What Is a Covered Call?

A covered call is one of the most popular options trading strategies used by investors who own shares of a stock and want to generate additional income. In this strategy, you sell (write) a call option against shares you already hold, collecting the option premium as income. The strategy is called "covered" because your stock ownership covers the obligation to deliver shares if the option buyer exercises the contract.

Covered calls are considered a conservative options strategy because you already own the underlying shares. This makes them suitable for investors who have a neutral to moderately bullish outlook on a stock and want to generate income while they hold their position.

Key Concept

When you sell a covered call, you give someone else the right to buy your shares at the strike price before the expiration date. In exchange, you receive the option premium as immediate income.

How to Calculate Covered Call Returns

Understanding how to calculate covered call returns is essential for evaluating whether a particular covered call trade is worth pursuing. There are several key metrics you need to calculate: maximum profit, breakeven price, static return, and if-called return.

Maximum Profit Formula
Max Profit = (Strike Price - Purchase Price + Premium) × 100 × Contracts
Where:
Strike Price = The option's strike price
Purchase Price = Your cost basis per share
Premium = Premium received per share
Contracts = Number of option contracts (each = 100 shares)
Breakeven Price Formula
Breakeven = Purchase Price - Premium Received
Where:
Purchase Price = Price paid per share
Premium Received = Option premium collected per share
Static Return Formula
Static Return = (Premium / Purchase Price) × 100%
Where:
Premium = Premium received per share
Purchase Price = Price paid per share
Covered Call Calculation Example

Calculation Steps
  1. 1Total premium income = $3.50 × 100 shares = $350
  2. 2Capital gain if called = ($105 - $98) × 100 = $700
  3. 3Maximum profit = $350 + $700 = $1,050
  4. 4Maximum return = $1,050 / ($98 × 100) = 10.71%
  5. 5Breakeven price = $98 - $3.50 = $94.50
  6. 6Downside protection = $3.50 / $100 = 3.50%
Result
Maximum profit: $1,050 (10.71% return). Your breakeven is $94.50, with 3.50% downside protection from the premium.

When to Use a Covered Call Strategy

Covered calls work best in specific market conditions and when you have the right investment objectives. Understanding when to use this strategy can significantly improve your results.

  • You have a neutral to slightly bullish outlook on the stock
  • You want to generate income from shares you already own
  • You are willing to sell your shares at the strike price if the option is exercised
  • You want to reduce your cost basis over time through premium collection
  • You are looking for a lower-risk way to begin options trading
  • The stock has moderate implied volatility (higher premiums without excessive risk)

Covered Call vs. Other Options Strategies

The covered call is often compared to other income-generating strategies. Unlike a naked call (which carries unlimited risk), a covered call has defined risk since you own the underlying shares. Compared to a cash-secured put, a covered call is used when you already own shares, while a cash-secured put is used when you want to buy shares at a discount.

The poor man's covered call (PMCC) is a variation that uses a deep-in-the-money LEAPS option instead of shares, requiring significantly less capital. However, it also has different risk characteristics and may not be suitable for all investors.

Tips for Successful Covered Call Writing

Best Practices for Covered Calls

1
Choose the Right Strike Price
Select a strike price that balances premium income with upside potential. Out-of-the-money calls give you more upside but lower premiums, while at-the-money calls generate higher premiums but cap your gains sooner.
2
Consider Expiration Date
Options with 30-45 days to expiration often provide the best balance of premium income and time decay. Shorter expirations decay faster but offer less premium per day.
3
Monitor Implied Volatility
Higher implied volatility means higher premiums. Selling calls when IV is elevated can significantly increase your income. Avoid selling calls when IV is unusually low.
4
Watch for Earnings and Dividends
Be aware of upcoming earnings announcements and ex-dividend dates. These events can cause sudden price movements and early assignment. Some traders avoid writing calls through earnings.
5
Have an Exit Plan
Decide in advance what you will do if the stock moves significantly in either direction. You can buy back the call to close the position, roll it to a different strike or expiration, or let it expire.

Tax Implications of Covered Calls

In the United States, covered call premiums are generally taxed as short-term capital gains, regardless of how long you have held the underlying stock. If the call expires worthless, the premium is recognized as a short-term gain in the year of expiration. If the option is exercised, the premium is added to the sale price of the shares, which may affect whether your stock gain is short-term or long-term.

Tax Warning

Writing in-the-money covered calls can suspend the holding period for long-term capital gains treatment on your stock. Always consult a qualified tax professional for advice specific to your situation.

Frequently Asked Questions

The maximum profit on a covered call is limited to the premium received plus any capital appreciation from your purchase price up to the strike price. If the stock rises above the strike price, your profit is capped because the shares will be called away at the strike price. For example, if you bought stock at $98, sold a $105 call for $3.50, your maximum profit is ($105 - $98 + $3.50) × 100 = $1,050 per contract.
