Call in one sentence
Call payoff = max(final stock price - strike, 0)
Profit subtracts the premium you paid.
Options without the headache
Buying a call is a bet on up. Buying a put is a bet on down. The strike price is the line in the sand. The premium is your ticket price. Selling flips the deal: you collect the ticket price and take the obligation.
First: calls
Buying a call gives you the right to buy the stock at the strike price. You want the stock to go up enough to beat both the strike and the premium you paid.
Call payoff = max(final stock price - strike, 0)
Profit subtracts the premium you paid.
The call line is flat when the stock is below the strike. After the strike, every extra dollar in the stock adds about $100 per contract before premium.
Second: puts
Buying a put gives you the right to sell the stock at the strike price. You want the stock to fall enough to beat the premium you paid.
Put payoff = max(strike - final stock price, 0)
Profit subtracts the premium you paid.
The put line rises when the stock falls below the strike. If the stock stays above the strike, the buyer's loss is the premium.
Buying a call vs. selling a put
A call buyer pays for a choice. A put seller gets paid for taking an obligation. That one sentence is the difference to remember.
You pay for a right
You get paid for an obligation
Same final stock price, different outcome
| Final AAPL | Buy $335 call for $9 | Sell $335 put for $9.50 | What happened |
|---|---|---|---|
| $360 | +$1,600 | +$950 | The call keeps the bigger upside. The put seller keeps only the premium. |
| $333.74 | -$900 | +$824 | The call is below strike. The short put loses $1.26 of its $9.50 premium. |
| $320 | -$900 | -$550 | The call loss stops at $900. The put seller is now below breakeven. |
| $280 | -$900 | -$4,550 | The call is still capped at its premium. The put obligation gets expensive. |
Third: at, in, out of the money
Same stock. Same moment. Different strikes. That is all at-the-money, in-the-money, and out-of-the-money are trying to say.
With AAPL at $333.74, the closest clean strike might be $335. It is not magic. It is just near the current price.
A $320 call is in the money because buying at $320 is cheaper than AAPL at $333.74. A $350 put is in the money because selling at $350 is better than selling at $333.74.
A $350 call needs AAPL above $350. A $320 put needs AAPL below $320. Cheaper ticket, harder target.
Fourth: strike prices
The stock can bounce around all day. The option's math keeps asking one question: did the final stock price beat the strike in the right direction?
With AAPL near $333.74, here is how the same strike looks to a call buyer and a put buyer.
Beating the strike is not enough. You also paid a premium. The stock has to move past your breakeven before the trade is profitable at expiration.
Covered strategies
These are option-selling strategies. The premium is small and immediate; the obligation behind it is much larger.
Covered call: shares already owned
You collect income now. In return, you agree to sell your 100 shares for $350 if assigned. Your stock sale price is capped at $350; including the $4.50 premium, maximum proceeds are $354.50 per share. You still carry almost all of the stock's downside.
Cash-secured put: cash kept ready
If AAPL stays at or above $320, you keep the premium. If it falls below $320 and you are assigned, you buy 100 shares at $320. After the premium, your effective price is $315.75.
Quick outcome table
| Final AAPL | Covered $350 call | Cash-secured $320 put | Plain English |
|---|---|---|---|
| $360 | +$2,076 | +$425 | Covered-call shares are sold at $350. The put seller keeps the premium. |
| $333.74 | +$450 | +$425 | Both options expire worthless; both sellers keep their premiums. |
| $320 | -$924 | +$425 | The covered call follows the shares down. The $320 put is exactly at strike. |
| $300 | -$2,924 | -$1,575 | Both lose. "Covered" and "cash-secured" do not mean risk-free. |
Payouts with real stock, simple math
These examples assume you buy one option contract. The premiums are made-up teaching numbers so the math is visible. Real option premiums change constantly.
