What Is a Stock Average Calculator?
When you buy shares of a company at different prices, your average purchase price changes with each transaction. A Stock Average Calculator helps you calculate the average price of your shares based on the quantity and price of each purchase.
For example, if you purchase a stock at ₹120 and buy more shares of the same stock at ₹150, the calculator helps you determine your average buying price across both transactions.
Whether you are making your first investment or adding more shares to your existing holdings, the Stock Average Calculator helps you understand your average acquisition cost and plan your investments more effectively.
How to Use the Stock Average Calculator?
Follow these simple steps to calculate the average price of your shares:
- Enter the purchase price of your first transaction.
- Enter the quantity of shares purchased at that price.
- Add the purchase price and quantity for each subsequent transaction.
- Click on the Calculate Average button.
- View your average purchase price and total quantity of shares.
You can add multiple purchase transactions to calculate the weighted average price of your stock holdings.
Stock Average Calculator Formula
The average purchase price of a stock is calculated by dividing the total amount invested across all purchases by the total number of shares purchased.
Formula:
Average Stock Price = Total Purchase Value ÷ Total Quantity of Shares
For multiple purchases:
Average Stock Price = [(Price₁ × Quantity₁) + (Price₂ × Quantity₂) + … + (Priceₙ × Quantityₙ)] ÷ (Quantity₁ + Quantity₂ + … + Quantityₙ)
Where:
- Price: Purchase price per share for each transaction.
- Quantity: Number of shares purchased in each transaction.
- Total Purchase Value: Sum of the purchase price multiplied by the quantity for every transaction.
- Total Quantity: Total number of shares purchased across all transactions.
Example of a Stock Average Calculator
Suppose you purchase shares of a company in two transactions:
- First purchase: 100 shares at ₹250 per share.
- Second purchase: 200 shares at ₹275 per share.
Using the stock average formula:
Total Purchase Value = (100 × ₹250) + (200 × ₹275)
Total Purchase Value = ₹25,000 + ₹55,000 = ₹80,000
Total Quantity of Shares = 100 + 200 = 300 shares
Average Purchase Price = ₹80,000 ÷ 300
Your average purchase price is ₹266.67 per share.
This means that you purchased 300 shares at a weighted average price of approximately ₹266.67 per share, excluding brokerage, taxes and other transaction charges.
