Power Pivot - Calculate difference and % difference
Hi All, i have the below pivot table and want to calculate the difference in avg cost from 2020 to 2021 and the % difference of teh same. in the piviot table source the year is a single column named year and items appear in multiple rows and i have just created a measure in DAX to calculate the average cost and then in the pivot table added year to the columns.
thanks!!
| Item | Average cost 2020 | Average cost 2021 | Variance | % Change |
| A | 10 | 11 | Average cost 2020 - Average Cost 2021 | (Average cost 2020/Average cost 2021)*Average cost 2020 |
| B | 20 | 19 | ||
| C | 30 | 15 | ||
| D | 40 | 50 |
Could get all fancy but if simple one off. Something like this.
Avg2020:=calculate(....,filter(all(table,date),year=2020)
Same for 2021
Difference measure just subtract the two measures. Percent difference measure is divide(difference measure,2020measure)
Hi All
this is what i did eventually:
CALCULATE([Average cost, TableName(column) = "2020"])
CALCULATE([Average cost, TableName(column) = "2021"])
% Difference =
=IF(
OR([Avg Part Cost 2020]<=0, [Avg Part Cost Post 2021]<=0),"na",[Avg Part Cost 2021]-[Avg Part Cost 2020])
