Input:

Date                       Value

Hi @Anonymous,

You can create a calculated column:

Column = CALCULATE(SUM('Table3'[Value]),FILTER('Table3','Table3'[Date]<=EARLIER('Table3'[Date])))

How do we calculate the prior row value and current row value? For example the Final Value being 3, 6, 5, 13

Date                       Value      Final Value
22march 2017             3               3

23march 2017             3               6

24march 2017             2               5

25march 2017             11            13

01 January 2018           5             16

Hi,

Try this calculated column formula

=[Value]+lookupvalue(data[value],data[date],calculate(max(data[date]),filter(data,data[date]<earlier(data[date]))))

Hope this helps.

Hi,

Is it possible to do this for each week? I mean summing the values per week.

Thanks.

@v-qiuyu-msft thanks for the solution, it was exactly what I was looking for. I just have another question. Is it possible to perform the same calculation using a measure? If not, not a problem.

Of course. You can create a measure below:

Measure=CALCULATE(SUM('Table3'[Value]),FILTER(all('Table3'),'Table3'[Date]<=Max('Table3'[Date])))

your formulas really helped me a lot. Now I have the question if the same calculation can be made in Power Query (Custom column)?

Link to image . Cuz I want to use my calculated columns in Data pane (Link to image ) as an import into new Power Queries.

Thanks a lot in advance.

Best regards
