Average Cost Stock Calculator
Investing in the stock market often involves purchasing shares at different prices over time. As you continue buying additional shares, it becomes difficult to manually determine the average price you paid for each share. This is where an Average Cost Stock Calculator becomes an essential tool for every investor.
Whether you’re a beginner or an experienced trader, understanding your average purchase price helps you evaluate your portfolio accurately. It allows you to know whether your current investment is in profit or loss and helps you make informed buying or selling decisions.
Instead of performing lengthy calculations with a spreadsheet, an Average Cost Stock Calculator instantly calculates the weighted average cost of your holdings. Simply enter the number of shares purchased and their respective prices, and the calculator provides an accurate average cost per share within seconds.
This calculator is especially useful for investors who use strategies such as dollar-cost averaging, where shares are purchased periodically at different prices. By knowing your true average cost, you can better manage risk, set realistic profit targets, and improve long-term investment planning.
Whether you invest in individual stocks, ETFs, or mutual funds, using an Average Cost Stock Calculator saves time, minimizes mistakes, and provides valuable insights into your investment performance.

Example
Suppose you purchased:
- 100 shares at $20
- 50 shares at $30
- 150 shares at $25
Total Investment:
(100 × 20) + (50 × 30) + (150 × 25)
= $2,000 + $1,500 + $3,750
= $7,250
Total Shares:
100 + 50 + 150 = 300 shares
Average Cost:
$7,250 ÷ 300 = $24.17 per share
