Practical Example of Lot Size Calculation

Let’s understand how the calculator works with a real trading scenario.

Input Values:

• Account Balance: $5,000
• Risk Per Trade: 2%
• Stop Loss: 50 pips
• Take Profit: 100 pips
• Pair Type: Major (USD pairs)
• Lot Multiplier: Standard

Step-by-Step Output:

1. Risk Amount

2% of $5,000 = $100 risk per trade

2. Lot Size Calculation

Based on SL and pip value:

• Lot Size = (Risk ÷ (SL × Pip Value))
• Lot Size = (100 ÷ (50 × 10)) = 0.20 lots

3. Potential Profit

• 0.20 × 100 × 10 = $200 profit

4. Potential Loss

• Fixed at $100 (risk amount)

5. Reward Ratio

• 100 / 50 = 2.0

6. Trade Quality

• Since RR = 2 → High Quality Trade
