What Is Investment Return?

A comprehensive guide to understanding the concept of investment return, including definitions, examples, types, and calculations.

Investment return refers to the gain or loss generated on an investment relative to the amount of money invested. It serves as a measure of the profitability and performance of an investment. Returns can be positive, indicating a gain, or negative, indicating a loss. The return on investment (ROI) is a key metric used by investors to evaluate the efficiency and profitability of their investment choices.

Types of Investment Return

Total Return

Total return includes both capital gains (or losses) and income received from the investment, such as dividends or interest. It provides a complete measure of the investment’s performance.

$$ \text{Total Return} = \frac{(Ending Value - Beginning Value) + Income}{Beginning Value} $$

Annualized Return

The annualized return is the geometric average amount of money earned by an investment each year over a given time period. It provides a standardized measure to compare the returns of investments held for different lengths of time.

$$ \text{Annualized Return} = \left( \frac{Ending Value}{Beginning Value} \right)^{\frac{1}{n}} - 1 $$

where \( n \) is the number of years the investment is held.

Nominal vs. Real Return

• Nominal Return: The return on an investment without adjusting for inflation.
• Real Return: The nominal return adjusted for inflation, providing a more accurate measure of purchasing power.

$$ \text{Real Return} = \frac{1 + \text{Nominal Return}}{1 + \text{Inflation Rate}} - 1 $$

Calculating Investment Return

Example Calculation

Suppose you invest $1,000 in a stock, and one year later, the stock is worth $1,200, and you received $50 in dividends.

• Capital Gain: $1,200 - $1,000 = $200
• Total Income: $200 (Capital Gain) + $50 (Dividends) = $250
• Total Return: \(\frac{250}{1000} = 0.25\) or 25%

Annualized Return Example

Assume the investment above was held for 3 years instead of 1.

$$ \text{Annualized Return} = \left( \frac{1200}{1000} \right)^{\frac{1}{3}} - 1 = 0.0632 \text{ or } 6.32\% $$
