With most things in life, it helps to be covered — by a coworker, an insurance policy, or a roof over your head. In investing, it can also be helpful to have coverage through specific strategies. A covered call is an options trading strategy that involves selling call options on stocks you already own, with the goal of generating income. It is typically appropriate to use when an investor has a neutral to slightly bullish outlook on the underlying stock.
Here’s a breakdown of how a covered call strategy works, when to consider it, and how it may — or may not — perform depending on market positions.
Key Points
• A covered call strategy involves selling call options on owned stock to generate income, with limited upside if the stock’s price surges.
• Using covered calls provides additional income from stock holdings through the premiums received from selling a call option.
• Premiums from covered calls offer limited protection against stock price declines, which helps offset potential losses in whole or in part.
• Capped gains risk occurs if the stock price rises above the call option’s strike price. The investor will collect any gain between — but not above — the stock purchase price and the strike price.
• Covered call writers can select their exit price (i.e., the strike price plus the premium received) in the event the stock price were to rise. If the stock rises above the strike price, the investor keeps both the premium and the gain between the stock purchase price and the strike price.
• Employing covered calls restricts the ability to sell stocks freely, as the call option must either be sold first or honored if held and the buyer exercises it.
• An investor with an objective of generating income may purchase stock they wish to hold in their portfolio and simultaneously sell a covered call to generate income. This is sometimes called a buy/write strategy.
What Is a Covered Call?
A covered call is an options trading strategy used to generate income by selling call options on a security an investor already owns or decides to purchase. This strategy can be beneficial to the investor if they expect the stock’s price to experience limited movement or remain neutral, though it may limit potential gains if the stock rises sharply above the strike price.
Call Options Recap
A call is a type of option that gives purchasers the right, but not the obligation, to buy shares of an underlying asset or stock at a specific, prearranged price, called the strike price. A call is in contrast to a put option, which gives buyers the right, but not the obligation, to sell the underlying asset at the strike price.
An investor who purchases a call option holds a long position in the option — that is, they anticipate that the underlying stock may appreciate. For example, an investor who anticipates a stock’s price increase might buy shares, hold them, wait for appreciation, and — assuming they do appreciate — sell them to potentially realize a gain.
Call options allow options buyers to pursue a similar strategy without buying the underlying shares. Instead, a premium is paid for the right to buy the shares at the strike price, allowing buyers to profit if the market price rises above the strike price.
Call option writers (or sellers), on the other hand, typically sell call options when they anticipate that the price of the underlying asset will not rise above the strike price, allowing them to keep the premium, or price they collected for selling the option, when the option expires worthless.
What’s the Difference Between a Call and a Covered Call?
The main difference between a regular call and a covered call is that a covered call is “covered” by an options seller who holds the underlying asset. That is, if an investor sells call options on Company X stock, it would be “covered” if they already own an equivalent number of shares in Company X stock.
Conversely, if an investor does not own any Company X stock and sells a call option, they’re executing what’s known as a “naked” option, which carries a much higher risk because losses can theoretically be unlimited if the stock rises sharply. The covered call strategy combines and leverages the owned stock to limit risk and allow them to sell a call to collect premium.
In a covered call, the seller’s maximum profit is limited to the premium plus any stock appreciation up to the call’s strike price, while the maximum loss equals the price paid for the stock minus the premium received.
In contrast, in a portfolio where the investor is only holding the stock, the maximum profit is theoretically unlimited, based on how high the stock price trades minus the price paid for the stock. The maximum loss is the price paid for the stock minus the stock’s lowest trading price (theoretically zero, which would equal the whole value of the position).
It’s worth noting that similar to only holding stock, the losses with covered calls would also be substantial if the price of the stock purchased were to fall to zero and became worthless. However, the premium received from the call option sold may cushion the loss to a certain extent.
Example of a Covered Call
The main goal in employing a covered call trading strategy is typically to generate income from existing (or newly acquired) stock positions. If, for example, you have 100 shares of Company X stock and were looking for ways to pursue additional income, you might consider selling a covered call.
