Running Total for values calculated by measure

hI PHanus3 

To sum the cumulative values of [Total] for each year, you could use a measure like this (change table/column names as needed):

Running Total = 
CALCULATE (
    SUMX (
        VALUES ( YearOfProject[Year of Project] ),
        [Total]
    ),
    YearOfProject[Year of Project]
        <= MAX ( YearOfProject[Year of Project] )
)

In your particular example, since the underlying measures form a geometric sequence, you could also consider using the formula for the sum of a geometric sequence which would avoid iteration.
