The formula
cost per mile = $ per kWh × (kWh per 100 mi ÷ 100). Most Model 3 and Model Y trims are rated around 25–30 kWh per 100 miles on fueleconomy.gov; real-world use is higher in winter and at highway speeds. At home, add roughly 10% for charging losses.
Supercharger prices in 2026
- Tesla owners (member rate): about $0.43/kWh on average across US sites in August–October 2026, per DCFC Tracker's sync of Tesla's public pricing.
- Non-Tesla EVs without membership: about $0.60–$0.62/kWh; Tesla's $12.99/month membership gives them the owner rate.
- Location and time: rates range from about $0.41 (Nebraska) to $0.84 (Hawaii); many sites are 25–35% cheaper off-peak.
- Idle fees apply if you stay plugged in after charging at a busy site. Always check the price in your car's navigation before you go.

How to pay less
- Charge at home for daily driving; save Superchargers for trips.
- Supercharge off-peak when you can (the price shows in navigation).
- Arrive low and leave around 80%: charging is fastest at low charge, so you spend less time per mile added.
- Use the car's trip planner so it preconditions the battery on the way, which makes charging faster.