Here’s what that might look like in practice:
Your 100 shares of Company X stock are worth $4.77 each, or $477 at the current market value. To make a little extra money, you decide to sell a call option with a $0.08-per-share premium at a strike price of $5.50 and 21 days to expiration. Since standard options contracts typically represent 100 shares, you receive a total of $8 for the option.
Let’s say that Company X stock’s price only rises to $5, so it expires worthless. In this scenario, you’ve earned a total of $8 by the selling covered call option, and your shares have also appreciated to a value of $500. So, you now have a total of $508.
Max Profit: The ideal outcome in this strategy is that your shares rise in value to the strike price of $5.50. In that scenario, you still own your shares (now worth $550) and get the $8 premium. Your profit is $81 ($558 – $477).
Capped Gain Risk: One risk of selling covered call options is that you might forgo higher gains if the stock exceeds the strike price. In this scenario, let’s assume the stock price rises above the strike to $6. The 100 shares of stock held is now worth $600, but since the option was exercised in the money at $550, the strategy will sell the stock for $550 and miss out on the extra $50 ($600 – $550) of stock appreciation value.
While this risk is slightly offset by the $8 collected by selling the option, it is easy to see that for each dollar increase above the strike price, the strategy will miss out on that gain. Effectively, you still have turned a holding valued at $477 into $558, but missed the extra gain of $50 beyond the strike price. This illustrates the trade-off involved in selling covered calls: capped upside in exchange for income.
Max Loss: Another risk of selling covered call options is that the stock price may drop. In this scenario, let’s assume the stock price drops to $4.00. The 100 shares of stock held is now worth $400. Your loss is -$77 ($400 – $477). This risk is slightly offset by the $8 collected by selling the option.
In a worst case scenario, the stock price could move to $0 and you could lose the entire stock value, while keeping the $8 premium you received by selling the covered call. If your long term outlook on the stock was positive, then you may still be OK holding the stock at this lower price level. If you only purchased the stock to support the covered call strategy, this loss would be realized as a loss of the capital invested.
Break Even: If the stock price drops by the amount of the premium, the investor breaks even on the trade. In this scenario $4.69 ($4.77 – $0.08) as the break-even stock price.
Income Generated: When selling a covered call, the premium received is income to the portfolio. In this scenario, the income generated is the premium of $8, which is realized at the time the call is sold.

How to Sell a Covered Call: A Step-by-Step Example
A covered call strategy consists of a defined sequence of steps that combine owning (or purchasing) a stock while also selling a call option against it. Here’s how to implement the strategy in a way that may help you generate additional income from your stock holdings.
Step 1: Own at Least 100 Shares of an Underlying Stock
First, you first need to own at least 100 shares of the stock you intend to write the call option upon. This minimum is required since options contracts typically represent 100 shares of the underlying security. Owning these shares is what “covers” your obligation if the call buyer decides to exercise the option.
Step 2: Sell-to-Open One Call Option Contract
Once you hold the required shares, you place a sell-to-open order for a call option against those shares. This creates an obligation for you to sell your shares at the specified strike price if the option buyer chooses to exercise the contract.
Step 3: Choose a Strike Price and Expiration Date
Selecting the strike price and the expiration date is a key decision in covered call writing.
• Strike price: Choose a price above the current market price if you want to retain some upside potential while collecting premium.
• Expiration date: Shorter expirations (e.g., 30–60 days) can offer frequent income opportunities, but may require more active management. Longer expirations typically provide higher premiums but may tie up your shares longer.
Both choices depend on your outlook for the stock and your income goals.
Step 4: Collect the Premium
After submitting the sell-to-open order, you’ll receive the option premium — the cash payment from the buyer of the call option. This premium is yours to keep regardless of whether the option is exercised. It effectively increases your total return on the stock during the period you wrote the call.
Step 5: Manage the Outcome at Expiration
When the call option approaches expiration, there are a few possible outcomes:
• Option expires worthless: If the stock stays below the strike price, the option likely expires worthless and you keep both your shares and the premium.
• Option is exercised: If the stock price rises above the strike price, the buyer may exercise the option. You would then sell your shares at the strike price and still keep the premium received.
