COVERED_CALL_CALCULATOR
Calculate the income, yield, and risk of a covered call. Enter your share price, strike, and the premium you'd collect — the calculator shows annualized yield, breakeven, return if assigned, and the payoff at expiration.
How This Calculator Works
A covered call combines 100 shares of stock with one short call option. You keep the premium no matter what; in exchange, your upside is capped at the strike price. The formulas used here:
- → Breakeven = share price − premium
- → Max profit = (strike − share price + premium) × 100 × contracts
- → Premium yield = premium ÷ share price
- → Annualized yield = premium yield × (365 ÷ days to expiration)
- → Return if assigned = (strike − share price + premium) ÷ share price
FAQ
How is covered call yield calculated?
Premium yield is the option premium received divided by the share price. For example, collecting $2.00 per share on a $100 stock is a 2% yield. Annualized yield multiplies that by 365 divided by days to expiration — a 2% yield over 30 days annualizes to roughly 24%.
What is the breakeven price on a covered call?
Breakeven equals your share cost minus the premium received. If you buy shares at $100 and collect $2.00 in premium, you don’t lose money unless the stock falls below $98 at expiration.
What is "return if assigned"?
If the stock closes above the strike at expiration, your shares are called away at the strike price. Return if assigned = (strike − share price + premium) ÷ share price. It is the total return of the trade in its best case, including capital appreciation up to the strike plus the premium.
What is the maximum loss on a covered call?
The maximum loss is the full cost of the shares minus the premium received, which occurs only if the stock goes to zero. The short call itself doesn’t add risk — it caps your upside in exchange for income.
