# How to Calculate Weighted Average Price Per Share

by Matt McGew

Investors commonly purchase stocks at different price points. The weighted average price per share is a calculation that shows the average price of a specific stock held within a portfolio that the investor purchased at different price points. This calculation also takes into account varied quantities purchased in addition to the varied price points.

Determine the total number of a specific stock held in a portfolio. For example, assume you own 100 shares in a company's stock.

Multiply the price points that you purchased the stock at by the number of shares purchased, and add the sums. For example, assume you purchased 25 shares of a stock at \$15 per share, 50 shares of the same stock at \$20 per share, and another 25 shares at \$30 per share. (\$15 x 25) + (\$20 x 50) + (\$30 x 25) = \$375 + \$1,000 + 750 = \$2,125

Divide the sum of the individual price points by the total number of shares purchased. Continuing the example from Step 2, \$2,125 / 100 = \$21.25. This figure represents the weighted average price per share.