Call example 1
Breakeven = $320 + $19 = $339.
| Final AAPL | Payoff per share | Profit per share | Profit per contract | Plain English |
|---|---|---|---|---|
| $300 | max(300 - 320, 0) = $0 | $0 - $19 = -$19 | -$1,900 | Wrong direction. You lose the ticket price. |
| $333.74 | $333.74 - $320 = $13.74 | $13.74 - $19 = -$5.26 | -$526 | In the money, but not past breakeven. |
| $360 | $360 - $320 = $40 | $40 - $19 = $21 | $2,100 | Above breakeven. Now it works. |
| $390 | $390 - $320 = $70 | $70 - $19 = $51 | $5,100 | Big upside move, big call profit. |
Call example 2
Breakeven = $335 + $9 = $344.
| Final AAPL | Payoff per share | Profit per share | Profit per contract | Plain English |
|---|---|---|---|---|
| $300 | max(300 - 335, 0) = $0 | $0 - $9 = -$9 | -$900 | Below strike. Worthless at expiration. |
| $333.74 | max(333.74 - 335, 0) = $0 | $0 - $9 = -$9 | -$900 | Close is not enough. It needs to cross the strike. |
| $360 | $360 - $335 = $25 | $25 - $9 = $16 | $1,600 | Past breakeven by $16 per share. |
| $390 | $390 - $335 = $55 | $55 - $9 = $46 | $4,600 | Cheaper than ITM, but still needs the move. |
Call example 3
Breakeven = $350 + $4.50 = $354.50.
| Final AAPL | Payoff per share | Profit per share | Profit per contract | Plain English |
|---|---|---|---|---|
| $300 | max(300 - 350, 0) = $0 | $0 - $4.50 = -$4.50 | -$450 | Cheap ticket, missed target. |
| $333.74 | max(333.74 - 350, 0) = $0 | $0 - $4.50 = -$4.50 | -$450 | Still out of the money. |
| $360 | $360 - $350 = $10 | $10 - $4.50 = $5.50 | $550 | Small win because it barely cleared breakeven. |
| $390 | $390 - $350 = $40 | $40 - $4.50 = $35.50 | $3,550 | This is why OTM calls feel explosive. |
Put example 1
Breakeven = $350 - $22 = $328.
| Final AAPL | Payoff per share | Profit per share | Profit per contract | Plain English |
|---|---|---|---|---|
| $280 | $350 - $280 = $70 | $70 - $22 = $48 | $4,800 | Big drop. Put buyer is happy. |
| $320 | $350 - $320 = $30 | $30 - $22 = $8 | $800 | Below breakeven, so profitable. |
| $333.74 | $350 - $333.74 = $16.26 | $16.26 - $22 = -$5.74 | -$574 | In the money, but premium eats the value. |
| $360 | max(350 - 360, 0) = $0 | $0 - $22 = -$22 | -$2,200 | Wrong direction. You lose the premium. |
Put example 2
Breakeven = $335 - $9.50 = $325.50.
| Final AAPL | Payoff per share | Profit per share | Profit per contract | Plain English |
|---|---|---|---|---|
| $280 | $335 - $280 = $55 | $55 - $9.50 = $45.50 | $4,550 | Large drop, strong profit. |
| $320 | $335 - $320 = $15 | $15 - $9.50 = $5.50 | $550 | Below breakeven by $5.50 per share. |
| $333.74 | $335 - $333.74 = $1.26 | $1.26 - $9.50 = -$8.24 | -$824 | Almost at the money, still a loser after premium. |
| $360 | max(335 - 360, 0) = $0 | $0 - $9.50 = -$9.50 | -$950 | Stock rose. Put expires worthless. |
Put example 3
Breakeven = $320 - $4.25 = $315.75.
| Final AAPL | Payoff per share | Profit per share | Profit per contract | Plain English |
|---|---|---|---|---|
| $280 | $320 - $280 = $40 | $40 - $4.25 = $35.75 | $3,575 | Big enough drop. OTM put pays. |
| $320 | max(320 - 320, 0) = $0 | $0 - $4.25 = -$4.25 | -$425 | At the strike is still not profit. |
| $333.74 | max(320 - 333.74, 0) = $0 | $0 - $4.25 = -$4.25 | -$425 | Still out of the money. |
| $360 | max(320 - 360, 0) = $0 | $0 - $4.25 = -$4.25 | -$425 | Wrong direction, limited loss. |
