What does this options profit calculator show?

It maps long or short call/put payoffs at expiration: interactive P&L chart, breakeven, max profit/loss, moneyness, and a dense price ladder so you can stress-test scenarios before risking premium.

Does this include time decay and Greeks?

Scenarios are expiration-style P&L (when time value is gone). Live option prices before expiration also move with implied volatility and Greeks — treat results as educational payoff diagrams.

Can I model selling options?

Yes. Switch Side to Sell (credit) for short calls or short puts. Short calls can have unlimited loss; short puts can lose heavily if the stock crashes — warnings appear when relevant.

How is call breakeven calculated?

Breakeven is strike + premium per share (for both long and short calls). Which side of breakeven is profitable flips with whether you bought or sold the option.

How is put breakeven calculated?

Breakeven is strike − premium per share. Long puts need the stock below that level; short puts want the stock at or above it.

Is this options calculator free?

Yes — free, no signup. Use it to learn payoff shapes, then size risk with our position size calculator before using real capital.

You need the stock above $105.00 at expiration to profit. Defined risk = premium paid.

Expiration P&L ignores remaining time value. Before expiration, an OTM option can still be worth more than zero because of extrinsic premium.

Formula walkthrough

Long call P&L = (max(0, S − K) − premium) × 100 × contracts

Long put P&L = (max(0, K − S) − premium) × 100 × contracts

Short positions flip the sign: you earn the premium if the option expires worthless, and lose as intrinsic rises.

Breakeven — call: K + premium · put: K − premium (same formula for long or short; which side of BE is “good” flips with side).

What is an options profit calculator?

An options profit calculator maps how call and put positions make or lose money at different stock prices. This tool adds an interactive payoff diagram, buy/sell sides, moneyness, intrinsic value, and a dense P&L ladder — so you see the shape of risk before you pay (or collect) premium.

How option P&L works

Call options: Right to buy stock at the strike. Long calls profit when price rises above breakeven (strike + premium). Max loss is the premium; upside is theoretically unlimited. Short calls flip that profile.

Put options: Right to sell stock at the strike. Long puts profit when price falls below breakeven (strike − premium). Max loss is the premium; max profit is capped as the stock approaches zero. Short puts collect credit with large downside if shares collapse.

Key terms explained

Strike: Exercise price for buying (call) or selling (put) the shares.

Premium: Price per share of the option. Standard U.S. equity options control 100 shares — multiply by 100 for contract cost.

Breakeven: Stock price where P&L is zero at expiration (ignoring fees).

Intrinsic value: Immediate exercise value — call: stock − strike (if positive); put: strike − stock (if positive).

Time decay (theta): Options can lose value as expiration nears. This calculator emphasizes expiration payoff; live prices also move with volatility.

When to use calls vs puts

Buy calls when you're bullish and want defined risk vs owning shares outright. Buy puts when you're bearish or hedging a long stock position. Always know max loss first — then size with our position size calculator.

Options trading risks

You can lose 100% of premium if an option expires worthless. Time decay and implied volatility swings can hurt even if your direction is eventually right. Only trade with money you can afford to lose, and research the underlying with live stock lookup first.
