Do you simply mean an average of cells which are already %s?

=AVERAGE(A1:A10)

A1:A10 contains % values

That may or may not be a good procedure. It depends on the bases of
the percents.

For instance, if you have 10/100 = 10% and 2/10 = 20%, the average is
not 15%. Instead, you must compute (10+2)/(100+10) which is 10.91%.
