1. What Is Adjusted Cost Basis?

Adjusted Cost Basis (ACB) is the average cost per share of an investment, adjusted for various transactions like additional purchases, returns of capital, and other adjustments. It's particularly important for Canadian tax purposes when calculating capital gains or losses.

2. How Does The Calculator Work?

The calculator uses the ACB formula:

\[ ACB = \frac{(Cost + Additions - Returns)}{Shares} \]

Where:

\( Cost \) — Initial investment cost in currency
\( Additions \) — Additional investment amounts in currency
\( Returns \) — Returns of capital or distributions in currency
\( Shares \) — Total number of shares held

Explanation: The formula calculates the average cost per share after accounting for all capital transactions, which is essential for accurate capital gains reporting.

3. Importance Of ACB Calculation

Details: Accurate ACB calculation is crucial for determining capital gains or losses for tax purposes, ensuring proper tax reporting, and maximizing after-tax investment returns.

4. Using The Calculator

Tips: Enter all monetary values in the same currency, ensure share count is accurate, and include all relevant transactions. All values must be valid (non-negative amounts, positive share count).
