Understanding total cost of ownership
What the tool calculates
TCO (Total Cost of Ownership) adds up everything the car costs while you keep it, not just the dealer sticker price.
- Depreciation: value loss on a typical market age curve (steep in the first 24 months, then slower).
- Energy: (km/year × consumption / 100) × price per litre or kWh.
- Fixed costs: insurance + yearly servicing + the “other” field (parking, tolls, inspection).
The total is shown per year, per month and per kilometre, over the horizon you choose (1 to 10 years).
How to fill it in without mistakes
- Purchase price: new TTC, or current value if you already own the car.
- Age: 0 for a new car. A 4-year-old used car already sits lower on the curve.
- Consumption: your real average, not the WLTP sheet. Add +1 to +2 L/100 km (or +3 kWh) in mixed urban use.
- Servicing: €250–400/year on a recent supermini, €600–900 on a diesel SUV, often less on an EV (no engine oil change).
Purchase €22,000, new car, 6.2 L/100 km at €1.85/L, insurance €650, servicing €320. Energy ≈ €1,376/year. Depreciation over 5 years on the internal curve ≈ €2,550/year. Indicative total ≈ €4,900/year, about €0.41/km. The heaviest item is not petrol, it is lost value.
Purchase €28,000 (after any grant you include in the price), 16 kWh/100 km at €0.18/kWh at home, insurance €580, servicing €180. Energy ≈ €346/year. TCO can fall below petrol if you mainly charge at home — and worsen if most kWh come from a motorway charger at €0.50/kWh. Link this to the trip cost and the charging guide.
