When you buy the same stock multiple times at different prices, it becomes difficult to manually calculate your average purchase price. This gives you a purchase-price average before fees, taxes, sales and corporate actions.
A Stock Average Calculator simplifies this entire process by instantly computing your weighted-average purchase price based on all your buy entries.
Calculate your average share price
Enter purchases of one stock. Price is in rupees; quantity is a positive whole number of shares. Remove any unused row. You can add up to 100 purchases.
This calculation excludes brokerage, fees, taxes, sales and corporate actions. It is an arithmetic purchase-price average, not a tax cost-basis calculation or a recommendation to buy or sell.
What Is a Stock Average Calculator?
A Stock Average Calculator is an online tool that helps investors determine the average cost per share when they buy a stock in multiple instalments (at different prices and quantities).
This is especially useful when:
- You average up or average down
- You invest systematically over time
- You want to know break-even levels before selling
The calculator applies the weighted-average formula to the purchase entries you provide.
Why Is Average Price Important?
Your average price helps you:
- Understand your average purchase price
- Plan exit strategies more confidently
- Compare your purchase price with a sale price
- Decide whether further averaging makes sense
For active traders and long-term investors alike, it’s one of the most important metrics for portfolio tracking.
How to Calculate Average Share Price
To compute your average, you multiply each purchase price by the number of shares bought, add all these values, and then divide by the total number of shares.
Formula
Average share price = total purchase value ÷ total shares. Total purchase value is the sum of each purchase price multiplied by its quantity.
Where:
- P = Price of each purchase
- Q = Quantity of shares purchased
- n = Number of purchase transactions
Example
Suppose you bought:
- 100 shares at ₹250
- 200 shares at ₹275
Total purchase value = (100 × ₹250) + (200 × ₹275) = ₹80,000. Total shares = 100 + 200 = 300.
Average share price = ₹80,000 ÷ 300 = ₹266.67, rounded to two decimal places.
