Definition of Return on Investment (ROI)

Return on investment (ROI) is a financial metric used to measure the profitability of an investment relative to its cost. It is expressed as a percentage and helps investors and businesses assess the efficiency of an investment. A higher ROI indicates better returns, while a lower ROI suggests lower profitability.

For example, if an investor buys a property for $200,000 and later sells it for $250,000, the ROI measures the percentage gain on the initial investment.

Purpose of ROI in Finance and Business

ROI is widely used for:

• Evaluating the profitability of investments in stocks, real estate, or business ventures.
• Comparing different investment opportunities to maximize returns.
• Measuring business performance by analyzing returns on marketing, projects, and capital expenditures.
• Assisting in strategic decision-making for long-term financial planning.
• Determining the effectiveness of cost-saving initiatives in companies.

How to Calculate ROI

ROI Formula

ROI = (Net Profit / Initial Investment) × 100

Example Calculation

• An investor spends $50,000 on stocks and later sells them for $65,000.
• Net Profit = $65,000 - $50,000 = $15,000.
• ROI = ($15,000 / $50,000) × 100 = 30%.

This means the investment generated a 30% return on the initial capital.

Types of ROI

Business ROI

• Measures the profitability of company initiatives, such as marketing campaigns or product launches.
• Example: A business invests $10,000 in digital marketing and earns $20,000 in additional sales, resulting in a 100% ROI.

Investment ROI

• Assesses the return on stocks, bonds, or real estate investments.
• Example: A mutual fund provides a 12% ROI over one year.

Social ROI (SROI)

• Used in non-profits and social enterprises to measure the impact of investments in social programs.
• Example: A community development project improves education access, generating social value beyond financial gains.

Marketing ROI

• Evaluates the effectiveness of advertising and marketing efforts.
• Example: A company spends $5,000 on an ad campaign and gains $15,000 in revenue, yielding a 200% ROI.
