Building a Covered Call Calculator in Excel
Microsoft Excel is one of the best tools for covered call analysis because it allows you to create custom calculators, track trades over time, and build scenario analysis that adapts to your specific strategy. This guide provides the exact Excel formulas you need to build a professional covered call calculator from scratch, including profit/loss, breakeven, returns, and annualized yield.
Whether you prefer Excel on desktop or Microsoft 365 online, these formulas work in all versions. You can also adapt them for Google Sheets with minimal changes (the syntax is nearly identical).
