How much does it cost to own a car per year?
The price on the window is only the start. Most people underestimate what a car costs because the expenses arrive in small pieces across the year. Adding them up once gives you a number you can plan around.

The costs to count
Split what you spend into two groups. Fixed costs are paid whether or not you drive. Running costs grow with every kilometre.
- Fixed: insurance, annual road tax or registration, inspection fees, parking or garage rent, and loan payments.
- Running: fuel or charging, oil and tires, repairs, servicing, tolls, and car washes.
- Depreciation: the value your car loses each year. It is not a bill you pay, but it is often the single biggest cost of a newer car.
A simple yearly formula
Yearly cost = fixed costs + running costs + depreciation
Cost per km = yearly cost ÷ kilometres driven in the year
For example, if you spend $5,000 in a year and drive 12,000 km, your car costs about $0.42 per km. That is roughly $0.67 per mile.
Why the monthly view misleads
Some bills only come once or twice a year: insurance renewal, tax, inspections, new tires. If you only look at fuel and the monthly payment, the car seems cheap until a large bill arrives. Spread each yearly cost across 12 months and set that amount aside, and surprises mostly disappear.
Ways to bring the number down
- Compare insurance quotes at each renewal.
- Keep tires inflated and follow the service schedule to protect fuel economy and avoid larger repairs.
- Combine short trips and drive smoothly.
- Before buying, compare the running costs of the models you are considering, not just their prices.
