What Is a Covered Call?
A covered call is one of the most popular options strategies for income-oriented investors. It involves two components: you own 100 shares of a stock (the 'covered' part) and you sell one call option contract against those shares (the 'call' part). By selling the call, you receive a premium upfront. In exchange, you accept the obligation to sell your shares at the strike price if the option is exercised.
The covered call is considered a conservative, income-generating strategy. You are not making a new directional bet \u2014 you already own the stock. Selling the call simply monetizes the expectation that the stock will not rise dramatically in the near term. You collect the premium as income, which enhances your total return on the stock position.
The trade-off is that you cap your upside. If the stock rallies past the strike price, your shares will be called away and you forgo further gains. In exchange for giving up that upside, you get immediate income in the form of the premium. For investors who plan to hold a stock long-term anyway, selling covered calls is a way to generate extra yield on an existing position.
How to Use This Calculator
The calculator takes four inputs and produces a complete payoff analysis for your covered call.
Stock Purchase Price
Enter the price at which you purchased (or plan to purchase) the stock. This is your cost basis and is used to calculate your total profit or loss on the combined position. If you already own the shares, use your actual cost basis. If you are considering a new position, use the current market price.
Current Stock Price
Enter the current market price of the stock. This is used to evaluate how far out of the money the call is and to estimate the realistic premium you might receive. If you are planning a trade, use the current price. If you already have the position, use today's price to evaluate whether to sell a new call.
Strike Price and Premium
Enter the strike price of the call you plan to sell and the premium you expect to receive. The strike determines the level at which your shares can be called away. The premium is the per-share income you collect. A higher strike means less premium but more upside potential. A lower strike means more premium but less room for the stock to rise before assignment.
Reading the Output
The calculator shows your maximum profit (stock gain plus premium), maximum loss (stock loss minus premium), and breakeven price (stock purchase price minus premium). It also shows the return on capital and annualized return if the call expires worthless.
Formula
The key formulas for a covered call are:
Max Profit = (Strike Price \u2212 Stock Purchase Price) + Premium Received
This occurs when the stock closes at or above the strike price at expiration. Your shares are called away at the strike price, and you keep the premium.
Max Loss = Stock Purchase Price \u2212 Premium Received
This occurs if the stock goes to zero. The premium provides a small cushion but does not meaningfully protect against severe losses.
Breakeven = Stock Purchase Price \u2212 Premium Received
Below this price, you have a net loss on the combined position.
Return on Capital = Premium Received / Stock Purchase Price \u00d7 100
This is the return you earn if the call expires worthless and you retain your shares. To annualize, multiply by (365 / days to expiration).
Examples
Example 1: Covered Call on MSFT
You own 100 shares of MSFT purchased at $400. The current price is $410. You sell a 30-day call with a $420 strike for $5.00 per share ($500 premium). Your maximum profit is ($420 \u2212 $400) + $5 = $25 per share, or $2,500 total. Your breakeven is $400 \u2212 $5 = $395. If MSFT stays below $420 at expiration, the call expires worthless, you keep your shares, and you have earned $500 in premium income. Your return on capital is $500 / $40,000 = 1.25% for 30 days, or approximately 15.2% annualized.
Example 2: Covered Call on AAPL
You own 100 shares of AAPL purchased at $150. You sell a 45-day call with a $160 strike for $3.50 ($350 premium). Your max profit is ($160 \u2212 $150) + $3.50 = $13.50 per share, or $1,350 total. Your breakeven is $150 \u2212 $3.50 = $146.50. If AAPL closes at $165 at expiration, the call is exercised and your shares are sold at $160. You miss the extra $5 of upside above $160, but you have already collected the $350 premium. Your total return is ($160 \u2212 $150) \u00d7 100 + $350 = $1,350.
Example 3: Rolling a Covered Call
Two weeks after selling the MSFT $420 call, MSFT drops to $405. The $420 call is now worth only $1.00 (down from $5.00). You can buy it back for $1.00 ($100 cost) and sell a new call with a $415 strike for $3.00. Your net credit is $2.00, bringing your total premium collected to $500 + $200 = $700. This is called rolling and is a common technique for managing covered calls when the stock moves against your position.
Tips
Sell Covered Calls When IV Is High
Higher implied volatility means higher option premiums. Selling covered calls when IV is elevated (for example, before earnings or during market turbulence) generates more income per trade. Check the implied volatility rank or percentile of the stock before deciding whether to sell. If IV is in the top 30% of its one-year range, it is generally a good time to sell.
