% Variance between 2 numbers
Comments

Assuming you want the
subtract X from Y to get an absolute value "V"
get the MAX of "X" and "Y" [to get the greater of the two]
"V"/(MAX of "X" & "Y") [format this column as percentage  don't forget to increase your decimal place accuracy]
=ABS([Column2]21  [Column3]21) / MAX([Column2]21:[Column3]21)

Ezra,
I did the calculation, but I get the value 1 instead of 100%, how can I increase the decimal place to show 100 in the formula?
Thanks for the help?

Just change the column or cell to a percentage format (next to currency format in the top toolbar)
.25 = 25%
.5 = 50%
1 = 100%

Worked Thanks

This is great; however, what if you needed to show the percentage of increase OR decrease?

we have the same question at Melody...

To see if it is an increase or decrease remove the abs( ) part of the equation. It is what makes everything positive.
=[Column2]21  [Column3]21) / MAX([Column2]21:[Column3]21
This will allow the positive and negative values to show.
