1. What is Average Cost Basis?

Average Cost Basis is a method used to calculate the average price per unit of a mutual fund investment. It represents the total amount invested divided by the total number of units owned, providing a simple way to determine the average purchase price across multiple transactions.

2. How Does the Calculator Work?

The calculator uses the Average Cost Basis formula:

Where:

• Total Investment — Sum of all money invested in the mutual fund ($)
• Units — Total number of mutual fund units owned

Explanation: This calculation helps investors understand their average purchase price per unit, which is essential for tracking investment performance and calculating capital gains or losses.

3. Importance of Average Cost Basis Calculation

Details: Calculating average cost basis is crucial for tax reporting purposes, investment performance analysis, and making informed decisions about when to buy or sell mutual fund units. It provides a clear picture of your investment cost structure.

4. Using the Calculator

Tips: Enter the total amount invested in dollars and the total number of mutual fund units owned. Both values must be positive numbers greater than zero for accurate calculation.
