Cumulative sum of a measure

[Oomsen]

This is my measure Cashflow forecast = CALCULATE(SUM(Beginbalans[Periode beginsaldo]) + [Liquide middelen] + SUM('Debiteuren'[Bedrag]) + SUM('Crediteuren'[Bedrag])) I would like to have the cumulative per month.

Why are you using Calculate in this case? You aren't applying any filter context. 

Regarding your question. Add this measure to a column chart with the months on your x-axis... This should work, in case this results in the same value for every month, check your relationships in your model and your DAX measures. Your referencing other measures like [Liquide midellen] which might impact the filter context of your measure.

I thougt Calculate wass neccesary. Now i see it doesn't. But the result of sum is the amount per month and not the cumulative per month. this is my result:

                Openingbalans      Cashchanges      Receivables     Payables   Cashflow

Jan           362441,14              -94613,17           0                     0                267827,97

Feb           0                            -271768,02         0                     0                -271768,02

What i want to see is 267827,97 - 271768.,02 = -3940,05

Ah... there is your problem. What you're trying to do is calculated a running total. 
Now in your example, there is a row context. So for every row you're doint the calculation. What you should do, is create the a total till the current rowcontext. 

A running total is explained here at the DAX patterns site. 

Query should look like this: 

MeasureName = 
CALCULATE (
    [YourMeasure];
    FILTER (
        ALL ( datetable[date] );
       datetable[date] <= MAX ( datetable[date] )
    )
)

I've also created an example file for you which you can download here. 

Hope this works for you.
