Quick Answer
To buy your first call option follow these steps:
- Choose a stock you believe may rise in price
- Check implied volatility to make sure options are not overpriced
- Select an expiration date — at least 30-45 days out for beginners
- Choose a strike price — at-the-money or slightly out-of-the-money
- Calculate the total cost and break-even price
- Place a buy-to-open limit order through your broker
Each options contract controls 100 shares. The total cost is the option premium multiplied by 100. The maximum loss is limited to the premium paid.
Key Takeaways
- A call option gives the right to buy a stock at a specific price before expiration
- The total cost of one contract equals the premium multiplied by 100
- Break-even at expiration equals the strike price plus the premium paid
- Choose expirations at least 30-45 days out to reduce time decay pressure
- At-the-money options offer the best balance of cost and responsiveness for beginners
- Always check implied volatility before buying — overpaying for IV is one of the most common beginner mistakes
- Most traders sell the option before expiration rather than exercising it
What Is a Call Option?
A call option is a contract that gives the buyer the right — but not the obligation — to buy a stock at a specific price before a certain expiration date.
If the stock price rises above the strike price the call option gains value. If the stock stays flat or falls the option loses value and may expire worthless.
Call options are used for three primary purposes:
Bullish speculation — profiting from an expected rise in a stock’s price with less capital than buying shares outright.
Leveraged exposure — controlling 100 shares of stock for a fraction of the cost of owning those shares directly.
Defined risk — the maximum possible loss is always capped at the premium paid regardless of what the stock does.
Example:
- Stock: $100
- Call strike price: $105
- Expiration: 30 days
- Premium: $2.50
- Total cost: $250
- Maximum loss: $250
If the stock rises to $115 before expiration the call option increases significantly in value. If the stock falls to $80 the maximum loss is still only the $250 premium — not the $2,000 loss a shareholder would experience.
This defined risk is one of the core advantages of buying call options versus owning stock outright.
What You Need Before You Start
Before placing your first call option trade make sure you have:
A brokerage account approved for options trading — most brokers require a brief application confirming you understand the risks. Approval is typically granted within one to three business days.
Enough capital for at least one contract — the minimum is one contract which costs the premium multiplied by 100. A $2.00 option costs $200 total.
Basic understanding of the options chain — the table in your broker platform showing all available strike prices and expiration dates for a stock. See the section below on how to read it.
A clear thesis — why do you believe this stock will rise and over what timeframe? A call option trade without a specific catalyst or price target is speculation without a plan.
How to Buy a Call Option — Step by Step
Step 1 — Choose a Stock
Start with stocks you already follow and understand. For your first call option trade focus on large, liquid stocks with active options markets.
Good candidates for first-time call option buyers:
| Stock | Ticker | Why It Works for Beginners |
|---|---|---|
| Apple | AAPL | Deep liquidity, tight spreads, predictable behavior |
| Nvidia | NVDA | High momentum, active options market |
| Amazon | AMZN | Liquid options, diversified business |
| Microsoft | MSFT | Stable large-cap, liquid options |
| Tesla | TSLA | High volatility, active market — more risk |
Avoid thinly traded small-cap stocks for your first trade. Wide bid-ask spreads on illiquid options can cost you 10-20% of your position value immediately on entry and exit.
Step 2 — Check Implied Volatility Before You Buy
This step is one most beginners skip entirely — and it is one of the most important.
Before buying a call option check the current implied volatility and IV rank for the stock. If IV rank is above 60 options are expensive relative to their historical norm. Buying in a high IV environment means paying inflated premiums that are more likely to deflate even if the stock moves in your favor.
| IV Rank | What It Means for Buyers |
|---|---|
| 0 – 30 | Favorable — options are relatively cheap |
| 30 – 50 | Neutral — acceptable conditions |
| 50 – 70 | Caution — options are getting expensive |
| 70 – 100 | Unfavorable — high risk of IV crush |
For your first call option trade target an IV rank below 40. This is not always possible but it significantly improves your odds of success by ensuring you are not overpaying for volatility expectations that may not materialize.
