Compact Cars — EPA rates this 2027 Rolls-Royce Spectre at 324 miles of range and 42.2 kWh per 100 miles, measured at the wall. A full charge therefore draws about 136.6 kWh from the meter, which is 10–15% more than the battery holds, because charging is not perfectly efficient.

Assumptions: 12,000 miles a year, home Level 2 charging, and EPA combined consumption measured at the wall (so charging losses are already included). Gasoline comparison uses $3.50 a gallon at 30 MPG. Change any of these in the calculator.
