What Is a Stock Option?
A stock option is a financial contract that gives the holder the right, but not the obligation, to buy or sell a stock at a specific price before a certain expiration date.
There are two major types of stock options:
Call Options
A call option gives the buyer the right to buy shares at a predetermined strike price.
Traders purchase call options when they expect the stock price to rise.
Put Options
A put option gives the buyer the right to sell shares at a predetermined strike price.
Investors buy put options when they expect the stock price to fall.
Understanding how profits and losses are calculated is extremely important before entering any options trade.

Calculating stock option outcomes manually can become difficult because options involve multiple variables. A calculator automates the process and eliminates confusion.

How the Stock Options Calculator Works
The calculator uses standard options trading formulas to determine the potential outcome of a trade.
Required Inputs
The calculator typically requires the following inputs:
1. Current Stock Price
The current market value of the stock.
2. Strike Price
The agreed price at which the option can be exercised.
3. Option Premium
The amount paid to purchase the option contract.
4. Number of Contracts
Each contract usually represents 100 shares.
5. Future Stock Price
The expected stock price at expiration.
6. Option Type
Choose either:
- Call Option
- Put Option
Stock Options Calculation Formula
Call Option Profit Formula
For a call option:
Profit = ((Future Stock Price − Strike Price) − Premium) × Shares
If the stock price does not exceed the strike price plus premium, the trade may result in a loss.
Put Option Profit Formula
For a put option:
Profit = ((Strike Price − Future Stock Price) − Premium) × Shares
If the stock price does not fall sufficiently below the strike price, the put option may lose value.
Example of a Call Option Calculation
Suppose:
- Current stock price: $100
- Strike price: $105
- Premium paid: $3
- Number of contracts: 2
- Future stock price: $120
Step-by-Step
Calculate Intrinsic Value
$120 − $105 = $15
Subtract Premium
$15 − $3 = $12
Calculate Total Shares
2 contracts × 100 = 200 shares
Final Profit
$12 × 200 = $2,400
The estimated profit would be $2,400.
Example of a Put Option Calculation
Suppose:
- Current stock price: $90
- Strike price: $85
- Premium: $2
- Contracts: 1
- Future stock price: $70
Step-by-Step
Intrinsic Value
$85 − $70 = $15
Subtract Premium
$15 − $2 = $13
Total Shares
1 contract × 100 = 100 shares
Final Profit
$13 × 100 = $1,300
The estimated profit would be $1,300.
Understanding Breakeven Price
The breakeven point is the stock price at which the investor neither makes nor loses money.
Call Option Breakeven
Breakeven = Strike Price + Premium
Example:
- Strike price = $50
- Premium = $4
Breakeven = $54
Put Option Breakeven
Breakeven = Strike Price − Premium
Example:
- Strike price = $60
- Premium = $5
Breakeven = $55
