Rate calculation across multiple months

Hello all,


I am calculating Rate % = Sum(Table1(Amt))/Sum(Table2(Amt))


I am using a mesuare to calculate this Rate %. The formula is - Rate%= IFERROR([A]/[B], BLANK())

where [A] is a measure = Sum(Table1(Amt))

[B] is a measure = Sum(Table2(Amt))


Now this is giving the right result. But if I select multiple months using month slicer, then it will calculate rate as

 Rate %= Sum(Table1(Amt)) for Jan + Sum(Table1(Amt)) for Feb/ Sum(Table2(Amt)) for Jan + Sum(Table2(Amt)) for Feb


what I want is Rate 1= Sum(Table1(Amt)) for Jan / Sum(Table2(Amt)) for Jan

Rate 2= Sum(Table1(Amt)) for Feb / Sum(Table2(Amt)) for Feb


Final Rate %= (Rate 1 + Rate 2)/2


I am new to power bi and dax so apologies if the question sounds silly.


Thanks in advance

Re: Rate calculation across multiple months

Hi @Anonymous,

In your resource date, there are date column in Table1 and Table2? And if there is relationship between the table?

I try to reproduce your scenario using the following sample table.



I create measure like, create a month in Table1 and a slicer inluding Table1[month], it return expected result in screenshot below.

rate = SUM(Table1[Amt])/SUM(Table2[Amt])


Please let me know if you have any question. The attached file is my sample data.

Best Regards,

Hi @v-huizhn-msft,


There is no direct relationship between the two tables. The two tables are given relationship with a Date Table. The Date Table is also used in the slicer.

Hi @Anonymous,

I got it, do you try the solution, and it didn't work? Could you please post your .pbix for analysis?
