## DAX calculation help!

Hello!

I'm hoping somebody can point me in the right direction with a DAX query that I need to be able to solve but can't quite get me head around.

We have a fact table at a day granularity where a product has total cost and revenue metrics. I need to be able to calculate a margin share of the total cost i.e. revenue/total cost and then share the margin between two partners based on rules.

Partner A must get at least 20% margin.

Partner B then gets anyting over 20% margin up until 40%

The margin over 40% is shared equally by A & B

So, for example:

Product A on Jan 1 2024 has TotalCost 1000 and Revenue 300 = 30% margin

Partner A gets  200, Partner B gets 100

Product B on Jan 1 2024 has TotalCost 1000 and Revenue 390 = 39% margin

Partner A gets  200, Partner B gets 190

Product C on Jan 1 2024 has TotalCost 1000 and Revenue 400 = 40% margin

Partner A gets  200, Partner B gets 200

Product D on Jan 1 2024 has TotalCost 1000 and Revenue 540 = 54% margin

Partner A gets  270, Partner B gets 270

Any guidance or help on this would be very much appreciated!

Thanks

Hi @mlmchilli ,

First of all, many thanks to @lbendlin  for your very quick and effective replies, and I will give some additions below:

1.Create the sample table.

2.Create the new measure to calculate the margin share.

``````Margin Share =
var partn_ = SELECTEDVALUE('Table'[Partners])
VAR Margin = DIVIDE(SUM('Table'[Revenue]), SUM('Table'[Total cost]))
VAR BaseMargin = 0.2
VAR UpperMargin = 0.4
VAR ExcessMargin = MAX(0, Margin - UpperMargin)
VAR SharedExcess = ExcessMargin / 2

RETURN
IF(partn_ = "A",
IF(Margin <= 0.4, BaseMargin * SUM('Table'[Total cost]), BaseMargin * SUM('Table'[Total cost]) + SharedExcess * SUM('Table'[Total cost])),
IF(Margin <= 0.4, (Margin - BaseMargin) * SUM('Table'[Total cost]), BaseMargin * SUM('Table'[Total cost]) + SharedExcess * SUM('Table'[Total cost]))
)
``````

3.Drag the measure into the table visual. The result is shown below.

Best Regards,
