How it is calculated

Battery energy = miles × (kWh per 100 miles) ÷ 100. Because some energy is lost as heat while charging, the energy drawn from the wall is the battery energy divided by the charging efficiency (90% by default).

The cost is the wall energy × your rate. The default rate is the U.S. average residential price of 18.56¢ per kWh from the EIA (March 2026); the state pages use each state’s average.
