Long Straddle Calculator

neutral

A long straddle involves buying both a call and a put at the same strike and expiration. You profit from a big move in either direction — you just need the stock to move far enough to cover the cost of both premiums.

Max Profit
Unlimited (upside) / Strike − Total premium (downside)
Max Loss
Total premium paid (both legs) × 100
Break Even
Strike ± Total premium

When to Use a Long Straddle

  • You expect a big move but don't know the direction
  • Before earnings, FDA decisions, or other binary events
  • Implied volatility is low relative to expected actual move
  • You want unlimited profit potential on both sides

Risks

  • Expensive — you pay two premiums, so the stock must move significantly
  • Time decay is brutal — two long options decaying simultaneously
  • IV crush after the event can destroy value even if the stock moves

How a Long Straddle Works


Buy a call and a put at the same strike price and expiration. Your payoff is V-shaped: you profit if the stock moves far enough in either direction.


Example

AAPL at $195. Buy the $195 call for $3.80 and the $195 put for $3.40. Total cost: $7.20 ($720).


  • AAPL at $210: Call worth $15, put worthless. Profit = ($15 − $7.20) × 100 = $780.
  • AAPL at $180: Put worth $15, call worthless. Profit = ($15 − $7.20) × 100 = $780.
  • AAPL at $195: Both expire ATM/worthless. Loss = $720.
  • Break-evens: $187.80 and $202.20.

  • Key Takeaway

    Straddles are pure volatility bets. You're paying for gamma — the right to profit from a big move. The key risk is IV crush: if you buy before earnings and IV drops after, you can lose even if the stock moves.
