The 10:30% refers to the class used for the Capital Cost Allowance (CCA). This figure is correct as it is not affected by the percentage of personal use. The class/percentage are determined by the vehicle itself, not the business/personal ratio.

The expense calculation for business versus personal use is determined by the total number of km used for business versus the total km driven in the year. As long as you've entered these amounts accurately, the correct percentage will be applied to all of your vehicle expenses.
