Position size calculator

Risk is a decision you make before entry, not a number you discover after exit. Set the balance, the percentage you are willing to lose and where the stop sits — this returns the lot size that makes those three agree.

1–2% is the usual ceiling for a single trade.

How it works

Understanding the numbers

What does this actually calculate?

Lot size = risk amount ÷ (stop distance in pips × pip value per lot). The risk amount comes from your balance and your risk percentage; the pip value comes from the instrument's contract size and its quote currency converted into your account currency.

Why 1–2% per trade?

At 2% per trade, ten consecutive losses cost about 18% of the account and need a 22% gain to recover. At 10% per trade the same streak costs 65% and needs a 186% gain. The percentage you pick sets how long a bad run you can survive without changing anything else.

Pips or a stop price?

Both work. A pip distance is faster when you size off a fixed stop; a stop price is safer when the level comes from structure, because the calculator derives the distance instead of you doing it in your head at the wrong moment.

The result is below my broker's minimum lot

Then the trade as specified cannot be taken at that risk. Either widen the account, tighten the stop, or accept a larger risk percentage — deliberately. Rounding a 0.004 result up to 0.01 silently multiplies your intended risk.
