Credit Utilisation Calculator

Divide what you have used by the limit. 2,400,000 against a 6,000,000 limit is 40%. Set the target at 30% and the balance has to be 1,800,000, so 600,000 comes off; leave the balance alone and it would take a limit of 8,000,000 instead. That is the character of this ratio: raising the limit lowers it without a unit of debt being repaid.

What it means

Utilisation is 40%, over the 30% target. Getting the balance to 1800000 means paying down 600000, or holding a limit of 8000000.

Formula

Utilisation = Balance used ÷ Credit limit × 100, Balance at that target = Credit limit × Target utilisation ÷ 100

Per-card and overall utilisation are usually read together — pile everything on one card and the overall figure stays low while that card reads high. Timing is the bigger trap: utilisation is often captured from the statement-date balance rather than the due date, so paying after the statement cuts leaves a high number on this month's record. How scoring models use the ratio, and where any threshold sits, differs by country and bureau. What this page gives you is the ratio.

Step by step

FormulaUtilisation = Balance used ÷ Credit limit × 100, Balance at that target = Credit limit × Target utilisation ÷ 100
With the default numbersUtilisation = 2,400,000 ÷ 6,000,000 × 100, Balance at that target = 6,000,000 × 30 ÷ 100
AnswerUtilisation = 40 %

Frequently asked questions

Q. How is Credit Utilisation Calculator calculated?

Utilisation = Balance used ÷ Credit limit × 100, Balance at that target = Credit limit × Target utilisation ÷ 100 — Divide what you have used by the limit. 2,400,000 against a 6,000,000 limit is 40%. Set the target at 30% and the balance has to be 1,800,000, so 600,000 comes off; leave the balance alone and it would take a limit of 8,000,000 instead. That is the character of this ratio: raising the limit lowers it without a unit of debt being repaid.

Q. Can you walk through an example?

With Balance used 2,400,000, Credit limit 6,000,000, Target utilisation 30%, the answer is Utilisation 40%.

Q. What do I need to enter?

Enter Balance used, Credit limit, Target utilisation. The result recalculates as you type, and an empty box counts as zero.

Q. How much does the answer move if I change a number?

Changing only Balance used moves the answer to Balance used 1,200,000 → Utilisation (%) 20 and Balance used 4,800,000 → Utilisation (%) 80. The table below lays out five steps.

Q. How are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

Q. Anything to watch out for?

Per-card and overall utilisation are usually read together — pile everything on one card and the overall figure stays low while that card reads high. Timing is the bigger trap: utilisation is often captured from the statement-date balance rather than the due date, so paying after the statement cuts leaves a high number on this month's record.
