Credit utilization is the share of your available revolving credit that you are using: total card balances divided by total credit limits, times 100. Owing $2,500 against $10,000 of limits gives 25%. To bring that down to 10%, the combined balance would need to drop to $1,000, a reduction of $1,500.
Lenders and scoring models look at how much of your revolving credit is in use, both per card and across all cards. This calculator takes your combined balances and combined limits, returns the utilization ratio, places it in a band from very low to very high, and shows the unused credit left. A target slider tells you the largest balance that keeps you at or under a chosen level and how much you would have to pay down to get there. It works with the figures you type in; it cannot see what each issuer reports to the credit bureaus, which is usually the statement balance on the closing date, so a card paid in full after the statement can still report a balance.
Add the current or statement balances of all revolving accounts and type the total.
Type the combined credit limits of those same accounts.
Move the slider to the utilization level you want to reach, such as 30% or 10%.

Result Credit utilization: 30%
Utilization band: 30–49% – moderate
Unused credit: $700.00
Highest balance at your target: $300.00
Pay down to reach target: $0.00
One card carrying 30% of its limit sits right at the line many lenders watch.
Result Credit utilization: 25%
Utilization band: 10–29% – low
Unused credit: $7,500.00
Highest balance at your target: $1,000.00
Pay down to reach target: $1,500.00
Combined utilization is 25%; reaching 10% means the total balance has to fall to $1,000.
U = B ÷ L × 100; allowed balance = L × T ÷ 100; pay down = max(0, B − allowed balance)
UBLTThe ratio is the definition used by the Consumer Financial Protection Bureau: what you owe on revolving accounts divided by what you could borrow on them. The bands are a reading aid; scoring models do not publish exact cut-offs, though lower is generally treated as better and 30% is a widely quoted ceiling. Installment debts such as car finance are not part of this ratio.
Many lenders and credit educators treat staying under 30% as a reasonable ceiling, and people with the highest scores often show single-digit utilization. There is no official cut-off published by the scoring companies, so read the bands here as a guide rather than a rule.
Zero utilization across every card is not harmful in itself, but some scoring models treat a small reported balance slightly more favourably than none at all, since it shows active use. The difference is minor compared with the gap between low and high utilization.
Both. Scoring models look at the combined ratio and at individual accounts. This calculator works on totals; to check a single card, enter only that card's balance and limit.
Issuers usually report the statement balance on the closing date. If you pay after the statement is cut, the reported figure still reflects the spending for that cycle. Paying part of the balance before the closing date lowers what gets reported.
Yes, arithmetically. Raising combined limits from $10,000 to $12,500 with a $2,500 balance takes utilization from 25% to 20%. The request may trigger a hard inquiry with some issuers, so check how they handle it first.
Utilization has no long memory in most scoring models: once the lower balance is reported, usually within one statement cycle, the ratio used in the score reflects it. Late payments and other history items, by contrast, stay on the report for years.
