Calculate ROI by dividing the investment gain by the initial investment cost, then multiplying by 100 to get a percentage: ROI = (Gain - Cost) / Cost × 100.
Return on Investment (ROI) is a fundamental metric that measures the efficiency and profitability of an investment. The basic formula is: ROI = (Investment Gain - Investment Cost) / Investment Cost × 100.
For example, if you invest $10,000 in stocks and sell them for $12,000, your ROI is: ($12,000 - $10,000) / $10,000 × 100 = 20%.
For investments generating periodic income (like dividends or rent), include total returns: ROI = (Ending Value - Beginning Value + Income) / Beginning Value × 100. If that $10,000 stock investment is now worth $11,500 and paid $500 in dividends, ROI = ($11,500 - $10,000 + $500) / $10,000 × 100 = 20%.
For annualized ROI over multiple years, use: Annualized ROI = [(Ending Value / Beginning Value)^(1/years)] - 1.
Consider additional costs like transaction fees, taxes, and management fees in your calculations for accurate results. For real estate, include closing costs, maintenance, and property taxes.
ROI is useful for comparing different investments, but consider risk levels and time horizons. A 20% ROI over one year differs significantly from 20% over five years.
