How to Sell Covered Calls: A Complete Beginner's Guide

What Is a Covered Call?

A covered call is one of the safest options strategies available to retail investors. You sell a call option on shares you already own, collecting premium income upfront. Think of it like renting out a room in a house you own — you keep the house, and you collect rent.

The "covered" part means you own the underlying shares. This limits your risk compared to selling "naked" calls, which is far riskier. With covered calls, the worst-case scenario is selling your shares at a profit (the strike price) and missing out on further upside.

Step 1: Own at Least 100 Shares

Each options contract covers 100 shares. To sell one covered call, you need to own at least 100 shares of the stock. This works best with blue-chip stocks you plan to hold long-term — companies like Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), or Nvidia (NVDA).

If you own 200 shares, you can sell 2 contracts. 500 shares = 5 contracts. The math scales linearly.

Step 2: Choose Your Strike Price

The strike price is the price at which you agree to sell your shares if the option is exercised. For covered calls, you want a strike price above the current stock price (out of the money, or OTM).

A good rule of thumb for beginners: choose a strike 5-10% above the current stock price. This gives you room for the stock to appreciate while still collecting a decent premium. For example, if Apple is trading at $230, consider strikes between $240 and $255.

How to Pick the Right Strike

Look at the delta of each strike. Delta tells you the approximate probability of the option expiring in the money (being exercised). A delta of 0.20 means roughly a 20% chance of assignment — that's what we recommend for conservative income strategies.

Higher delta (0.30-0.40) = more premium, but higher chance of losing your shares. Lower delta (0.05-0.15) = less premium, but very safe.

Step 3: Select Your Expiration Date

Covered call sellers earn money from time decay (theta). Options lose value as they approach expiration, and as a seller, that decay works in your favor.

The sweet spot for most covered call strategies is 30-45 days to expiration (DTE). This range offers the best balance of:

• Enough premium to make the trade worthwhile • Fast enough time decay to capture most of the value • Short enough to adjust if market conditions change

Weekly options (7 DTE) have low premiums per trade. 90-day options tie up your shares too long. Stick with 30-45 DTE unless you have a specific reason not to.

Step 4: Place the Sell-to-Open Order

In your brokerage account, navigate to the options chain for your stock. Select the expiration date, then find your desired strike price. Choose "Sell to Open" for a call option.

Always use limit orders, not market orders. Set your limit at the midpoint between the bid and ask prices, or slightly below the ask. This ensures you get a fair price.

The premium will appear in your account immediately after the order fills.

Step 5: Manage and Repeat

After selling the call, you have three possible outcomes:

1. Stock stays below the strike: The option expires worthless. You keep your shares and the premium. Sell another call.

2. Stock rises above the strike: Your shares get "called away" at the strike price. You keep the premium plus any gains up to the strike. Buy back in and start over, or move to a new stock.

3. Stock drops significantly: You keep the premium, which partially offsets the loss. The premium provides a buffer that buy-and-hold investors don't have.

Most experienced covered call traders roll their positions — closing the current call and opening a new one with a later expiration — to maintain continuous income.

How Much Can You Earn?

Conservative covered call strategies (10-20 delta, 30-45 DTE) typically generate 1-3% per month on your stock position, or 12-36% annualized. Actual returns vary based on:

• Stock price and volatility • Strike price selection • Market conditions • How often you trade

For example, selling a monthly covered call on $10,000 worth of stock might generate $100-$300 per month. Over a year, that's $1,200-$3,600 in additional income from a stock you were holding anyway.

A covered call screener like Covered Call Pro finds the highest premium-per-day opportunities across 50+ stocks daily, so you always know the best trade available.

Common Mistakes to Avoid

1. Selling calls on stocks you want to sell: Only sell covered calls on stocks you're happy holding long-term.

2. Chasing ultra-high premiums: Sky-high premiums usually mean the stock is extremely volatile. Stick to moderate-IV stocks.

3. Selling before earnings: Stocks can gap 10-20% on earnings. Either avoid selling calls over earnings dates, or use it as a deliberate strategy.

4. Forgetting about dividends: If your covered call is deep in the money near an ex-dividend date, you might get assigned early. Check the calendar.

5. Not having a plan: Decide in advance what you'll do if the stock moves up, down, or sideways.
