Fixed cumulative sum (current month)

[Anonymous]

I need to calculate an accumulated sum and use the accumulated value for the current month as a variable to add the value column for the other previous months. Example:

Mês	Valor	Acumulado	Resultado
Janeiro	10	10	80+10=90
Fevereiro	10	20	80+20=100
Março	10	30	80+30=110
Abril	10	40	80+40=120
Maio	10	50	80+50=130
Junho	10	60	80+60=140
Julho	10	70	80+70=150
Agosto	10	80	80+80=160
Setembro	10	90	80+90=170
Outubro	10	100	80+100=180
Novembro	10	110	80+110=190

I created a measurement to return the value for the month of August, but when I put the measurement on the graph, I have the result below.

Mês	Valor	Acumulado	Resultado
Janeiro	10	10	10+10 =20
Fevereiro	10	20	10+20=30
Março	10	30	10+30=40
Abril	10	40	10+40=50
Maio	10	50	10+50=60
Junho	10	60	10+60=70
Julho	10	70	10+70=80
Agosto	10	80	10+80=90
Setembro	10	90	10+90=100
Outubro	10	100	10+100=110
Novembro	10	110	10+110=120

I need the accumulated value of the current month (August) to add with the value column for each month.
can you help me?

HI @Anonymous ,

Create an index column in Power Query

Then create these Calculated Columns

Ac = SUMX(FILTER('Table','Table'[Index] <= EARLIER('Table'[Index])),'Table'[Valor])

RE = 
var Augusto = SUMX(FILTER('Table','Table'[Mês] = "Agosto"),'Table'[Ac])
RETURN
Augusto + 'Table'[Ac]
