Lot Size Calculator (Forex)

How to Calculate Forex Lot Size
Lot sizing in forex determines the volume of your trade. Trading the wrong lot size can lead to outsized losses, even with a tight stop loss. This calculator helps you trade the correct volume every time.
The Formula
Lots = (Account Size × Risk %) ÷ (Pips at Risk × Pip Value)
Step-by-Step Example
- Your account is $10,000
- You want to risk 2% ($200)
- EUR/USD entry at 1.1000, stop at 1.0950
- That is 50 pips of risk
- Pip value (standard lot) = $10
- Lots = $200 ÷ (50 × $10) = 0.40 lots
