The real cost of owning a car
Your monthly payment is only one part of what a vehicle actually costs.
Separate cash flow from economic cost
Some ownership costs leave your bank account every month, while others are irregular or only become visible when you sell the car. Payments, insurance and fuel are obvious cash-flow items. Tires and repairs arrive occasionally. Depreciation is the loss in resale value over time. A complete comparison should recognize all three types.
Why a lower payment can still mean a higher total cost
A long loan term can reduce the required monthly payment on an expensive vehicle, but the purchase price, interest, insurance and depreciation may still make that vehicle more costly over several years. Payment size tells you about monthly financing pressure; it does not measure the whole ownership experience.
Then consider depreciation separately if you want to compare what different vehicles cost you economically over the same ownership period.
Use ranges for uncertain expenses
Repairs and future resale value are uncertain. Instead of pretending one forecast is exact, run a conservative scenario and an optimistic scenario. If a vehicle only looks affordable when every uncertain number is unusually favourable, that is useful information.
Connect the tools
Start with the payment calculator, add recurring costs in the ownership cost calculator, and use Compare Two Cars when you have two actual vehicles in mind. Using the same assumptions across the tools gives you a more consistent decision.
Your car payment is only the beginning
When people think about the cost of a car, they often focus mainly on the monthly loan or lease payment.
But owning a vehicle usually involves several other expenses that can add up significantly over time.
Insurance
Auto insurance is one of the biggest recurring vehicle expenses for many drivers.
Your cost can vary based on your location, driving history, age, vehicle and coverage.
Fuel
Fuel costs depend on how much you drive, your vehicle's fuel economy and the price of gasoline or diesel.
Even a vehicle that seems inexpensive to buy may become costly if it uses a lot of fuel.
Maintenance
Routine maintenance helps keep a vehicle running properly and can include oil changes, filters, fluids, brakes and inspections.
These costs may not happen every month, but they should still be included in your yearly car budget.
Tires
Tires wear out over time and can be a significant expense, especially if you need separate winter and summer sets.
It can be useful to estimate the yearly cost of tires instead of waiting until they need replacement.
Repairs
Older vehicles may need more frequent repairs, but even newer vehicles can have unexpected problems.
Setting aside some money for repairs can make unexpected costs easier to handle.
Registration and fees
Vehicle registration, licence fees, inspections and other government charges may also need to be included in your ownership budget.
Parking
Depending on where you live or work, parking can become a major monthly expense.
Paid parking at work, school, apartments or downtown areas can change the true cost of owning a vehicle.
Example
Imagine your car payment is $400 per month.
If insurance costs $180, fuel costs $150 and your maintenance, registration, tires and repairs average another $100 per month, your real monthly cost would be closer to $830.
Looking only at the $400 payment would leave out more than half of the actual vehicle expense.
Cost per kilometre
Another useful way to understand vehicle expenses is to calculate your total yearly cost and divide it by the number of kilometres you drive.
This gives you an estimated cost for every kilometre of driving.
What about depreciation?
A vehicle can also lose value over time. This is called depreciation.
Depreciation is different from a direct monthly bill, but it can still be an important part of the long-term cost of owning a vehicle.

Context around the numbers
DriveMath aims to explain why a result matters, not just show a figure. That is why most pages include assumptions, limitations and related next steps.
