Calculate annual, monthly, weekly, and daily fuel costs, gallons or liters used, or solve for distance, MPG, L/100 km, and fuel price.

Money is in USD. Unit changes convert quantities; no exchange-rate conversion is applied.

Annual Fuel Cost Formula

The following formula could be used to calculate your annual fuel cost of driving.

C = M / mpg × g
  • Where C is your annual fuel cost
  • M is the total yearly mileage
  • mpg is the miles per gallon your car gets
  • g is the average cost of a gallon of gas

To calculate annual fuel cost in US units, divide yearly miles by US miles per gallon, then multiply by USD per US liquid gallon. In metric units, multiply kilometers by L/100 km, divide by 100, then multiply by USD per liter. Unit changes convert quantities; weekly and daily figures are averages based on 365 days.

Annual Fuel Cost Definition
