I am trying to calculate the average decline rate (% change) through months and years using:
Avg. Liquid (mboepd):=AVERAGEX(oga_data, oga_data[Liquid (mbopd)])
and
Liquid Decline:=
VAR __LiquidPriorMonth = CALCULATE([Avg. Liquid (mboepd)], PARALLELPERIOD('Calendar'[Date], -1, MONTH))
RETURN
DIVIDE([Avg. Liquid (mboepd)] - __LiquidPriorMonth, __LiquidPriorMonth)
The monthly decline calculates as expected but the subtotals are not correct.
Could sombody please explain where I am going wrong?
Solved! Go to Solution.
Keep your existing measures, but use a measure like this in your visual (assume you have a column called YearMonth in your Date table).
NewMeasure = AverageX(Values(Date[YearMonth]), [Liquid Decline])
This should work both for your rows and subtotal.
If this works for you, please mark it as solution. Kudos are appreciated too. Please let me know if not.

Thanks - that works as expected to get % change by month on the rows and an average of the % change for the year in the subtotals.
Could you also tell me if it's possible to keep % change by month on the rows and get a % change for each year for the subtotals?
This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376
