What Is a Stock Average Calculator?

A stock average calculator is a simple tool that calculates the average price you have paid for a stock across multiple purchases. It is useful when you buy shares at different prices and want to know your overall average cost.

How to Use the Stock Average Calculator

  1. Choose a Currency: Select your preferred currency from the available options. The default currency is USD.
  2. Enter Buy Price: Add the price at which you purchased each share.
  3. Enter Quantity: Enter the number of shares bought at that price.
  4. Add More Shares: Click the Add More button if you have made additional purchases.
  5. Check the Result: Your total shares, total investment, and average share price will update automatically.

Stock Average Calculator Example

Suppose you bought shares of a company in three different purchases:

PurchaseBuy PriceQuantityTotal Amount
Share 1$10010$1,000
Share 2$9020$1,800
Share 3$8010$800
Total40$3,600

Your average buying price is:

Average Price = Total Investment ÷ Total Shares

$3,600 ÷ 40 = $90 per share

So, your average buying price is $90 per share.

How Is the Average Stock Price Calculated?

The calculator uses a weighted average formula:

\text{Average Share Price} = \frac{\text{Total Investment}}{\text{Total Shares}}

It first adds the amount spent on each purchase and then divides that amount by the total number of shares.
