Calculate YTD total when monthly costs change

[Anonymous]

I'm  trying to create a measure that will calculate total cost per contact by month. Trouble is, the CPC changes MoM, so the measure needs to be a bit dynamic. At this point, I've created a simple table that has the CPC by month and written the following: 

Monthly Estimated Savings = CALCULATE([Estimated Deflections] * SELECTEDVALUE('Consumer Cost Per Call'[Cost Per Call],0) 

The Cost per Contact table looks like this: 

Date	Cost per Contact
Jan	7.02
Feb	7.34
Mar	6.80
Apr	6.84

This works fine when the Date is provided as the Filter Context. However, if I try to put this measure in a gauge visual so that the total savings is displayed, I get nothing, presumably due to the fact that there isn't a filter context being provided. 

My question is (A) is there a better way to write the first measure? and (B) if not, how do I get the totals to display? I need to have the sum of the Estimated Savings for a number of visuals, so just having the amount in a matrix won't suffice. Any help would be much appreciated!

hi  @Anonymous 

This looks like a measure totals problem. Very common. See this post about it

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

For your case, just create a new measure like this

New measure=SUMX(VALUES('Date'[Month]),[Monthly Estimated Savings])

or

New measure =
VAR __table = SUMMARIZE('Date',[Year],[Month],"__value",[Monthly Estimated Savings])
RETURN
SUMX(__table,[__value])
