Annual average between period of years

[gustavofarias10]

I have filtered a certain range of years that present the following data:

year 2015 = 72
year 2016 = 77
year 2017 = 61
year 2018 = 97

I already have the following data:
variation in the period: 34.7%
variation in the last year: 6.5%

But I need to know how to arrive at the annual average, which in this case is equal to 10.4%.

Hi, @gustavofarias10 

You can try the following methods.

Measure % = 
Var _current=SUM('Table'[Value])
Var _Previous=CALCULATE(SUM('Table'[Value]),FILTER(ALL('Table'),[Year]=SELECTEDVALUE('Table'[Year])-1))
Return
DIVIDE(_current-_Previous,_current)

Average% = 
Var _table=SUMMARIZE('Table','Table'[Year],"%",[Measure %])
Return
DIVIDE(SUMX(FILTER(_table,[Year]>=MIN('Table'[Year])&&[Year]<=MAX('Table'[Year])),[%]),MAX('Table'[Year])-MIN('Table'[Year]))

Is this the result you expect? Please see the attached document.

Hi @gustavofarias10 

Here is a DAX Formula:

CAGR = 
VAR StartingYear = MIN('TableName'[YearColumn])
VAR EndingYear = MAX('TableName'[YearColumn])
VAR StartingValue = CALCULATE(SUM('TableName'[ValueColumn]), 'TableName'[YearColumn] = StartingYear)
VAR EndingValue = CALCULATE(SUM('TableName'[ValueColumn]), 'TableName'[YearColumn] = EndingYear)
VAR NumberOfYears = EndingYear - StartingYear
RETURN
IF(
    NumberOfYears > 0,
    POWER(EndingValue / StartingValue, 1 / NumberOfYears) - 1,
    BLANK()
)

Please replace with the correct table names, and it should work.
