1. What Is Average Stock Purchase Price?

The Average Stock Purchase Price, also known as cost basis, represents the average price per share you've paid for all shares of a particular stock in your portfolio. It's calculated by dividing the total amount invested by the total number of shares owned.

2. How Does The Calculator Work?

The calculator uses the average price formula:

Where:

• \( \text{Total Cost} \) — Total amount invested in the stock (currency)
• \( \text{Total Shares} \) — Total number of shares owned (unitless)
• \( \text{Average Price} \) — Cost basis per share (currency/share)

Explanation: This calculation helps investors determine their break-even point and assess investment performance by comparing the average purchase price to current market prices.

3. Importance Of Cost Basis Calculation

Details: Knowing your average purchase price is essential for calculating capital gains/losses for tax purposes, making informed selling decisions, and tracking investment performance over time.

4. Using The Calculator

Tips: Enter the total amount you've invested in the stock and the total number of shares you own. Ensure both values are positive numbers for accurate calculation.
