How ROI is Calculated

Understanding the formulas

Simple ROI Formula:

ROI = ((Final Value - Initial Investment) / Initial Investment) × 100

ROI = (($15,000 - $10,000) / $10,000) × 100 = 50.00%

Annualized ROI (CAGR) Formula:

CAGR = ((Final Value / Initial Investment)^(1/years) - 1) × 100

CAGR = (($15,000 / $10,000)^(1/3) - 1) × 100 = 14.47%

Strong Performance

14.5% annualized return beats the historical S&P 500 average of ~10%. Excellent investment!

Compare Annualized Returns

Always compare investments using annualized ROI (CAGR), not total ROI. A 50% return over 10 years (~4% annual) is worse than 20% over 2 years (~10% annual).

Quick Answer

ROI (Return on Investment) measures the profitability of an investment as a percentage. The formula is: ROI = (Gain - Cost) / Cost × 100. For example, investing 1,000 and gaining 1,200 gives ROI = (1,200 - 1,000) / $1,000 × 100 = 20%. Calculate any investment ROI instantly at practicalwebtools.com.

Key Facts

  • ROI formula: (Gain - Cost) / Cost × 100%
  • ROI expresses return as a percentage for easy comparison
  • Annualized ROI adjusts for different time periods
  • ROI does not account for risk - higher ROI often means higher risk
  • A 100% ROI means you doubled your money
  • Negative ROI means you lost money on the investment
  • Compare ROI across investments of similar risk and time horizon

Frequently Asked Questions

ROI measures the profitability of an investment relative to its cost. It's calculated as (Net Profit / Investment Cost) × 100. A 50% ROI means you earned 50 cents for every dollar invested.

Profitability measure: (Net Profit / Cost) × 100. 50% ROI = 50 cents earned per $1 invested.

Annualized ROI (CAGR) shows the equivalent annual return rate, making it easier to compare investments of different lengths. A 3-year investment with 50% total ROI has an annualized ROI of about 14.5%.

Yearly equivalent return rate. 50% over 3 years ≈ 14.5% annualized.

A "good" ROI varies by investment type. Stock market historically returns 7-10% annually. Real estate: 8-12%. Savings accounts: 1-5%. High-risk investments may target 15%+. Always compare to similar investments and consider risk.

Varies by type. Stocks: 7-10%, Real estate: 8-12%. Compare to similar investments.

Profit is the absolute dollar amount gained. ROI is the percentage return relative to the investment. A $10,000 profit on a $100,000 investment (10% ROI) is different from $10,000 on a $50,000 investment (20% ROI).

Profit is dollars gained. ROI is percentage return. Same profit, different ROIs based on investment size.

ROI doesn't account for time (use annualized ROI), risk, opportunity cost, or external factors like inflation. It also doesn't consider cash flow timing or reinvestment. Use alongside other metrics for better decisions.

Ignores time, risk, inflation, cash flow timing. Use with other metrics.
