Own 100+ shares of a stock? A covered call lets you earn extra cash each month by selling someone the right to buy your shares at a higher price. Here is how it works, what you earn, and what you give up, explained step by step.
If you already own shares of a stock, there is a way to earn a little extra cash from them each month. It is called a covered call. It is one of the oldest and calmest option strategies, and in 2026 it has become popular again as people look for steady income in a choppy market.
This guide walks through the covered call step by step, in plain English. We will cover how it works, how much you might earn, what you give up, and the simple mistakes that trip up beginners. No hype, just the real picture.
What Is a Covered Call?
First, a quick word on options. An option is a contract that gives someone the right to buy or sell a stock at a set price by a set date. A call option is the right to buy a stock at an agreed price.
When you sell a call, you are the person on the other side of that deal. You are promising to sell your shares at the agreed price if the buyer asks. In return, they pay you cash right away. That cash is called the premium, and it is yours to keep no matter what happens next.
The word "covered" is the key. It means you already own the shares you are promising to sell. Because the shares are sitting in your account, you are covered. You are not borrowing anything or betting with money you do not have. That is what makes this strategy so much safer than most option trades.
One contract equals 100 shares
In the US, one option contract almost always covers 100 shares. So to sell one covered call, you need to own at least 100 shares of that stock. If you own 300 shares, you could sell up to three contracts. This is why covered calls suit people who already hold decent-sized positions, often inside a taxable account or, in some cases, an IRA that allows it.
A Simple Example
Let us use round numbers so the math is easy. Say you own 100 shares of a company trading at $50 a share. That position is worth $5,000.
You decide to sell one covered call with a strike price of $55 that expires in one month. The strike price is the price at which you have agreed to sell. For taking on that promise, a buyer pays you a premium of, say, $1.00 per share. Because one contract is 100 shares, you collect $100 in cash today.
Now three things can happen by the expiry date:
- The stock stays below $55. The buyer has no reason to pay $55 for shares they could get cheaper on the open market. The option expires worthless, you keep your 100 shares, and you keep the $100. You can then sell another call next month and do it again.
- The stock rises above $55. The buyer exercises their right. You must sell your 100 shares at $55, for $5,500. You still keep the $100 premium. Your shares were "called away", but you sold at a price you were happy with and pocketed extra income on top.
- The stock falls, say to $45. The option expires worthless and you keep the $100. That $100 softens the loss on your shares a little, but you are still down on the stock itself. A covered call is not real protection against a big drop.
How Much Can You Earn?
In our example, $100 on a $5,000 position is a 2% return in one month, just from the premium. Do not expect that every time. How much premium you collect depends on a few things:
- How far the strike is from the current price. A strike close to today's price pays more but is more likely to get your shares called away. A strike far above pays less but lets more of the upside stay yours.
- How long until expiry. More time means more premium, but also more time for things to change.
- How jumpy the stock is. Options on wild, fast-moving stocks pay fatter premiums because the buyer is paying for a bigger chance of a big move. In 2026, with speculation running hot and chip stocks swinging around, premiums on tech names have been generous, but so has the risk.
A realistic goal for many investors is roughly 0.5% to 2% of the position per month in premium. Small, but it adds up over a year, and it turns a stock that just sits there into one that pays you to hold it.
The Trade-Off: You Cap Your Upside
Here is the honest catch. When you sell a covered call, you give up the big win. If your $50 stock suddenly jumps to $70 on great news, you still have to sell it at $55. You made your premium and a modest gain, but you missed the rocket.
That is the deal. You are trading away the rare, huge upside in exchange for steady, reliable income. For a calm long-term holder, that is often a fair swap. For someone holding a stock they think could double, it is not.
A good habit is to only sell covered calls at a strike price where you would genuinely be happy to sell. If $55 is a price you would gladly take, then getting called away is not a loss, it is a plan working out. If you would be gutted to sell at $55, pick a higher strike or skip the trade.
Picking Your Strike and Expiry
Two choices shape every covered call: which strike price, and which expiry date.
Choosing the strike
Most beginners start with a strike a bit above the current price, often 3% to 7% higher. This "out-of-the-money" strike gives your stock some room to rise before it gets called away, while still paying a useful premium. It is a middle path between grabbing maximum income and keeping maximum upside.
Choosing the expiry
Selling calls that expire in about 30 to 45 days is a common sweet spot. Options lose value fastest as expiry nears, and that decay works in your favor as the seller. Very short-dated options, like the popular one-day contracts you may have read about, move fast and demand constant attention, so they are usually not the place for a beginner running covered calls.
To pick a smart strike, many traders look at the expected move, which is the rough range the market thinks a stock will trade in by expiry. Selling a call outside that expected range lowers the odds your shares get called away. Learning using the expected move to plan trades is one of the most useful skills for this, and tools like TS Expected Move can plot those bands on your chart so you are not guessing.
Covered Calls in the 2026 Market
Why the renewed interest right now? As of mid-2026, the Federal Reserve, the US central bank, is holding interest rates high at 3.5% to 3.75% and hinting it may even raise them. That "higher for longer" stance keeps a lid on how fast stocks can run. The S&P 500, the main index of 500 big US companies, is near 7,500 and up around 9% for the year, but analysts warn speculation is at extreme levels and year-end targets are all over the place.
In a market that grinds sideways or rises slowly, covered calls shine. You are not counting on a big rally. You are collecting rent on shares you already own while the market chops around. If stocks scream higher, you will wish you had not sold the calls, but in a flat-to-slightly-up market, the extra income is welcome.
Common Mistakes to Avoid
- Selling calls on shares you love and never want to sell. If the stock takes off, you will be forced to hand it over. Only write calls on holdings you are truly willing to part with at the strike.
- Chasing fat premiums on risky stocks. A huge premium is the market warning you the stock could move violently. Big income often comes with big drops.
- Forgetting the downside. A covered call gives you a small cushion, not protection. If your stock crashes, the premium barely helps. Only hold stocks you would be comfortable owning through a rough patch.
- Ignoring taxes. Premiums and called-away shares can create taxable events. Keep simple records and, if in doubt, ask a tax professional.
- Panicking when a call goes against you. If the stock rises past your strike, that is not a disaster. You still made money. Let the trade play out instead of buying the option back in a fright at a loss.
Where Covered Calls Fit in a Bigger Plan
Covered calls are the friendly starting point for income options, but they are not the only one. The mirror-image strategy is to get paid to buy a stock you want, which you can read about in our guide to cash-secured puts as a calmer way to buy stocks in 2026. That approach lets you name a lower price you would happily pay and collect cash while you wait.
When you combine the two, selling puts to buy in and covered calls to earn income once you own the shares, you get a simple, repeatable cycle. That full loop is known as the wheel, and our breakdown of the wheel strategy for options income in 2026 shows how the pieces fit together for patient investors.
Start small and keep it boring
If you are new to this, start with a single contract on a stock you already own and understand well. Watch how the premium behaves, how time decay helps you, and how it feels when a call ends in or out of the money. One month of real experience teaches more than a stack of articles.
Covered calls will not make you rich overnight, and that is the point. They are a slow, steady way to squeeze a bit more out of stocks you already hold. Done with discipline, on shares you are happy to sell, at strikes you have thought through, they can turn a quiet portfolio into one that pays you a little every month.
