Work-Related Car Expenses

Estimate Eligible Work-Related Car Deductions

If you use your own car for eligible work-related travel, different methods may be available for working out your deduction. This calculator compares the cents per kilometre and the logbook methods, one car at a time.

Your estimate

Enter the work kilometres to compare the two methods.

How this is worked out

Cents per kilometre method: 88c for each work kilometre in 2025-26, up to 5,000 km per car. The rate covers all the car's costs, decline in value included.

Logbook method: the car's expenses for the year, decline in value included, times the share of kilometres driven for work, from a logbook kept for at least 12 continuous weeks.

What this calculator doesn't cover

Working out decline in value: enter the figure from your depreciation schedule
Cars owned or leased by your employer
Travel that isn't for work, such as the trip between home and a regular workplace
