Average Stock Price – Formula, Calculation, and Example

Investing in the stock market is a must for those who are interested in creating long-term wealth. Most investors contribute small amounts each month to build their investment portfolio. However, the market price constantly changes, which can confuse the investor about the actual buying price. The average stock price gives you an idea about a price point beyond which you attain profitability as a whole.

This article concentrates on the concept of average stock price, its formula, ways of calculating it, and factors to consider when calculating it.

What is the Average Stock Price?

The average stock price is the weighted price at which an investor has bought shares of a given company across multiple transactions. This considers the number of stocks purchased and the prices at which each transaction took place, giving an overall picture of the average cost per share.

If, for instance, someone buys a particular stock four times at different prices, the average stock price represents the price above which you become profitable, helping you make better investment decisions.

Why is Calculating Average Stock Price Important?

Average stock price is important for the following reasons:

• Investment Evaluation- The average stock price tells you whether the current market price of the stock is more or less than your buying price.

• Strategic planning- It helps investors identify future investment opportunities. For example, many investors look to reinvest in a particular stock at each 10% fall. 

• Tax implications- An accurate average stock price can help you calculate the taxes to be paid based on capital gains.

• Loss minimization- You can use the average stock price metric to exit an investment. For example, an investor can set a risk management rule to exit any investment that has generated a 10% loss.

Formula to Calculate Average Stock Price

The formula for calculating the average stock price is as follows:

Average Stock Price = ∑(Price Per Share×Number of Shares Bought) / ∑(Number of Shares)

In simpler terms: 

Average Stock Price = Total Amount/Total Quantity

Step-by-Step Calculation

The steps in calculating the average stock price are as follows:

• List Transactions: Mention the price and number of shares associated with each transaction in a specific stock.

• Multiply price and quantity: For each transaction, multiply the price per share by the number of shares bought to determine the investment done in a particular transaction. Repeat for each transaction.

• Calculate Total Investment: Add up the investment done in each transaction to calculate the total investment.

• Total shares: Add the number of shares bought in each transaction. 

• Divide: Use the formula to divide the total investment by the total number of shares to get an average stock price.

Example of Average Stock Price Calculation

Let’s illustrate how to calculate the average stock price with a practical example:

Scenario:

You purchased stocks of company A three times, and the details of three transactions are mentioned below:

• Transaction 1: 10 shares at ₹100 per share
• Transaction 2: 20 shares at ₹120 per share
• Transaction 3: 15 shares at ₹90 per share

Step 1: Calculate the Total Cost for Each Transaction

• Transaction 1: ₹100 × 10 = ₹1,000
• Transaction 2: ₹120 × 20 = ₹2,400
• Transaction 3: ₹90 × 15 = ₹1,350

Step 2: Add Up the Total Costs and Total Shares

• Total Amount= ₹1,000 + ₹2,400 + ₹1,350 = ₹4,750
• Total Quantity = 10 + 20 + 15 = 45

Step 3: Apply the Formula

•  Average Stock Price =  Total Amount/Total Quantity =  ₹4,750/45   ≈  ₹105.56

So, the average stock price is ₹105.56 per share.

Factors to Consider When Calculating Average Stock Price

There are several factors that need to be considered when calculating the average price of the stock. Some of these factors are:

• Stock Splits: The total number of shares increases after a stock split, and this must be considered when calculating the average stock price.

• Dividends: Reinvested dividends can lower the total investment amount, hence decreasing the average stock price.

• Partial Selling of Shares: If the investor sells some of the shares, the average stock price should be determined for only the remaining shares.
