Calculating PV as a Measure

[redg]

This is my first post on literally any user group, so go easy on me 🙂

I am building a dashboard that calculates PV for a group of accounts.  I'm attempting to leverage What-If parameters to allow the user to interact with the rate for that calculation, and because of that I am left writing the following measure:

gross_funding_am = PV(((wavg_discount_rt[wavg_discount_rt Value] / 100) / 12), average(myTbl[term]), average((myTbl[payment])) * -1, sum(myTbl[expected_balloon]) * -1)

This seems to yield the correct results on a row level, but the aggregate level gets a bit wonky.  For context on the picture below, the resulting total should be higher than that of the acct_loan_am field: 

 I know other users have posted in the past for simpler issues and the answer was something using SUMX, but for something that (in my mind) is more complicated like a PV function, how would I fix this so that it totals properly?

Hi @redg ,

Please refer to the pbix file to see if it helps you.

Modify the measure.

gross_funding_am_sum =
VAR _b =
    SUMMARIZE ( 'Sheet1', Sheet1[account_id], "aaa", [gross_funding_am] )
RETURN
    IF ( ISINSCOPE ( Sheet1[account_id] ), [gross_funding_am], SUMX ( _b, [aaa] ) )

This was it @v-rongtiep-msft !!  Thanks so much 🙂

Hi @redg ,

Please have a try

Create a measure.

Measure =
VAR _a = [gross]
VAR _b =
    SUMMARIZE ( 'Table', 'Table'[Index.1], "aaa", _a )
RETURN
    IF ( HASONEVALUE ( 'Table'[Index.1] ), _a, SUMX ( _b, [aaa] ) )

The gross measure stands for gross_funding_am. You can use the id column replace index.1 column.

Hi @v-rongtiep-msft !

Thanks for taking the time to respond.  I'm not sure that i'm understanding your solution and associated image properly.  I think I'm not understanding something about your solution - I would expect the sum of the gross_funding_am field to be $17,883.33, not $23,452.20.  I've also tried to implement your idea and i'm getting a sum of $32,980.99 (which further entrenches my belief that I'm not understanding what you mean).  Can you elaborate a bit?

Thanks!

Hi @redg ,

It seems that the total value of measure is not correct, right? This document has a detailed explanation.

Please refer to.

hi @v-rongtiep-msft,

I'm attempting to share the PBIX file in a link here.  Forgive me if this goes sideways... first time.

Hi,

In the total row, do ou want to add the figure appearing int the table visual above?  Share the link from where i can download your PBI file.

Hi @Ashish_Mathur !

I would expect the total of the gross_funding_am column to equal 17,883.33 but that's not happening at the moment.  I'm not entirely sure how to upload my pbix file here but as soon as I do I will follow-up.

Hi @Ashish_Mathur 

I think I figured out the uploading.  Here is the link:
