What Is ROI?

Return on Investment (ROI) is a financial metric used to evaluate the efficiency and profitability of an investment. It measures how much gain or loss an investment has generated relative to its initial cost, expressed as a percentage.

ROI is one of the most widely used metrics in business and personal finance because it provides a simple, universal way to compare different investments. Whether you are evaluating stocks, real estate, a business project, or a marketing campaign, ROI gives you a clear picture of performance.

Formula & Methodology

Key formulas used in this calculator:

  • ROI % = ((Final Value − Initial Investment) / Initial Investment) × 100
  • Profit / Loss = Final Value − Initial Investment
  • Annualized ROI = ((Final Value / Initial Investment)1/years − 1) × 100
  • Monthly Return = ((Final Value / Initial Investment)1/months − 1) × 100

Practical Examples

Example 1: You invest $10,000 and after 3 years the investment is worth $15,000. ROI = 50%. Annualized ROI = 14.47%. Monthly return = 1.13%. Profit = $5,000.

Example 2: You invest $50,000 in a rental property and after 5 years it is worth $70,000. ROI = 40%. Annualized ROI = 6.96%. Profit = $20,000.
