I need a formula to calculate growth rate. eg. If I had 100 employees last year and I now have 150 employees this year the growth rate is 50 percent. But if I apply the same formula to 1260 last year and now have 2448 it doesn't work. The answer should come out to 94 percent growth rate. This is for an exam coming up shortly. If you think this is cheating please don't answer, but if you do answer at least I will have some idea about working out these formulae. The formula I used only seems to work with 10s, 100s or 1000s but not with anything else. Thank you.
