How this is calculated
Charging cost is calculated from the energy needed to cover your miles, adjusted for charger efficiency losses.
Energy drawn from wall = (Miles ÷ Efficiency) ÷ Charger efficiency
Daily cost = Energy drawn × Rate per kWh
Example (miles mode): (37 miles ÷ 4 mi/kWh) ÷ 0.90 × $0.1745 = $1.80/day
Example (battery mode): 75 kWh ÷ 0.90 × $0.1745 = $14.54 per full chargeAssumptions
- Miles mode: you drive the entered distance every day of the year
- Battery mode: you charge from 0% to 100% (full cycle) — actual charging is typically 20–80%
- Charger efficiency accounts for AC–DC conversion losses
- Rate is flat — no time-of-use or tiered pricing applied
- Monthly cost = daily cost × 30.44 (average days per month)

Frequently asked questions
How much does it cost to fully charge an EV at home? ▾
For a typical 75 kWh battery (e.g. Tesla Model 3 Long Range) at the US average rate of $0.1745/kWh, a full charge costs approximately $13–$14. With a Level 2 charger at 90% efficiency, you draw about 83 kWh from the wall.
What is charger efficiency and why does it matter? ▾
Chargers are not 100% efficient — some energy is lost as heat during the charging process. A Level 1 (120V) charger is typically 85–88% efficient. A Level 2 (240V) charger is typically 88–92% efficient. This means you pay for slightly more electricity than goes into the battery.
Is it cheaper to charge at home or at a public charger? ▾
Home charging is almost always cheaper. The US average home rate is around $0.1745/kWh, while public Level 2 chargers average $0.20–$0.35/kWh and DC fast chargers can reach $0.40–$0.60/kWh. Charging at home overnight on off-peak rates can be even cheaper.
How does EV charging compare to the cost of petrol/gasoline? ▾
At $0.1745/kWh and 4 miles/kWh efficiency, the cost per mile is about $0.044. At $3.50/gallon with a 30 mpg car, the cost per mile is about $0.117 — nearly three times higher. Exact savings depend on your local electricity and fuel prices.
