How a covered call pays
You own the shares and you sell someone the right to buy them from you at the strike. The premium is yours the moment the trade fills. What you give up is everything above the strike, because from that price upward each extra dollar the stock gains is a dollar the call buyer takes. The position therefore trades an unknown amount of future upside for a known amount of cash today.
The worked example behind the defaults
The calculator loads with 100 shares bought at $48.50, a $52.50 call sold for $1.35, 45 days to expiry and a $0.22 dividend with an ex-date inside the holding period.
Cost of shares = 100 x 48.50 = $4,850
Premium collected = 100 x 1.35 = $135
Net debit = 4,850 - 135 = $4,715
Your real cost per share is $47.15, and the dividend pulls the breakeven down another 22 cents to $46.93. Below that price the position loses money.
If the stock does nothing and finishes at $48.50, the call expires worthless and you keep the premium and the dividend: $157 on a $4,715 outlay, a static return of 3.33%. Scaled to a year, 3.33% x 365/45 = 27.0%.
If the stock finishes anywhere above $52.50 the shares are called away. You collect the $4 of price gain, the $1.35 premium and the $0.22 dividend, which is $5.57 a share or $557 on the position. That is 11.81% of the net debit, or 95.8% annualized. It is also the ceiling. A move to $60 pays exactly the same $557 as a move to $53.
Reading the annualized numbers honestly
A 95.8% annualized if-called return describes a 45 day result stretched over a year. Earning it would take this exact trade appearing eight times in a row and working every time. In practice the stock moves, the next strike sits somewhere else, and volatility changes what the premium is worth. Annualizing is a comparison device for ranking candidates of different lengths, and the covered calls guide shows how the ranking shifts once assignment is factored in.
Strike selection and early assignment
Move the strike closer to the current price and the premium rises, the static return rises, and the if-called return falls because there is less price gain to capture. Move it further away and the reverse happens. The strike you choose is a statement about how likely you think a rally is, which is the same judgement the option's delta expresses numerically. The Greeks calculator gives you that delta, and option Greeks explained covers why traders treat it as a rough probability of finishing in the money.
Early assignment is the detail most new sellers miss. American style calls can be exercised any day, and the usual moment is the evening before an ex-dividend date when the remaining extrinsic value in the call is smaller than the dividend. If your call is deep in the money going into an ex-date, expect to lose both the shares and the payout, which the dividend investing guide explains in terms of the price adjustment on the ex-date.
To see the same position drawn as one leg of a larger structure, or to compare it with a collar, use the options strategy builder. For the mirror image trade, where you sell a put and get paid to wait for a lower entry, read cash-secured puts. If you are new to the mechanics, start with options trading for beginners.
Frequently asked questions
What is a covered call?
A covered call is owning at least 100 shares of a stock and selling one call option against them. You collect the premium immediately. In exchange you agree to sell the shares at the strike price if the buyer exercises, which caps your upside above that strike.
What is the difference between static and if-called return?
Static return assumes the stock sits still and the call expires worthless, so your profit is the premium plus any dividend. If-called return assumes the stock finishes above the strike and the shares are sold, adding the gain up to the strike. If-called is the higher of the two whenever the strike sits above your cost.
Why annualize a 45 day trade?
Annualizing puts positions of different lengths on one scale so a 30 day call and a 90 day call can be compared. It does not promise the rate is repeatable. You would need the same premium available twelve times over, at the same strike distance, for the annualized figure to be earned.
What happens to my dividend if the call is assigned early?
A deep in the money call is most likely to be exercised early on the day before the ex-dividend date, because the holder wants the dividend. If that happens you lose both the shares and the dividend. The risk rises when the remaining extrinsic value is smaller than the dividend.
Which strike should I sell?
A strike close to the current price collects more premium but caps the upside almost immediately and is assigned more often. A further out strike collects less and leaves room to run. The trade off is between income today and the size of the gain you are prepared to give away.
Can a covered call lose money?
Yes. The premium cushions a fall but it does not stop one. If you buy at 48.50 and collect 1.35, you are still long the stock below 47.15 and you carry the full loss down to zero. The option only limits how much of a rally you keep.
