Frequently Asked Questions about the Options Profit Calculator
How does this calculator compute profit at expiration?
Each leg pays its intrinsic value at expiry. A long call collects max(spot minus strike, 0); a long put collects max(strike minus spot, 0); short calls and puts pay the opposite. Net profit subtracts the premium you paid (for long legs) or adds the premium you received (for short legs), then multiplies by 100 shares per contract.
How is breakeven calculated?
Calls break even when the underlying reaches strike plus premium at expiration. Puts break even when the underlying reaches strike minus premium. The direction is the same for long and short, since both sides pivot at the same spot price; only the sign of the P/L flips.
Why does a short call show unlimited loss?
A naked short call has no upper bound on the underlying price. If the stock keeps rising above the strike, you owe the difference for every dollar above it, and that loss is theoretically unlimited. The calculator flags this with an Unlimited label rather than a dollar figure.
Why is each contract worth 100 shares?
Standard US equity options carry a contract multiplier of 100, so one contract controls 100 shares of the underlying. The calculator multiplies your per-share payoff and premium by 100 times the number of contracts you enter. You can override the multiplier for index, futures, or mini contracts that use a different size.
Is this educational only, not financial advice?
Yes. The calculator is for educational purposes only and does not constitute financial, tax, or investment advice. It assumes you hold the position to expiration, ignores commissions, fees, dividends, early assignment, and assignment risk on American-style options, and uses payoff math at a single spot price. Talk to a licensed advisor before trading options.
