The Last In, First Out (LIFO) method is an accounting method used to calculate the cost basis of a stock portfolio. It is the opposite of the First In, First Out (FIFO) method, where the oldest shares are sold first. In the LIFO method, the most recent shares are sold first. In the previous post Compute cost basis of stocks with FIFO method in Google Sheets , I explained how to implement FIFO method in Google Sheets to compute cost basis in stocks investing. In this post, I explain how to implement LIFO method in Google Sheets to compute cost basis in stocks investing.

To effectively track a stock investment portfolio, it is necessary to know its evolution in the past. As I use Google Sheets to track my stock investment portfolio, I have researched and successfully implemented several solutions. In this post, I am happy to share in detail how to compute the daily evolution of a stock investment portfolio by simply using only the available built-in functions in Google Sheets.

Anyone using Google Sheets to manage stock portfolio investment must know how to use the GOOGLEFINANCE function to fetch historical prices of stocks. As I have used it extensively to manage my stock portfolio investment in Google Sheets , I have learned several best practices for using the GOOGLEFINANCE function that I would like to share in this post.

After selling a portion of my holdings in a stock, the cost basis for the remain shares of that stock in my portfolio is not simply the sum of all transactions. When selling, I need to decide which shares I want to sell. One of the most common accounting methods is FIFO (first in, first out), meaning that the shares I bought earliest will be the shares I sell first. As you might already know, I use Google Sheets extensively to manage my stock portfolio investment, but, at the moment of writing this post, I find that Google Sheets does not provide a built-in formula for FIFO. Luckily, with lots of effort, I succeeded in building my own FIFO solution in Google Sheets, and I want to share it on this blog. In this post, I explain how to implement FIFO method in Google Sheets to compute cost basis in stocks investing.
