The proportion of your limit you use

Credit utilisation usually describes your credit card balance as a percentage of your credit limit. For several cards, overall utilisation uses the combined balances divided by the combined limits.

This calculator uses the figures you enter. A report may show a different balance because lenders report on their own schedules.

One factor, not the whole story

Using a large share of available credit can be considered in credit scoring and lending assessments. Lower utilisation is not a promise of a better score or an accepted application.

Payment history, recent applications and other information matter too. There is no universal percentage that guarantees a lender decision.

Consider affordability first

  • Stay within your limit and meet payments on time.
  • Do not raise a limit or open another account just to change a percentage.
  • Where affordable, paying down balances reduces the debt you owe.
  • If repayments are becoming difficult, seek free debt advice rather than focusing on a score.

Utilisation is one factor among many. It does not determine your score or a lender’s decision.
