Car Running Costs Calculator — Total Cost of Ownership (TCO)

The Total Cost of Ownership (TCO) covers all costs of running a car, not just fuel and insurance. Many drivers underestimate depreciation — typically the largest single cost at 15% of the car's value per year. This calculator includes seven key components: depreciation (15% per year), fuel costs, third-party (OC) and comprehensive (AC) insurance, servicing and repairs, and parking. The result is your full annual and monthly car budget, plus the cost per kilometre driven. Enter your car's value, annual mileage, fuel consumption and local prices to get a complete picture.

How the car running costs calculator works

The calculator divides costs into fixed and variable: Fixed costs (independent of mileage): - Annual depreciation = car value x 15% - Third-party + comprehensive insurance Variable costs (mileage-dependent): - Fuel = (mileage / 100) x consumption x fuel price - Servicing and repairs (annual figure entered) - Parking = monthly rate x 12 Total annual cost = fixed + variable Cost per km = total annual cost / annual mileage Monthly cost = total annual cost / 12 The 15% depreciation rate is typical for 2-5 year old cars. New cars may lose 20-25% in the first year; older cars depreciate more slowly.

Example: car worth PLN 80,000, 20,000 km/year

Car: PLN 80,000. Annual mileage: 20,000 km. Fuel consumption: 7 l/100km. Fuel price: PLN 6.20/l. OC+AC: PLN 3,000. Servicing: PLN 2,000. Parking: PLN 200/month. Depreciation: 80,000 x 15% = PLN 12,000. Fuel: 20,000/100 x 7 x 6.20 = PLN 8,680. Parking: 200 x 12 = PLN 2,400. Total: 12,000 + 3,000 + 8,680 + 2,000 + 2,400 = PLN 28,080/year (PLN 2,340/month, PLN 1.40/km).

Frequently asked questions

How much does it cost to run a car in Poland?

For a PLN 80,000 car driven 20,000 km/year, total running costs are approximately PLN 28,000/year (PLN 2,340/month, PLN 1.40/km). The breakdown: depreciation PLN 12,000, fuel PLN 8,680, insurance PLN 3,000, servicing PLN 2,000, parking PLN 2,400.

What is TCO (Total Cost of Ownership)?

TCO covers all costs of owning a car: fixed costs (depreciation, insurance) and variable costs (fuel, repairs, parking). TCO lets you compare the true cost of different vehicles and evaluate whether ownership vs. leasing makes financial sense.

How is car depreciation calculated?

The calculator uses 15% annual depreciation as a conservative estimate for cars aged 2-5 years. New cars can lose 25-30% in the first year, while older cars depreciate more slowly. Depreciation is the biggest hidden cost for most car owners.

How much is third-party (OC) insurance in Poland?

Third-party (OC) insurance is mandatory in Poland. Cost depends on driving history, age and vehicle — typically PLN 600–1,500/year. Comprehensive (AC) insurance is optional and costs PLN 1,000–3,000/year depending on the car's value. Total OC+AC: usually PLN 1,500–5,000/year.

How does fuel consumption affect running costs?

Fuel is typically 30–40% of total variable costs. The difference between a 5 l/100km and a 10 l/100km car over 20,000 km at PLN 6.20/l is: (10-5)/100 × 20,000 × 6.20 = PLN 6,200/year. Choosing a more economical car can save thousands of PLN annually.

What is the cost per kilometre for a typical Polish car?

For a mid-range car (PLN 50,000-100,000) driven 15,000-20,000 km/year, the all-in cost per km is typically PLN 1.20–1.80. The statutory mileage rate in Poland (2026) is PLN 1.15/km for cars over 900cc — actual running costs often exceed this rate.

Indicative result
