About the Options Profit Calculator
This options profit calculator shows what a single call or put position is worth at expiration. Choose call or put, buy or sell, enter the strike price, the premium per share and the stock price at expiration. The tool multiplies by 100 shares per contract and returns your profit or loss, the break-even price, the maximum profit and loss, and a table of outcomes for different stock prices.
It is an educational estimate of the payoff at expiration only. It does not model time value, volatility, commissions or early assignment. This is not investment advice.
How to use it
- Choose call or put and whether you are buying or selling the option.
- Enter the strike price, the premium per share and the number of contracts.
- Enter the stock price you expect at expiration.
- Press Calculate to see profit or loss, break-even and the payoff table.
Option payoff formulas
- Long call: profit = max(stock − strike, 0) − premium. Break-even = strike + premium.
- Long put: profit = max(strike − stock, 0) − premium. Break-even = strike − premium.
- Short call / short put: the reverse of the long position. You keep the premium if the option expires worthless.
- One standard US equity option contract controls 100 shares.
Example
You buy 1 call with a $100 strike for $3.50 per share ($350). If the stock is $110 at expiration, the option is worth $10, so your profit is ($10 − $3.50) × 100 = $650. Your break-even is $103.50 and your maximum loss is the $350 premium.
Frequently asked questions
How do you calculate options profit?
For a long call, profit = max(stock price − strike, 0) − premium, then multiply by 100 shares per contract. For a long put, use max(strike − stock price, 0) − premium.
What is the break-even on a call option?
Strike price plus the premium paid. The stock must finish above that level at expiration for the buyer to profit.
What is the maximum loss when buying an option?
The premium you paid. Selling uncovered calls can have unlimited loss, so it needs careful risk control.
Does this include time value and volatility?
No. It calculates the payoff at expiration only. Before expiration, an option price also depends on time left and implied volatility.
How many shares is one options contract?
One standard US equity options contract covers 100 shares, so a $3.50 premium costs $350 per contract.
