How to Calculate MPG in Excel – 5 Steps

What Is MPG?

MPG, or miles per gallon, is the distance measured in miles a car can drive per gallon of gasoline.

The dataset below showcases a Milage Log of 10 days in May 2022.

Column B contains the Date, column C includes Odometer Readings, column D shows Distance Travelled (in Miles), and column E the Fuel Consumption (in Gallons).

The mathematical formula to calculate MPG is:

MPG = Total Distance Travelled / Total Fuel Consumed

Step 1 – Determine the Distance

• Subtract the odometer reading of the previous day from the odometer reading of the current day to get the mileage. Here, C11 is subtracted from C12:

• Drag down the Fill Handle to see the result in the rest of the cells.

Step 2 – Calculate the Daily MPG

• Select F11 and enter the formula below.
• Press ENTER.

• Drag down the Fill Handle to see the result in the rest of the cells.

Step 3 -Find the Total Distance and Total Fuel Consumption

• Select D16 and enter the formula below in the Formula Bar.
• Press ENTER.

The SUM function is used in D11:D15.

Step  4 – Calculate the Average MPG

• Select D17 and use the formula below.
• Press ENTER.

Step 5 – Calculate the Average MPG Using the AVERAGE Function

An alternative to determine the Average MPG is to average the daily MPG values in F11:F15.

• Select F17, and enter the formula below.
• Press ENTER.

The AVERAGE function calculates the Average MPG in F11:F15.
