There is a whole host of functions for statistical analyis functions.
The one that you wanted was growth.
=GROWTH(D1:D2,C1:C2,1991)-100
where d1:d2=100,200
c1:c2=1990,2000

Hope this helps

I could not find any Excel function for a very basic task: Calculating

Example: if in 1990 Ed weighed 100 and in 2000 Ed weighed 200, this
means that his weight rose by 7.18 percent in an average year between
1990 and 2000, as I can tell from using the compound interest
