What is Expected Return?
Expected return is the anticipated value of the profit or loss an investment will generate. It’s an essential concept in finance and investing, giving you a glimpse into the potential future performance of your investments. Whether you’re an aspiring Warren Buffett or just trying to make your savings work a little harder, knowing how to calculate expected return is crucial.
Key Concepts
Before we jump into the calculator, let’s clarify some essential terms:
- Expected Return (ER): The weighted average of all possible returns from an investment, considering the probabilities of each outcome.
- Probability (P): The likelihood that a particular return will occur.
- Return (R): The gain or loss from an investment over a specified period.
- Risk: The uncertainty associated with the return on an investment.
The Expected Return Formula
The formula for expected return is straightforward:
[ ER = \sum (P_i \times R_i) ]
Where:
- ( ER ) is the expected return.
- ( P_i ) is the probability of the ( i )-th return.
- ( R_i ) is the ( i )-th return.
In plain English: Multiply each possible return by its probability, then sum them all up.

FAQs
What is Expected Return?
Expected return is the anticipated average return on an investment, taking into account all possible outcomes and their probabilities.
How is Expected Return Calculated?
Expected return is calculated by multiplying each possible return by its probability and summing these products.
Why is Expected Return Important?
Expected return helps investors understand the potential profitability and risk of an investment, allowing for more informed decision-making.
Can Expected Return be Negative?
Yes, if the weighted average of all possible returns results in a negative value, the expected return can be negative, indicating a potential loss.
How Often Should I Calculate Expected Return?
It’s a good practice to calculate expected return periodically, especially when there are significant changes in market conditions or your investment portfolio.
Practical Examples
Let’s put theory into practice with a couple of examples.
Example 1: Single Investment
Imagine you have a stock with the following possible returns and probabilities:
- Return of 10% with a probability of 0.4
- Return of 5% with a probability of 0.3
- Return of -2% with a probability of 0.3
Using the formula:
[ ER = (0.4 \times 10\%) + (0.3 \times 5\%) + (0.3 \times -2\%) ]
[ ER = 4\% + 1.5\% – 0.6\% ]
[ ER = 4.9\% ]
So, the expected return is 4.9%.
Example 2: Multiple Investments
Suppose you’re evaluating a portfolio with two stocks:
- Stock A: 8% return with a probability of 0.6, 2% return with a probability of 0.4
- Stock B: 12% return with a probability of 0.5, -4% return with a probability of 0.5
For Stock A:
[ ER_A = (0.6 \times 8\%) + (0.4 \times 2\%) ]
[ ER_A = 4.8\% + 0.8\% ]
[ ER_A = 5.6\% ]
For Stock B:
[ ER_B = (0.5 \times 12\%) + (0.5 \times -4\%) ]
[ ER_B = 6\% – 2\% ]
[ ER_B = 4\% ]
Combine these to get the portfolio’s expected return, depending on the investment proportion.
