Calculating Rate of Return on Investment (ROI)

What is ROI?

Return on Investment (ROI) is a financial metric used to evaluate the efficiency of an investment. It measures the return relative to the cost of the investment, expressed as a percentage. Understanding ROI can help investors make informed decisions about where to allocate resources.

ROI Formula

The formula to calculate ROI is:

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

Where:

• Net Profit is the total revenue generated from the investment minus the initial cost of the investment.
• Cost of Investment is the total amount invested.

Example 1: Stock Investment

Let’s say you invest in stocks:

• Cost of Investment: $1,000
• Selling Price after 1 Year: $1,200

Step 1: Calculate Net Profit
Net Profit = Selling Price - Cost of Investment
Net Profit = \(1,200 - \)1,000 = $200

Step 2: Calculate ROI
ROI = (Net Profit / Cost of Investment) × 100
ROI = (\(200 / \)1,000) × 100
ROI = 20%

This means that your investment in stocks yielded a 20% return over one year.

Example 2: Real Estate Investment

Now consider a real estate investment:

• Cost of Investment: $150,000
• Selling Price after 5 Years: $200,000

Step 1: Calculate Net Profit
Net Profit = Selling Price - Cost of Investment
Net Profit = \(200,000 - \)150,000 = $50,000

Step 2: Calculate ROI
ROI = (Net Profit / Cost of Investment) × 100
ROI = (\(50,000 / \)150,000) × 100
ROI = 33.33%

Your real estate investment has earned a 33.33% return over five years.

Example 3: Business Investment

Suppose you start a small business:

• Initial Investment: $20,000
• Total Revenue after 3 Years: $30,000
• Operating Expenses: $5,000

Step 1: Calculate Net Profit
Net Profit = Total Revenue - Initial Investment - Operating Expenses
Net Profit = \(30,000 - \)20,000 - \(5,000 = \)5,000

Step 2: Calculate ROI
ROI = (Net Profit / Cost of Investment) × 100
ROI = (\(5,000 / \)20,000) × 100
ROI = 25%

In this case, your business investment resulted in a 25% ROI over three years.

Conclusion

Calculating the Rate of Return on Investment (ROI) is essential for evaluating the success of various investments. By understanding how to apply the ROI formula, you can make more informed financial decisions. Whether you’re investing in stocks, real estate, or starting a business, knowing your ROI helps you gauge the effectiveness of your investments.
