Calculate forecast for a month based on average of completed days in the month

[mav_82]

Hi,

I need to show a line which has the actual sales by date which have passed in the month and then a dotted line which shows the average sales in the current month * the day of the month. So for example:

Date	Sale
01/09/2021	100
02/09/2021	200

The above are the actual sales, the average will be 150. for future dates i want to create a plot using dotted lines to show something like

Date	Forecast
03/09/2021	450 (150*3)
04/09/2021	600 (150*4)

and so on. Any help will be appreciated

Hello there! You can take advantage of the forecasting tools in Power BI, available in the Analytics pane, found in the Visualizations area of Power BI Desktop. The Analytics pane allows you to add dynamic reference lines to your visuals to provide focus for important trends or insights. 

You can create a measure using the AVERAGE() function and use it to plot a line chart and then use the forecasting tool as you please. 

Hope this answer solves your problem! If you need any additional help please tag me in your reply.
