Cost Base Per Share

Understanding and Calculating the Cost Base Per Share

In the world of investing, keeping track of your gains and losses is crucial. Not only does this allow you to evaluate your investment strategy's effectiveness, but it also has significant tax implications. One of the key metrics that helps investors determine their capital gains or losses is the "cost base per share". Let's delve deeper into what it is and how it's calculated.

What is Cost Base Per Share?

The cost base of an investment refers to its original value for tax purposes. This figure is typically the purchase price of the asset but can be adjusted due to several corporate actions including stock splits, dividends, and return of capital distributions. The cost base also takes into account any associated costs incurred during the purchase, holding, or selling of the asset, like brokerage fees.

The cost base per share is simply the total cost base of your investment divided by the number of shares you hold. It is a crucial figure when calculating capital gains (or losses), which are determined based on the difference between the investment's cost base and its current market value. Knowing the cost base per share of your stocks becomes particularly important when you sell shares, as it can significantly impact your tax situation.

How is Cost Base Per Share Calculated?

While the basic calculation of the cost base per share is straightforward (total cost base divided by the number of shares), it can become more complex when corporate actions come into play.

Case of a Stock Split

For instance, let's consider a company that has undergone a 2:1 stock split. You originally purchased 500 shares at $10 per share, so your original investment value, or cost base, is $5,000. After the stock split, you now hold 1,000 shares.

To calculate your new cost base per share, you would divide the original cost base ($5,000) by your new total number of shares (1,000). The result is a cost base per share of $5, reduced from your initial cost base per share of $10.

Other Corporate Actions

But what about other corporate actions such as stock dividends and return of capital distributions? These also have implications for your cost base per share.

If a company issues a return of capital to its shareholders, the cost base per share typically decreases. This is because a return of capital reduces the original cost of the investment but is not considered a taxable event.

On the other hand, if a dividend is paid in the form of additional shares (known as a "stock dividend"), the cost base per share can also change. The original cost base must now be spread across a larger number of shares, thus reducing the cost base per share. Regular dividends don’t impact the cost base of your shares. 

Final Thoughts

Understanding and accurately calculating your cost base per share is essential for keeping track of your investments and for tax purposes. Given the potentially complex nature of these calculations, particularly when corporate actions are involved, it's crucial to keep accurate records.
