The price on the windshield is only the start. Over several years, what you spend to buy, insure, fuel, maintain and eventually sell a car can add up to far more than the original price. Knowing the full picture helps you choose a vehicle you can actually afford.
This is general information, not financial advice. Costs change over time and differ by province, vehicle and driver, so use real quotes.
The main cost categories
| Category | Type | What drives it |
|---|---|---|
| Depreciation | Hidden, spread over years | Age, model, kilometres, condition, market demand |
| Financing interest | Fixed by contract | Loan amount, rate, term, credit |
| Insurance | Recurring | Province, driving record, vehicle, use |
| Fuel or electricity | Variable | Distance driven, fuel economy, energy prices |
| Maintenance and repairs | Variable | Age, reliability, driving conditions |
| Tires | Periodic | Size, type, climate, driving style |
| Registration and fees | Recurring | Province, vehicle type |
| Parking and tolls | Variable | City, work, lifestyle |
| Taxes | One-time at purchase | Province and price |
Depreciation: the quiet cost
Depreciation is the drop in a vehicle’s value over time. It does not appear on a bill, but it is often the largest cost of ownership. New cars usually lose a larger share of value early on, while older cars lose less per year but need more repairs.
You cannot predict the exact loss, but you can compare models by looking at what similar used vehicles sell for compared with their new price. Read car depreciation in Canada for the patterns and how to think about them.
Financing costs
If you borrow, interest adds to the total cost. A longer term lowers monthly payments but often increases the total paid and keeps you owing more than the car is worth for longer. Learn how interest rates work and compare terms in car loan length. A larger down payment reduces the amount you finance; see how much down payment to make.
Rates change often, so always get current quotes from lenders and review the FCAC’s consumer information on borrowing.
Insurance
Insurance is mandatory and can be one of the largest recurring costs, particularly in some cities or for drivers with limited history. Premiums depend on your province, driving record, vehicle, use and coverage. Always get a quote for the exact car before you buy it. The car insurance guide explains how coverage and pricing work.
Fuel and energy
Fuel cost depends on how far you drive, how efficient the vehicle is and local prices. In Canada, fuel economy is measured in litres per 100 kilometres (L/100 km), where a lower number means less fuel used. To compare vehicles, multiply your yearly distance by the L/100 km figure, divide by 100, then multiply by the local price per litre.
Example with made-up numbers: 15,000 km a year at 8.0 L/100 km uses 1,200 litres. At a price of $1.60 a litre, that is $1,920 a year. Replace the price with what you actually pay.
See fuel economy in L/100 km for how to compare fairly, using official ratings from Natural Resources Canada. For electric vehicles, the cost of electricity and charging setup matter instead.
Maintenance and repairs
Maintenance includes oil changes, filters, brakes, fluids, batteries and scheduled services. Repairs are unplanned. New cars have warranties that cover many repairs for a time, while older vehicles generally cost more to keep running. Follow your manufacturer’s schedule; the basic car maintenance schedule is a good starting point.
A set aside amount each month, even when nothing is wrong, avoids shocks. For vehicles outside warranty, consider whether an extended warranty is worth its price, or whether self-funding repairs makes more sense.
Tires and seasonal costs
Canadian driving often calls for winter tires, which are a significant periodic expense, and in Quebec and on some BC highways they are legally required in winter. You may also pay for seasonal swaps, wheel storage and balancing. See winter tires for the details, and add tire replacement to your yearly budget based on how long sets typically last for your driving.
Registration, fees and taxes
- Registration and plate fees vary by province and vehicle.
- Sales tax at purchase depends on the province: GST of 5% applies nationally, HST is 13% in Ontario and 15% in Atlantic provinces, QST is 9.975% in Quebec, and PST rates apply in BC (7%), Saskatchewan (6%) and Manitoba (7%). Alberta has no PST. For details and exceptions see sales tax on cars.
- Dealer fees such as administration or freight can add to cost; read dealership fees.
- Some jurisdictions have extra fees for certain vehicles, so check locally.
Parking, tolls and other costs
If you live or work in a city, parking can be a monthly expense. Tolls, car washes, accessories and cleaning add up. Include them if they are regular.
A simple way to build your budget
- Pick the vehicle you are considering, and note the price and likely resale value in a few years.
- Get a real insurance quote for that vehicle.
- Estimate fuel using your yearly distance, the vehicle’s L/100 km and local fuel prices.
- Add maintenance and tires based on age and schedule.
- Add financing interest if you borrow, using a lender’s quote.
- Add registration and parking.
- Subtract expected resale value from the purchase price to find depreciation.
- Total it per year and per month, and compare with your income.
Comparing two vehicles this way often shows that the cheaper car to buy is not always the cheaper one to own.
Ways to lower the cost
- Choose a reliable, fuel-efficient model with strong resale value.
- Keep the car longer, since depreciation per year slows as it ages.
- Shop insurance every renewal.
- Maintain the car on schedule to avoid bigger repairs.
- Avoid long loan terms that keep you in negative equity.
- Consider whether you need a bigger vehicle or AWD for everyday use.
Key takeaways
- Count the full cost: depreciation, financing, insurance, fuel, maintenance, tires, fees and taxes.
- Depreciation is often the largest cost but rarely appears on a bill.
- Use real quotes for insurance, loans and local fuel prices, not averages.
- Compare vehicles by yearly and monthly total cost, not only purchase price.
- Budget for winter tires and maintenance, and keep a reserve for repairs.
Frequently asked questions
What is the biggest cost of owning a car?
For many vehicles, depreciation is the largest cost, followed by financing interest, insurance and fuel. The mix varies by vehicle and how long you keep it. New cars tend to lose more value early, while older cars shift cost toward maintenance and repairs.
How do I estimate my annual car costs?
List fixed costs such as insurance, registration and loan payments, then variable costs such as fuel, maintenance, tires and parking. Estimate depreciation from typical resale values for your model. Use real quotes for your address and driving, not national averages.
Is it cheaper to buy used than new?
Often the purchase price and early depreciation are lower with a used car, but repair risk and a shorter warranty may offset some savings. The right answer depends on the specific vehicle, its history and your budget. Compare total costs over the years you plan to keep it.
Do electric vehicles cost less to own?
They can, because electricity and maintenance may cost less than gasoline and servicing, but purchase price, charging access, insurance, incentives and depreciation vary. Incentive programs change, so confirm current availability with official sources and compare the full costs.
