Lesson 3: Payoff vs P&L

Promise: Stop making the #1 beginner error. Payoff ≠ Profit.

The Critical Distinction​

In Lesson 2, you learned to identify whether an option is ITM or OTM. But being ITM doesn't mean you made money.

ConceptWhat It IsFormula
PayoffCash received at expirymax(0, S - K) for calls
P&LPayoff minus what you paidPayoff - Premium
The #1 Beginner Mistake

An option can be ITM and still lose money. If your payoff is less than the premium you paid, you lost.

See It In Action​

Drag the sliders to explore how payoff and P&L differ. Notice the orange "danger zone" between strike and breakeven.

ITM but still losing. Payoff ($2k) is less than premium ($5k). Need settlement > $105k to profit.

The gray Payoff line shows what you receive at expiry. The blue P&L line shows your actual profit or loss after subtracting the premium you paid. The green BE marker is your breakeven price.

Key Line

"P&L is payoff shifted down by the premium."

Breakeven Is Not Strike​

Many beginners assume they profit once the option is ITM. Wrong. You profit when the payoff exceeds your premium.

PositionBreakeven
Long CallStrike + Premium
Long PutStrike - Premium

Example: You buy a $100k call for $5k premium. Your breakeven is $105k, not $100k.

If BTC settles at $103k, you're ITM but still down $2k.

Key Line

"Breakeven is not strike."

The Three Scenarios​

You bought a $100k call for $3k. Where does BTC settle?

The middle row is the trap. Positive payoff, negative P&L.

Max Loss and Max Gain​

For long options, max loss is always the premium. This is why options are attractive for defined-risk trading.

Common Mistakes​

MistakeCorrection
"I'm ITM, I'm winning"ITM only means payoff > 0. P&L could still be negative.
"Max loss is the strike"Max loss for longs is the premium, not the strike.
Ignoring breakevenYou don't profit until S exceeds breakeven, not strike.
Comparing payoff shapes without premiumAlways compare P&L. Premium changes everything.

Test your understanding before moving on.

Q: Premium is $2k, payoff is $5k. What's your P&L?
Q: Strike is $100k, premium is $4k. What's breakeven for a long call?
Q: BTC settles at $102k on your $100k call. Premium was $5k. Profit or loss?

💡 Tip: Try answering each question yourself before revealing the answer.
