What is a Covered Call?
Updated 24 October 2026 · by Theo Chen
A Covered Call is an income strategy on shares you already own. For every 100 shares you hold, you sell one Call option — usually at a strike above the current price — and collect a premium up front. In return you agree to sell those shares at the strike if the stock rises above it.

A Covered Call has two pieces:
- 100 shares you own (per Call contract).
- One short Call, usually with a strike above the current price. The premium is yours immediately; in exchange you may have to sell your shares at the strike.
If the stock stays below the strike, the Call expires worthless, you keep the premium and the shares, and you can sell another Call next month. If the stock finishes above the strike, your shares are called away at that price — still a profit, just capped. It is "covered" because you own the shares, so there is no open-ended risk like a Naked Call.
Max profit, breakeven and downside
- Max profit = (strike − cost basis + premium) × 100, reached if the shares are called away at the strike.
- Breakeven = cost basis − premium. The premium is a small cushion below your purchase price.
- Downside = you still own the shares, so a fall costs you just as it would holding them, softened only by the premium. A Covered Call is income, not a hedge.
A worked example
You own 100 shares bought at $100 and sell the $105 Call for $2.00. If the stock finishes below $105, you keep the $200 premium and your shares — a 2% return for the month on top of whatever the stock did. If it finishes above $105, your shares are called away at $105: your profit is (105 − 100 + 2) × 100 = $700, but you miss anything above $105. Your breakeven is $98 — the premium cushions the first $2 of any decline.
Own 100 shares at $100 and sell the $105 Call (red). Profit is capped at $700 if the shares are called away above $105; breakeven $98. You still own the shares, so the downside is the stock's.
What did the Call actually add? Our SPY exit-rule test
Premium collected is not profit earned. Before calling a Covered Call income, separate what the shares earned from what selling the Call added. Our OptionsDX SPY archive test isolates the short Call overlay: these results exclude share gains, losses and dividends. A negative overlay result is a cost of selling the upside; it does not mean the combined Covered Call lost money.
The study window runs from 2010-01-05 to 2023-12-15. This arm retained 164 monthly cycles, selling a Call near 0.30 delta with a target of 45 days to expiration (DTE). Each row uses the same entries and a different exit. Results are per short Call contract, before fees.
| Exit rule | Winning cycles (mid) | Average P/L (mid) | Average P/L (ask close) | Worst cycle (mid) | Average days held |
|---|---|---|---|---|---|
| Hold to expiration | 62.2% | -$84.50 | -$84.50 | -$3,319 | 45.0 |
| Take 25% of opening credit | 82.9% | -$32.63 | -$33.60 | -$3,319 | 17.5 |
| Take 50% of opening credit | 75.6% | -$46.54 | -$47.30 | -$3,319 | 23.4 |
| Close at 21 DTE | 53.7% | -$48.30 | -$51.09 | -$2,080 | 24.2 |
| Take 50% of opening credit or Close at 21 DTE | 66.5% | -$25.40 | -$28.09 | -$2,080 | 16.3 |
Against holding, the take 50% of opening credit rule produced no change in the magnitude of the worst overlay loss; the close at 21 DTE rule produced a 37.3% reduction. A profit target is an instruction for a winning Call, not a stop on a losing one. Closing the Call also leaves the shares exposed to a fall.
Entry credits use quote midpoints. The ask-close column buys the Call back at the ask on the same midpoint-triggered exit date; holding settles at intrinsic value. Targets are checked at daily closes, with no new Call sold after an early exit. This is an overlay comparison, not a compounded portfolio return or an assignment-and-dividend simulation.

Use the Covered Call Calculator to check your combined shares-and-Call payoff. Then use this table to question the exit rule: keeping the premium, buying back the Call and keeping the stock are different decisions.
When a Covered Call makes sense
Sell Covered Calls on shares you are happy to hold and willing to part with at a higher price, in a flat-to-mildly-bullish market. You give up the big rally above the strike for steady income. If you do not own the shares yet but would like to, selling a Cash-Secured Put is the mirror-image entry — and running the two in sequence is the Wheel Strategy.
The bottom line
A Covered Call trades the upside above your strike for premium today - it is income on shares you would happily sell at that strike, not protection against a fall, since the thin premium barely cushions a large decline.
Frequently asked questions
What is a Covered Call?
A Covered Call is an income strategy on stock you already own. For every 100 shares you hold, you sell one Call option, usually with a strike above the current price, and collect a premium up front. It is "covered" because you own the shares that would be delivered if the Call is exercised — so the position carries no open-ended risk, just a capped upside.
How much can you make selling a Covered Call?
The premium you collect is yours to keep no matter what. If the stock stays below the strike at expiration, you keep the shares and the premium, but your combined profit also reflects the change in the share price. If it rises above the strike, your shares are sold (called away) at the strike, so your maximum profit is the strike minus your cost basis, plus the premium: (strike − cost basis + premium) × 100 per contract.
What is the breakeven and downside of a Covered Call?
Breakeven is your cost basis minus the premium you collected — the premium gives you a small cushion below your purchase price. Below that, you lose money on the shares just as you would holding them outright, only softened by the premium. A Covered Call reduces your cost basis; it does not protect against a large fall, so it is not a hedge.
What happens when a Covered Call is assigned?
If the stock is above the strike at expiration, the Call is exercised and your 100 shares are sold at the strike price. You keep the premium and the gain up to the strike, but you miss any rise beyond it. Assignment is a normal, planned outcome — not a failure. Many traders then sell a Cash-Secured Put to buy the shares back, which is the Wheel Strategy.
When should you sell a Covered Call?
Covered Calls suit shares you are happy to hold and are willing to sell at a higher price, in a flat-to-mildly-bullish market. You give up the big upside above the strike in exchange for steady premium income. They are less attractive when you expect a sharp rally (you would cap it) or a sharp fall (the premium is thin protection).
