Quick answer
1,000 miles/month at 30 kWh/100mi and 16¢/kWh costs $48 — versus about $117 in a 30-MPG gas car at $3.50/gal.
How it works
Electric driving cost depends on your car's efficiency and your electricity rate. Home charging at average US rates is usually far cheaper per mile than gasoline.
Formula
EV cost = (miles ÷ 100) × kWh per 100 mi × rate. Gas cost = (miles ÷ MPG) × price per gallon

Frequently asked questions
What about public fast charging?
Fast chargers often cost 2–3× home rates. Enter that higher rate to see the difference.
Where do I find my efficiency?
Your car's dashboard shows kWh/100mi; most EVs fall between 25 and 35.
