Call and Put Options Explained With Simple Examples

Every options strategy, no matter how complex, is built from two pieces: call options and put options. Understanding these four basic positions — buy call, sell call, buy put, sell put — is the foundation of options trading.

We will use simple round numbers for illustration. Lot sizes and real premiums vary; always check current contract details.

Buying a call (long call)

You expect the price to rise.

• Index at 25,000. You buy the 25,000 call for a premium of 150.
• Breakeven at expiry: 25,000 + 150 = 25,150.
• At expiry, if the index is at 25,400: value = 400, profit = 400 − 150 = 250 per unit.
• If the index is at or below 25,000: the option expires worthless; loss = 150 per unit.

Maximum loss: premium paid. Maximum profit: unlimited in theory.

Selling a call (short call)

You expect the price to stay below the strike.

• You sell the 25,000 call and receive 150.
• At expiry below 25,000: you keep 150.
• At 25,400: you lose 400 − 150 = 250 per unit.
• The higher the price goes, the larger the loss.

Maximum profit: premium received. Maximum loss: unlimited for a naked short call. That is why naked call selling requires large margin and strict risk control.

Buying a put (long put)

You expect the price to fall.

• Index at 25,000. You buy the 25,000 put for 140.
• Breakeven: 25,000 − 140 = 24,860.
• At expiry 24,600: value = 400, profit = 260 per unit.
• At or above 25,000: loss = 140.

Maximum loss: premium. Maximum profit: large (if the price falls sharply).

Long puts are also used as insurance for a portfolio — see the protective put.

Selling a put (short put)

You expect the price to stay above the strike.

• You sell the 25,000 put and receive 140.
• At expiry above 25,000: you keep 140.
• At 24,600: you lose 400 − 140 = 260 per unit.

Maximum profit: premium. Maximum loss: large if the price collapses.

The four positions at a glance

ITM, ATM and OTM

• Call ITM: strike below current price (has intrinsic value).
• Call OTM: strike above current price (only time value).
• Put ITM: strike above current price.
• Put OTM: strike below current price.
• ATM: strike near the current price.

OTM options are cheaper but need a bigger move to profit — one reason many cheap OTM options expire worthless.

Why premiums change before expiry

Before expiry, a premium depends on the underlying price, time left, implied volatility and interest rates. Even if the price does not move, the premium usually falls as expiry approaches (time decay). Read option Greeks explained.

Key takeaways

• Calls are the right to buy; puts are the right to sell.
• Buyers pay premium with limited loss; sellers receive premium with large potential loss.
• Breakeven = strike ± premium at expiry.
• Premiums lose time value as expiry nears.

Frequently asked questions

What is the difference between a call and a put?

A call profits when the price rises above strike plus premium; a put profits when the price falls below strike minus premium.

Can I lose more than I invest in options?

As a buyer, no — your loss is limited to the premium. As a seller, yes — losses can exceed the premium received.

Should beginners buy or sell options?

Beginners should learn with small, defined-risk positions. Buying spreads is a common way to limit both cost and risk.
