Backend Formula for the Stock Purchase Average Calculator
The Stock Purchase Average Calculator uses the formula: Total Cost of Shares / Total Number of Shares. This formula is straightforward but crucial for determining your average purchase price.
Step-by-Step Breakdown:
- Total Cost of Shares: This is calculated by multiplying the number of shares by the purchase price of each share. For example, if you bought 50 shares at $20 each, the total cost is $1,000.
- Total Number of Shares: This is simply the sum total of shares purchased.
- Average Purchase Price: Divide the total cost by the total number of shares. In our example, $1,000 divided by 50 shares equals an average purchase price of $20.
Common variations of this formula might include factoring in transaction fees or taxes, but the core calculation remains unchanged.
Step-by-Step Calculation Guide for the Stock Purchase Average Calculator
To manually calculate your average stock purchase price, follow these steps:
User-Friendly Breakdown: Begin by noting the total cost of all your stock purchases. Next, sum up the total number of shares acquired. Finally, divide the total cost by the number of shares to find your average purchase price.
Example 1: If you purchased 200 shares at $15 each and then another 300 shares at $10 each, the total cost is (200 * $15) + (300 * $10) = $3,000 + $3,000 = $6,000. The total number of shares is 500. Therefore, the average purchase price is $6,000 / 500 = $12.
Example 2: Suppose you bought 100 shares at $25, then 50 shares at $30. The total cost is (100 * $25) + (50 * $30) = $2,500 + $1,500 = $4,000. The total number of shares is 150, resulting in an average price of $4,000 / 150 = roughly $26.67.
Avoid common mistakes like forgetting to include all purchase transactions or miscalculating the total cost and shares.

Stock Purchase Average Case Study Example
Meet Sarah, a tech-savvy investor aiming to optimize her stock portfolio. Sarah recently started dollar-cost averaging into a technology stock.
Character Background: Sarah, a young professional, invests monthly into her chosen stock, hoping to lower her average purchase price over time.
Multiple Decision Points: Sarah uses the Stock Purchase Average Calculator after each purchase to assess her average cost. Initially, she bought 50 shares at $100 each. After a market downturn, she bought another 100 shares at $90. By calculating her average purchase price, she confidently decides to hold her position, seeing her cost basis decrease.
Result Interpretation and Outcome: Sarah’s average cost dropped to $93.33, which she notes is below the current market price, validating her strategy. She uses this information to plan her next investment move.
In alternative scenarios, an investor might use the calculator to decide whether to sell part of their holdings if their average purchase price exceeds the current market price.
