How it is calculated

kWh from the outlet = miles ÷ miles per kWh ÷ (1 − charging losses). Charging cost = kWh × electricity price.

Gas cost = miles ÷ mpg × gas price. The difference is what you would save (or spend) by charging at home instead of buying gas.

Worked example

With the starting values shown in the form (U.S. average price of 18.16¢ per kWh), the result is $57.65 (home charging per month). Change any number and the estimate updates as you type.

Questions

How many kWh does it take to drive 100 miles?
At 3.5 miles per kWh, about 28.6 kWh reaches the battery, or about 31.7 kWh from the outlet with 10% charging losses.
Is charging at home always cheaper than gas?
At typical U.S. home electricity prices it usually is, but in states with very high rates and for very efficient gas cars the gap narrows. The calculator shows your own numbers.
