Hi All,

I am stuck on a problem and it has to do with replicating a specific formula in excel in power query.

The main challenge here is using the cumulative answer within the calculation if that makes sense.

I have attached my sample file below and it will much clearer what I am trying to achieve.

If you open this file and go to the tab “What I am trying to achieve” you will see the formula in Cell Q8. I am stuck on the cumulative addition per month part of this formula as I don’t know how to achieve this in power query.

If you go to power query in the last step Employer CPP costs in the salary table that is where I have done my m code calculations but quite clearly I don’t know how to include my answer as a cumulative total in the calculation and hence stuck.
