Tesla Model 3 charging cost: what to expect

Versions and consumption

Reference version: LR · 2020.

What it costs, version by version

Winter and summer: the effect on cost

For the reference version (LR · 2020), in an oceanic climate (western France) and mixed driving: 18.4 kWh/100 km in January, i.e. €3.27 per 100 km off-peak, against 16.3 kWh/100 km in July, i.e. €2.90. Charging therefore costs about 13 % more in January than in July.

Compared with other models

At 16.1 kWh/100 km (reference version), the Tesla Model 3 ranks 32 out of 230 models in the Watt Budget database, from most to least frugal. The median is 18.4 kWh/100 km.

Assumptions

• Consumption: average used in the Watt Budget database for each version (sources: Open EV Data and spec sheets). It may differ from your use.
• Home prices: EDF Tarif Bleu on 1 August 2026, 6 kVA, incl. VAT: off-peak €0.1589 per kWh, standard rate €0.2001 per kWh.
• Rapid charger: €0.49 per kWh, indicative price (it varies by network and subscription).
• Charging losses: 12 % at home (Watt Budget’s automatic estimate for a 6.9 kW charger in mild weather), 5 % at a rapid charger. You pay for more kWh than end up in the battery.
• 10 → 80 % charge: 70 % of the usable battery. Estimated range: 95 % of the usable battery at average consumption.
• Winter and summer: model of the Seasons tab (average monthly temperature, consumption curve), mixed driving, no heat pump.

These are orders of magnitude. Your rates, your car and your trips change the result: the free calculator gives you the price of your own charge.
