Options Contract Calculator
Options trading can be both rewarding and complex. Unlike stocks, options come with additional layers—strike prices, premiums, contract sizes, and expiration dates—that directly affect potential profit or loss. Without proper tools, it’s easy to miscalculate and take unnecessary risks.
That’s where the Options Contract Calculator comes in.
This tool helps traders calculate profit, loss, breakeven points, and maximum risk/reward for both call and put options. Whether you’re new to trading or a seasoned investor, the calculator makes it easy to understand potential outcomes before entering a trade.
How to Use the Options Contract Calculator – Step by Step

- Choose Call (betting the stock goes up) or Put (betting it goes down).
- Enter the Strike Price
- The fixed price at which you can buy or sell the stock.

- Click “Calculate”
- The calculator instantly shows:

Practical Example – Call Option
Imagine you buy a call option:
- Stock Price: $50
- Strike Price: $55
- Premium: $2
- Contract Size: 100 shares
Results from the calculator:
- Maximum Loss = $200 (premium paid × 100)
- Breakeven Point = $57 ($55 + $2)
- Profit Potential = Unlimited (since stock can rise indefinitely)
If the stock rises to $65, your profit = (65–55)×100–200(65 – 55) × 100 – 200(65–55)×100–200 = $800.
