1. What Is Average Cost Basis?

Average Cost Basis is a method used to calculate the average price per share of mutual fund holdings by dividing the total cost of all shares by the total number of shares owned. This method is commonly used for tax lot averaging in mutual fund investments.

2. How Does The Calculator Work?

The calculator uses the Average Cost Basis formula:

\[ \text{Avg Cost Basis} = \frac{\text{Total Cost}}{\text{Total Shares}} \]

Where:

\( \text{Total Cost} \) — Total amount invested in the mutual fund (currency)
\( \text{Total Shares} \) — Total number of shares owned (shares)

Explanation: This calculation provides the average price paid per share across all purchases, which is essential for determining capital gains or losses when selling shares.

3. Importance Of Average Cost Basis Calculation

Details: Accurate cost basis calculation is crucial for tax reporting, determining capital gains or losses, making informed investment decisions, and tracking investment performance over time.

4. Using The Calculator

Tips: Enter the total cost of all mutual fund purchases in currency and the total number of shares owned. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between average cost basis and specific identification?
A: Average cost basis calculates an average price across all shares, while specific identification allows you to choose which specific shares to sell at their individual purchase prices.

Q2: Can I change my cost basis method after using it?
A: For mutual funds, once you elect the average cost basis method, you generally cannot change it without IRS approval for that specific fund.

Q3: How does average cost basis affect taxes?
A: It determines your capital gains when selling shares. A higher cost basis results in lower capital gains and potentially lower taxes.

Q4: Should I include reinvested dividends in the total cost?
A: Yes, all purchases including reinvested dividends should be included in both total cost and total shares calculations.

Q5: Is average cost basis mandatory for mutual funds?
A: No, it's one of several acceptable methods, but once chosen for a particular fund, you must continue using it for all shares of that fund.
