Questions
How do I calculate ROI?
ROI = (final value − amount invested) ÷ amount invested × 100. If 10,000 grows to 14,000 the ROI is 40%.
What is annualised ROI?
It is the steady yearly growth rate that would turn the starting amount into the final value over the time held, also called CAGR. 40% over 3 years is about 11.9% a year, not 13.3%.
