Formula and boundaries
Gasoline: annual miles ÷ official combined MPG × price per U.S. gallon. Electricity: annual miles ÷ 100 × official combined kWh per 100 miles × price per kWh. The difference is one estimate minus the other.
The comparison covers energy only. It excludes purchase price, taxes, financing, insurance, maintenance, charging losses, public charging premiums and fuel-price changes. Plug-in hybrids and dual-fuel records need a more specific share-of-driving assumption, so treat their result as a planning estimate.