For a complete explanation see our guide on What Is Implied Volatility?
Step 3 — Choose an Expiration Date
Every options contract has an expiration date. After this date the contract ceases to exist.
Common expiration choices:
- Weekly options — expire each Friday. Cheapest but lose value extremely fast. Not recommended for beginners.
- Monthly options — expire on the third Friday of each month. The standard choice for most retail traders.
- Longer-term options (LEAPS) — expiration dates six months to two years out. More expensive but much less time pressure.
For your first call option choose an expiration at least 30-45 days out.
This gives the trade time to develop without facing the most aggressive phase of time decay. Options with less than 21 days remaining lose value rapidly even when the stock moves slightly in the right direction.
General guideline:
| Expiration | Time Decay Pressure | Best For |
|---|---|---|
| 7 days or fewer | Severe | Experienced traders only |
| 14-21 days | High | Active traders with a near-term catalyst |
| 30-45 days | Moderate | Beginners — recommended starting range |
| 60-90 days | Lower | Traders who want more time for the thesis to develop |
| 6+ months (LEAPS) | Minimal daily | Long-term directional trades |
Step 4 — Choose a Strike Price
The strike price is the price at which you have the right to buy the stock if you exercise the option. It determines how much the option costs and how much the stock needs to move for the trade to be profitable.
Strike prices are categorized as:
In-the-money (ITM) — strike price is below the current stock price for a call. More expensive but responds more directly to stock movement. Delta typically 0.60-0.90.
At-the-money (ATM) — strike price is at or near the current stock price. Balanced cost and responsiveness. Delta typically near 0.50.
Out-of-the-money (OTM) — strike price is above the current stock price. Cheaper but requires a larger stock move to become profitable. Delta typically 0.20-0.40.
Example with a stock at $100:
| Strike | Moneyness | Est. Premium | Delta | Stock Needs to Reach |
|---|---|---|---|---|
| $90 | Deep ITM | $12.00 | 0.88 | Already profitable |
| $95 | ITM | $7.50 | 0.72 | $95+ |
| $100 | ATM | $4.00 | 0.52 | $104+ (break-even) |
| $105 | OTM | $2.00 | 0.32 | $107+ (break-even) |
| $110 | Deep OTM | $0.80 | 0.16 | $110.80+ (break-even) |
For your first call option the at-the-money strike is the best starting point. It offers meaningful responsiveness to stock movement without requiring a large move to generate profit. Deep out-of-the-money options are cheap for a reason — they expire worthless far more often than beginners expect.
Step 5 — Calculate the Premium and Break-Even
Before placing any trade calculate two numbers:
Total cost = Premium × 100
Break-even price at expiration = Strike price + Premium paid
Example:
- Stock price: $100
- Call strike: $100 (ATM)
- Premium: $4.00
- Total cost: $400
- Break-even at expiration: $100 + $4 = $104
The stock needs to reach $104 by expiration for the trade to break even at expiration. Every dollar above $104 generates $100 of profit per contract.
This break-even calculation is non-negotiable before every trade. If the break-even price requires a move that seems unrealistic given the timeframe and the stock’s normal behavior the trade is not worth taking.
Step 6 — Place the Order
Once you have selected the contract navigate to the options chain in your broker platform and place a buy-to-open order.
Order details required:
- Ticker symbol
- Expiration date
- Strike price
- Number of contracts
- Order type — always use a limit order not a market order
Always use a limit order. Options have bid-ask spreads — the difference between what buyers will pay and what sellers will accept. A market order fills at the ask price which is always worse than the midpoint. A limit order set at the midpoint between bid and ask gives you a fair fill without overpaying.
After the order fills the contract appears in your portfolio as a long call position.
