I have explained the idea of using Google Sheets functions to calculate internal rate of return (IRR) and net present value (NPV) for a stock portfolio . The process consists mainly of three steps: Identify cash flows from transactions managed in a Google Sheets spreadsheet Choose a discount rate based on personal preferences Apply XIRR and XNPV functions of Google Sheets In this post, I demonstrate step-by-step how to apply this process to calculate internal rate of return (IRR) and net present value (NPV) for a stock portfolio at 3 levels.
