Working out the %age increase / decrease year on year

jonclay — Fri, 25 Oct 2024 10:53:09 GMT

Hi everyone

I'm trying to work out the percentage increase or decrease based on year on year values within a table.

I'm using this DAX Measure to calculate the value of payments from each contact:

Paid (Nett) = CALCULATE(SUM(values[nett]), FILTER(values, values[status]="Paid"))

This is then shown in a Table:

I'd like to achieve a DAX Measure (preferably) that shows the increase / decrease between the various years e.g. that 1983/1984 is a 2000% increased on 1982/1983 and that 1984/1985 is a 99% decreasd on 1983/1984 etc.

Could anyone please tell me the best way to achieve this?

Many thanks
Jon

Hello jonclay ,

You can try below dax :

YOY Change =

VAR CurrentYear = VALUE(LEFT(T_Paid[Fiscal_Year], 4))

VAR Previous_Year = CurrentYear - 1

VAR PreviousYearValue =

CALCULATE(

SUM(T_Paid[Paid_Nett]),

FILTER(

T_Paid,

VALUE(LEFT(T_Paid[Fiscal_Year], 4)) = Previous_Year

)

RETURN

IF(

NOT(ISBLANK(PreviousYearValue)),

(T_Paid[Paid_Nett] - PreviousYearValue) / PreviousYearValue,

BLANK()

)

I hope this helps. Did I answer your query ? Mark this as solution if this has solved your issue.

Cheers

Hi there divyed

Many thanks for your reply.

The Fiscal Year field is a calculated column on the Fin_Yr table, so I can't seem to get your code to work. I'm using the following code to create the column:

Fiscal Year = IF(month('Fin_Yr'[Date])<9,year('Fin_Yr'[Date])-1&"/"&year('Fin_Yr'[Date]),year('Fin_Yr'[Date])&"/"&year('Fin_Yr'[Date])+1)

How could I amend your code to accommodate this?

Many thanks
Jon

Hi jonclay ,

Thanks divyed for the quick reply. I have some other thoughts to add:

(1) We can create measures.

rank = RANKX ( SUMMARIZE ( ALLSELECTED ( 'Fin_Yr' ), [Fiscal Year], "nett", [Paid (Nett)] ), [Fiscal Year], MAX ( 'Fin_Yr'[Fiscal Year] ) )

Change = var _rank=[rank]+1 var _pre= CALCULATE([Paid (Nett)],FILTER(ALLSELECTED('values'),[rank]=_rank)) var _current=[Paid (Nett)] RETURN DIVIDE(_current-_pre,_pre)

(2) Then the result is as follows.
