Return on Investment (ROI) is a key financial metric that measures the profitability of an investment relative to its cost. It is calculated as: ROI = (Net Profit / Investment) × 100%, where Net Profit = Total Return − Total Investment. ROI is expressed as a percentage and can be positive (profit) or negative (loss). The annualized ROI accounts for the holding period, allowing comparison of investments with different time horizons. This calculator helps investors, business owners, and financial analysts evaluate investment performance, compare different opportunities, and make informed decisions. Understanding ROI is essential for capital allocation, project evaluation, and portfolio management.
