Excel pivot: Adding a summary percentage
I am working with categorical data - think of a survey with ratings from 1 to 5. In addition to the counts and grand total, I need to be able to add a percentage to summarize the top two categories.
Example (trying to add the %):
| Poor | Fair | Neutral | Good | Excellent | Total | %Top 2 | ||
| Jan | 3 | 3 | 3 | 4 | 4 | 17 | 47% | |
| Feb | 1 | 1 | 4 | 4 | 5 | 15 | 60% | |
| Mar | 2 | 6 | 9 | 17 | 88% | |||
| Apr | 1 | 2 | 2 | 6 | 5 | 16 | 69% | |
| Total | 5 | 6 | 11 | 20 | 23 | 65 | 66% |
My true data includes several nested groupings in the rows, so it would make things much easier if I could add this into the pivot table rather than just having a manual calculation off to the right. That would accommodate new groupings that might appear or expanding/collapsing sub-grouping automatically.
I could easily add a column in my raw data to identify if the rating was in the top categories (1) or not (0). However, I am still unsure how to add it without having it nest within the rating categories. Ideas?

With the AGGREGATE() or the LARGE() function you can display the two top values and sum them up. Then just divide by the sum and make it a percentage.
See also the enclosed document.=SUM(AGGREGATE(14,6,B2:F2,{1,2}))/SUM(B2:F2)It's not a pivot table. I hope you like it anyway.
The LAGRGE() function leads to the same result.
=SUM(LARGE(B2:F2,{1,2}))/SUM(B2:F2)
