Do calculation on cell level

Hi kalpanaV,

You should use a iterator function like SUMX to do row based calculations. 

The formula might need a little change because only in the third row i see you divide the result by 3*12 and because there is no desired result please check if the formule is fully correct.

First define a measure that counts the V column as a running total, I called it YTD but actually it uses the Index now. Consider using a date column so you could use an actual YTD function. Below the V_YTD and calculation like described.

V_YTD = 
VAR CurrentIndex = MAX('Table'[Index])
RETURN
CALCULATE( SUM('Table'[v]);
	FILTER(
		ALLSELECTED('Table');
		'Table'[Index] <= CurrentIndex
	))

NewCalc = 
VAR V = SUM('Table'[v])
VAR HC = SUM('Table'[HC])
VAR V_YTD = [V_YTD]
RETURN
SUMX(
	'Table';
	(V_YTD/HC)/'Table'[Index] * 12)

Result:
