How It Works
Enter current stock price, call option strike price, premium received per share, and days to expiration. The calculator annualizes premium income as covered call yield and shows return if assigned versus if option expires worthless. Typical retail strategy sells slightly out of the money calls thirty to forty five days out. Dividend paying underlyings may see early assignment before ex dividend if call is deep in the money. Model assignment risk separately when holding dividend aristocrats with short dated calls through ex date. Weekly covered calls on large cap ETFs like QQQ generate higher turnover and transaction costs than monthly cycles. Compare net annualized yield after estimated commission drag when scaling income strategy. Enter out of the money strike above spot for typical income strategy where assignment acceptable at strike price plus premium.
Review annualized yield, return if called away, return if not called, and break even price on underlying shares. Break even equals current price minus premium: stock can fall by premium amount before net loss on combined stock plus premium position. Rolling calls forward before expiry captures additional premium but adds transaction costs and gamma risk. Compare static thirty day cycle annualized yield against rolled forty five day cycles on same underlying. Compare annualized yield across thirty, forty five, and sixty day expiries on same underlying to see term structure of premium income versus assignment probability tradeoff before entering covered call program. Roll decision before expiry weighs remaining theta against assignment risk when spot approaches strike near expiration week.

The Formula
annualizedYieldPct = (premium / strikePrice) × (365 / daysToExpiry) × 100
staticReturnIfCalledPct = ((strikePrice - currentPrice + premium) / currentPrice) × 100
staticReturnIfNotCalledPct = (premium / currentPrice) × 100
breakEvenPrice = currentPrice - premium
Annualized yield scales premium over days to expiry. Called return includes assignment at strike. Break even subtracts premium from stock price. Does not model early assignment or dividends. Assignment at expiry occurs when spot exceeds strike plus dividend adjustment on standard equity options.
