How Profit and Loss Is Calculated in Forex
Forex profit is determined by three factors: the price difference between entry and exit, the position size, and the pip value of the pair. The calculation is straightforward once you understand how these three variables interact.
P&L = (Exit Price − Entry Price) × Position SizeFor a long trade on EUR/USD: buy at 1.1000, sell at 1.1050 on 1 standard lot. The price moved 0.0050 (50 pips). Profit = 0.0050 × 100,000 = $500.00. If the trade were short, you'd enter at 1.1050 and exit at 1.1000 — same 50-pip move, same $500 profit, just in the opposite direction.
Pips vs Dollar Profit
A pip represents the smallest price movement, but the dollar value depends entirely on position size. A 50-pip move on EUR/USD yields:
| Lot Type | Lots | Units | Profit (50 pips) |
|---|---|---|---|
| Standard | 1.0 | 100,000 | $500.00 |
| Mini | 0.1 | 10,000 | $50.00 |
| Micro | 0.01 | 1,000 | $5.00 |
JPY Pairs
Japanese yen pairs quote to 2 decimal places, so 1 pip = 0.01. USD/JPY at 150.00 moving to 150.50 is a 50-pip gain. On 1 standard lot: 0.50 × 100,000 = ¥50,000. At an exchange rate of 150.00 JPY/USD, this equals approximately $333.33.
Account Currency Conversion
Profit is always calculated in the quote currency first. If your account is in a different currency, the profit must be converted. For example, trading GBP/JPY with a USD account means converting JPY profit to USD at the current rate. The calculator handles this conversion when you select your account currency and provide the current exchange rate.
