Frequently asked questions
How is ROI calculated?
ROI equals (final value minus cost) divided by cost, times 100. A cost of 30,000 that returns 45,000 gives a 15,000 profit and an ROI of 50 percent. A negative result means the investment lost money.
What is a good ROI?
It depends entirely on the asset class, the risk taken and the holding period. Stock market index returns have historically averaged high single digits per year in nominal terms, while business or marketing investments are often judged against a higher hurdle.
