How do i find growthin precentage form?

Question

I am investing in stocks and i am trying to make a somewhat orginized paper with many details about the stock. I was wondering what i would have to do to find out how much a stock has grown (percentage wise) over a 52-week period. I will use GOOG as an example, 52 weeks ago it was at 400.25 and now it is at 567.5, how would I find out how much the stock has grown(percentage wise)? ex. it has grown 15% over the past year. that sort of form

Answer 1

If you are looking at the price one year ago versus the price today, use this:

percentage growth = (new price -old price)/old price

for example: (567.5-400.25)/400.25 = 42 percent
