Put Sell Calculator

Use our put sell calculator to determine the value of selling a put option. Calculate potential profit, break-even price, and risk based on your option parameters.

How to Use This Calculator

To calculate the value of selling a put option, follow these steps:

Enter the current stock price
Input the strike price of the put option
Specify the premium received for selling the put
Enter the number of shares per contract (typically 100)
Click "Calculate" to see your results

The calculator will show you the maximum loss, break-even price, and potential profit from selling the put option.

Formula Explained

The put sell calculator uses the following formulas:

Maximum Loss = (Strike Price - Current Price) × Shares per Contract Break-even Price = Strike Price - (Premium Received / Shares per Contract) Potential Profit = Premium Received × Shares per Contract

Where:

Strike Price - The price at which the put option can be exercised
Current Price - The current market price of the underlying stock
Premium Received - The amount paid to sell the put option
Shares per Contract - Typically 100 shares for standard options

Worked Example

Let's calculate the value of selling a put option with these parameters:

Current stock price: $50
Strike price: $45
Premium received: $1.50 per share
Shares per contract: 100

Example Calculation

Maximum Loss: ($45 - $50) × 100 = $500

Break-even Price: $45 - ($1.50 / 100) = $44.985

Potential Profit: $1.50 × 100 = $150

This means you could lose up to $500 if the stock price stays above $44.99, but you could make $150 if the stock price falls below $45.

Interpreting Results

The calculator provides three key metrics:

Maximum Loss: The worst-case scenario if the stock price stays above the break-even price
Break-even Price: The stock price at which you neither profit nor lose money from selling the put
Potential Profit: The maximum profit you could make if the stock price falls below the strike price

Important Notes

This calculator assumes you sell the put at the money (strike price equals current price)
Real-world results may vary due to market conditions and option pricing models
Always consider your risk tolerance and investment goals before selling options
