A call option example, worked dollar by dollar
Here is a complete call option example: buy one $200-strike call for a $5.00 premium ($500 per contract), and your breakeven at expiration is $205. Stock at $215 = +$1,000; at $202 = −$300; at $190 = −$500, a total loss. This guide walks every number. Education only — not financial advice.
The setup: one contract, five numbers
Everything below is a hypothetical teaching example on a made-up stock — call it AAPL-style ticker XYZ — not a trade recommendation. XYZ trades at $198. You believe it moves higher over the next month, so you buy one call:
| Piece | Value | What it means |
|---|---|---|
| Underlying | XYZ at $198 | The stock the contract rides on |
| Strike | $200 | Your locked-in buy price |
| Expiration | 30 days out | The deadline; after it, the contract stops existing |
| Premium | $5.00 per share | Quoted per share, but one contract covers 100 shares |
| Real cost | $5.00 × 100 = $500 | Your total outlay and your maximum possible loss |
Two derived numbers decide the whole trade. First, the breakeven at expiration:
Breakeven = strike + premium = $200 + $5.00 = $205
XYZ has to climb from $198 to $205 — about +3.5% — in 30 days just for you to get your $500 back at expiration. Second, the intrinsic-value rule that prices the contract at the deadline: a call is worth max(0, stock price − strike), per share, times 100. That single formula generates all three endings below. (Full definition at intrinsic value; the contract basics live at what is a call option.)
Three endings, exact P/L on each
| XYZ at expiration | Stock move | Call is worth | Your P/L on $500 |
|---|---|---|---|
| $215 | +8.6% | max(0, 215 − 200) = $15 → $1,500 | +$1,000 (+200%) |
| $202 | +2.0% | max(0, 202 − 200) = $2 → $200 | −$300 (−60%) |
| $190 | −4.0% | max(0, 190 − 200) → $0 | −$500 (−100%) |
Ending 1 — $215. The call finishes $15 in the money, worth $1,500. You paid $500, so you keep $1,000 — a +200% return on an +8.6% stock move. For comparison, $19,800 of XYZ shares would have gained $1,700, or +8.6%. That asymmetry is the leverage everyone buys calls for.
Ending 2 — $202. This is the ending that ambushes beginners. The stock went up — you were directionally right — and you still lost $300, because $202 is above the strike but below the $205 breakeven. The $2 of intrinsic value only refunds $200 of your $500 premium. Between strike and breakeven is a dead zone: right on direction, wrong on magnitude, negative on P/L.
Ending 3 — $190. Below the strike, the right to buy at $200 is worth nothing. The call expires worthless and the full $500 is gone — a 100% loss on a 4% dip in the stock. A shareholder would be down $800 on the same $19,800 position (−4%) and could keep waiting; the option buyer's deadline landed first. Losing the entire premium is a normal, common outcome of buying options, not a fluke — see the sourced figures on how retail options buyers actually fare at retail options profitability statistics.
What the Greeks were doing the whole time
- Delta (~0.45 at entry). Slightly out of the money, this call gains roughly $45 per contract for each $1 XYZ rises. Delta isn't fixed: as the stock climbs through $200, gamma pushes delta higher, so later dollars of the move pay more than earlier ones.
- Theta. At entry the entire $5.00 premium is time value (intrinsic = max(0, 198 − 200) = $0). Decay might start around $8–$10 per contract per day and accelerate sharply in the final week — those are illustrative magnitudes, not quotes. A flat stock is a losing trade here purely from decay. Mechanics at theta decay.
- Vega. If implied volatility deflates after you buy — say following an earnings report — the premium can drop hundreds of dollars per contract even on a green day. Direction is only one of three clocks running against a call buyer: price, time, and volatility.
The close-early alternative
You are not required to hold to expiration, and most option buyers don't. Rewind ending 1: on day 20, XYZ has already reached $210 with 10 days left. The call holds $10.00 of intrinsic value plus perhaps $1.50 of remaining time value — roughly $11.50, or $1,150 per contract (illustrative pricing). Selling there books +$650 (+130%) and hands all remaining risk to someone else. Holding on chases the extra upside of ending 1 but re-exposes you to endings 2 and 3: if XYZ slides back to $202 by expiration, the trade you could have closed at +$650 finishes at −$300 — a $950 swing. Neither choice is 'correct' in advance; that's why exit rules exist before entry.

The recap card
- Cost = premium × 100. A "$5.00" call is a $500 commitment and a $500 max loss.
- Breakeven = strike + premium = $205. Judge the trade against that line, not the strike.
- $215 → +$1,000. $202 → −$300 despite a rising stock. $190 → −$500, total loss.
- Delta pays per dollar of movement; theta charges per day of waiting; vega swings with fear.
- Closing early (e.g., +$650 at $210 with 10 days left, illustrative) trades away the best ending to dodge the worst two.
