Profit & Loss Calculator
Work out your net profit or loss on a long or short trade after fees.
Calculation Results
For education only. Not financial advice. Trading involves substantial risk of loss.
Enter your entry price, exit price, quantity and total fees to see your gross profit, net profit and return on the position. Choose long if you bought first, or short if you sold first.
The formulas
- Long: Gross P&L = (Exit − Entry) × Quantity
- Short: Gross P&L = (Entry − Exit) × Quantity
- Net P&L = Gross P&L − Total fees
- Return on position = Net P&L ÷ (Entry × Quantity)
Worked examples
Long trade. Buy 100 shares at $50, sell at $53, total fees $4. Gross = $300, net = $296. Position cost was $5,000, so the return on position is 5.92%.
Short trade. Sell 100 shares at $50, buy back at $47, total fees $4. Gross = $300, net = $296.
Why fees matter
Fees are fixed per trade, so they hurt small wins the most. A $6 profit with $4 in fees leaves $2. If you trade often, add up your monthly fees and compare them to your total profit. Include commissions, spreads, exchange fees and overnight or funding charges. For a full round trip, enter the combined total.
Return on position is not return on account
A 5.92% return on a $5,000 position is only about 0.6% of a $50,000 account. Check both numbers. The position size calculator shows how large a position is relative to your account.
FAQ
Does this include taxes? No. Tax rules vary by country and account type, so check with a qualified tax professional.
How do I enter fees for a round trip? Add the fees for both the entry and the exit, and enter the total.
Can I use it for forex or crypto? Yes. For forex, enter units, not lots. For crypto, fractional quantities work.
