Estimated business-use percentage
0%
Enter your kilometres above.
Your business-use percentage is calculated using:
Business kilometres ÷ Total kilometres × 100
For example, if you travelled 6,250 kilometres during your logbook period and 4,125 kilometres were for business:
4,125 ÷ 6,250 × 100 = 66% business use
Your business-use percentage can be used as part of the ATO logbook method to calculate eligible car expense deductions.

Travel Logs can automatically record your trips and separate business and personal travel, making it easier to keep track of your vehicle use throughout the year.
Instead of manually adding up your kilometres, you can review your recorded trips and business-use information directly in Travel Logs.
This calculator provides an estimate only and does not constitute tax or financial advice. Eligibility for deductions depends on your individual circumstances and current ATO requirements.
