Payoff at expiration
Long call P/L = (max(0, S − K) − premium) × 100 × contracts
Long put P/L = (max(0, K − S) − premium) × 100 × contracts
Short positions: the opposite sign
Breakeven for a call is strike + premium; for a put, strike − premium. Example: buy one $100 call for $3.50; at $110 the profit is (10 − 3.5) × 100 = $650.
