Car ownership costs are not just fuel. Learn how to calculate servicing, insurance, tires, depreciation, and EV charging, and how to avoid common mistakes.
Car ownership costs, basics, examples, and the most common mistakes
If you’re wondering how much a car really costs, the purchase price is only the beginning. Car ownership costs include fuel or energy, insurance, servicing, tires, inspections, repairs, car washes, parking, and often also depreciation. In practice, it’s these ongoing expenses that determine whether a given model is financially comfortable for you, or starts straining your budget sooner than you expected.
In this article, we go through the basics, show examples, and discuss the most common budgeting mistakes. If you’re interested in the broader context of this department, also check out motoryzacja and our guides on the blog.
What makes up car ownership costs
The simplest way to divide expenses is into three groups. First, fixed costs, meaning those that appear regardless of how much you drive. Second, variable costs, which rise with mileage. Third, one-time or occasional costs, which drivers often fail to include, yet they can seriously disrupt a household budget.
- Fixed costs, third-party liability insurance, sometimes comprehensive insurance, parking fees, subscriptions, garage.
- Variable costs, fuel, electric car charging, windshield washer fluid, brake and tire wear, oil service.
- Periodic costs, technical inspection, timing belt replacement, brake pads, discs, 12 V battery, seasonal tire change.
- Less obvious costs, car wash, minor repairs, road charges, fines are not counted as a planned cost, but financial risk is worth keeping in mind.
According to the total cost of ownership approach used, among others, by industry organizations and manufacturers, looking only at the purchase price usually leads to an overly optimistic assessment. This is especially important when you compare a new car, Used car purchase, or a car with financing.
An example of a simple monthly budget
Let’s assume you drive a gasoline car 15,000 km a year. If the car averages 6.5 l per 100 km, then at a fuel price of PLN 6.50 per liter, the annual fuel cost will be about PLN 6,337. That works out to a little over PLN 528 per month. On top of that comes insurance, for example PLN 1,500 per year, or PLN 125 per month, and servicing set aside, for example PLN 2,400 per year, or PLN 200 per month. At this point you’re already at about PLN 853 per month, before adding tires, parking, repairs, and depreciation.
If you want to calculate wisely, don’t just ask how much fuel the car uses. Also ask how much servicing costs, what the wear items cost, and how often repairs typical for that model occur. This is especially important when deciding on a Used car purchase, where the service history and technical condition can significantly change the real cost of ownership.
Electric car charging, how much does it really cost
With an electric car, running costs depend on the charging method. You calculate differently when charging at home, differently at a public car charging station, and differently on the road at fast chargers. According to European Commission JRC materials from 2024 and industry organization studies, charging at home or at work is usually the cheapest, while fast charging on the road is the most expensive, especially with high rates for energy and dwell time.
If an electric car uses about 16 kWh per 100 km, then at an electricity price of PLN 1.00 per kWh, the cost of driving 100 km is about PLN 16. At PLN 1.80 per kWh, it becomes PLN 28.80. This can still be favorable compared with gasoline or diesel, but only if you plan electric car charging consciously. In practice, charging losses, driving style, temperature, and route also matter. In winter, range and energy consumption can change, so it’s worth leaving room in the budget.
If you’re considering buying an EV, check not only the catalog range, but also real access to infrastructure. Search for a car charging station near your home, work, and most common routes. A well-planned charging network reduces stress and helps avoid expensive emergency stops at fast chargers.
New car, used car, and leasing, where costs surprise the most
A new car gives you predictability, but it usually loses value sharply in the first few years. With a used car, it’s the opposite: the purchase price is lower, but repairs and wear are a bigger risk. Car leasing, in turn, organizes expenses into a monthly payment, but it does not remove the need to calculate the total cost of use, mileage limits, additional fees, and return conditions.
When you analyze car leasing, pay attention to the down payment, the buyout amount, insurance, mandatory servicing, and usage restrictions. A low installment does not always mean a cheap car. Sometimes it only means postponing costs over time. If you’re looking at a car launch or following a car review, remember that marketing usually highlights the benefits and does not show the full cost of ownership.
Car test and car test drive, what to check before deciding
A good car test drive and a reliable car test help you assess not only comfort, but also potential expenses. Pay attention to brake performance, suspension condition, visibility, noise, ergonomics, and fuel or energy consumption. In a used car, listen for sounds from the gearbox, suspension, and air conditioning area, because even minor symptoms can mean later bills.
A practical pre-purchase checklist can look like this:
- Check the service history and mileage.
- Compare real fuel or energy consumption with the manufacturer’s data.
- Calculate insurance, tires, inspection, and expected servicing.
- Take a car test drive in the city and outside the city.
- Compare several offers, also through a car configurator, if you are choosing a new car.
With a new car, the car configurator helps determine how much the price rises after adding truly needed elements. This is exactly where you can see that car equipment can significantly increase the installment or final price. Air conditioning, driver assistance systems, better lights, safety packages, or larger alloy wheels are convenient, but not always necessary.
The most common mistakes when calculating costs
The most typical mistake is focusing only on fuel or the payment. The second mistake is failing to include depreciation. The third, very common one, is omitting servicing and tires. That’s why it’s worth keeping a simple expense record, even in a spreadsheet or a mobile app. When you see the full picture, it’s easier to decide whether it’s better to buy a newer, less troublesome car or a cheaper example with a higher repair risk.
In practice, the drivers who save the most are those who regularly check tire pressure, don’t delay inspections, drive smoothly, and compare insurance offers. These are not spectacular tricks, but they are what most effectively lower car ownership costs over the course of a year.
How to budget for a car wisely
If you want to act sensibly, start with an annual plan. Enter the expected mileage, average fuel or energy consumption, the cost of insurance, inspection, seasonal tire changes, and servicing. Then add a margin for unexpected expenses, ideally 10 to 15 percent. Such a buffer gives you greater peace of mind, especially when you’re buying a car for the first time or considering moving to a different segment.
It’s also a good habit to compare several models not only by purchase price, but by how much they cost over three or five years. Then a car launch no longer tempts you with novelty alone, and a car review becomes a starting point, not the only basis for a decision. If you use a car configurator, test both the base version and the version with extras, because the difference can be greater than it first appears.

FAQ
How much are the basic costs of car ownership?
It depends on the model, mileage, and driving style, but in practice you need to include fuel or energy, insurance, servicing, tires, inspections, and depreciation. The payment itself or the fuel price does not show the full picture.
Is an electric car always cheaper to run?
Not always. Charging an electric car at home can be cost-effective, but fast charging on the road can be expensive. It’s worth calculating your own driving profile and access to infrastructure.
What should you watch out for when buying a used car?
Check the service history, technical condition, mileage, tires, brakes, and the real cost of parts. A used car purchase can be worthwhile, but only if the car’s condition is properly assessed before signing the agreement.
Does car leasing reduce costs?
Leasing can make it easier to plan a monthly budget, but it does not automatically mean the lowest total cost. Always check additional fees, mileage limits, and buyout conditions.
