How to use it
Enter your stock price (or cost basis), the call strike you’re selling, the premium per share, the number of contracts, and days to expiration. The calculator returns your static return (if the stock is unchanged), the annualized version, the return if you’re called away, and the premium income in dollars.
The math
static return = premium ÷ stock price, if-called = (strike − price + premium) ÷
price, and annualized = static × 365 ÷ days. Selling a $105 call for $2 against
$100 stock is a 2% static return (24.3% annualized over 30 days), a 7% return if called, with a
$98 breakeven.
