    If you are creating a

    ABC = 
DIVIDE(AVG2[col1]+AVG2[col2]+AVG2[col3]+AVG2[col4]+AVG2[col5],

IF(ISBLANK(AVG2[col1]),0,1)+
IF(ISBLANK(AVG2[col2]),0,1)+

IF(ISBLANK(AVG2[col3]),0,1)+
IF(ISBLANK(AVG2[col4]),0,1)+

IF(ISBLANK(AVG2[col5]),0,1)
,BLANK())

    calculated column then you may need to use this.

The average function skips the Blank/NULL values from data. i.e. if the Price is null for the period then that period will not be calculated on Average. And when you are writing the DAX formula in Power BI you are explicitly dividing it by 9 hence giving you an average of by 9.

    FarhanAhmed  Thank you!

    Can I also know how to correct the formula so as to get the same result as excel?

      In Divisor you need to put something like 

       

      = VALUES / ( COUNT(column1) + COUNT(Column2) + COUNT(column3) .... COUNT(Column9))

       

      this count will give nothing when it finds null values. so it will divide your data by 5 instead of 9. if all columns have some value then it will divide by 9

        Hi FarhanAhmed ,

        Thank you!

        When I apply that formula I get 0%.

        I have attached the image below:
