Put Spread Calculator

The Put Spread Calculator by GammaWins allows you to visualize the Profit and Loss (P/L) and Greeks of any put spread on US equity options. You can select any time before expiry and visualize your strategy at that point in time.

Pro users can see the volatility skew chart alongside one year of historical ranges and directly adjust the strikes on it. The skew chart is available to first-time users for a limited amount of time for exploration.

The calculator is preloaded with a 30DTE 20 delta Credit Put Spread (a.k.a Bull Put Spread) on SPY. Simply choose the ticker and contracts of your choice to analyze your own strategy.
