wrong sum of expense when selecting multiple date

[eliasayy]

Hello everyone,

PBIX file : https://1drv.ms/u/s!Ag9tIyk2ofNRjlBFygNBL3s9VG2N?e=qoIeBc
Excel file: https://1drv.ms/x/s!Ag9tIyk2ofNRjk9-uND6F2ZLZgaZ?e=oAWQzt

I have revenue table which includes service name and all, and expense table which include service expense

to calculate percentage, i need to do servicerevnue / total_revenue
then service expense is calculated_percentage * total-service_expense

when i select for example october 4:

and when i select october 5:

and when i select both:

 

as you see, lets take service A:

on october 4, expense is 163.58 and gross is 1,041.42

on october 5, expense is 32.63 and gross is 376.47
so if i select october 4 and october 5 together:
i should get for expense = 196.21 and gross = 1417.99

but as photo above states, i got the numbers wrong

please help

Hi @eliasayy 
Please refer to attached sample file with the solution

Taxes = 
SUMX ( 
    VALUES ( 'Calendar'[Date] ),
    CALCULATE ( 
        SUM ( Expense_Table[Total] ) * MAX  ( New_Tax_Rate_Table[Percentage] )
    )
)

@tamerj1 why is it when i do the calculations seperatly it works but when i make them into one measure and use Var it doesnt give the same answer?

@eliasayy 
Please provide more context. Please provide one example.

@tamerj1  i already provided example and the powerbi file in the main topic

@tamerj1 thank you very much i appreciate your help

for somereason it works on the sample data but i did the same exact calculation and method on my work project but doesnt work for some reason

@eliasayy 
Perhaps it has a different filter context. Maybe you can share more details to assist you further.

Thank you veey much but this is another post for taxes and this one is for the expense can you please help out

[tamerj1]

@eliasayy 

Sure. However, it is the same approach; you need to iterate over the the selected dates one by one, perform the calculation for each date then sum the individual results for all the selected dates. 
what is the formula for Expanses?

[eliasayy]

@tamerj1 it is included in the powerbi file but this is the formula

ServicerevenueA = CALCULATE(SUM(revenue_table[total]),revenu_table[service]= "Service A")

Total revenue = SUM(revenue_table[total])

PercentageA = [servicerevenueA]/[total revenue]

Service expense = CALCULATE(SUM(expense_table[total]),expense_table[eligible for service revenue] = "true")

ExpenseA = [PercentageA] * [serviceexpense]
