Average Share Price Calculator

The motivation to implement this application is to get an idea of the new reflected average/selling price of the share before making an actual investment. And it also helps to avoid errors occurs while doing manual calculations.

Let's understand with the below given example;

Let's assume, currently you have 100 shares of Reliance at the rate of ₹ 1000 (purchase price of a share) in your demat account. So, below given are your current investment details:

Total Invested Capital: ₹ 100,000

Total Number of Shares (Quantity): 100

Price per Share (Purchase Price): ₹ 1000

Average/Selling price per share: ₹ 1000

Now assume, the current price of Reliance's stock is ₹ 800. And now again you are planning to buy 50 more shares of Reliance at the rate of ₹ 800. So, here are the new investment details:

Total Capital required: ₹ 40,000

Total Number of Shares (Quantity): 50

Price per Share (Purchase Price): ₹ 800

Average/Selling price per share for new investment: ₹ 800

Now here is the million dollar question:

What is the final average/selling price of all 150 shares?

Here are the steps you can follow:

1. Click Here to open the app
2. In Price per share input field, enter the purchase price of the existing shares. (as per above example we have ₹ 1000 is price per share).
