Often you may want to average values in Excel based on their color.
For example, suppose we have the following dataset and we’d like to calculate the average value of cells based on the cell colors:
The easiest way to do this is by writing some code in VBA in Excel.
This might seem intimidating if you’re not familiar with VBA but the process is straightforward and the following step-by-step example shows exactly how to do so.
Step 1: Enter the Data
First, enter the data values into Excel:
Step 2: Show the Developer Tab in Excel
Next, we need to make sure the Developer tab is visible on the top ribbon in Excel.
To do so, click the File tab, then click Options, then click Customize Ribbon.
Under the section called Main Tabs, check the box next to Developer, then click OK:
Step 3: Create a Macro Using VBA
Next, click the Developer tab along the top ribbon and then click the Visual Basic icon:
Next, click the Insert tab and then click Module from the dropdown menu:
Next, paste the following code into the module code editor:
Function AvgCellsByColor(CellRange As Range, CellColor As Range) Dim CellColorValue As Integer Dim RunningAvg As Long Dim RunningSum As Long Dim RunngingCount As Long CellColorValue = CellColor.Interior.ColorIndex Set i = CellRange For Each i In CellRange If i.Interior.ColorIndex = CellColorValue Then RunningSum = RunningSum + i.Value RunningCount = RunningCount + 1 End If Next i AvgCellsByColor = RunningSum / RunningCount End Function
The following screenshot shows how to do so:
Next, close the VB Editor.
Step 4: Use the Macro to Average by Color
Lastly, we can use the macro we created to calculate the average of cell values based on color.
First, fill in cells C2:C4 with the colors that you’d like to calculate the average value for.
Then type the following formula into cell D2:
Drag and fill this formula down to each remaining cell in column D and the formula will automatically calculate the average value for each of the cells that have specific background colors:
For example, we can see that the average value of the cells with a light green background is 17.67.
We can confirm this by manually calculating the average of each cell with a light green background:
Average of Cells with Light Green Background: (20 + 13 + 20) / 3 = 17.67.
This matches the value calculated by our formula.
