See the full cost of owning a car over several years, not just the price on the sticker.
Enter your ownership assumptions
Covers purchase price, running cost, maintenance, insurance and resale together.
Why total cost of ownership tells a fuller story than sticker price
Two cars with similar purchase prices can end up costing very differently once you account for fuel or electricity, maintenance, insurance, and how much value the car retains at resale. This calculator combines all four into a single ownership-period figure so you can compare cars on a more even footing than sticker price alone.
Where the running cost per km figure comes from
Use the Fuel Cost Calculator or EV Running Cost Calculator first to work out your cost per km, then bring that figure into this tool alongside your maintenance and insurance estimates.
Frequently asked questions
How do I estimate resale value percentage?+
Resale value depends heavily on brand, model, condition and market demand at the time of sale. Check current listings for similar-age, similar-mileage cars as a starting benchmark, and adjust the percentage accordingly.
Should I include loan interest in this calculator?+
This tool focuses on ownership and running costs rather than financing costs. If you're financing the purchase, use the Car Loan Calculator alongside this tool to see your full financial picture.
