1. What is Average Cost Basis?

Average Cost Basis represents the average price per share paid for all shares of a particular stock in your portfolio. It is calculated by dividing the total cost of all shares by the total number of shares owned.

2. How Does the Calculator Work?

The calculator uses the average cost basis formula:

Where:

• \( \text{Total Cost} \) — Sum of all purchase costs for the stock (currency)
• \( \text{Total Shares} \) — Total number of shares owned (shares)
• \( \text{Avg Basis} \) — Average purchase price per share (currency/share)

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

3. Importance of Average Cost Basis

Details: Knowing your average cost basis is essential for making informed investment decisions, calculating capital gains or losses for tax purposes, and developing effective investment strategies.
