Quick Answer
$30–$80/month
Varies by equipment & usage
EV charging cost depends on how many miles you drive, how efficient your vehicle is (measured in kWh per 100 miles or miles per kWh), and your electricity rate. The formula: (annual miles ÷ miles per kWh) × $/kWh = annual cost.
For example: 12,000 miles/year ÷ 3.5 miles/kWh × $0.16/kWh = $549/year, or about $46/month. Efficiency varies by vehicle — compact EVs average 3.5–4.5 miles/kWh, while larger trucks and SUVs may get 2–2.8 miles/kWh.
If you charge at a public Level 3 fast charger (typically $0.30–$0.60/kWh), costs are 2–4x higher. Home Level 2 charging (240V) is the most cost-effective option for daily use.

Home electricity rate vs. public charging rates
Level 1 (120V) vs. Level 2 (240V) charger — Level 2 is faster but same cost per mile
Climate — cold weather reduces battery range by 10–30%
Driving style — highway vs. city, speed, use of heat/AC
Time-of-use electricity rates (charging at night can cut costs significantly)
Pro Tip
The biggest savings usually come from upgrading the least efficient items first. Use Watt Wisdom to see exactly which loads are driving your bill before spending money on improvements.
