About this tool

Enter the distance you drive each year, your car's efficiency in miles per kWh and the price per kWh. The calculator shows the kWh used, the yearly and monthly charging cost and the cost per mile.

How it is worked out

Energy use is distance divided by efficiency. Most electric cars achieve 3 to 4 miles per kWh in mixed driving. Cost is kWh times the price you pay, which is lower at home overnight and higher at public rapid chargers.

Example

12,000 miles at 3.5 miles per kWh is about 3,430 kWh, which costs about $549 a year at $0.16 per kWh, or 4.6 cents a mile.

Tips

Charging losses add about 10 percent between the wall and the battery, so use a slightly lower efficiency for a safe estimate. Time-of-use tariffs can cut the home price by half.

计算示例

With the boxes at their starting values (Distance per year (miles): 12000; Efficiency (miles per kWh): 3.5; Electricity price per kWh: 0.16), the tool shows: Energy used (kWh): 3,429; Cost per mile: 0.046; Cost per month: 46; Cost per year: 549.
