What Is a Stock Average Calculator?

- Enter Buy Price: Add the price at which you purchased each share.

Stock Average Calculator Example
Suppose you bought shares of a company in three different purchases:
| Purchase | Buy Price | Quantity | Total Amount |
|---|---|---|---|
| Share 1 | $100 | 10 | $1,000 |
| Share 2 | $90 | 20 | $1,800 |
| Share 3 | $80 | 10 | $800 |
| Total | 40 | $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:
It first adds the amount spent on each purchase and then divides that amount by the total number of shares.
