Call Option Payoff Calculator
Calculate intrinsic payoff, net profit/loss, and expiry breakeven for long and short call contracts.
How the Calculation Works
Read parameters and compute total exposure: multiply order quantity by contract unit multiplier.
Evaluate terminal return at the selected target price using strict financial mathematical boundary logic.
Deduct upfront capital commitments, taxes, or net debits to produce final net profit or loss realization.
Calculation Formula
- S: Underlying market price at expiration
- K: Selected Call strike price
- P: Option premium paid per unit
- BE: Breakeven price = Strike (K) + Premium (P)
Example Calculation
1 lot (50 units) Nifty 24,500 Call bought at ₹180 premium with Nifty expiring at 24,800.
Intrinsic value at 24,800 is ₹300. Subtracting the ₹180 premium leaves ₹120 net profit per unit (₹6,000 total across 50 units).
Assumptions & Parameters
- Payoff reflects deterministic intrinsic expiration value; early assignment and pre-expiry theta are not modeled.
- Regulatory brokerage, STT, and exchange taxes are excluded from the mathematical line.
Frequently Asked Questions
What is a call option payoff?
A call option payoff is the cash value of the contract at expiration before deducting the initial premium paid to purchase it.
How is call option profit calculated?
Profit equals intrinsic expiration value (Underlying Price minus Strike Price, minimum zero) minus the option premium paid, multiplied by total units.
What is the breakeven price of a long call?
The breakeven price equals the Strike Price plus the Premium Paid (K + P). At this price, your intrinsic gain exactly covers the premium.
What happens if the underlying closes below the strike at expiry?
The option expires Out-of-the-Money (OTM) worthless. Your loss is strictly capped at the initial premium paid.
What is the maximum risk on a long call?
The maximum loss on a long call is 100% of the premium paid. It occurs if the underlying closes at or below the strike price.
Is the risk on a short call unlimited?
Yes. A naked short call has theoretically unlimited loss because the underlying stock price has no upper limit.
Does this calculator include brokerage and statutory taxes?
No. This tool models the mathematical derivatives payoff. Use our Indian Brokerage Calculator to estimate STT, turnover fees, and 18% GST.
Does the calculator model option pricing before expiry?
No. This engine calculates deterministic expiration payoffs. Intraday price movements before expiry depend on implied volatility and Greeks.
