Frequently Asked Questions
What is the ROI formula?
ROI equals net gain divided by initial cost, multiplied by 100. Net gain is the final value minus the initial investment.
What is a good ROI?
ROI benchmarks vary by asset class and industry. Stock market investments historically return 7 to 10 percent per year. Marketing ROI expectations vary widely by channel.
What is the difference between ROI and CAGR?
ROI measures total return over a period without accounting for time. CAGR annualises the return to allow fair comparison across investments of different durations.
