Cash secured put calculator built in Excel, 3 metrics most sellers miss

About this tutorial
Cash secured put calculator built live in Excel using MarketXLS gives options income traders a repeatable, data-driven way to evaluate every potential trade before committing capital. This session walks through constructing the full calculator from scratch inside a real spreadsheet, pulling live options chain data with MarketXLS functions so every figure updates in real time. Whether you sell puts for income on a weekly basis or use the strategy to acquire shares at a discount, this demo shows you exactly how to size and score each trade objectively. What you'll see: - Pulling a live options chain for any ticker using MarketXLS functions and isolating put contracts by strike, expiration, and open interest directly in Excel - Calculating annualized return on capital for each candidate strike so you can compare trades across different tickers on an apples-to-apples basis - Building a break-even price cell that factors in the net premium received, giving you an instant downside buffer percentage against the current stock price - Scoring each put contract by implied volatility rank so you can filter for strikes where option premiums are historically elevated rather than just nominally high - Adding a collateral requirement column that auto-calculates the cash you must hold per contract, letting you stress-test position sizing against your actual account balance - Flagging contracts where the delta exceeds a user-defined threshold, the one check that separates disciplined sellers from traders who chase yield without measuring assignment probability Understanding these figures changes how you approach every trade. Annualized return looks attractive on paper, but without implied volatility rank and delta side by side you have no way to know whether the premium compensates you fairly for the risk you are taking on. A strike that pays a 1.2 percent monthly premium on a stock with low implied volatility rank is a very different trade than the same premium on a stock sitting at the 80th percentile of its volatility range. The calculator surfaces that contrast instantly, which means you spend less time guessing and more time acting on trades that actually meet your criteria. For anyone managing a wheel strategy or using cash secured puts as a core income method, having this dashboard open during market hours means you can evaluate new opportunities the moment they appear without rebuilding your math from scratch each time.
