Breakeven Formulas
Call Intrinsic = max(0, S - K)
Put Intrinsic = max(0, K - S)
Long Leg PnL = Intrinsic - Premium
Short Leg PnL = Premium - Intrinsic
Total PnL(S) = Sum(Leg PnL x Quantity)
Breakeven = S where Total PnL(S) = 0
Worked Examples
Example 1: Iron Condor on SPY
You sell an iron condor on SPY: sell the 440 put, buy the 435 put, sell the 450 call, and buy the 455 call. The net credit collected is $2.00 per share ($200 per contract).
- Lower breakeven = Short put strike − Net credit = 440 − 2.00 = $438.00
- Upper breakeven = Short call strike + Net credit = 450 + 2.00 = $452.00
- Max profit = $200 (if SPY expires between $438 and $452)
- Max loss = Spread width − Net credit = (5.00 − 2.00) × 100 = $300
Example 2: Bull Call Spread
You buy a bull call spread: buy the 100 call and sell the 110 call for a net debit of $3.00 per share ($300 per contract).
- Breakeven = Long call strike + Net debit = 100 + 3.00 = $103.00
- Max profit = Spread width − Net debit = (10.00 − 3.00) × 100 = $700
- Max loss = Net debit paid = $300
How to Use This Calculator
- Select a strategy preset — choose iron condor, straddle, strangle, or a spread, or add legs manually for custom strategies.
- Enter strike prices — input the strike for each leg of your position.
- Enter premiums — enter the premium paid or received for each leg. Use positive values for premiums paid (long legs) and the calculator will handle the sign for short legs.
- Set quantity — enter the number of contracts for each leg. Most multi-leg strategies use 1:1 ratios.
- Click Calculate — the calculator sweeps through a price range and identifies where total P/L crosses zero, giving you all breakeven points.
- Review the output — note the lower and upper breakevens (if applicable), max profit zone, and max loss on either side.
Frequently Asked Questions
- What is a breakeven point in options?
- The breakeven point is the underlying price at which your position produces exactly zero profit or loss at expiration, after accounting for all premiums paid and received. Any price above (for longs) or inside (for spreads) the breakeven results in a profit.
- How many breakeven points can a strategy have?
- Simple directional strategies like a long call or long put have one breakeven. Strategies with both a profit zone and two loss zones — like iron condors, straddles, and strangles — have two breakevens, one on each side of the profit range.
- Why do iron condors have two breakeven points?
- An iron condor profits when the underlying stays between the two short strikes. The net credit collected widens the profit zone slightly beyond those strikes in both directions, creating a lower and an upper breakeven where profit transitions to loss.
- How do commissions affect my breakeven?
- Commissions increase the effective cost of the trade and narrow the profit zone. For a net credit trade, commissions reduce the credit received, which moves both breakevens inward. For a net debit trade, they increase the debit, pushing the breakeven further away.
- What about early assignment risk?
- This calculator assumes European-style expiration math. American-style options (like equity options) carry early assignment risk, particularly when a short leg goes deep in-the-money or a dividend is approaching. Early assignment can change your actual P/L versus what the calculator shows.
