I am having a problem showing the percentage change for when both values are 0. For example, if my figure for 2020 was 0, and my figure for 2021 was 0. I would want my % change visual to show 0% - as there has been no change. However it is showing -100%. This only affects figures where they are both 0, it works perfectly if both figures are 1 and it would show 0% change.
Below is my measure i'm using - could anyone advise as to why this could be happening?

Mathematically, the correct formula for calculating difference from previous year is:
(Cur Year - Prev Year)/Prev Year
Based on that, you should modify your formula:
% Vic Change =
VAR _Num =
CALCULATE (
DISTINCTCOUNT ( 'Fact Incident'[Victim ID] ),
FILTER ( 'Date', 'Date'[Fiscal Year] = MAX ( 'Date'[Fiscal Year] ) )
)
VAR _Den =
CALCULATE (
DISTINCTCOUNT ( 'Fact Incident'[Victim ID] ),
FILTER ( 'date', 'Date'[Fiscal Year] = MIN ( 'Date'[Fiscal Year] ) )
)
VAR _PercentChange = IFERROR((_Num-_Den)/_Den ,0)
RETURN
_PercerntChange
Note: You may want to assign appropriate variable names.

If it doesn't, then please share a sample data along with the expected results (preferably an excel file and not an image)

Hello @Anonymous
I believe you need to modify the formula:
% Vic Change =
VAR _Num =
CALCULATE (
DISTINCTCOUNT ( 'Fact Incident'[Victim ID] ),
FILTER ( 'Date', 'Date'[Fiscal Year] = MAX ( 'Date'[Fiscal Year] ) )
)
VAR _Den =
CALCULATE (
DISTINCTCOUNT ( 'Fact Incident'[Victim ID] ),
FILTER ( 'date', 'Date'[Fiscal Year] = MIN ( 'Date'[Fiscal Year] ) )
)
VAR _PercentChange = IFERROR(_Num/_Den - 1,0)
RETURN
_PercerntChange
Cheers!

Hi @vivran22 thanks for this. Unfortunately the end result is the same = -100%.

@Anonymous You can add third parameter (write there 1) in DIVIDE function (what function returns when there is dividing by zero).
Hi @Anonymous , how would this look inside my current measure please? Thanks
That has gave the same result as mine did @Anonymous = -100%
