Hi All
I'm trying to replicate a calculation I have in excel into Power BI.
Long story short, I have a table which display what the performance is for each month (see screen shots) and a second column YTD where it displays the performance depending on the month.
i.e. If we had 100% in July and 120 % in August, then the YTD column would display 100% for July and 110% for August as August is the sum of July and August percentages divided by 2.
Then if it was september, it would be divided by 3 and so on.
I know how to create this calculation in Excel, but would any of you know how to do in Power BI?

@RodrigoTXRAHere is something I put together to give you an idea, logically you should have a FIscal Date DImension in model for time intelligence and this kind of calculation, but I guess this will get you started.
Cheers!!!
