Put Option Profit Calculator
Simulate the profit or loss of a long put option position.
How Put Options Work
Buying a Put Option gives you the right to sell a stock at a specific price (Strike Price) by a certain date. You profit if the stock price falls significantly below the Strike Price minus the Premium you paid.
The Formula
Cost = Premium × 100 × Contracts
Value = Max(Strike - Stock, 0) × 100 × Contracts
Profit = Value - Cost
Break-Even Point
To make money, the stock must fall below:
Strike Price - Premium
Example: Strike $100 - Premium $2 = Break-Even $98.
Uses for Puts
- Speculation (Bearish)Betting that a stock is overvalued and will crash. High risk, high reward.
- Protection (Hedging)If you own 100 shares of Apple but fear earnings will be bad, buying a Put acts as insurance. If stock drops 20%, your Put gains value, offsetting the loss on your shares.
Scenarios
Stock Crashes (Win)
If stock falls to $100 and strike is $140, option is worth $40. If premium was $4, take home $36 per share profit.
Stock Rises (Loss)
If the stock goes up, the Put expires worthless. Your max loss is limited to the premium paid, unlike shorting stock where loss is unlimited.
Put Option Profit Formula
To calculate your total profit at expiration, determine if the stock is below your strike price. If it is, you subtract the premium you paid from the intrinsic value, and multiply by 100.
Manual Step: Finding Profit on a Tesla Put
Suppose you buy 1 Put Option for TSLA with a $200 Strike Price. The premium costs $6.00. At expiration, TSLA has dropped to $180.
