Example Data Table
| Input | Example Value | Meaning |
|---|---|---|
| Long Put Strike | 90 | Protects the lower side |
| Short Put Strike | 95 | Lower sold option |
| Short Call Strike | 105 | Upper sold option |
| Long Call Strike | 110 | Protects the upper side |
| Net Premium | 1.65 Credit | Credit before fees |
Formula Used
Gross credit per share = short put premium + short call premium - long put premium - long call premium.
Total fees = commission per leg per contract × 4 × contracts + other fees.
Net credit = gross credit per share × contract multiplier × contracts - total fees.
Put spread width = short put strike - long put strike.
Call spread width = long call strike - short call strike.
Maximum profit = net credit after fees.
Maximum loss = widest spread width × contract multiplier × contracts - gross credit total + total fees.
Lower break-even = short put strike - net credit per share.
Upper break-even = short call strike + net credit per share.
Expiration payoff = long put intrinsic - short put intrinsic - short call intrinsic + long call intrinsic.
Total profit = expiration payoff + gross premium credit - fees.

Advanced Iron Condor Planning
An iron condor is a defined risk options spread. It sells one put spread and one call spread. Traders often use it when they expect price to stay inside a range. This calculator turns each leg into a clear expiration model. It separates option payoff from total profit. That makes the trade easier to inspect.
Why The Inputs Matter
Every strike controls a different edge of the position. The long put limits downside loss. The short put creates lower side credit. The short call creates upper side credit. The long call limits upside loss. Premiums decide the net credit. Contract size and quantity scale every number. Fees reduce the final result, so they are included.
Risk And Reward View
The best result usually happens between the short put and short call. In that zone, all options expire worthless. The trader keeps the net credit after costs. Loss begins when price moves beyond a break-even point. The worst case occurs beyond the protective long strikes. Unequal wings can create different side risk, so the calculator uses the larger spread width for maximum loss.
Scenario Testing
A single expiration price is useful, but a range is better. The scenario table shows possible outcomes across many prices. It helps reveal where profit fades, where loss starts, and how quickly risk grows. CSV export supports spreadsheet review. The PDF button creates a simple record for notes or trade journals.
Practical Use
Use this tool before opening, adjusting, or reviewing a position. Enter realistic premiums and include commissions. Check strike order carefully. Compare max profit against max loss. Review break-even prices before sizing the trade. The result does not predict market direction. It shows the expiration math for the values entered. Real trades may differ because of assignment, liquidity, volatility, taxes, and closing costs.
Position Management Notes
Many traders close iron condors before expiration. Early exits may lock profits or reduce sudden gap risk. Adjustments can move strikes, reduce size, or close one tested side. The calculator is still helpful after entry. Update premiums with current marks. Then compare the new payoff with the original plan. This builds discipline. It also supports clearer reviews with mentors, teams, or personal journals later.
FAQs
What is an iron condor?
An iron condor is a four-leg options spread. It combines a short put spread and a short call spread. It has limited profit and limited loss.
What is maximum profit?
Maximum profit is usually the net credit received after costs. It happens when the underlying expires between the short put and short call strikes.
What is maximum loss?
Maximum loss is based on the widest spread width minus the gross credit, plus fees. It occurs beyond the protective long strikes.
Why do fees matter?
Fees reduce the final credit and lower the true profit. They also affect break-even prices and return on risk.
Can the wings be unequal?
Yes. Unequal wings are allowed. The calculator uses the larger spread width when estimating maximum loss.
What does payoff mean?
Payoff means option intrinsic value at expiration before premium. Profit includes payoff, premium credit, and trading costs.
What are break-even prices?
Break-even prices show where profit becomes zero at expiration. Below or above those levels, the position can lose money.
Is this investment advice?
No. This calculator only models expiration math from your inputs. Review risk, liquidity, assignment, and taxes before trading.
