Enter Covered Call Details
Formula Used
The calculator analyzes the covered shares linked to sold call contracts. Covered shares equal contracts sold multiplied by shares per contract.
Net premium equals premium per share multiplied by covered shares, minus commissions and fees.
Breakeven price equals cost basis minus premium per share, minus dividend per share, plus commission per covered share.
Profit at expiration equals the smaller of final price or strike price, minus cost basis, multiplied by covered shares. Net premium and dividend income are then added.
Maximum profit equals strike price minus cost basis, multiplied by covered shares. Net premium and dividend income are added.
Maximum loss assumes the covered shares fall to zero. It equals total cost basis minus net premium and dividend income.

Covered Call Planning Guide
What It Calculates
A covered call combines owned shares with a sold call option. The goal is income. The trade also accepts a price cap. This calculator helps compare that balance before an order is placed.
The inputs start with share cost, current price, strike, premium, contracts, commissions, dividends, and days left. These values describe the trade. They also show how much stock is covered by the call.
Profit comes from three sources. Premium is received first. Dividends may be earned if the shares are held. Stock profit is limited when the final price rises above the strike. At that point, assignment sells the covered shares at the strike.
Risk And Return
Risk remains important. A covered call is not a protected trade. Premium lowers the breakeven price, but the stock can still fall sharply. The maximum loss estimate assumes the covered shares fall to zero. That case shows capital exposure.
Return numbers help compare trades. The calculator reports income yield, maximum return on cost, and annualized return. Annualized figures are useful, but they can overstate results when repeated trades are not available. Use them as comparison tools, not promises.
Scenario Review
Scenario results add context. A price below breakeven shows a loss. A price between breakeven and strike shows partial or full profit. A price above strike shows the capped result after the short call offsets further stock gains.
Use the assignment status carefully. Assignment can happen before expiration, especially around dividends or deep in the money options. The calculator gives an expiration estimate. Real fills, taxes, spreads, and early exercise can change the outcome.
Practical Use
A strong covered call setup usually starts with a stock you are willing to own. It also uses a strike where selling feels acceptable. If the strike is too low, upside may be sacrificed. If it is too high, income may be small.
The best use is comparison. Test several strikes. Change the premium. Adjust days left. Compare risk, yield, and capped profit. Then choose a trade that fits your stock view, income goal, and risk limit. Record estimates before trading. Review them after expiration. This habit improves discipline, entry selection, and future strike choices for income plans.
FAQs
What is a covered call?
A covered call is a strategy where you own shares and sell call options against them. The premium creates income, while the strike price limits upside if assignment occurs.
What does breakeven mean here?
Breakeven is the adjusted stock price where the position reaches zero profit. It subtracts premium and dividend income from cost basis, then adds commission per covered share.
Can maximum profit be capped?
Yes. Covered call profit is capped near the strike price. Above that price, the short call offsets extra stock gains, and the shares may be assigned.
Does this calculator include commissions?
Yes. The commission field reduces net premium. It also affects breakeven, maximum profit, maximum loss, and return percentages.
Why enter shares owned?
Shares owned confirm whether the call position is fully covered. If contracts control more shares than you own, the calculator shows an uncovered share warning.
What is annualized return?
Annualized return converts the trade return into a yearly rate using days to expiration. It is useful for comparison, but it is not a guaranteed yearly result.
Can assignment happen early?
Yes. Early assignment can happen before expiration, especially when options are deep in the money or dividends are near. This calculator gives an expiration estimate.
Is a covered call risk free?
No. Premium lowers risk, but stock downside remains. If the stock falls sharply, losses can be much larger than the option income received.
