Buying or using a car seems simple when the focus is only on the price or the installment. The problem shows up later, when the monthly expense starts to slip out of control.
For those just starting out, the total cost of owning a car (TCO) can be understood with a straightforward checklist. Three fronts concentrate most of the impact on your wallet and already give a good sense of the real bill.
1) Fuel: the expense that never fails
Fuel is predictable, but it’s rarely calculated calmly. Small differences in consumption turn into a hole by the end of the year.
Before deciding, it’s worth putting on paper:
- How many kilometers you drive per month, not per idealized week - The model’s real average consumption (not just the catalog number) - Fuel price in your region, not the lowest one you saw once
A simple example: driving 1,000 km per month with a car that does 10 km/l costs much more than with another that does 14 km/l. The monthly difference seems small, but over 12 months it pays for a full service.
2) Maintenance: the cost that appears little by little
Maintenance isn’t only when something breaks. The biggest weight is in the sum of services, replacements, and small repairs over time.
For beginners, the basic checklist includes:
- Average price of periodic services - Cost of wear items (tires, brake pads, battery) - Frequency of these replacements in your typical use
Popular models tend to have cheaper parts and well-known labor. Less common cars, on the other hand, may seem like a good deal to buy, but charge the difference at the shop.
Preventive costs less than surprises
Ignoring preventive maintenance almost always costs more. Changing oil, filters, and belts on schedule helps avoid large and unpredictable expenses that disrupt any budget.
3) Insurance and depreciation: protection and loss of value
Here are two costs that many beginners underestimate, but that weigh on TCO.
With insurance, pay attention to:
- Annual value, not just the monthly installment - Driver profile and region of use - Deductible and coverages that actually make sense
Depreciation is the money the car loses over time, even sitting in the garage. Some points help anticipate this:
- Models that are very expensive to maintain tend to depreciate faster - Frequent changes in version or styling affect resale price - Above-average mileage accelerates loss of value
How to use the checklist without complicating things
You don’t need a sophisticated spreadsheet. An honest estimate already works better than ignoring the costs.
- Add monthly fuel + average monthly maintenance - Add annual insurance divided by 12 - Consider how much less the car may be worth after a few years
This final number isn’t meant to scare you, but to compare options. Often, the difference between two similar cars shows up exactly in these invisible items.
The most common mistake for beginners
Focusing only on the installment or the purchase price. The car fits in the financing, but not in the day-to-day budget.
The TCO checklist helps flip the logic: first understand the real monthly cost, then decide whether it makes sense to move forward. For your wallet, this order usually ends up much cheaper.
