How to use the average stock price calculator?

To calculate the average share price of a stock on the stock price calculator, simply enter the share purchase price and the number of shares bought of each stock, which will then give you the average share price. You can add as many different share prices and amounts bought as you need. 

How does the stock average calculator work? 

The stock cost average calculator tool adds all your shares bought at different prices and quantities, dividing them by the total amount used to purchase the stocks. In the end, you get the average price of the stock. 

How to calculate the average stock price?

The average cost deals with the summation of arithmetic cost divided by the number of the quantity or the number of items given.

Average cost = Total cost of the units bought/Number of units

The average price is a classic example of a price range, calculated by dividing the total sum of the cost and dividing it by the number of shares bought. The average stock price brings the stock to a single value, which in the end can be either higher or lower than expected, e.g., the stock’s initial cost per share. 

For instance, if you bought five shares for $5 per share for the first time and ten shares for $6 per share the next time, the average share price is the total buy price divided by the total of shares bought. 

Example

To calculate the average stock price, first calculate the total cost spent on the shares: 5 shares * $5 per share = $25, and 10 shares * $6 per share = $60; with $25 + $60 = $85 (the total cost). Then, calculate the total amount of shares bought: 5 + 10 = 15 (total shares). After which, calculate the average stock price by dividing the total cost of the shares, which is $85, by the total amount of shares bought, which is 15: $85 / 15 = $5.67 per share.
