How Selling Covered Calls Works

Selling covered calls means you are the option seller (writer) collecting premium from option buyers. When you sell a call option against shares you own, you receive cash immediately. In exchange, you agree to sell your shares at the strike price if the buyer exercises the option before expiration. This transaction creates income from an asset you already hold, much like collecting rent on property you own.

The strategy is called 'selling to open' because you are opening a new short option position. If the stock stays below the strike price at expiration, the option expires worthless, and you keep the premium plus your shares. If the stock rises above the strike, your shares are called away at the strike price, and your total return includes both the premium and any capital gain.

Calculating Your Selling Returns

Premium Yield
Premium Yield = (Premium per Share / Stock Price) × 100%
Where:
Premium per Share = Cash received per share from selling the call
Stock Price = Current market price
Annualized Selling Return
Annualized Return = (Premium / Purchase Price) × (365 / DTE) × 100%
Where:
Premium = Premium per share
Purchase Price = Your cost basis
DTE = Days to expiration
Selling Covered Calls Example
Given
Stock Price
$175
Purchase Price
$170
Strike Price
$180
Premium
$4.50
DTE
30 days
Contracts
2 (200 shares)
Calculation Steps
  1. 1Total premium collected = $4.50 × 200 = $900
  2. 2Static return = $4.50 / $170 = 2.65%
  3. 3Annualized static return = 2.65% × (365/30) = 32.21%
  4. 4If-called return = ($180 - $170 + $4.50) / $170 = 8.53%
  5. 5Annualized if-called return = 8.53% × (365/30) = 103.78%
  6. 6Breakeven price = $170 - $4.50 = $165.50
  7. 7Maximum profit = ($180 - $170 + $4.50) × 200 = $2,900
Result
Selling 2 covered call contracts generates $900 in premium with a 2.65% static return (32.21% annualized). If shares are called away at $180, total return is 8.53%.

Practical Guide to Selling Covered Calls

How to Sell Your First Covered Call

1
Get Options Approval
Apply for Level 1 options trading at your brokerage. Covered calls require the lowest approval level. Most applications are approved within 1-2 business days.
2
Choose a Stock You Own
Select a stock from your portfolio that you would be comfortable selling at a profit. You need at least 100 shares per contract.
3
Open the Option Chain
In your broker's platform, navigate to the option chain for your stock. Look at the monthly expiration 30-45 days out.
4
Select Your Strike Price
Choose a strike 3-7% above the current stock price for a standard OTM covered call. Check the bid price - this is the premium you will receive.
5
Place a Sell-to-Open Order
Select 'Sell to Open' for the call option. Set a limit order at the mid-price between bid and ask for potentially better execution.
6
Monitor and Manage
Set alerts for the stock approaching the strike price. Consider buying back the call at 50-80% of maximum profit to free capital for the next trade.

Selling Frequency: Weekly vs. Monthly vs. Quarterly

Selling Frequency Comparison ($175 Stock, 2 Contracts)
FrequencyDTEPremium/CycleAnnual PremiumAnnualized Return
Weekly7 days$130$6,76019.60%
Biweekly14 days$210$5,46015.83%
Monthly30 days$900$10,80031.32%
45-Day45 days$1,200$9,73328.22%
Quarterly90 days$1,800$7,20020.87%

Monthly selling typically produces the highest annualized returns due to optimal theta decay. Weekly selling generates frequent income but lower total premium due to less absolute time value per cycle. Quarterly selling requires less management but leaves money on the table by not capturing the rapid theta decay in the final 30 days.

Frequently Asked Questions

For most long-term stock holders, selling covered calls is worth it. It generates 12-30% additional annual income on top of dividends, reduces your effective cost basis, and provides partial downside protection. The trade-off is capped upside during strong rallies. If you are comfortable with that trade-off, the strategy adds significant value.
