calculatation the % difference

[Anonymous]

I create a table like this in Power Bi. How would I calculate the % difference from this table  similar to the example? The information is found in four diff tables in the Power Bi model. 

For example: 

% Difference: (V1-V2)/[(V1+V2)/2]*100

1. (53-63)/[(53+63)/2]*100=10%

2. (63-53)/[63+53)/2]*100=17.24%

=(53-63)/((53+63)/2)*100 =-17.24

@Anonymous , your math in your example doesn't work. What are you doing with the brackets?

It would be -14%. I'm trying to create a formula that would calculation the % difference within the Power Bi.
