Use this credit utilization calculator to estimate how much of your available revolving credit is being used. It is useful for monitoring credit card balances and understanding one factor that may affect credit scores.
Formula
Credit utilization = total card balances / total credit limits x 100
- Total card balances are the amounts currently owed.
- Total credit limits are the combined limits on revolving credit accounts.
- The result is shown as a percentage of available credit being used.
Worked example

- Opening new credit only to lower utilization without considering other effects.
