Should You Sell a Covered Call?

Selling a covered call is a decision that balances income generation against potential upside. Before you sell, you should evaluate whether the premium justifies the cap on your stock's upside potential. This calculator helps you make that decision by showing exactly what you will earn in different scenarios and whether the risk-reward makes sense for your situation.

The most important question is: are you willing to sell your shares at the strike price? If the answer is yes, and the premium provides an attractive return, selling the covered call is usually a smart move. If you would be upset about losing your shares, choose a higher strike or wait for a better opportunity.

Sell Trade Calculation

Premium Income
Total Premium = Bid Price × Contracts × 100
Where:
Bid Price = The premium per share (use the bid, not the ask)
Contracts = Number of contracts
If-Called Return
Return = (Strike - Cost Basis + Premium) / Cost Basis × 100%
Where:
Strike = Call strike price
Cost Basis = Your stock purchase price
Premium = Premium per share

Calculation Steps

  2. 2Max profit = ($85 - $75 + $2.25) × 200 = $2,450
  3. 3Breakeven = $75 - $2.25 = $72.75
  4. 4Static return = $2.25 / $75 = 3.00%
  5. 5If-called return = $12.25 / $75 = 16.33%
  6. 6Annualized static = 3.00% × (365/30) = 36.50%
Result
Selling 2 contracts collects $450 in premium. If shares are called at $85, total return is 16.33%. The static return of 3% annualizes to 36.50%.

Sell-to-Open Order Execution Tips

How to Execute a Covered Call Sell Order

1
Use a Limit Order
Set your limit price at the midpoint between bid and ask. This often fills and gives you a better price than a market order.
2
Sell During Market Hours
Options spreads are tightest during regular market hours (9:30am-4:00pm ET). Avoid placing orders at market open when spreads are wide.
3
Verify the Order Type
Make sure you select 'Sell to Open' (not 'Buy to Open' or 'Sell to Close'). This creates a new short option position.
4
Confirm Contract Count
Double-check that the number of contracts matches the shares you own divided by 100. Selling more contracts than you have shares creates naked calls.
5
Review Before Submitting
Check the strike, expiration, premium, and total order value before clicking submit. Verify the credit amount matches your expectation.

Use the Bid Price for Calculations

When calculating your expected premium, always use the bid price, not the ask or mid price. The bid is what buyers are willing to pay, and it is the price you will receive on a market sell order. Using the mid-price may overestimate your actual premium income.

After You Sell: Managing the Position

  • Buy to close at 50% profit to free capital and reduce risk exposure
  • Let expire worthless if the option is nearly worthless with only a few days left
  • Roll to a new strike/expiration if you want to continue the strategy
  • Accept assignment if the stock rises above the strike and you are comfortable selling
  • Close for a loss if the stock drops sharply and you want to sell the shares

Frequently Asked Questions

To sell a covered call: (1) own at least 100 shares of the stock, (2) have options approval from your broker (Level 1), (3) select a strike price and expiration from the option chain, (4) place a 'Sell to Open' order for the call option. The premium is credited to your account immediately upon execution.
