Hi LeanneShapro

You could create measures

Measure = CALCULATE(COUNT(Table1[name]),FILTER(ALL(Table1),[score]>8))

Measure 2 = CALCULATE(COUNT(Table1[name]),FILTER(ALL(Table1),[score]<7))

Measure 3 = CALCULATE(COUNT(Table1[name]),ALL(Table1))

Measure 4 = ([Measure]-[Measure 2])/[Measure 3]

Measure 5 = ROUNDUP([Measure 4],0)

Or a nested measure

Measure 6 =
VAR low =
    CALCULATE ( COUNT ( Table1[name] ), FILTER ( ALL ( Table1 ), [score] < 7 ) )
VAR high =
    CALCULATE ( COUNT ( Table1[name] ), FILTER ( ALL ( Table1 ), [score] > 8 ) )
VAR alname =
    CALCULATE ( COUNT ( Table1[name] ), ALL ( Table1 ) )
VAR percentage = ( high - low )
    / alname
RETURN
    ROUNDUP ( percentage, 0 )

Hi v-juanli-msft - 

 

I appreciate you sharing your recommendation. 

 

I entered the following formula per your suggestion: 

 

NPS = VAR low =
CALCULATE ( COUNT ( 'GetFeedback Result'[Likely to Recommend - RNPS] ), FILTER ( ALL ( 'GetFeedback Result' ), [Likely to Recommend - RNPS] < 7 ) )
VAR high =
CALCULATE ( COUNT ( 'GetFeedback Result'[Likely to Recommend - RNPS] ), FILTER ( ALL ( 'GetFeedback Result' ), [Likely to Recommend - RNPS] > 8 ) )
VAR alname =
CALCULATE ( COUNT ( 'GetFeedback Result'[Likely to Recommend - RNPS] ), ALL ( 'GetFeedback Result' ) )
VAR percentage = ( high - low )
/ alname
RETURN
ROUNDUP ( percentage, 0 )

 

When I added the measure as a Card on my dashboard, it came out as a -1. When I used my excel formula, it resulted the value -33, which is accurate. 

 

Do you have further recommendations for me? 

 

Thanks in advance, 

 

Leanne
