About Options Profit Calculator
Calculate options trading profit/loss. This calculator provides instant results with step-by-step explanations to help you understand the calculation process.
How to use this calculator
- Choose the option type, contract size, premium, and current or final value.
- Enter the number of contracts and any fees you paid.
- Calculate the difference between settlement value and premium.
- Multiply by the contract multiplier and number of contracts, then subtract fees.
The formula explained
$$ \text{profit/loss} = (\text{option settlement value} - \text{option premium}) \times \text{contract multiplier} - \text{fees} $$
- \(profit/loss\) = the trader's net gain or loss on the option
- \(\text{option settlement value}\) = the option's value at expiration or closing
- \(\text{option premium}\) = the price paid or received for the option
- \(\text{contract multiplier}\) = the number of shares controlled by one option contract, usually 100
- \(\text{fees}\) = commissions or other trading costs
Step by step method
- Start with the option premium and the option value at expiration or the closing price you want to evaluate.
- Find the per-contract result by subtracting the premium from the settlement value.
- Multiply that result by 100 for a standard contract, then multiply by the number of contracts.
- Subtract any fees to get the final profit or loss.
Worked example
Suppose you bought 2 call option contracts for 3 dollars each, and each contract controls 100 shares.
- The settlement value is 7 dollars and the premium was 3 dollars, so the per-share profit is \(7 - 3 = 4\) dollars.
- Each contract controls 100 shares, so one contract profit is \(4 \times 100 = 400\) dollars.
- For 2 contracts, the total before fees is \(400 \times 2 = 800\) dollars.
- If fees are 20 dollars, the final profit is \(800 - 20 = 780\) dollars.
Answer. 780 dollars profit
Tips and common mistakes
- Check whether the tool is using one contract or multiple contracts, since the multiplier changes the result a lot.
- Include fees if you want the real net profit or loss, not just the gross result.
- Remember that options can expire worthless, which can make the full premium a loss for the buyer.
- Make sure you are entering the right side of the trade, since buying and selling options behave differently.
Frequently asked questions
Does this calculator work for calls and puts?+
Yes, it can be used for both calls and puts as long as you enter the correct premium, settlement value, and contract details. The key idea is to compare the option's value at exit with what you paid or received. The result shows your net profit or loss.
Why is the contract multiplier important?+
Most standard options contracts represent 100 shares, so small price changes can become large dollar changes. If you ignore the multiplier, your result will be much too small. Always confirm the contract size used by your market or broker.
Should I include commissions and fees?+
Yes, if you want an accurate net result. Commissions, exchange fees, and other charges reduce profit or increase loss. Leaving them out gives only the gross trade result.
What if the option expires worthless?+
Then the settlement value is effectively zero for the buyer, so the premium paid is usually lost before fees. For the seller, that can mean keeping the premium, minus any fees, if the position was covered correctly. The calculator helps show that outcome clearly.
