Frequently Asked Questions
What is ROI?▾
ROI = (Final Value − Initial Investment) / Initial Investment × 100. It expresses the gain or loss as a percentage of the original investment.
What is annualised ROI?▾
Annualised ROI = (Final/Initial)^(1/years) − 1. It converts total ROI into a consistent yearly rate, accounting for compounding.
Is a higher ROI always better?▾
Not necessarily — ROI must be compared against risk, holding period and alternative investments. A 50% ROI over 10 years is much less impressive than 50% in 1 year.
