Year Over Year Calculation With IF statement

[chq]

I am trying to create a year over year formula that would provide the percent change, however we did not collect any data in 2020 so I need to exclude the 2020 data and have 2021 compared against 2019. This is the formula that I came up with but it seems I did something wrong...Any suggestions?

% Change= [LY]/CALCULATE([LT], DATEADD('Master Date'[Date],-1,YEAR), IF('Master Date'[Year]="2020), CALCULATE( [LT Season], DATEADD('Master Date'[Date], -2, YEAR)

Thanks!

Hi @chq,

Add two columns as:

2 Years After = DATEADD('Table 1'[Date],2,YEAR)

2Years After sales = LOOKUPVALUE('Table 1'[Sales],'Table 1'[Date],'Table 1'[2 Years After])

 Here is the output:
