subtract values across a row when there's multiple items in first column

[cdunworth]

I have a tablethat looks like below: 

I need to sum the Total Starting Spread column for each unique Recrutier and subtract that value from the Avg Spread Column. Below is the DAX i'm currently using but I'm not getting the correct answer. What do I need to do from there to get this figured out? 

Spread)Diff = AVERAGE('Starting Spread Goals'[CandidatesInConsideration.Total Starting Spread])-'Starting Spread Goals'[Avg Spread]

Hi @cdunworth,

You can try to use below formula to get the diff of grouping average and current 'avg spread'.

Calculate column:

Spread Diff =
AVERAGEX (
    FILTER (
        ALL ( 'Starting Spread Goals' ),
        [Recrutier] = EARLIER ( 'Starting Spread Goals'[Recrutier] )
    ),
    [CandidatesInConsideration.Total Starting Spread]
)
    - 'Starting Spread Goals'[Avg Spread]

Hi,

Drag Recruiter to the visual and write this calculated field formula i.e. measure

=SUM('Starting Spread Goals'[CandidatesInConsideration.Total Starting Spread])-MIN('Starting Spread Goals'[Avg Spread])
