A profit and loss calculator (P&L calculator) helps traders determine the potential monetary outcome of a trade before entering it. Whether you're going long or short on EUR/USD, Bitcoin, or gold, this calculator shows you exactly how much you'll make or lose if the price reaches your target or hits your stop loss. The calculator multiplies your position size by the price difference between entry and exit points. Professional traders use P&L calculations to assess every trade's viability and ensure the potential reward justifies the risk.
The Profit & Loss Formula
The fundamental P&L formulas for long and short positions are:
For Long (Buy) Positions:
Profit/Loss = (Exit Price - Entry Price) × Position Size × Pip Value
For Short (Sell) Positions:
Profit/Loss = (Entry Price - Exit Price) × Position Size × Pip Value
Simplified:
Profit/Loss = Price Difference × Units × Pip Value per Unit
For standard lot forex trading, the pip value is typically $10 per pip for major pairs. For metals like gold, it's $10 per pip. Crypto varies by asset—BTC is often $1 per pip, while ETH is $0.10 per pip at standard lot sizes.

Profit & Loss Calculator Examples
Practical Example — Long Trade
Scenario: You buy 0.5 lots of EUR/USD at 1.0900, expecting the price to rise to 1.0950.
Step 1: Price difference = 1.0950 - 1.0900 = 0.0050 (50 pips)
Step 2: Position size = 0.5 lots × 100,000 = 50,000 units
Step 3: Pip value per unit = 0.0001
Step 4: Profit = 0.0050 × 50,000 = $250.00
Result: Your long trade would generate a profit of $250.00 if price reaches 1.0950.
Practical Example — Short Trade
Scenario: You sell 0.3 lots of GBP/USD at 1.2700, expecting the price to fall to 1.2620.
Step 1: Price difference = 1.2700 - 1.2620 = 0.0080 (80 pips)
Step 2: Position size = 0.3 lots × 100,000 = 30,000 units
Step 3: Pip value per unit = 0.0001
Step 4: Profit = 0.0080 × 30,000 = $240.00
Result: Your short trade would generate a profit of $240.00 if price reaches 1.2620.
Frequently Asked Questions
What's the difference between long and short positions?
A long (buy) position profits when the price rises—you buy an asset hoping it will increase in value. A short (sell) position profits when the price falls—you sell an asset you don't own (borrowed from your broker) hoping to buy it back at a lower price. Both can be profitable in any market direction.
How is P&L calculated for crypto trades?
Crypto P&L follows the same principle as forex. Calculate the price difference in dollars, then multiply by your position size. For example, if Bitcoin moves from $42,000 to $44,000 (a $2,000 move) and you hold 0.1 BTC, your profit is $200. Our calculator handles major crypto pairs with appropriate pip values.
Does the P&L calculator account for spreads?
Our basic calculator gives you the gross P&L. To account for spreads, subtract the spread cost from your potential profit (or add it to your loss). For example, if EUR/USD has a 2-pip spread and you gain 50 pips, your net profit is 48 pips × $10 = $480.
What is a breakeven trade?
A breakeven trade is one where your profit equals your loss (P&L = $0). This occurs when your exit price equals your entry price minus spread costs. Reaching breakeven is better than taking a loss, as it preserves your capital for future trades.
How do I calculate P&L for JPY pairs?
JPY pairs (like USD/JPY and GBP/JPY) are quoted to 2 decimal places instead of 4. Therefore, 1 pip = 0.01. Our calculator automatically adjusts for this. If USD/JPY moves from 149.50 to 149.00 (50 pips drop), a short trade profits accordingly using the JPY pip value.
