How to Calculate Call Option Profit and Loss at Expiration

Calculate the cash flows at expiration

Enter the strike, premium and position size to see how a hypothetical expiration price changes a long or standalone short call. Intrinsic value comes first, then premium and fees determine the net result.

Identify the per-unit and position amounts

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.

Test prices at and above the strike

At the strike, intrinsic value is zero. Above it, each unit of price increase adds one unit of call intrinsic value before the multiplier. This can help explain the difference between moneyness and profitability.

Calculate long and short call payoff

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.

Call intrinsic value per unit = max(expiration price − strike, 0)

Reconcile the 200-unit example

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.

At 53.05, long intrinsic value totals 610 and offsets 600 of premium and 10 of fees. At 52.95, short intrinsic value totals 590 and absorbs the 590 premium left after fees.

1. Enter strike 50, premium 3, and expiration price 54.
2. Enter two contracts, 100 units per contract and total fees of 10.
3. Compare the signed premium, expiration payoff and net P&L on both sides.

Use the terms of one position

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.

Distinguish break-even cases and payoff bounds

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.

The long with zero premium and fees has a flat zero-P&L region through strike. A unique break-even lies above strike. Fees can remove a short's break-even entirely.

Keep the scenario at expiration

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.

Understand numerical bounds and settlement exclusions

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.

The input ceiling bounds the prices you can evaluate. The theoretical payoff remains uncapped on the long gain or short loss side.

Check the premium unit and multiplier

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.

Match the actual contract specification

Choose USD, GBP, CAD, AUD or INR for the USA, UK, Canada, Australia or India. Some UK equity options are quoted in pence, so convert all per-unit values to pounds when fees are in GBP. Montréal Exchange and ASX publish contract terms, and NSE publishes lot-size information. Check the exact series and use its multiplier.

Match the calculator to the trade

Trading Break-Even solves an exit for a stock trade with transaction charges. Risk-to-Reward Ratio compares a stock stop and target. A call's expiration payoff has a kink at strike and needs its own model.

Educational scope

Educational expiration model. It excludes pre-expiry option prices, probabilities, exercise and assignment mechanics, margin, financing, FX and taxes. The short result describes a standalone position.
