Calculate your Return on Investment (ROI) and analyze investment performance

What is ROI?

ROI (Return on Investment) is a key financial metric used to evaluate the profitability or efficiency of an investment. It measures the return generated relative to the cost of the investment and is expressed as a percentage. ROI is widely used in personal finance, business decisions, and investment analysis because it provides a straightforward way to assess and compare different opportunities.

Formula for ROI

ROI = (Net Profit / Cost of Investment) × 100

Where:

  • Net Profit = Total returns or gains − Investment cost
  • Cost of Investment = The total amount spent on the investment

Example of ROI Calculation

If you invest $1,000 in a project and earn $1,200 in return, the net profit is $200 ($1,200 − $1,000). Using the ROI formula:

ROI = ($200 / $1,000) × 100 = 20%

Why ROI is Important

  • Simplicity: ROI is easy to calculate and understand, making it accessible for both beginners and professionals.

Limitations of ROI

While ROI is an essential tool, it does have limitations:

  • Timeframe Ignored: ROI does not account for how long it takes to achieve the return. For instance, two investments with the same ROI could have vastly different durations, which affects their value.
  • External Factors: It doesn't factor in inflation, market volatility, or risk, which are critical for a more comprehensive investment evaluation.
