later. Pay down to a small amount a few days before the statement closes so a tiny balance is usually what reports, then pay the rest by the due date to avoid interest.
On target — Under 10% overall. The target we teach: under 10% on each card and overall — not 30%.
Above the target — Above the 10% target. Pay this down toward under 10% before the statement closing date.
High — Between 30% and 50% is working against you. Pay this down toward under 10% to put utilization back in your favor.
Critical — Over 50% is a significant drag on your score. Prioritize paying this down, starting with your most-maxed card first.
How to lower it
- Pay down a few days before your statement closing date. Issuers usually report the balance that shows when the statement closes — not your due-date balance about three weeks later — so a small balance at close is usually what reports.
- Keep no-annual-fee cards open. Closing a card removes its limit from your total, which can raise your overall utilization even if you owe the same amount.
- Ask for a credit-limit increase. A higher limit lowers your utilization even when your spending does not change — and ask whether your issuer can do it without a hard inquiry, since that varies by issuer.
- Pay your most-maxed card first. Per-card utilization matters, so taking one maxed card down helps more than spreading the same payment thin across several already-low cards.

How this tool works
Utilization is your reported balance divided by your credit limit, calculated per card and overall. It is an important part of the "amounts owed" category, which is about 30% of a FICO score in FICO's published weights (source: myFICO). The calculator runs entirely in your browser — nothing you enter is stored or sent anywhere.
Frequently asked questions
What is a good utilization ratio?
The target we teach is under 10% on each card and overall — not 30%.
Is utilization measured per card or overall?
Both. Your score looks at each card on its own (per-card) and at all your balances divided by all your limits (overall), so maxing out a single card can hurt you even if your total looks low.
Does this calculator affect my credit or store my data?
No. It is educational and runs entirely in your browser — no login, nothing is sent anywhere, and it is not a credit pull. It does nothing to your credit and saves none of your numbers.
How do I lower my utilization quickly?
Pay your balance down before your statement closing date, since that is usually the balance that reports. Focus on your most-maxed card first, and ask your issuer for a credit-limit increase (ideally without a hard inquiry).
Is 0% utilization best?
Zero isn’t a goal in itself. Experian says 0% gives no extra benefit, and myFICO says that in some cases a low ratio helps more than not using any of your available credit at all; neither names a dollar amount to leave on a card. Use your cards, pay in full, and never carry a balance to help your score. The target we teach: under 10% on each card and overall.