Full Call Option Trade Example
Here is a complete trade from start to finish:
Setup:
- Stock: Nvidia (NVDA)
- Current price: $450
- Thesis: expecting continued AI infrastructure spending to drive the stock higher over the next month
- IV rank: 38 — acceptable conditions for buying
Contract selection:
- Strike: $450 (ATM)
- Expiration: 35 days
- Premium: $12.00
- Total cost: $1,200
- Break-even at expiration: $462
Trade placed: Buy to open 1 NVDA $450 call expiring in 35 days at $12.00 limit
Possible outcomes at expiration:
| NVDA Price | Option Value | Profit/Loss |
|---|---|---|
| $420 | $0 | −$1,200 |
| $440 | $0 | −$1,200 |
| $450 | $0 | −$1,200 |
| $462 | $12 | $0 (break-even) |
| $470 | $20 | +$800 |
| $480 | $30 | +$1,800 |
| $500 | $50 | +$3,800 |
The maximum loss is $1,200 regardless of how far Nvidia falls. The profit potential is theoretically unlimited as the stock rises above the break-even price.
How to Read the Options Chain
The options chain is the table in your broker platform showing every available contract for a stock. Here is what each column means:
| Column | What It Shows |
|---|---|
| Expiration | The date the contract expires |
| Strike | The price at which you can buy the stock |
| Bid | The highest price a buyer will pay |
| Ask | The lowest price a seller will accept |
| Last | The most recent transaction price |
| Volume | Number of contracts traded today |
| Open Interest | Total number of active contracts |
| IV | Implied volatility for that specific contract |
| Delta | How much the option moves per $1 stock move |
| Theta | How much value the option loses per day |
When selecting a contract focus on strikes with open interest above 500 and a reasonable bid-ask spread. Wide spreads on low-volume contracts cost you money on both entry and exit.
What Happens After You Buy the Call Option
The Stock Rises
If the stock price increases the call option premium rises along with it. You have three choices:
Sell the option for a profit — the most common outcome. Most traders close positions before expiration by selling the contract back in the market. You capture the gain without exercising the option.
Hold for more upside — if your thesis remains intact and the stock has momentum you can hold the position. Be aware that time decay accelerates as expiration approaches.
Exercise the contract — converting the option into 100 shares at the strike price. This is rarely the best choice for short-term traders since selling the option captures both intrinsic and any remaining extrinsic value.
The Stock Stays Flat
If the stock does not move the option gradually loses value every day due to theta decay. A flat stock is a losing scenario for call option buyers — time is always working against you. This is why having a specific catalyst or timeframe in mind before buying is important.
The Stock Falls
If the stock declines the call option loses value. You can close the position early to recover whatever remaining value exists rather than watching it decay to zero. The maximum loss is always capped at the premium paid — you cannot lose more than your initial investment on a long call.
How to Close a Call Option Before Expiration
Most options trades are closed before expiration by selling the contract back in the market. This is called a sell-to-close order.
To close your position:
- Navigate to the open position in your broker platform
- Select the contract you want to close
- Place a sell-to-close order
- Use a limit order at the midpoint between bid and ask
- Once filled the position is closed and your profit or loss is realized
You do not need to hold an option until expiration. In fact most experienced traders close positions when they reach 50-75% of the maximum potential gain rather than holding for the last few percent. This avoids the rapid decay of the final stretch and frees up capital for the next trade.
Call Option Profit and Loss at Expiration
Here is a summary of how profit and loss work at expiration for a simple long call:
| Scenario | What Happens |
|---|---|
| Stock below strike | Option expires worthless — lose full premium |
| Stock at strike | Option expires worthless — lose full premium |
| Stock at break-even | Option worth exactly the premium — no gain no loss |
| Stock above break-even | Option profitable — gain increases with every dollar above break-even |
| Stock far above strike | Maximum gain — profit grows dollar for dollar with stock above break-even |
The key insight: the stock must rise above the break-even price — not just the strike price — for the trade to be profitable at expiration. Many beginners confuse strike price with break-even. They are not the same.
