The fastest way to understand options is to walk through a real example, step by step. In this guide I'll show you exactly how a call, a put, and a premium-selling trade work — using real numbers on a real stock — so the mechanics finally click.
I'm David Jaffee, a former Wall Street investment banker and full-time options trader. Let's skip the jargon and trade through some concrete examples.
Quick Verdict:
- An options contract controls 100 shares of a stock. You pay (or collect) a premium for the right — or obligation — tied to a strike price and an expiration date.
- Buying a call profits if the stock rises; buying a put profits if it falls. Your risk is limited to the premium paid.
- Selling a put (the strategy I focus on) pays you premium upfront to take on the obligation to buy the stock at the strike — profitable if the stock stays above that strike.
- The examples below use real numbers so you can see exactly how profit and loss are calculated on each.
Try it yourself — plug in a strike, premium, and stock price below to see exactly how each trade profits or loses at expiration:
Options Profit & Loss Calculator
Enter a trade and see the profit or loss at expiration. One contract = 100 shares.

Profit / Loss at expiration

Simplified for education: shows profit/loss at expiration only (ignores commissions, early assignment, and time value before expiry). For sold options, "max loss" assumes you hold to expiration. Not financial advice.

The Building Blocks (30-Second Refresher)
Every options trade comes down to four variables:
- Underlying: the stock or ETF the option is based on (e.g., AAPL).
- Strike price: the price at which the option can be exercised.
- Expiration date: when the contract expires.
- Premium: the price of the option — what the buyer pays and the seller collects. One contract = 100 shares, so a premium quoted at $2.00 costs $200.
Example 1: Buying a Call Option
The setup: Apple (AAPL) is trading at $200. You think it will rise over the next two months, so you buy one call option with a $210 strike expiring in 60 days for a premium of $4.00 ($400 total).
If AAPL rises to $225 at expiration: your call is worth $15.00 ($1,500). You paid $400, so your profit is $1,100 — a 275% return on the premium.
If AAPL stays at or below $210: the call expires worthless and you lose the $400 premium — your maximum loss.
The appeal of buying a call is leverage and defined risk: a small amount of capital controls 100 shares, and you can never lose more than the premium. The catch — and it's a big one — is that the stock has to move enough, and fast enough, to overcome the premium and time decay. Most bought options expire worthless, which is why buying options is the losing side of the trade for most retail traders.
Example 2: Buying a Put Option
The setup: AAPL is at $200 and you think it will fall. You buy one put with a $190 strike expiring in 60 days for a $4.00 premium ($400).
If AAPL drops to $175: your put is worth $15.00 ($1,500), for a $1,100 profit.
If AAPL stays at or above $190: the put expires worthless and you lose the $400 premium.
Buying puts works the same way as buying calls, just inverted — you profit when the stock falls. Puts are also useful as insurance: owning a put on a stock you hold protects you during a crash. But as a standalone bet, buying puts has the same problem as buying calls: the odds are against you.
Example 3: Selling a Put Option (The Strategy I Actually Use)
Here's where it gets interesting — and where the probabilities flip in your favor. Instead of buying options and hoping for a big move, you sell them and collect premium, becoming the house instead of the gambler.
The setup: You'd be happy to own AAPL at $185. It's trading at $200. You sell one put with a $185 strike expiring in 45 days and collect a $3.00 premium ($300) upfront.
If AAPL stays above $185 (the most likely outcome): the put expires worthless and you keep the entire $300 as profit. You risked buying-power, not cash, and you won by simply having the stock not fall below your strike.
If AAPL falls below $185: you're assigned and buy 100 shares at $185 — a stock you wanted anyway — at an effective cost of $182 after the premium. Then you can sell covered calls against it or wait for recovery.
This is the core insight: when you sell a put on a quality stock you'd want to own, you profit in the most likely scenario (the stock stays flat or rises) and your "worst case" is owning a good company at a discount. That's a fundamentally better risk profile than buying lottery-ticket options.

Example 4: A Defined-Risk Vertical Spread
The setup: Same AAPL at $200. Instead of selling a naked put, you sell the $185 put for $3.00 and buy the $180 put for $1.50, collecting a net $1.50 ($150) credit.
Max profit: $150 (the net credit), if AAPL stays above $185.
Max loss: the width of the strikes ($5.00) minus the credit ($1.50) = $3.50 ($350), no matter how far AAPL falls.
The spread collects less premium than the naked put, but it caps your maximum loss — which is why it's the safer choice for most traders, especially on accounts under $20,000. You give up a little income for a lot of protection against a black-swan crash.
Putting It Together: Profit & Loss at a Glance
Trade | You profit when... | Max gain | Max loss |
|---|---|---|---|
Buy a call | Stock rises above strike + premium | Large (leveraged) | Premium paid |
Buy a put | Stock falls below strike − premium | Large (leveraged) | Premium paid |
Sell a put | Stock stays above strike | Premium collected | Strike − premium (if stock → $0) |
Vertical credit spread | Stock stays above short strike | Net credit | Strike width − credit (defined) |
Which Example Should You Actually Trade?
For most people building consistent income, the answer is the last two: selling premium with defined risk. Buying calls and puts (Examples 1 and 2) is exciting and occasionally lucrative, but it's the low-probability side of the market where most retail traders slowly lose money. Selling puts and spreads (Examples 3 and 4) puts the probabilities on your side — you're the insurance company collecting premium, not the customer buying a lottery ticket.
That's the foundation of what I teach: selling option premium with debit-spread hedging (the Financed Bull).

Frequently Asked Questions (FAQs)
What is an example of options trading?
A simple example: AAPL is at $200, you buy a $210 call for $4.00 ($400) expiring in 60 days. If AAPL rises to $225, the call is worth $1,500 for an $1,100 profit; if it stays below $210, you lose the $400 premium. That's a basic long-call trade — see the three other worked examples above for puts and premium selling.
How does an options contract work?
One options contract controls 100 shares. It has a strike price, an expiration date, and a premium (its price). Buyers pay the premium for the right to buy (call) or sell (put) at the strike; sellers collect the premium and take on the corresponding obligation.
What's a good options trading example for beginners?
Selling a cash-secured put on a stock you'd want to own is the best beginner example, because you profit in the most likely scenario (the stock stays flat or rises) and your worst case is buying a quality stock at a discount. See Example 3 above for the exact numbers.
How do you calculate profit on an options trade?
For a bought option: (option's value at close − premium paid) × 100. For a sold option: you keep the premium collected if it expires worthless, or subtract your assignment/closing cost. Each worked example above shows the full calculation.
Is buying or selling options more profitable?
For most retail traders, selling premium is more consistently profitable, because most options expire worthless — which favors the seller. Buying options can produce big wins but has a low probability of profit per trade, so over many trades most buyers lose money.
What's the safest options trading example?
A defined-risk vertical credit spread (Example 4). You collect a smaller premium but cap your maximum loss at the strike width minus the credit, no matter how far the stock moves — ideal for smaller accounts and black-swan protection.
