Covered Put Option Calculator

This covered put option calculator helps investors determine the potential income and risk of a covered put strategy. By selling put options on shares you own, you can generate income while limiting your downside risk.

What is a Covered Put?

A covered put is an options strategy where an investor sells a put option on shares they already own. This strategy combines the benefits of owning shares with the income potential of selling options.

Key Benefits

Generates income from option premiums
Limits downside risk to the strike price of the put
Allows investors to maintain ownership of the underlying stock
Can be used to hedge against market declines

Potential Risks

Time decay (theta) can reduce option premiums
If the stock price falls below the strike price, the put buyer exercises the option
Requires finding buyers for the put options

Covered puts are most effective when the underlying stock is expected to remain stable or increase in value, but you want to generate income from selling options.

How to Use This Calculator

Enter the current stock price of the shares you own
Input the strike price of the put option you plan to sell
Specify the option premium you expect to receive
Enter the number of shares you own and the number of contracts you plan to sell
Click "Calculate" to see your potential income and risk

The calculator will show you the maximum loss, potential income, and break-even price for your covered put strategy.

Formula Used

Maximum Loss: (Strike Price - Stock Price) × Shares per Contract × Number of Contracts

Potential Income: Option Premium × Number of Contracts

Break-even Price: Strike Price - (Option Premium / Shares per Contract)

These formulas help you understand the financial implications of your covered put strategy before executing the trade.

Worked Example

Suppose you own 100 shares of XYZ stock currently trading at $50. You sell 2 put options with a strike price of $45 and receive $2.50 per contract.

Calculations:

Maximum Loss: ($45 - $50) × 100 × 2 = $100
Potential Income: $2.50 × 2 = $5.00
Break-even Price: $45 - ($2.50 / 100) = $44.75

This means you could lose up to $100 if the stock falls below $45, but you'll earn $5 from the option premiums if the stock remains above $44.75.
