Helper II

## Percentage calculated column

Hello!

I need some help with a Profit % calculated column. I think it is a very simple answer that I can't seem to see.

T_Profit = Table1[T_Revenue]-Table1[T_Cost]

T_Profit% = DIVIDE(Table1[T_Profit],Table1[T_Cost],0)

These two columns calculate fine on a row level, however, the Totals do not work, therefore when I try to put a Card visual for the overall T_Profit% is does not work. I don't know how to get the % of the total without it summing or averaging...

Example below

When I pull it into a card I am forced to find a calculation eg. It's either Sum (37.20%) or Average (9.30%) when it should be 12.40% still....

I think perhaps my DAX or my maths is incorrect. Can someone please provide me with a more effective DAX. Should I use a measure instead?

Thanks!

Yes, you should use measures instead. When you add a column to a visual like that Power BI will automatically create implicit measures anyway, better to do it yourself. You can also use the measures you define as building blocks for further measures, e.g.

``````Revenue = SUM(Table1[T_Revenue])

Cost = SUM(Table1[Cost])

Profit = [Revenue] - [Cost]

Profit % = DIVIDE( [Profit], [Cost], 0)``````