Common Mistakes Beginners Make Buying Call Options
Buying extremely cheap out-of-the-money options
Very cheap options are cheap because they require large fast moves to become profitable. A $0.50 option on a $100 stock needs the stock to move well above the strike price plus the premium just to break even. Most expire worthless. The low cost feels like limited risk but the probability of profit is very low.
Choosing expirations that are too short
Weekly options expire in days. Time decay in the final week before expiration is severe — the option can lose 20-30% of its value in a single session if the stock does not move. Beginners consistently underestimate how fast short-dated options decay. Start with 30-45 day expirations minimum.
Ignoring implied volatility before buying
Buying options when IV rank is above 60-70 means paying elevated premiums that are likely to deflate. Even a correct directional move can result in a loss if IV collapses faster than the stock moves. Always check IV rank before entering a call option position.
Not knowing the break-even price
Every call option has a break-even price — the strike plus the premium paid. Many beginners buy a call thinking they profit the moment the stock rises above the strike. That is incorrect. The stock must exceed the break-even price at expiration for the trade to be profitable. Calculate this number before every trade.
Letting losing options expire worthless
If a call option still has time value and the trade is clearly not working closing the position early recovers some of the premium paid. Holding a losing option to zero out of hope is one of the most common ways beginners turn a manageable loss into a total loss.
Using market orders instead of limit orders
Options bid-ask spreads can be $0.10-$0.50 wide or more on less liquid contracts. A market order fills at the ask — always the worst possible price. A limit order set at the midpoint saves money on every single trade. Never use a market order on options.
Which Broker Should You Use for Options Trading?
To buy call options you need a brokerage account that supports options trading and provides access to a clear options chain with Greeks displayed. Here are three platforms worth considering:
Webull — Commission-free options trading with a clean options chain that displays delta, IV, and other key metrics. A solid first platform for beginners who want to practice reading the chain and placing orders without paying high fees.

Frequently Asked Questions About Buying Call Options
How much money do you need to buy a call option?
The minimum cost is one contract — the premium multiplied by 100. A $2.00 option costs $200 total. A $10.00 option costs $1,000. Most beginner-friendly call options on liquid large-cap stocks cost between $200 and $800 per contract depending on the strike and expiration selected.
Do you need to own the stock to buy a call option?
No. Buying a call option does not require owning the underlying stock. You are purchasing the right to buy shares at the strike price — not the shares themselves.
What happens if my call option expires worthless?
If the stock is below the strike price at expiration the option expires worthless and you lose the full premium paid. This is the maximum possible loss on a long call — you cannot lose more than the premium regardless of how far the stock falls.
Can you sell a call option before expiration?
Yes. Most traders close positions before expiration by placing a sell-to-close order in the same options chain. You capture whatever value remains in the contract without waiting for expiration.
What is the break-even price for a call option?
Break-even at expiration equals the strike price plus the premium paid. A $100 strike call purchased for $4.00 breaks even at $104. The stock must exceed $104 at expiration for the trade to be profitable. This number must be calculated before every trade.
What is the difference between exercising and selling a call option?
Exercising a call option converts it into 100 shares of stock at the strike price. Selling a call option before expiration captures both intrinsic and remaining extrinsic value as cash. Most traders sell rather than exercise because exercising forfeits any remaining time value in the contract.
How do you know if a call option is fairly priced?
Check the implied volatility and IV rank for the stock. If IV rank is below 30-40 options are relatively cheap compared to historical norms — a favorable environment for buyers. If IV rank is above 60-70 options are expensive and the risk of IV crush is elevated. Always evaluate IV rank before buying any options contract.
What delta should I target for my first call option?
Most beginners target at-the-money calls with a delta near 0.50. This provides meaningful responsiveness to stock movement — the option gains approximately $0.50 for every $1 the stock rises — without the high cost of deep in-the-money contracts or the long-shot odds of deep out-of-the-money ones.
