What is ROI (Return on Investment)?
Return on Investment (ROI) is a fundamental financial metric used to evaluate the efficiency and profitability of an investment. It measures the amount of return on an investment relative to the investment's cost, expressed as a percentage or ratio.
Basic ROI Formula
ROI = (Net Profit / Cost of Investment) × 100
Or alternatively:
ROI = ((Current Value - Initial Investment) / Initial Investment) × 100
How to Calculate ROI: Step-by-Step
- Identify Total Returns: Calculate all gains from the investment including profits, dividends, interest, or savings.
- Calculate Total Costs: Include initial investment plus any additional costs like fees, maintenance, or taxes.
- Find Net Profit: Subtract total costs from total returns.
- Apply the Formula: Divide net profit by initial investment and multiply by 100.
Simple ROI Calculation Example
Investment Scenario: You invest $10,000 in stocks and sell them for $12,500 after one year.
- Initial Investment: $10,000
- Final Value: $12,500
- Net Profit: $12,500 - $10,000 = $2,500
- ROI: ($2,500 ÷ $10,000) × 100 = 25%
Types of ROI Calculations
Simple ROI
The basic calculation that doesn't account for time value of money. Best for short-term investments or quick comparisons.
Annualized ROI
Adjusts ROI to show the equivalent annual return, useful for comparing investments held for different time periods.
Annualized ROI Formula
Annualized ROI = ((1 + ROI)^(1/n)) - 1
Where n = number of years
Risk-Adjusted ROI
Considers the risk level of investments using metrics like the Sharpe ratio or adjusting returns for volatility.
ROI in Different Investment Types
Stock Market Investments
| Investment Type | Typical Annual ROI | Risk Level |
|---|---|---|
| S&P 500 Index | 10-12% | Moderate |
| Individual Stocks | Variable | High |
| Bonds | 3-6% | Low |
| REITs | 8-12% | Moderate |
Real Estate ROI
Real estate ROI includes both cash flow and appreciation:
- Cash-on-Cash Return: Annual cash flow divided by cash invested
- Cap Rate: Net operating income divided by property value
- Total Return: Includes rental income plus property appreciation
Business Investment ROI
For business investments, ROI calculations may include:
- Marketing campaign ROI
- Equipment purchase ROI
- Employee training ROI
- Technology implementation ROI
Advanced ROI Calculations
Net Present Value (NPV)
NPV accounts for the time value of money by discounting future cash flows back to present value:
NPV Formula
NPV = Σ(Cash Flow / (1 + r)^t) - Initial Investment
Where r = discount rate, t = time period
Internal Rate of Return (IRR)
IRR is the discount rate that makes NPV equal to zero. It represents the actual annual return of the investment.
Modified ROI Metrics
- ROIC (Return on Invested Capital): Measures return on all capital invested
- ROAS (Return on Advertising Spend): Specific to marketing investments
- ROE (Return on Equity): Measures return relative to shareholder equity
ROI Benchmarks and Targets
General ROI Benchmarks
| ROI Range | Assessment | Action |
