Call Option Payoff Calculator
Calculate expiration payoff and net profit or loss for a long or standalone short call.
See how premium, total fees and contract size affect break-even.
Expiration payoff and net profit or loss
Enter your option assumptions or load the worked example.
The model values a standalone call at expiration. It excludes pre-expiry pricing, exercise, assignment, collateral and financing.

Follow worked examples and see how intrinsic value differs from net profit.
Read the call option payoff guideFormula and methodology
Call intrinsic value per unit = max(expiration price − strike, 0).
Call intrinsic value per unit = max(expiration price − strike, 0). Multiply intrinsic value and premium by total units. The long receives the payoff and pays the premium. A standalone short pays the payoff and receives the premium. Deduct total fees once from either position.
Definitions
A call has positive intrinsic value at expiration when the underlying price exceeds the strike. Premium is the per-unit amount paid by a long or received by a short. Multiply contracts by units per contract to determine the position size.
Verified worked examples
Two contracts with 100 units each, strike 50, premium 3 and expiration price 54 produce total intrinsic value of 800 and premium of 600. With fees of 10, the long gains 190 and the short loses 210. Break-even prices are 53.05 and 52.95 respectively.
Interpretation
A long's worst result is the premium paid plus fees as a loss. Its upside is unbounded in the model. A standalone short's best result is received premium less fees. Its loss is unbounded. If fees consume the entire short premium, P&L is zero through strike. If fees exceed the premium, there is no break-even.
Inputs and interpretation
Choose long or standalone short. Enter the strike, underlying price at expiration, premium per unit, contract count, units per contract and total fees. Enter explicit zero where allowed.
Assumptions and limitations
One call position at one expiration checkpoint. Use one major currency throughout. The same premium and intrinsic values are scaled by the supplied contract count and units per contract. The calculator applies the supplied fee once.
Supported domain and common mistakes
Strike is positive. Expiration price, premium and total fees are nonnegative. Money inputs support up to 1 trillion and 12 fractional places. Contract count and multiplier are whole numbers from 1 to 1 million. A unique break-even uses 24 significant digits and can exceed the scenario input ceiling.
Use a premium per unit. If a quote is already a total per contract, convert it first. Being in the money only establishes positive intrinsic value. Net profit also depends on premium and fees.
