Calculate percentage breakdown of items in a list
For example, I have a statistics report which lists the option answer of each student, and now, I want a percentage breakdown of each option. It means that I need to know the percentages that the options A, B and C account for all options. In Excel, the COUNTIF and COUNTA functions can be combined to calculate the percentage of a specific value in a list of data.
Calculate percentage breakdown of items in a list
If you want to do such a percentage breakdown in Excel, you can apply the COUNTIF and COUNTA functions together, the generic syntax is:
- range:The data range that contains all the options including the criteria;
- criteria: The cell containing the specific value that you want to get its percentage.
1. To count the percentage of each option in the list, please apply the below formula into a blank cell:
2. Then, drag the fill handle down to the cells to apply this formula, and you will get some decimal numbers as following screenshot shown:
3. Select the formula cells, and then click Home > Percent Style to convert the decimals to percentages, see screenshot:
Explanation of the formula:
=COUNTIF($B$2:$B$13,D2)/COUNTA($B$2:$B$13)
- COUNTIF($B$2:$B$13,D2)): This COUNTIF function counts the number of cell D2 in the list of B2:B13, the result is: 3.
- COUNTA($B$2:$B$13): This COUNTA function counts the total number of the cells in the list B2:B13, it returns the result: 12.
- COUNTIF($B$2:$B$13,D2)/COUNTA($B$2:$B$13)=3/12: Finally, the COUNTIF result is divided by the COUNTA result to get the percentage result.
Relative function used:
- COUNTIF:
