How a Covered Call Can Collect Premium and Still Lose Money
Suppose you buy 100 shares at $100 each and sell a $105 call for $2 per share. You collect $200, but if the stock falls to $80 by expiration and the call expires unused, the shares lose $2,000. The combined loss is $1,800, even though the option made money.
The premium offsets part of the stock loss. To see the whole result, follow both positions rather than counting only the cash received for selling the call.
The ledger includes the shares and the call
This hypothetical buy/write opens a new stock holding and a short call together. It uses one standard U.S. equity call covering the same 100 shares you purchase. 1
The prices are constructed examples, not live quotations or calculator outputs. All calculations below exclude fees, dividends, financing and taxes. The main comparison runs from opening through the call’s expiration.
| Opening transaction | Cash flow |
|---|---|
| Buy 100 shares at $100 | −$10,000 |
| Sell one $105 call for $2 per share | +$200 |
| Net opening cash flow | −$9,800 |
The $200 receipt reduces the net opening outlay to $9,800, but it leaves an open call obligation. Buying back the call can cost money, and assignment requires selling the shares at the strike. The opening receipt alone is not the option’s final profit. 2
Here is the result at four expiration prices:
| Stock price at expiration | Stock P/L | Short-call P/L | Combined P/L |
|---|---|---|---|
| $80 | −$2,000 | +$200 | −$1,800 |
| $100 | $0 | +$200 | +$200 |
| $105 | +$500 | +$200 | +$700 |
| $110 | +$1,000 | −$300 | +$700 |
All amounts are dollars for the complete 100-share position. Stock P/L measures the change from the $10,000 purchase cost. Short-call P/L includes the $200 premium, less the call’s expiration intrinsic value multiplied by 100.
At $80, the remaining shares are worth $8,000 against the $9,800 net opening outlay. If you still hold them, their loss is unrealized, but it still belongs in the combined valuation. Counting only the expired call’s profit would omit the larger loss on the shares.
Why gains stop at $700
At $110, the shares have gained $1,000, but the $105 call has $500 of intrinsic value against you. After the $200 opening premium, the short call has lost $300, leaving a $700 combined profit. Above $105, every additional dollar of stock gain is offset by another dollar of call obligation.
The maximum expiration profit is therefore $700, reached at $105 or above. At exactly $105, that maximum-payoff arithmetic does not promise exercise or assignment. 3 2
If assigned, you deliver the 100 shares you already own at $105 and receive $10,500. You do not sell them at the $110 market price and separately pay a $500 cash-settlement charge: these equity options settle through shares. 1
The assignment cash ledger is:
There is no further intrinsic-value deduction. Selling at $105 instead of $110 already accounts for the call’s effect. The table separates the legs for valuation; the delivery ledger records the actual share sale. Both reach the same total.
Standard U.S. equity calls are American-style, so assignment can occur before expiration and end the stock exposure earlier. If the call instead expires without assignment and you retain the shares, their later gains or losses belong to the continuing stock position, outside this opening-to-expiration comparison. 1 2
Break-even is $98; most of the downside remains
The premium offsets the first $2 per share of a stock decline. At $98, the $200 stock loss exactly matches the $200 option gain, giving the expiration break-even. Below $98, the combined position loses money.
If the stock becomes worthless, the shares lose $10,000 and the call has no intrinsic value. The premium reduces the maximum loss to $9,800. “Covered” means the shares can meet the call’s delivery obligation, not that their purchase value is protected. These break-even and loss relationships follow the standard buy/write payoff. 3
Let be the stock price at expiration. Adding the stock’s price change and the premium, then subtracting the call payoff, gives:
Closing early uses actual prices for both legs
Before expiration, the call can retain time value even when the stock is below $105. A complete exit sells the shares and buys back the call, so use both actual execution prices rather than the call’s intrinsic value alone. 3
Let be the per-share stock sale price and the per-share call repurchase premium:
For example, suppose you can sell the shares for $95 each and buy back the call for $0.50 per share. These hypothetical closing prices produce a $500 stock loss and a $150 option profit, for a $350 combined loss. The $50 repurchase cost matters even though the call is out of the money.
Using valuation marks instead of executions gives a snapshot of P/L, not a completed trading result. Buying back only the call leaves the shares open; selling only the shares while the call remains open removes its cover. 3
The same $700 gain can be 7% or 7.14%
If the position earns its $700 maximum expiration profit, the percentage depends on the denominator:
| Return basis | Calculation | Opening-to-expiration return |
|---|---|---|
| Gross share purchase cost | $700 ÷ $10,000 | 7.00% |
| Net opening outlay | $700 ÷ $9,800 | About 7.14% |
The first measures profit against the full share purchase cost. The second measures it against the cash outlay after receiving the premium. Neither changes the $700 gain.
The $200 premium alone is 2% of the gross share cost, but that is a premium-to-share-cost percentage, not the combined position’s return. It leaves the stock result and any call-closing obligation out of the numerator.
Both returns in the table cover the opening-to-expiration period. No particular number of days is assumed, and neither percentage is annualized. An early close or assignment has its own measurement endpoint. A broader realized-return calculation must also include the relevant cash receipts and expenses excluded from this example, over the same measured holding period.
The $100 share price here is the new purchase at the start of the buy/write, not a historical holder’s tax basis. See Options Profit vs. Return for how different denominators answer different questions.
What Options Calculator can show
Options Calculator has options-only legs and model-derived premiums, not a stock leg or a fixed actual-fill input. Entering a short call alone omits the shares and cannot reproduce this complete covered-call ledger. See the methodology for details.
For the underlying rights and obligations, see Calls. The Short Call guide explains the option leg separately, including what changes when it is uncovered.
