How much do you save with a Tesla: average figures
Before you run your own numbers, here’s what the calculator shows for a typical driver at 15,000 km per year, using current fuel and electricity prices:
| Electric (Tesla) | Petrol (1.5L) | |
| Cost per km | €0.030 | €0.113 |
| Annual fuel cost | €456 | €1,701 |
| Annual service | €200 | €500 |
| Annual total | €656 | €2,201 |
| Annual saving | €1,545 | — |
| 5-year saving | €7,725 | — |
Fuel prices sourced from fuel-prices.eu and electricity tariffs from Eurostat. Tesla Supercharger rates from Tesla.
That’s €1,545 per year — or €7,725 over five years — staying in your pocket instead of going to the pump and the garage.
But your number will be different
The table above is an average. Your actual saving depends on three things:
- How many km you drive per year — more km means bigger savings
- Your home electricity tariff — use the rate from your bill, not a national average
- How often you use Superchargers vs charging at home
A driver doing 30,000 km/year saves over €3,000 annually. A driver doing 10,000 km/year saves around €800. Enter your real numbers in the calculator to get your personal figure.
