CAGR HELP! Forecasting using Current data

[7ballp25]

I literally forgot how to do this, please help. 

I have a table that has 2018-2022 Year sales.

I created a whatifparameter from 0-100% to be the CAGR value. Focusing only on 2022 sales, I want the user to be able to select their desired CAGR % and see what the how it impacts 2023-2025 forecasted sales.

Forecasted Sales is dax table using Union Row...example below

Hi @7ballp25 
Here is a sample file with the solution https://we.tl/t-UvJsRpmiYd

Forcasted Sales = 
VAR LastAvialableYear = 
    MAX ( Data[Year] ) 
VAR LastAvailableSales = 
    CALCULATE ( SUM ( Data[Sales] ),'Data'[Year] = LastAvialableYear )
VAR CurrentYear = 
    MAX ('New Data'[Year] )
VAR YearDifference =
    CurrentYear - LastAvialableYear
VAR SelectedPercent =
    SELECTEDVALUE ( Parameter[Selected %] )
RETURN
    LastAvailableSales * POWER ( 1 + SelectedPercent, YearDifference )
