Understanding ROI (Return on Investment)

ROI is a popular profitability metric used to evaluate how well an investment has performed. Whether you are investing in the stock market, real estate, or a marketing campaign for your business, knowing your ROI helps you make informed financial decisions.

The ROI Formula

The basic ROI calculation is straightforward:

ROI = ((Final Value – Initial Cost) / Initial Cost) x 100

While the basic ROI gives you a snapshot of growth, the Annualized ROI is often more useful. It accounts for the time the money was invested, allowing you to compare a 5-year investment with a 1-year investment on equal terms.

Practical ROI Example

Scenario: You invest $5,000 in a digital marketing campaign. At the end of the month, that campaign generated $7,500 in new sales.

  • Initial Cost: $5,000
  • Gain: $2,500 ($7,500 – $5,000)
  • ROI: ($2,500 / $5,000) x 100 = 50%

Why Annualized ROI Matters

If you earn 20% on an investment over 10 years, that is significantly different from earning 20% in 6 months. Our calculator uses the Compound Annual Growth Rate (CAGR) formula to provide your annualized return, which is essential for long-term wealth planning.
