Thank you, I modified the file a bit (added added a date table and updated the measure) and attached it.

Can you share your .pbix file and and example of the expected results?
I have 3 years data, 2017,2018 & 2019 (Jan to Aug figure)
I am trying to achieve an extrapolated value for a period of 12 months
This will give me an extrapolated value from Jan to Dec 2019.
I am able to do it in excel but was wondering if it make sense to achieve in power bi.
Thank you.

To project the amount for 12 months in 2019 for product A wouldn't you want to sum Jan - Aug then divide by 8 the multiply by 12?
total / 8 * 12 Product Jan-19 Feb-19 Mar-19 Apr-19 May-19 Jun-19 Jul-19 Aug-19 Total Projected Product A 23 60 30 99 21 94 55 63 445 667.5 Product B 19 14 71 56 36 25 77 74 372 558 Product C 64 84 24 32 61 36 96 5 402 603 Product 1 30 30 99 21 94 55 63 83 475 712.5 Product 2 71 71 56 36 25 77 74 23 433 649.5 Product 3 24 5 15 52 82 57 74 23 332 498 Product 4 99 83 60 2 1 65 74 23 407 610.5 Product 5 56 23 91 95 72 66 94 55 552 828 Product 6 30 24 24 71 56 36 25 77 343 514.5 Product 7 71 99 99 99 99 99 99 99 764 1146 Product 8 24 56 56 56 56 56 56 56 416 624 Product 9 99 99 99 99 99 99 99 99 792 1188 Product 10 56 56 56 56 56 56 56 56 448 672 How is the number table used?

One of my criteria is that different product has a start date.
So the no. of months to divide is differentis it possible?

We just need to modify the measure a bit to do the correct caluculation.
Value in range = VAR StartDate = FIRSTDATE('Table'[Date]) VAR SelectedNumber = MAX ( SELECTEDVALUE ( Numbers[Number] ) -1, 0) VAR EndDate = DATEADD(StartDate,SelectedNumber,MONTH) RETURN CALCULATE( [Value Amount], ALL ( 'Table' ), DATESBETWEEN( 'Table'[Date],StartDate,EndDate) ) / SelectedNumber * 12