Choose Strikes Based on Your Outlook
If you are bullish and want to keep the stock, choose an out-of-the-money strike (above the current price). You collect less premium but allow room for appreciation. If you are neutral and are happy to sell the stock, choose an at-the-money strike for maximum premium. The best strike depends on whether you prioritize income or upside participation.
Consider Dividends
If the stock pays a dividend, factor it into your total return calculation. A covered call on a 3% dividend stock with an additional 1% premium yields approximately 4% for the period. However, be aware that call assignment can happen before the ex-dividend date, causing you to miss the dividend. Some traders avoid selling calls through ex-dividend dates to prevent this.
Don't Sell Covered Calls on Stocks You Don't Want to Sell
A common mistake is selling covered calls on stocks you would be upset to lose. If you own a high-conviction growth stock that you believe will double, selling a covered call caps your upside for a small premium. Only sell covered calls on stocks you are comfortable parting with at the strike price. If assignment would cause you regret, choose a higher strike or skip the trade.
FAQ
What is a covered call?
A covered call is an options strategy where you own (or buy) 100 shares of a stock and simultaneously sell one call option against those shares. The call option gives someone else the right to buy your shares at the strike price. In exchange for selling the call, you receive a premium. The premium is yours to keep no matter what happens. The covered call is one of the most popular income-generating options strategies because it is straightforward and provides immediate cash flow.
When should I use a covered call?
Covered calls work best in neutral to slightly bullish markets. If you own a stock and believe it will stay relatively flat or rise modestly, selling a covered call lets you earn income on a position you already hold. It is also useful when you want to reduce your effective cost basis on a stock. The strategy underperforms in strong bull markets (because the call caps your upside) and in bear markets (because the small premium does not offset the stock decline).
What is the maximum profit on a covered call?
The maximum profit is the premium received plus the gain from the stock rising to the strike price. Formula: Max Profit = (Strike Price − Stock Purchase Price) + Premium Received. You achieve this maximum if the stock closes at or above the strike price at expiration and the call is assigned. Your shares are called away at the strike price, and you keep the premium on top of the stock gain.
What is the maximum loss on a covered call?
The maximum loss is the stock purchase price minus the premium received. This occurs if the stock goes to zero. In practice, the covered call only reduces your loss by the amount of the premium — it does not provide meaningful downside protection. If you need downside protection, consider a collar strategy (buying a protective put in addition to the covered call).
What is the breakeven for a covered call?
The breakeven price is your stock purchase price minus the premium received. For example, if you bought the stock at $50 and received a $2 premium, your breakeven is $48. Below $48, you have a net loss on the combined position even though the call expired worthless, because the stock loss exceeds the premium collected.
Should I sell covered calls every month?
Many investors sell covered calls monthly or weekly to generate recurring income. This is called a covered call rotation strategy. The approach works well in flat or range-bound markets. However, in strong trending markets (either up or down), you may be better off skipping a cycle. Selling calls during an uptrend means capping your gains; selling during a downtrend means collecting small premiums while the stock falls. Be selective about when you sell.
What strike should I choose for a covered call?
The strike determines the trade-off between income and upside potential. An at-the-money call (strike near the current stock price) generates the most premium but caps your upside immediately. An out-of-the-money call (strike above the current price) generates less premium but allows some upside before the shares are called away. The choice depends on whether you prioritize income (closer to ATM) or growth (further OTM).
Does a covered call protect against losses?
Only slightly. The premium received provides a small cushion — if you collect $2 per share, your breakeven drops by $2. But this is not meaningful protection in a real downturn. If you need downside protection, the covered call alone is not sufficient. Consider pairing it with a protective put (creating a collar) or using a different strategy entirely.
What happens if the stock is called away?
If the stock closes above the strike price at expiration, your shares will be called away (sold) at the strike price. You keep the premium and the gain from the stock purchase price to the strike price. You no longer own the shares. If you want to continue holding the stock, you can buy it back at the market price, but this creates a new position at a higher cost basis and may trigger a wash sale for tax purposes.
Are covered calls suitable for retirement accounts?
Yes, covered calls are often used in retirement accounts like IRAs because they generate income without requiring margin (since you own the underlying shares). However, some brokers have restrictions on options strategies in retirement accounts, so check with your broker. The strategy is also popular with dividend investors who want to enhance yield on their existing stock holdings.
