An iron condor is one of the most popular options income strategies. It profits when the underlying stays within a range. But how do you know exactly where that profitable range ends?

That is where break-even points (BEPs) come in.

What Is an Iron Condor?

An iron condor combines four option legs:

Sell an out-of-the-money (OTM) put
Buy a further OTM put (lower strike)
Sell an OTM call
Buy a further OTM call (higher strike)

You collect a net credit when entering the trade. Your maximum profit is that credit, and it occurs when the underlying expires between your two short strikes.

The Break-Even Formula

An iron condor has two break-even points:

Lower BEP = Short Put Strike - Net Credit Received

Upper BEP = Short Call Strike + Net Credit Received

Example

Suppose you sell an SPY iron condor:

Buy 440 Put at $1.50
Sell 445 Put at $3.00
Sell 460 Call at $2.80
Buy 465 Call at $1.30

Net Credit = ($3.00 + $2.80) - ($1.50 + $1.30) = $3.00 per share ($300 per contract)

Lower BEP = $445 - $3.00 = $442.00

Upper BEP = $460 + $3.00 = $463.00

As long as SPY stays between $442 and $463 at expiration, you profit.

Why BEP Matters

Knowing your break-even points helps you:

Set alerts when the underlying approaches danger zones
Compare strategies by looking at the width of the profitable range
Decide when to adjust or close early
Calculate probability of profit using delta as a rough proxy

Common Mistakes

Forgetting commissions — they reduce your net credit and narrow your BEP range
Ignoring assignment risk — American-style options can be assigned early, especially near ex-dividend dates
Not accounting for fees — exchange fees and regulatory fees add up on 4-leg trades

How TradeEdge Automates This

When you log an iron condor trade in TradeEdge, the Strategy Metrics card automatically calculates:

Both break-even points
Maximum profit (the net credit)
Maximum loss (spread width minus credit)
Risk:reward ratio
Percentage of max profit captured at close

TradeEdge supports BEP calculations for 36 different options strategies, from simple long calls to complex butterflies and ratio spreads. No manual math required.

Key Takeaway

The iron condor break-even formula is straightforward: subtract the credit from the short put strike, add it to the short call strike. The wider the credit relative to the spread width, the more room you have for error.
