Basic ROI Formula
ROI (%) = [(Amount Returned - Amount Invested) / Amount Invested] × 100
Example: If you invested $1,000 and received $1,200, your ROI = [($1,200 - $1,000) / $1,000] × 100 = 20%
Investment Gain Formula
Investment Gain = Amount Returned - Amount Invested
Example: $1,200 - $1,000 = $200 gain
Annualized ROI Formula
Annualized ROI (%) = [(Amount Returned / Amount Invested)^(1/Years)] - 1] × 100
Example: For a 20% return over 2 years: [(1.20)^(1/2) - 1] × 100 = 9.54% per year
