What is Return on Investment?

Return on investment is simply the measurement, often represented in a percentage, of how much money you get back compared to what you put in. If I invested $1,000 last week in the stock market, and this week that money is $1,100, my return on investment would be 10%. It calculated as ((NEW - OLD) / OLD) 100 or ((1100-1000)/1000)100 = 10%.
