First-In First-Out Method
The First-In First-Out (FIFO) method is an accounting convention that assumes the first assets purchased are the first ones sold. When calculating capital gains, this method uses the cost basis of the oldest assets in the portfolio to determine the profit from a sale.
In a rising market, FIFO typically results in higher realized gains compared to other methods because the oldest assets were often purchased at lower prices. Conversely, in a falling market, it might result in lower gains or larger losses.
FIFO is often the default method used by many financial institutions and is straightforward to implement for tax reporting. Investors should be aware of how their choice of accounting method affects their tax bill and choose the one that aligns with their overall financial goals.
