column sum incorrect

Hi, NadiaHap 

According to your description, the Total in the [% budget/ discount 3/discount 1] measure is not you need. You need to get the sum of the value . Right?

Here are the steps you can refer to :
(1)This is my test data:

The [% budget/ discount 3/discount 1] measure in my side is look like this:

% budget/ discount 3/discount 1 = var _dis3 = MAX('Table'[discount 3])
var _dis1 = MAX('Table'[discount 1])
return
[% budget]/(_dis3+1)/(_dis1+1)

(2)Then we can create another measure based on this measure:

% budget/ discount 3/discount 1 End result = var _t =SUMMARIZE(ALLSELECTED('Table'),[Month],"% budget/ discount 3/discount 1",[% budget/ discount 3/discount 1])
return
IF(HASONEVALUE('Table'[Month]) , [% budget/ discount 3/discount 1] , SUMX(_t,[% budget/ discount 3/discount 1]))

(3)Then we put this measure on the viusal , we can get the Total you want in the end:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,
