Butterfly Spread Calculator

A Butterfly Spread uses three strikes: buy one option at a lower strike, sell two options at a middle strike, and buy one option at a higher strike. It profits when the underlying stays near the middle strike at expiration.

Outlook

Neutral with low volatility

When it fits

Use this calculator when you expect minimal movement and want the underlying to expire at a specific price. It offers high reward relative to risk if your target is accurate.

Risk note

A Butterfly Spread has a narrow profit zone. Maximum profit occurs at only one price point, and the position loses value as the underlying moves away from the middle strike.

Butterfly Spread Calculator FAQs

What is the ideal outcome for a Butterfly Spread?

Maximum profit occurs when the underlying expires exactly at the middle strike. The position collects the full spread width minus the net premium paid.

How many breakeven points does a Butterfly Spread have?

A Butterfly Spread has two breakeven points: one below the middle strike and one above. These are calculated by adding and subtracting the net premium from the outer strikes.

Iron Condor

Neutral (range-bound)

An Iron Condor combines a bull put spread and a bear call spread. It profits when the underlying stays within a defined range between the short strikes, collecting premium from all four options.

Alternative Approaches

Different ways to achieve similar or opposite goals

Long Straddle

High volatility expected

A Long Straddle buys both a call and a put at the same strike and expiration. It profits from large price movements in either direction, regardless of which way the underlying moves.

Long Strangle

High volatility expected

A Long Strangle buys an out-of-the-money call and an out-of-the-money put with the same expiration. It costs less than a straddle but requires a larger move to profit.

Simpler Options

Easier strategies with fewer legs

Bull Call Spread

Moderately bullish

A Bull Call Spread buys one call at a lower strike and sells one call at a higher strike with the same expiration. Both risk and profit potential are defined at entry, and the net cost is lower than buying a call outright.

Bear Put Spread

Moderately bearish

A Bear Put Spread buys one put at a higher strike and sells one put at a lower strike with the same expiration. This creates a defined-risk, defined-reward position with lower cost than buying a put alone.
