show number of months (duration) instead of calender months

Hi, i have a lot of projects that run over 1 or more years. And to make comparison in what period of a project duration costs are made, i want to have the period visible of a projects duration.

I searched lot of stuff on internet, and found some answers with datediff dax function, but couldnt solve it .

So lets say i have 2 projects. One starts in jan 2022 and ends in june 2023. Its now december 2022 so jan is month 1 of the project, and today is month 12 of the project duration.

2nd project starts in june 2022 and ends in feb 2023, so start date is month/period 1 , december is month 7 etc.

How do i get this information in my tables? Do i need to add a column in query editor with some dax? Or do i need to create a new measure? 

I already added a measure to determine the duration of a project in months with

"duration = (today() - projecttable[startdate]) / 30"

which work as it shows currently 14th month for project started in june 2021.

Hi @bvdm1980 ,


If the start date takes up a month and you want a measure, please try this:

duration =

thanks, i got this already except the fact that it still doesnt give me a bar chart with costs per project month

i get 1 bar, with 1 amount for total project. So somehow it doesn't give me each specific project month as a data field. 

So i would want, for every project i select, a bar chart showing the costs per period since start date of the selected project. 

This allows me to compare every n-th period of a project costwise. Which could (f.e.) show that most costs are made in the 4th till 6th month after a project started. 

Hope this is clearer 🙂

@bvdm1980 , your DAX is correct. Add it as a column in the front end. Something like this. Let me know if this ok
