Option Payoff at Expiration

Call value = max(0, stock − strike)   Put value = max(0, strike − stock)
Long profit = (value − premium) × 100 × contracts   Short profit = −long profit
Break-even: call = strike + premium; put = strike − premium

Tips

This shows the value at expiration only; before then, options also carry time value. Commissions, early assignment and taxes aren’t included. Selling (writing) calls without owning the shares has unlimited risk.
