Cumulative measure for count

[Anonymous]

I have table that looks as follows:

 

I have the month year and count. The cumulative is the measure that i would like to create. The value for jan 2018 is the same. Then Feb = count of Jan + Count of Feb. and March = count of Feb + Count of March and so on.

Any help? Thanks!

This should work for your example

Cumulative Count = 
CALCULATE(
    SUM( 'Cumu Count Ex'[Count]),
    FILTER(
        ALL('Cumu Count Ex'[Date]),
        MAX('Cumu Count Ex'[Date]) >= 'Cumu Count Ex'[Date] 
    )
)
