What Is a Cash-Secured Put? A cash-secured put is an options strategy where we sell a put option while keeping enough cash to buy 100 shares of the underlying stock if we are assigned. This strategy is often used to: • Generate regular premium income • Buy stocks at lower effective prices • Increase portfolio yield • Lower the cost basis on long-term holdings • Enter positions with clear risk limits Unlike naked puts, cash-secured puts keep fully reserved collateral, making them one of the safest income-focused options strategies available. How a Cash-Secured Put Works When we sell a put option: We receive an upfront premium We agree to buy shares at the strike price if assigned Our maximum profit equals the premium received Our effective purchase price becomes the strike price minus the premium collected Example Outcomes Option Expires Worthless If the stock stays above $100 at expiration: We keep the full $300 premium No shares are assigned Maximum profit is realized Option Assigned If the stock falls below $100: We purchase 100 shares at $100 Effective cost basis becomes $97 Premium offsets part of the decline Why Traders Use a Cash-Secured Put Calculator Manual calculations lead to mistakes in position sizing, return projections, and assignment risk analysis.

Key Metrics a Cash-Secured Put Calculator Should Include 1. Premium Income Premium income represents the immediate cash received from selling the put option.

Breakeven Price The breakeven price identifies the effective stock purchase cost after accounting for the premium received. Formula Breakeven = Strike Price − Premium Received Example $95 − $2.20 = $92.80 A lower breakeven provides greater downside protection. 3. Maximum Profit The maximum possible gain occurs when the option expires worthless. Formula Maximum Profit = Premium Collected Unlike covered calls, the upside is capped at the premium amount. 4.
