Work out how many forex lots to trade based on your account balance, risk percent, stop distance in pips and pip value.
How the lot size calculator works
This tool turns your risk plan into a lot size you can enter on your trading platform.
Formula
- Risk amount = balance × risk percent.
- Lots = risk amount ÷ (stop in pips × pip value per standard lot).
Worked example
A 10,000 dollar account risks 1 percent, or 100 dollars. The stop is 25 pips on EUR/USD, where one standard lot is worth 10 dollars per pip. Lots = 100 ÷ (25 × 10) = 0.40 lots, or 4 mini lots.
