Understanding Fuel Costs

Electricity is typically cheaper per mile than gasoline or diesel. However, actual costs depend on local energy prices and vehicle efficiency. Electric vehicles have lower operating costs but higher upfront costs.

Step 2: Vehicle Types

About Vehicle Efficiency

Electric vehicles typically achieve 2-6 miles per kWh. Gas vehicles average 20-35 MPG. Hybrids combine electric and gas efficiency for better overall performance. Diesel vehicles offer better fuel economy but higher fuel costs.

Cost Per Mile Formulas

EV: Electricity Rate ÷ Vehicle Efficiency (miles/kWh)

Gas/Diesel: Fuel Price ÷ Vehicle Efficiency (MPG)

To calculate cost per mile: Divide your energy cost by your vehicle’s efficiency. Multiply by annual mileage to get annual cost.
