How to Calculate Options Profit Manually: Step-by-Step Guide with Examples

What You'll Need

To calculate options profit by hand, gather the following details from your trade:

• Option type (call or put)
• Position (long or short)
• Strike price ($X per share)
• Premium ($Y per share, paid or received)
• Stock price at expiration ($Z per share)
• Number of contracts (each contract = 100 shares)
• Commission per contract (optional but recommended)

If you're unfamiliar with these terms, our What Is Options Profit? guide provides a solid foundation. For a quick reference of the formulas, see Options Profit Formulas.

Step-by-Step Manual Calculation

Follow these steps to compute profit or loss for any standard options trade.

1. Identify the option and position. Determine whether it's a call or put, and whether you bought (long) or sold (short) the option.
2. Calculate the intrinsic value at expiration. This is the amount the option is in-the-money. For a call: max(0, stock price – strike price). For a put: max(0, strike price – stock price).
3. Compute the option value per share. For long positions, the profit per share is intrinsic value – premium paid. For short positions, it's premium received – intrinsic value.
4. Multiply by 100 shares per contract. This converts per-share values to per-contract figures.
5. Subtract commissions. Multiply commission per contract by the number of contracts and subtract from gross profit.
6. Multiply by the number of contracts (if you have more than one).

That's your net profit or loss. For a deeper understanding of what these numbers mean, check out Interpreting Options Profit & Loss Results.

Worked Example 1: Long Call

Setup: You buy 1 call option on XYZ stock with a strike price of $105. You pay a premium of $3 per share ($300 total for 1 contract) and a $5 commission. The stock is at $115 at expiration.

1. Option type: Call, Long
2. Intrinsic value: max(0, $115 – $105) = $10 per share
3. Profit per share: $10 (intrinsic) – $3 (premium) = $7 per share
4. Per contract: $7 × 100 = $700
5. Subtract commission: $700 – $5 = $695
6. Number of contracts: 1, so net profit = $695

Your total profit is $695. Had the stock been below $105, the option would expire worthless, and your loss would be the $300 premium plus commission, totaling $305.

Worked Example 2: Short Put

Setup: You sell 2 put options on ABC stock with a strike price of $50. You receive a premium of $2 per share ($200 per contract). Commission is $3 per contract. The stock is at $48 at expiration.

1. Option type: Put, Short
2. Intrinsic value: max(0, $50 – $48) = $2 per share
3. Profit per share: $2 (premium received) – $2 (intrinsic value) = $0 per share
4. Per contract: $0 × 100 = $0
5. Subtract commission: $0 – ($3 × 2) = -$6 (net loss per contract? Actually the commission is a cost, so overall profit = -$6 for two contracts?) Let's recalc stepwise: per contract before commission: $0; after commission: -$3 per contract; total for two contracts: -$6. But this is a loss because commission > profit. In reality, the premium received covers the intrinsic value exactly, but commission eats into profit. So net loss of $6.
6. Net profit: -$6 (loss).

If the stock had stayed above $50, the put would expire worthless, and you'd keep the full $400 premium minus $6 commission = $394 profit.

Common Pitfalls

• Forgetting to multiply by 100. Options are priced per share, but contracts represent 100 shares. Always multiply by 100.
• Using the wrong intrinsic value formula. Calls and puts are opposite – double-check before calculating.
• Confusing long and short positions. Long positions pay premium upfront; short positions collect premium and may owe intrinsic value.
• Ignoring commissions. They can turn a small profit into a loss, especially for low‑premium options.
• Neglecting the number of contracts. Multiply per-contract values by the total contracts.
