A covered call is one of the most conservative options strategies — it generates income from stocks you already own without buying anything new. Here is exactly how it works, what you earn, and what can go wrong.
What Is a Covered Call?
When you sell a covered call, you give another investor the right — but not the obligation — to buy 100 shares of your stock at a specific price (the strike price) before a set date (the expiration date). In exchange, they pay you a premium upfront.
The call is “covered” because you already own the shares. If the buyer exercises the option, you deliver your shares at the strike price. You keep the premium either way.
Three possible outcomes at expiration:
- Stock stays below strike → option expires worthless, you keep the premium + your shares
- Stock ends exactly at strike → typically still expires worthless; you keep premium + shares
- Stock rises above strike → shares get called away at the strike price; you keep the premium but miss gains above strike
How Much Can You Earn?
Premiums vary by stock, volatility, strike price, and time to expiration. The further the strike is from the current price (out of the money), the lower the premium — but the more room the stock has to rise before you lose shares.
Covered Call Premium Examples (100 shares, 30-day expiration)
| Stock Price | Strike Price | Out of Money % | Typical Monthly Premium | Annualized Yield |
|---|---|---|---|---|
| $50 | $52 | 4% out | $0.40–$0.70 ($40–$70) | 9.6%–16.8% |
| $100 | $105 | 5% out | $0.80–$1.50 ($80–$150) | 9.6%–18.0% |
| $100 | $110 | 10% out | $0.30–$0.70 ($30–$70) | 3.6%–8.4% |
| $200 | $210 | 5% out | $1.80–$3.50 ($180–$350) | 10.8%–21.0% |
| $50 (high-vol tech) | $53 | 6% out | $1.00–$2.00 ($100–$200) | 24%–48% |
Premiums are illustrative ranges for moderate-volatility stocks. High-volatility stocks pay more; stable dividend stocks pay less.
Worked Example: $100 Stock, $105 Strike, $1.20 Premium
You own 100 shares of XYZ Corp at $100 each. You sell one call option:
- Strike price: $105
- Expiration: 30 days
- Premium received: $1.20 per share × 100 = $120 cash upfront
Scenario A — stock closes at $102 at expiration: You keep the $120 premium. Your shares are worth $102 each. Total position value: $10,320 ($120 premium + $10,200 in shares).
Scenario B — stock closes at $108 at expiration: Your shares get called away at $105. You receive $10,500 + $120 premium = $10,620 total. But if you’d just held the shares they’d be worth $10,800. You missed $180 per 100 shares in upside.
Scenario C — stock falls to $90 at expiration: Option expires worthless; you keep $120. Shares are now worth $9,000. The $120 premium partially offsets the decline — your position is worth $9,120 instead of $9,000.
When Covered Calls Make Sense
Covered calls work best when:
- You expect the stock to stay flat or rise slowly
- You are willing to sell the shares at the strike price
- You want to generate income while waiting for a better exit price
They work poorly when:
- The stock is in a strong uptrend — you cap your gains
- You don’t want to sell the shares under any circumstances
Return Scenarios: Hold vs. Covered Call (100 shares at $100)
| Stock Outcome | Hold Shares | Sell $105 Call for $120 | Covered Call Advantage |
|---|---|---|---|
| Stock drops to $80 | −$2,000 | −$1,880 (premium softens loss) | +$120 |
| Stock stays at $100 | $0 | +$120 | +$120 |
| Stock rises to $105 | +$500 | +$620 ($500 gain + $120 prem) | +$120 |
| Stock rises to $110 | +$1,000 | +$620 (capped at $105 + prem) | −$380 |
| Stock rises to $120 | +$2,000 | +$620 (capped at $105 + prem) | −$1,380 |
The covered call wins in all flat-to-modest scenarios. The breakeven is $105 + $1.20 = $106.20 — you only regret selling the call if the stock exceeds $106.20.
How to Sell a Covered Call
- Own at least 100 shares of the stock (one contract = 100 shares)
- Open your broker’s options interface — you’ll need options trading approval (usually Level 1 or Level 2)
- Select “Sell to Open” a call option on your stock
- Choose strike price and expiration — most traders use 30–45 days out and 5–10% out of the money
- Enter the order — you can use a limit order at the mid-price between bid and ask
- Collect premium — credited to your account immediately
Most major brokers (Fidelity, Schwab, TD Ameritrade/Schwab, Interactive Brokers) offer covered call trading. You need to enable options trading in your account settings.
Tax Treatment of Covered Calls
Covered call premiums are taxed differently depending on outcome:
| Outcome | Tax Treatment |
|---|---|
| Option expires worthless | Short-term capital gain in year received |
| Option bought back (closed early) | Short-term capital gain or loss |
| Option exercised (shares called away) | Premium added to stock sale proceeds; holding period determines LTCG vs. STCG |
| Qualified covered call | Special rules may preserve long-term holding period — see IRS Pub. 550 |
Important: Selling a call on shares you’ve held less than 1 year does not restart the holding period. But selling an “unqualified” covered call on shares you’ve held more than 1 year can affect long-term capital gain treatment. Consult IRS Publication 550 or a tax professional before selling calls on appreciated long-term positions.
The Covered Call Strategy (Monthly Income System)
Some investors run a systematic covered call program on a core stock holding:
| Month | Action | Premium Collected | Shares Status |
|---|---|---|---|
| January | Sell Feb $105 call | $120 | Own 100 shares |
| February | Call expires; sell Mar $106 call | $110 | Own 100 shares |
| March | Call expires; sell Apr $107 call | $105 | Own 100 shares |
| April | Stock jumps to $115; call exercised | $120 | Shares called away at $107 |
| Total 4 months | — | $455 | Exit at $107 + $455 = $10,755 |
Over 4 months, $455 was collected on a $10,000 position — a 4.55% return in 4 months, regardless of the stock’s modest appreciation.
Covered Calls vs. Other Income Strategies
| Strategy | Typical Yield | Risk | Requires |
|---|---|---|---|
| Covered call | 6%–18%/yr | Capped upside | 100+ shares of stock |
| Dividend stocks | 2%–5%/yr | Market risk | Capital |
| Bonds/CDs | 4%–5.5%/yr | Low | Capital |
| Cash-secured put | 6%–15%/yr | Owning stock at strike | Cash reserve |
| Rental real estate | 5%–8% cash-on-cash | Illiquidity, maintenance | Large capital, time |
Covered calls generate more income than dividends from the same shares, at the cost of limiting upside.
