Vehicle Expense Calculator for Business

Vehicle expense calculator

Enter your total annual vehicle costs and your business kilometres. The calculator works out your business-use percentage, the deductible share of your costs, and the estimated tax saving. Keep a separate calculation for each vehicle you use.

How this is estimated: the calculator multiplies your total vehicle costs by the business-use share (business kilometres ÷ total kilometres) and then by your marginal tax rate. It does not apply CCA limits, lease caps or input tax credit rules — confirm on canada.ca.
