How to Calculate Running Average in Excel (3 Ideal Examples)

Example 1 – Calculating Regular Running Average with Excel AVERAGE Function

STEPS:

• Select cell D5 and enter the AVERAGE function.
`=AVERAGE(\$C\$5:C5)`
• Cell C5 is used as the argument of the AVERAGE function.
• To make the C5 reference an absolute reference, press the F4 key on your keyboard.
• Cell reference C5 turns into an absolute cell reference.
• Enter the range operator and enter the C5 cell reference.
• Place the closing parenthesis after the formula.

• Press Enter.
• The formula returns a value of 2901. This formula actually finds out the average of cell C5.
• Select the cell and copy the formula for the next cell.

The formula returns 3022.5.

• Select the cell and click on the formula bar.

You see this formula selects cells C5 to C6. So the formula calculates the average of cells C5 to C6.

Example 2 – Calculating 3 Months Running Average in Excel

STEPS:

• Under the 3-month Running Average column, select the third cell E7. As we are going to find out the running average of 3 months, we have to start from the third month. You cannot find out 3-month running averages using only 1 or 2 values. The formula is:
`=AVERAGE(C5:C7)`
• Enter the average function in cell E7, select cells C5 to C7. This time I am not going to turn any cell references to absolute as when I copy this formula to the cells below, I want every formula will select the last three values.
• Close the function and press Enter.

• The formula returns 3202. It is the same as this running average. The reason is this running average finds out the average of these three values and this 3-month running average also does the same.
• Copy the formula to other cells in the column.
• You’ll get all the 3-month running averages.

Example 3 – Inserting Excel SUM Function to Determine Running Average

STEPS:

• Select cell D5.
• Enter the following formula:
`=SUM(\$C\$5:C5)/COUNT(\$C\$5:C5)`

NOTE: SUM(\$C\$5:C5) returns the sum of C5:C5. The COUNT(\$C\$5:C5) formula returns the number count, which is 1.
• Press Enter.
• Use AutoFill to fill in the rest.
• It will return the running averages in cells D5 to D16.
