World-Leading Covered Calls Calculator & Simulator

DeshCap · Portfolio Income Engineering

Covered Call Strategy Designer

Build, simulate, and stress-test a covered call income strategy against your own portfolio and goals. Free — educational — not investment advice.

⚠️ This tool does not pull live market data. Enter your own current price and option premium from your brokerage, or use the built-in theoretical estimator. Historical scenarios are illustrative stress tests, not a live backtest engine. Nothing here is investment, tax, or legal advice.

Step 1 · Your Portfolio Position

Covered calls are written against shares you already own (or intend to buy in 100-share lots). Enter the position you want to design a strategy around.

Each contract covers 100 shares

Step 2 · Goals

Your goal shapes how aggressively the strategy should sell calls. Income-focused strategies sell closer to the money for higher premium; growth-focused strategies sell further out to preserve upside.

Step 3 · Your Market Outlook

Your view on where the stock is headed determines how far out-of-the-money to strike your calls, and how much room you leave for upside before assignment.

Step 4 · Design Your Strategy

Choose your strike distance and expiration. Enter the actual premium quoted by your broker, or toggle the theoretical estimator if you want to model a hypothetical trade.

🗃 Historical Scenario Stress Test

Apply a real historical market environment to see directionally how this strategy would have behaved. Illustrative only — not a live backtest of actual option prices from that period.

Step 6 · Compare Strategies

Save your current configuration, then adjust Step 4 and save again to compare strike/expiration combinations side by side.

Want This Engineered Properly — Not Just Modeled?

This tool shows you the mechanics. A real covered call income programme accounts for tax treatment, assignment management, rolling strategy, position sizing across your full portfolio, and downside hedging — things a spreadsheet can't do for you.

Design My Income Strategy ↓

Methodology: Black-Scholes estimator assumes European-style exercise and constant volatility; actual American-style equity options may price differently, particularly around dividends and early assignment. Historical scenarios apply the stated price move to your current inputs and do not reflect actual historical implied volatility, bid-ask spreads, or option liquidity at that time. All figures are before taxes, commissions, and assignment fees. This tool is for education only and does not constitute investment, tax, or legal advice — consult a licensed advisor before implementing any options strategy.
