cumulative sum

Hello I would like to obtain this result

I want to make a cumulative sum each in relation to my previous value, my base value is that of B

indexAB
11015
220=15+20=35
330=35+30=65
440=65+40=105


Result:

IndexAB
11015
22035
33065
440105

earlier doesn't work
B =
IF (
    test[Index] = 1
    test[B]
    CALCULATE(
        SUMX(
            FILTER(
                test,
               test[Index] <= EARLIER(test[Index])  
            ),
            test[B]  
        )
    )
)
thank you for your feedback

Hi @Lebron45 ,


powerbidev123's reply could return the result you want. However if A1 is not 10, it will not work. I don't suggest you to use EARLIER() function, it may cause bad performance if you have large size of data.

You can also try my code to create a calculated column.

B =
VAR _B1 = 15
VAR _CurrentIndex = 'Table'[index]
RETURN
    IF (
        'Table'[index] = 1,
        _B1,
        _B1
            + CALCULATE (
                SUM ( 'Table'[A] ),
                FILTER ( 'Table', 'Table'[index] > 1 && 'Table'[index] <= _CurrentIndex )
            )
    )

Result is as below.

Hi @Lebron45 , Let me know if this helps

B =
5 + SUMX(
    FILTER(
        'Table (3)',
        'Table (3)'[Index] <= EARLIER('Table (3)'[Index])
    ),
    'Table (3)'[A]
)

@Lebron45 , Try using 

Cumulative B =
CALCULATE(
SUM(test[A]),
FILTER(
ALL(test),
test[Index] <= MAX(test[Index])
)
) + MIN(test[B])

@bhanu_gautam I already tried, but it doesn't work, "earlier" shows me an error

hi @bhanu_gautam thank you for your feedback, but I would like to fill my column B from the second and each time by making my value from the current line of my column A + my last value from the previous line of column B
