I am working on an Executive db of financial ratios. One of the ratios is "return on assets"....Both are EBITDA and Total Assets are Calculated fields.
EBITDA / Total Assets
EBITDA - would use a prior rolling 12 month range
Total Assets - Would use the last date in the range.
and I'm always calculating it at the end of a month....
So, if I want to calculate the "Return on Assets" for 3/31/2016
EBITDA (would be monthly EBITDA from April 1, 2015 - March 31, 2016
Total Assets (@ 3/31/2016)
So, if I want to calculate the "Return on Assets" for 1/31/2016
EBITDA (would be monthly EBITDA from February 1, 2015 - January 31, 2016
Total Assets (@ 1/31/2016)
My thoughts are to create a Calculated Field on 12 Month Rolling EBITDA and a Prior Month Total Assets and then divide the 2.
Prior Month Total Assets Calculated Field:
IF [Dates]=DATETRUNC('month',TODAY())-1 THEN [Total Assets] ELSE 0 END
EBITDA (calc field is)..... [Monthly Net Income]+SUM([Monthly Interest])+SUM([Monthly Taxes])+SUM([Monthly Depreciation])+sum([Monthly Amortization])
Total Assets (calc field is)....CASE [Account Type] WHEN 'ASSETS' THEN [Ending Balance] ELSE 0 END
