What this calculator does
The Naked Put Calculator (Short Put) allows you to estimate profit, income, and significant downside risk for selling put options. It calculates your **total upfront credit**, identifies the **breakeven price** per share, and provides a **payoff diagram** to visualize how your position performs as the stock price fluctuates.
How the naked put strategy works
A naked put is a neutral to bullish strategy where you sell a put option without having a short stock position. You receive an immediate **premium payment**. In exchange, you agree to buy the underlying stock at the **strike price** if the buyer chooses to exercise their right. You profit if the stock stays above the strike price, as the option will expire worthless and you keep the premium.
Key Formulas
Max Loss = (Strike Price × 100) - Total Premium Received
Breakeven Price = Strike Price - Option Premium Per Share
Profit @ Expiration = Premium Received - Max(0, Strike Price - Stock Price)
When traders use this strategy
Traders sell naked puts to generate income or to eventually acquire a stock at a discount to the current price. It is popular in neutral or slightly bullish markets where the trader expects a "floor" under the stock price.
Risks to understand
The primary risk is a large move down in the stock price. If the stock crashes toward zero, you are still obligated to buy it at the agreed-upon strike price, which could result in a massive realized loss. **Margin requirements** are substantial for naked positions and can lead to liquidation if you don't have enough collateral.
Example Interpretation
Look at the Scenario Analysis Table above. For a stock at $100, if you sold a $95 Put for $2.50, your breakeven is $92.50. You will see positive profit values (green) for any scenario move where the stock price stays above $92.50. Large negative percentage moves (-20%) will show a "Option Intrinsic Value" that exceeds your premium, resulting in a net loss.
Frequently Asked Questions
What is a naked put?
A naked put is a short put position where the seller does not have cash set aside or a short stock position to cover the full potentially required capital if assigned.
How do you calculate naked put profit?
Profit is the initial premium received minus any "in-the-money" value of the put at expiration. If the stock is above the strike, the profit is 100% of the premium.
What is the maximum profit on a naked put?
The maximum profit is limited to the credit received when you first sold the put option.
What happens if the stock falls below the strike?
You may be "assigned," meaning you will be forced to purchase 100 shares of the stock per contract at the strike price, regardless of how much lower the market price is.
