Options Profit Calculator
Calculate your profit or loss on call and put options. Enter the option type, strike price, premium paid, number of contracts, and current stock price to see your breakeven point and potential return.
How Options Profit Is Calculated
Options give you the right, but not the obligation, to buy (call) or sell (put) an underlying asset at a specified strike price before or on the expiration date. The premium is the cost you pay for this right. Each standard options contract represents 100 shares of the underlying stock.
For a call option, profit occurs when the stock price rises above the strike price plus the premium paid. For a put option, profit occurs when the stock price falls below the strike price minus the premium paid. The breakeven point is the stock price at which you neither profit nor lose money.
Formulas
Call Profit = (Stock Price - Strike Price - Premium) × 100 × Contracts
Put Profit = (Strike Price - Stock Price - Premium) × 100 × Contracts
Call Breakeven = Strike Price + Premium
Put Breakeven = Strike Price - Premium
Max Loss (Buyer) = Premium × 100 × Contracts
Call Options vs Put Options
A call option gives you the right to buy shares at the strike price. You profit when the stock rises above your breakeven point. Your maximum loss is limited to the premium paid. A put option gives you the right to sell shares at the strike price. You profit when the stock falls below your breakeven point. Puts are commonly used as portfolio insurance to protect against declines in stock value.
Options buyers have limited risk (the premium paid) but unlimited potential profit on calls. Options sellers have limited profit potential (the premium received) but potentially unlimited risk on uncovered positions. This calculator focuses on the buyer's perspective for both call and put options.
Understanding Breakeven Points
The breakeven point is the stock price at which your option trade results in zero profit and zero loss. For call options, the breakeven is the strike price plus the premium. For put options, the breakeven is the strike price minus the premium. Any movement beyond the breakeven in your favor represents profit. Understanding your breakeven helps you assess the probability of a profitable trade before entering the position.
Factors Affecting Option Prices
- Intrinsic value: The amount the option is in the money (stock price minus strike for calls).
- Time value: The premium above intrinsic value that reflects time remaining until expiration.
- Implied volatility: Higher volatility increases option premiums for both calls and puts.
- Time decay (theta): Options lose time value as expiration approaches, especially in the final 30 days.
