Annual cost divides your mileage by real-world miles per kWh, then applies the selected electricity rate. The journey estimate uses distance, starting charge, desired arrival charge and your home/Supercharger mix.
Charging-stop counts assume roughly 55% battery is added at each stop. They are a useful comparison, not a route plan: use Tesla navigation for live weather, elevation, traffic and charger availability.

At 4.1 mi/kWh and 26.32p/kWh, electricity costs about 6.4p per mile. A 60kWh 0–100% charge is about £15.79 before charging losses.
A 360-mile return journey at 3.7 mi/kWh needs about 97kWh. Change the starting charge and charging mix to estimate cost and likely rapid-charging stops.
At the Ofgem price cap average of 26.32p/kWh (Q4 2026), charging a Tesla Model Y Long Range (77 kWh battery) from 0–100% costs around £20.27. On an EV tariff (6–9p/kWh overnight from Octopus, E.ON or British Gas), it drops to just £5–£7. Annual home charging costs roughly £740 per year at the standard rate for a driver covering 200 miles per week.
Tesla Supercharger pricing in the UK uses two time bands and two tiers. Members (£9.99/month) pay 25p/kWh off-peak (11PM–9AM) and 41p/kWh peak (9AM–11PM). Non-members pay 35p off-peak and 60p peak.
Home charging is cheaper, especially on an EV tariff. At 7–9p/kWh overnight vs 41–60p/kWh at a peak Supercharger, home charging on an EV tariff costs a fraction of the price. Even at the Q4 2026 standard rate average (26.32p/kWh), it's cheaper than peak Supercharging.
For a Tesla Model Y (3.7 miles/kWh efficiency) charged at home (26.32p/kWh), the cost is approximately 7.1p per mile. On an EV tariff (7p/kWh), it's around 2p per mile. At a peak Supercharger (41p/kWh member, 60p non-member), it's around 11–16p per mile. Compare this to a petrol car at 35 mpg costing approximately 21p per mile at current prices (158p/litre).
