Credit Utilization Calculator
How much of your credit you are using, and what to pay down to get under 30% or 10%.
Good to know. Paying a card before the statement date lowers the balance the bureaus see, even if you always pay in full.
Not financial advice. Uses only the numbers and rates you enter — no live data.
How it works
In plain words
Divide the total of your card balances by the total of their limits. To reach a target, the balance must fall to the target share of the limits.
The formula
utilization = balances ÷ limits pay down = balances − target × limits
Worked example
Balances of 2,500 on limits of 10,000 is a utilization of 25%. To get to 10%, pay the balance down to 1,000: 1,500 less.

About the credit utilization calculator
Credit utilization is how much of your available credit card limit you are using. It is one of the biggest factors in common credit scores, after paying on time: lower utilization signals that you are not stretched.
Under 30% is the usual rule of thumb, and people with the highest scores tend to use under 10%. Both the overall figure and each card’s own ratio can count, so one maxed-out card can hurt even when the total is low.
Utilization is measured from the balances your card issuers report, usually the statement balance. Paying part of a balance before the statement closes lowers what is reported, even if you pay the rest in full afterwards and never pay interest.
Unlike late payments, utilization has no memory in most scoring models: bring it down and your score can recover within a month or two. Closing an old card lowers your total limit and so raises utilization; asking for a higher limit lowers it, as long as spending stays the same. To clear the balances themselves, see the credit card payoff calculator.
Questions people ask
What is a good credit utilization ratio?
Under 30% is generally fine; under 10% is typical of excellent scores. 0% can be slightly worse than a small balance in some models.
Is utilization per card or overall?
Both can matter. Keep each card, as well as the total, under your target.
How fast does lowering utilization help my score?
Usually as soon as the lower balances are reported, often within one or two billing cycles.
