Excludes parking, tolls and financing interest — add them to the fixed costs if relevant.
Car Cost per Km Calculator
Calculate your real cost per kilometer: fuel, insurance, maintenance and depreciation — with monthly and annual totals.
What does a kilometer of driving really cost?
Most drivers only think about fuel, but fuel is usually less than half the true cost. The calculator combines two cost types:
Variable costs (per km)
Fuel: price per liter × consumption per 100 km ÷ 100.
Fixed costs (annual)
Insurance, maintenance (service, tires, repairs) and depreciation — the largest and most overlooked cost: the difference between your car's value today and a year from now. Fixed costs are divided by your annual mileage.
Use the result to compare against public transport, mileage reimbursement, or a second-car decision.
💡 Useful Tips
Typical depreciation: 10%–15% of the car’s value per year (higher for new cars).
The more you drive, the lower the per-km cost — fixed costs spread over more kilometers.
Add annual parking and tolls to fixed costs if relevant.
Frequently Asked Questions
Why does depreciation count as a cost?
Because it is real money lost: the gap between purchase and resale price, spread over the years of ownership. It is usually a car’s single largest cost.
Does this work for EVs?
Yes — replace fuel price with electricity cost using the consumption field (e.g. 15 kWh/100 km × price per kWh).
What is a typical cost per km?
For a typical family car: roughly $0.30–$0.60 per km all-in, depending on mileage and car value.
