How to Use the ROI Calculator - Evaluate Any Options Trade in Seconds
The SecurePutCalls ROI Calculator — also called the Options Analyzer — gives you a complete financial breakdown of any cash-secured put or covered call trade in seconds. This tutorial covers how to input a trade, interpret all the numbers the calculator produces, and use the results to make confident, informed trading decisions rather than relying on gut feel or incomplete analysis.
To analyze a trade, enter the underlying stock ticker, select the option type (put for cash-secured put, call for covered call), enter the strike price and expiration date, and the calculator auto-populates the current market premium. All key metrics are immediately displayed: the annualized ROI based on the premium collected divided by the capital at risk, the maximum profit, the breakeven stock price, and the probability of profit based on the option's implied volatility. The payoff diagram shows visually how the trade performs across all possible stock prices at expiration.
The Greeks section shows delta (how much the option's value changes per dollar move in the stock), theta (daily time decay in your favor as the seller), and vega (sensitivity to implied volatility changes). For wheel strategy income traders, theta is your primary friend — it represents the rate at which you earn premium each day the position is held. The calculator also shows the expected move for the stock through expiration, helping you assess whether your strike price provides sufficient buffer against normal price fluctuations.