• Rolling the option: Some investors choose to buy back the expiring call and sell a new one with a later expiration or different strike price if they want to continue generating income without losing their shares.
Key Decisions When Selling Covered Calls
There are a number of factors that could influence the value of an option. When writing a covered call and choosing the contract’s strike price and expiration, it’s important to understand the fundamentals of how options are priced.
Basic Options Valuation
When determining an option’s strike price and expiration, it is helpful to break down an option’s value into two main value buckets: intrinsic value and extrinsic value. An option’s price is the sum of its intrinsic value and extrinsic value:
• Options price = intrinsic value + extrinsic value.
An option’s intrinsic value is the tangible value that would be realized if it was exercised in the current moment. For a call option, it is the difference between the current price of the option’s underlying stock price and the option’s strike price.
• Call Option Intrinsic Value = Current price of underlying stock – strike price
An option’s extrinsic value is the difference between its market value and intrinsic value. An option’s estimated market value is influenced by its time until expiration and the anticipated volatility of the stock price between now and expiration.
As the time until expiration decreases, the time value of the option will decay since there is less time for the stock’s price to potentially move above the strike and put the call option in the money. This concept is called time decay.
In a covered call, the writer typically wants the option’s time value to decay to zero so they are able to keep the full premium. One other thing to note is that the closer the strike is to the current stock price, the more extrinsic value there will be in the option. This is because the option requires a smaller stock price movement to become in the money.
As with any trade, the decision comes down to a risk vs. reward tradeoff. The reward is the amount of premium that will be collected and the risk is the likelihood that the stock price will go above the strike price or fall below the value of the premium collected in the days leading up until expiration.
Choosing a Strike Price
In terms of the strike price, there are a few potential considerations an investor might evaluate. Typically, the investor would sell an out-of-the-money call to give the stock price room to move upward before they would be obligated to sell it.
1. The investor should generally be aware that as an option’s strike price becomes further away from the current stock price, there will be a smaller chance that the option may expire in the money, thus reducing that option’s value (the premium that could be received when selling the option contract).
2. The investor might have a target price where they would be willing to sell the stock if it reached that level. Using this price as the strike price would meet that target.
3. The investor might have a feel for the range of prices they believe the stock will stay between based on historical pricing, fundamentals, upcoming events, or other insights.
4. The investor might not want to sell a call that is already in the money unless they have a belief that the stock price will go down before expiration, or if they are willing to sell the stock at a loss to the current stock price in order to collect more premium than an out-of-the-money call would provide.
Choosing an Expiration
In terms of the expiration date, there are also a few potential considerations an investor might evaluate. Typically, the investor would sell a call that is between 15-60 days from expiration to balance the tradeoff between premium received vs. the time and volatility value or amount of time for the stock price to move.
1. The investor should generally be aware that as the expiration becomes further into the future, there will be more time for the stock price to move. That will typically translate into an increased options value or premium that could be received when selling the contract.
2. It’s possible that short duration contracts may not yield enough premium income to overcome the risk of a quick, unexpected stock price movement.
3. The investor might not want to have the prolonged exposure of a long-duration covered call, or they may notice that there is a diminishing return value for selling option contracts that expire too far into the future.
4. The investor might know that an event is coming up and want to ensure their covered call is not exposed to the potential price movement from that event.
Final Decision and Selling the Call
In practice, the covered call writer will want to look at the options chain to see the tradeoffs between the amount of premium they can receive or the potential reward for the risk associated with trading an option with a particular strike and expiration. The investor will use these inputs along with the other objectives they have for their portfolio and choose a call to sell.
When selling a covered call, note that you will be able to sell one call for every 100 shares of stock in your portfolio. In order to keep the strategy balanced, you can either buy more shares of the stock and sell more covered calls or sell less covered calls.

What Are the Risks and Rewards of Covered Calls?
Using a covered call strategy could serve specific purposes for income generation or risk management. As with any trading strategy, investors need to keep in mind that covered call gains (along with any other gains or losses realized by the strategy) are subject to capital gains taxes.
