Analysis :: Annualized Amount Based On Completed Quarters

I would like to add a calculation to provide an annualized Gross Amount value.  Most solutions I have seen are for annualizing down to the day.  For instance, if today is the 123rd day of the year, the calculation would be Amount / 123 * 365.  What I want to do is annualize the amount based only on completed periods.  Today is 8/26.  

The last completed quarter ended on 6/30.  Therefore I want to basically take the sum of Q1 and Q2, divide by two, and multiply by four to get an annualized amount based on completed quarters.  Eventually I want to do something similar with months.

So here's what I have so far.  In my DSV my DimDate is actually based on a view.  The view has a Date column with the actual date, all of the normal fields you would expect in a DimDate table, and two columns that look like this:

CASE
WHEN [Date] < DATEADD(QQ, DATEDIFF(QQ, 0, GETDATE()), 0)
THEN 'Y'
ELSE 'N'
END AS
CompletedQuarter,

[Code] ....

Note that for dates between 1/1 and 3/31 the CompletedQuarterCount will be 0.  I want any annualized amount to be 0 in that case because I only want to use completed quarters in my calculation.

I added both to my Pay Date dimension (which uses vwDimDate from the DSV) in the cube.  I have tried the calculation below and in my Excel pivot table I'm getting blanks for the calculated field.

CREATE MEMBER CURRENTCUBE.[Measures].[Gross Amount Annualized by Pay Date Quarter]
AS SUM(
IIF([Pay Date].[Pay Date Completed Quarter Count] > 0,
[Gross Amount] / [Pay Date].[Pay Date Completed Quarter Count] * 4,
0)
),
FORMAT_STRING = "Currency",
VISIBLE = 1 , ASSOCIATED_MEASURE_GROUP = 'Fact Claim' ;

So, is my calculation correct?
