5. Click "Calculate" to see the potential profit or loss.

The calculator will display the maximum potential profit, break-even price, and other key metrics to help you make an informed decision.

How Put Options Work

Put options are financial derivatives that give the buyer the right, but not the obligation, to sell an underlying asset at a specified price (the strike price) on or before a certain date (the expiration date).

Key Components of a Put Option

• Strike Price: The price at which the option holder can sell the underlying asset.
• Premium: The price paid to purchase the put option.
• Expiration Date: The last date the option can be exercised.
• Break-Even Price: The price at which the option buyer neither gains nor loses money.

Calculating Potential Profit

The maximum potential profit from a put option is the difference between the strike price and the premium paid. If the underlying asset's price falls below the strike price, the option holder can sell it at the strike price, realizing a profit.

The break-even price is calculated as follows:

If the underlying asset's price falls below the break-even price, the option buyer will make a profit.

Worked Example

Let's consider an example to illustrate how the put option calculator works.

Example Scenario

• Current stock price: $50
• Strike price: $45
• Premium: $2
• Expiration date: 30 days from now

Calculations

Using the formulas provided:

In this scenario, the maximum potential profit is $43, and the break-even price is $43. If the stock price falls below $43 at expiration, the option buyer will make a profit.
