Buying a call or put? Enter the strike, the premium you paid and where the stock ends up to get your profit or loss, return on cost, break-even price, and maximum loss in one tap.
Answer first: your profit on a long option is its value at exit minus what you paid. A call is worth the stock price minus the strike (never below zero); a put is worth the strike minus the stock price. Multiply by 100 shares per contract, subtract the premium you paid, and you have your dollar profit. This options profit calculator does it instantly for long calls and long puts.
Call profit = (max(0, Price − Strike) − Premium) × 100 × contracts
Example: a $100 call bought for $5, stock finishes at $120. Intrinsic value = $20. Profit = ($20 − $5) × 100 = $1,500 on a $500 cost — a 300% return. Break-even is strike + premium = $105.
Notice the asymmetry that makes options popular: the most you can lose is the $500 premium, no matter how far the stock falls, while the upside on a call is theoretically unlimited. That capped downside is the whole appeal — and the reason options are priced the way they are.
For a long call, break-even is the strike plus the premium; the stock must clear that before you make a cent. For a long put, break-even is the strike minus the premium. In both cases the maximum loss is the premium paid — you can never lose more than you put in on a long option. The calculator reports break-even and max loss so you know the two numbers that matter before you ever open the trade.
The catch is time. This tool shows profit at exit using intrinsic value only — it does not model the time decay (theta) that eats an option's price every day it sits out of the money, nor implied-volatility swings. A call can be "right" on direction and still expire worthless if the move comes too slowly. Treat the result as the payoff at expiration, then practice the real thing risk-free in our options trading game.
Reality check: It shows the value at exit/expiration only and ignores time decay, implied volatility, commissions, and assignment risk. Real option prices move on more than direction.

A long call's value at exit is the stock price minus the strike (never below zero); a put's is the strike minus the price. Multiply by 100 shares per contract, then subtract the premium you paid. The result is your dollar profit or loss.
Break-even on a long call is the strike price plus the premium per share. The stock must rise above that level before the option makes money. For a long put, break-even is the strike minus the premium.
For a long call or put you buy, the maximum loss is the premium paid — you can never lose more than that, no matter how far the stock moves against you. That capped downside is a key feature of buying options.
No. It shows the value at exit or expiration using intrinsic value only. It does not model time decay (theta), implied volatility, commissions or early assignment, so live results can differ. Use it for planning and education.
