CFA: Option payoffs
Explanations, applications and practice for option payoffs.
- Worked examples
Build a bear put spread and net premium
Reconcile a long higher-strike put with a short lower-strike put.
- Worked examples
Build a bull call spread by price region
Subtract the higher-strike writer amount before deducting the net premium.
- Worked examples
An in-the-money call with a negative simple profit
Reconcile a positive payoff that does not recover the premium.
- Worked examples
Calculate a collar’s terminal band and net credit
Combine stock, a lower-strike put and a higher-strike written call.
- Worked examples
Calculate a covered call’s terminal value and simple profit
Add one stock unit and a same-unit short call under an explicit record.
- Templates

Option-scenario date and value record
Distinguish current prices, terminal scenarios and dated cash amounts.
- Concepts
One expiry scenario versus an exercise policy
Separate terminal algebra from decisions or rules at earlier dates.
- Comparisons
Forward and straddle terminal exposures
Compare a signed linear outcome with a two-sided option payout.
- Common mistakes
Allowing negative holder payoff in a vanilla option
Apply the contract floor before adding the premium or writer sign.
- Tool guides
Option-expiry tool input and chart scope
Check units, date roles and plot range before interpreting the outputs.
- Careers
Explain an option-payoff record in an interview
Practice a clear model explanation with units, dates and limits.
- Concepts
Expiry payoff and pre-expiry option value
Use the appropriate date before interpreting a max expression.
- Templates

Option-position leg and premium sheet
Keep side, unit quantity and premium direction for each original leg.
- Lessons
Add option legs on a common expiry basis
Reconcile quantities, signs and premiums before combining positions.
- Formulas
European put–call parity with a discount factor
Match terminal portfolios before writing their current-value equality.
- Concepts
Option payoff and simple profit
Distinguish the contract’s terminal amount from the position’s cost-adjusted result.
- Lessons
Derive option payoffs by terminal-price region
Write the contract expression on each side of its strike.
- Common mistakes
Reading a finite payoff chart as a risk cap
Separate the displayed scenario range from the payoff function’s domain.
- Practice
Option combinations and replication boundaries
Check leg algebra, cost bases and terminal-versus-current values.
- Practice
Option signs, premiums and contract units
Check original vanilla expiry records with explained alternatives.
- Common mistakes
Dropping premium from an option profit
Inspect whether the calculation reported contract payoff as position profit.
- Worked examples
Solve a put price from a compatible parity record
Keep strike cash and its present value distinct in the current-cost equation.
- Worked examples
Calculate a protective put’s terminal floor and cost
Keep the payoff floor separate from the position’s premium-adjusted loss.
- Common mistakes
Using call subtraction for a put payoff
Recover the strike-minus-price difference in the below-strike region.
- Lessons
Separate expiry replication from current-price equality
Prove the terminal identity before applying a pricing assumption.
- Revision
Option-payoff and replication checklist
Review contract regions, premium signs, units and dates before accepting a diagram.
- Study plans
Option-payoff learning sequence
Build from one contract to a compatible multi-leg and price-identity explanation.
- Worked examples
Scale a short-call record into contract amounts
Apply the writer sign and multiplier once to every cash movement.
- Worked examples
Reconcile a short put’s premium and settlement
Use the writer’s side in an original below-strike outcome.
- Concepts
Holder and writer signs in option records
Keep the premium and settlement directions on one consistent side.
- Formulas
Signed vanilla option payoff and simple profit
Apply the position sign and unit quantity to a nonnegative holder payoff.
- Formulas
Vertical call-spread payoff by region
Derive the capped terminal amount of two same-expiry call legs.
- Comparisons
Covered-call and protective-put payoff choices
Compare the terminal cap and floor created by different stock-option legs.
- Worked examples
Calculate a long straddle’s two profit boundaries
Add the same-strike call and put payoffs before deducting both premiums.
- Worked examples
Reconcile long call minus short put at expiry
Prove a signed linear payoff from two contingent claims.
- Worked examples
Match a protective put with call plus terminal cash
Verify the terminal identity with original scenario values.
- Lessons
Build an option-position cash-flow timeline
Separate initiation premium from expiry settlement before calculating a result.
- Tools

Option expiry payoff and simple-profit calculator
Inspect calls, puts and position sides with explicit premium and contract units.
- Worked examples
A put premium above strike and an unattainable boundary
Use the nonnegative-price domain before reporting a breakeven.
- Concepts
Option contracts and underlying-unit amounts
Scale a per-unit quote into one position total without applying the multiplier twice.
