Gas cost calculator
The following gas cost calculator will help you determine three things: annual gas cost, monthly gas cost, and miles per gallon (MPG)
Guidelines to follow when using the gas cost calculator
When entering numbers, do not use a slash: "/" or "\"
Daily mileage: It is the number of miles you drive your car daily. Just enter an estimate.
Cost per gallon: It is what you pay at the gas pump to put gas in your car.
Gas tank size: How many gallons of gas can your tank hold when it is full?
Days between fillups: How often do you fill your tank? Is it every 2 days, 3 days, 4 days.....? I fill mine every 6 days.
Take a look at the figure below to see an example of how to enter number.
Suppose you enter the following information into the calculator:
- Daily mileage is 50
- Cost per gallon is 3
- Gas tank is 18
- Days between fillups is 6
The gas cost calculator will display the following information:
- The miles per gallon is 16.66
- The annual gas cost is 3285 dollars
- The monthly gas cost is 273.75 dollars
