Average & Weighted Average - help needed

Hi Community

I'm seeking help with calculating an average and weighted average in my Power BI model.  The excel file below shows what I'm trying to achieve.  Thanks in advance for any guidance you can offer.

Re: Average & Weighted Average - help needed

The first thing I thought when I saw the data was "well, we've got to unpivot those columns" and then I looked at the transforms and see that they had just been pivoted.  So, remove that step.

You could split the 'Nominal - Dec' to get a column that indicates job role e.g. Graduate.

The 'CY Total' can then become

``CY Total = CALCULATE(SUM(TableSalary[Base Amount]), TableSalary[Accounting Period] = "2019/001")``

and PY Total can be re-written similarly.

%Increase can stay.

Weighted average would be

``Weighted Av = [% Increase] * [CY Total]``

You can pull all the relevant fields into a matrix with 'job role' in the column and employee in the rows.

All the Totals and sub-totals will give you the figures you want.

Alternatively, to see the data in more compact form, create two tables 1 - Role, weighted av, % increase

2 - Employee, Role, all the measures

------------------------------

For a more complex data set, you could implement the measures using time intelligence rather than filtering the table with hardcoded years i.e. "2019/001"

Hope that helps.

Hey @HotChilli

I can't thank you enough. Your suggestions were spot on, nailing my issues right there.  can I be super cheeky and ask for your help again with the weighted average?  This formula:

`Weighted Av = [% Increase] * [CY Total]`

actually gives the answer to my NI/Share Profit calculation.  Is the Weighted Average in my Excel file doable?

Thanks!
