Options profit calculator: calls and puts at expiry

Pick a long or short call or put, enter the strike, the premium and where the stock finishes at expiry, and see the profit or loss, the break-even and the maximum profit and loss.

How to use it

  1. Pick long call, long put, short call or short put.
  2. Enter the strike, the premium per share and the number of contracts.
  3. Enter the stock price at expiry.
  4. Read the profit or loss, break-even, max profit and max loss.
Long call P/L = (max(price − strike, 0) − premium) × 100 × contracts
Example. Long call, strike 100, premium 2.50, stock at expiry 108: intrinsic 8 − 2.50 = $5.50 per share, +$550 per contract, break-even 102.50.

About this calculator

A long call or put risks only the premium; a short option collects the premium but can lose much more. At expiry an option is worth its intrinsic value, so profit is intrinsic value minus the premium paid (or the reverse for a seller). Before expiry the position also carries time value, which this calculator does not model. See the Black-Scholes calculator for a theoretical price before expiry.

Frequently asked questions

How do you calculate options profit?
At expiry, subtract the premium from the option's intrinsic value, then multiply by 100 per contract. For a call, intrinsic value is the stock price minus the strike (never below zero).
What is the break-even on a call option?
The strike plus the premium paid. A 100 strike call bought for 2.50 breaks even at 102.50 at expiry.
What is the max loss on a short call?
Theoretically unlimited, because the stock price has no upper bound.