Here are several pros and cons of the covered call strategy to consider.
Potential Rewards
The benefits of utilizing covered calls include the potential to receive added income and offset downside risk.
• Investors can earn income by keeping the premiums they collect from selling the options contracts. Depending on how often they sell covered calls, this can lead to recurring income opportunities.
• Investors can determine an adequate selling price for the stocks they own and use that for the strike of the call option to be sold. If the option is exercised, an investor will realize their intended profit from the sale (as well as the premium).
• The premium the investor receives for the sold call will help offset a potential decline in a stock’s price. This provides limited downside protection, though losses can still occur.
• Covered calls may be permitted in certain IRA accounts, subject to account eligibility and approval requirements.
Potential Risks
There are also a few drawbacks to using a covered call strategy:
• Investors could forgo additional upside if a stock’s price rises, and continues to rise, above the strike price. This is an inherent trade-off of the strategy that was described above. Investors that sell covered calls must accept the obligation to sell the stock at the strike price if the buyer exercises the option.
• Since the sold call is covered by the stock, an investor would need to buy back the covered call option they sold before they may sell their stocks on the market. This limits the investor’s flexibility to respond to price movements. (Be aware that uncovered calls present too much risk in SoFi member portfolios and are not allowed.)
What Is the Best Market Environment for a Covered Call?
There is no single correct time to use a covered call strategy — as with any trading strategy, it depends on evaluating the market environment and weighing the potential risks vs. the rewards of the premium income that could be generated. When an investor is holding a long stock position that they are planning to keep long-term, this is one key consideration. In terms of stock sentiment, there are three cases where an investor might choose to write a covered call.
1. When they feel the stock price will remain neutral.
2. When they feel the stock price will rise some, but not dramatically.
3. When they feel the stock price will rise dramatically and they are comfortable with the capped gain at the strike price (plus the premium received) where they might sell the covered call.
4. When they feel the stock price might drop temporarily, but their long term outlook for the stock is positive or neutral. Since market outcomes are uncertain, investors should be ready and willing to accept the risk considerations outlined above.
As for why an investor might use covered calls? The goal is often to generate income from existing or purchased stock holdings. Another potential reason to use covered calls, for some investors, is to offset some risk using the premium received.
The Takeaway
A covered call may be attractive to some investors as it’s a way to generate additional income from a stock position. That said, as with all trading strategies, outcomes may vary based on market conditions and timing. There are no guarantees, and the strategy involves trade-offs between income potential and capped gains.

FAQ
Are covered calls free money?
Covered calls are not “free money.” They can generate income from the premiums received for the covered call, but they can also limit upside potential if the stock’s value increases significantly or the option is exercised when the price rises toward the strike.
Are covered calls profitable?
Covered calls can allow you to generate income, but results depend on the performance of the underlying stock and the terms of the option contract. If the option expires unexercised, the seller keeps the premium and the stock. The strategy tends to work best in neutral to moderately bullish markets, and profitability may depend on strike price and expiration the seller has chosen.
What happens when a covered call expires?
If a covered call expires without being exercised, nothing happens: the option just expires worthless. The seller keeps the premium received, which is a benefit of the strategy. Because an option is only that — an option to execute a trade at a predetermined price for a select period of time — if the stock price remains below the strike price the option will expire worthless.
If the stock price goes above the strike price, the option’s buyer will exercise the option. This obligates the option writer to sell their stock at the strike price. This technically happens the evening of expiration and on the following trading day, the covered call seller will have cash to replace the stock and the option position will no longer exist. With this cash, the trader can choose to re-buy the stock or use it the same as any settled cash position.
Can you make a living selling covered calls?
Living strictly off income from covered calls may be theoretically possible, but it would likely require a large portfolio to make it work. There are other factors to consider, too, like potential capital gains taxes and the fact that the market won’t always be in a favorable environment for the strategy to work.
What is the maximum profit on a covered call?
The maximum profit is the premium received plus any stock gains up to the strike price. Gains above the strike are capped, however, since the shares may be called away at (or potentially below) the strike if the option is exercised.
