In short: Covered calls explained: a covered call earns income on shares you already own. Here is how it works and what it gives up.
A covered call combines owning at least 100 shares of a stock with selling a call option against them.
How it works
You sell someone the right to buy your shares at a set price, the strike, before expiration. In exchange, you receive a payment called the premium right away.
The possible outcomes
If the stock stays below the strike, the option expires, and you keep the shares and the premium. If it rises above the strike, your shares may be sold at the strike price. You keep the premium, but you give up gains above that price.
Why people use it
To generate income from shares they plan to hold and to slightly soften small price drops.
The tradeoffs
- Your upside is capped.
- You still bear the loss if the stock falls a lot, only cushioned by the premium.
- Shares can be called away, which may create a tax event.
Learn before you try
Practice with a paper account and read your broker’s options approval requirements.
How a covered call works
You own at least 100 shares of a stock and sell a call option against them. You collect a premium right away. In return, you agree to sell your shares at the strike price if the buyer exercises the option before expiration. Example: you own 100 shares at $50, sell a $55 call for $1 per share and collect $100. If the stock stays below $55, you keep the shares and the $100. If it rises above $55, your shares may be sold at $55, and you miss gains beyond that.
The trade-off
Covered calls add some income and a small cushion against a drop, but they cap your upside. You still bear the full risk if the stock falls a lot.
When people use them
Investors who expect little movement or are happy to sell at the strike price. They are not a way to avoid risk.

Frequently asked questions
Can I lose money?

Worked Example With Real Numbers
Say you own 100 shares of a stock trading at $50, so your position is worth $5,000. You sell one call with a $55 strike that expires in about a month and collect a premium of $1.20 per share, which is $120 in total.
There are three simple outcomes at expiration.
- Stock ends at $52: the call expires worthless. You keep the shares and the $120. The shares gained $200, so the total is $320.
- Stock ends at $58: your shares are called away at $55. You receive $5,500 plus the $120, which is $5,620. You gave up the move from $55 to $58, which is $300 of upside you did not get.
- Stock ends at $44: the call expires worthless and you keep $120. The shares lost $600, so the net loss is $480. The premium softened the fall but did not stop it.
The Break Even Point
With a premium of $1.20, your effective cost drops from $50 to $48.80. As long as the stock stays above $48.80, you are ahead on the position compared with your original purchase. Below that, you are behind. This shows why the strategy gives limited cushion. The premium is a small buffer, not protection from a large decline.
Choosing a Strike and Date
A strike close to today’s price pays more premium but is more likely to be reached. A strike far above pays less but leaves more room for the shares to rise. Shorter expirations lose value faster, which is why some investors use weekly or monthly contracts. Longer ones pay more in total but tie up the shares longer. There is no best choice. It depends on what you are willing to give up.
Risks People Overlook
- Early assignment. The buyer can exercise before expiration, most often right before a dividend.
- Selling calls on a stock you would hate to lose, then feeling regret when it jumps.
- Choosing stocks only because they pay high premiums. High premium often means high risk.
- Taxes. A called away sale can create a taxable gain, and holding period rules may apply.
What to Do Next
Before trying this with real money, work out the three outcomes above for a stock you know, using made up numbers. Make sure you would be fine with each result. Then check what approval level your broker requires and practice in a paper account. The stock profit and loss calculator can help with the math, and the dividend income calculator is useful if you also care about dividend dates.

Questions people ask about covered calls
What does it mean to write a covered call?
You own at least 100 shares and sell someone the right to buy them at a set price, called the strike, by a set date. You receive a payment, called the premium, right away. The word covered means your shares back the obligation.
What is the main risk?
Your gain is capped. If the stock rises well above the strike, your shares may be sold at the strike price and you miss the extra gain. You also still carry the loss if the stock falls sharply. The premium only offsets a small part of that.
Do I need special approval to try this?
Yes. Brokers usually require options approval and ask about your experience. Many also offer paper trading accounts, where you can practice with pretend money first. Check the glossary for terms such as strike, premium and assignment, and read your broker’s options risk disclosure before you start.
Quick recap
A covered call trades some upside for a premium on shares you already own. It can add income, but it does not protect against large declines and it can create tax consequences if shares are called away. Practicing in a paper account first is a careful way to learn how it works.
