How to Use Tesla Charging Cost Calculator
The Tesla Charging Cost Calculator computes both the kWh required and the dollar cost for any trip.
- Select Your Tesla Model — Model 3, Model Y, Model S, Model X, or Cybertruck.
- Enter Distance — Total miles or kilometers for the trip.
- Enter Electricity Price — Cost per kWh from your utility bill or supercharger receipt.
- Optional: Adjust Loss % — Default 10% covers AC home charging losses.
- Read the Output — kWh used, total cost, and cost per mile.
Formula & Theory — Tesla Charging Cost Calculator
energy = distance × efficiency_per_mile
energy_after_loss = energy ÷ (1 - loss%)
total_cost = energy_after_loss × price_per_kWh
cost_per_mile = total_cost ÷ distance| Symbol | Meaning |
|---|---|
| efficiency_per_mile | kWh consumed per mile |
| loss% | Charging losses (AC ~10%, DC ~5%) |
| price_per_kWh | Local electricity / supercharger price |
| total_cost | Total dollars to charge |
Typical Tesla Efficiency
Model 3 ≈ 0.25 kWh/mi
Model Y ≈ 0.26 kWh/mi
Model S ≈ 0.31 kWh/mi
Model X ≈ 0.34 kWh/mi
Cybertruck ≈ 0.40 kWh/miCold weather can increase consumption by 20–40%; high-speed highway driving (75+ mph) adds another 10–15%.
