Fuel and charging costs: how to compare

Gas, hybrid and electric running costs, worked out with your own numbers.

5 min read

Fuel costs depend on three numbers: how far you drive, how efficient the car is, and what you pay for fuel or electricity. Use your own numbers, not national averages.

Gas and hybrid

Yearly fuel cost = miles per year ÷ combined MPG × price per gallon. The EPA's fueleconomy.gov lists official ratings for most cars.

Electric

Yearly charging cost = miles per year ÷ miles per kWh × price per kWh. Home charging is usually cheaper than public fast charging; use the rate on your electricity bill and a realistic share of public charging.

Things that change the math

  • Cold weather and highway speeds reduce efficiency, especially for EVs
  • Premium fuel requirements
  • Whether you can charge at home
  • Local fuel and electricity prices
