Work out the exact lot size so hitting your stop loses only what you choose to risk. Free, instant, and no sign-up needed.
Tip: 1–2% risk per trade is the disciplined range most lasting traders use.
Sizing so a stop-out costs exactly your chosen risk %. Pip value uses your entry price for USD-base pairs.
Your position size is set so that if price hits your stop, you lose exactly the percentage of your account you decided to risk — no more. The formula is simple:
Lot size = (account balance × risk %) ÷ (stop distance in pips × pip value per lot).
First your risk amount in dollars (balance × risk %). Then the distance from entry to stop in pips. Divide the dollar risk by the dollar value of those pips for one standard lot, and you have the lot size that keeps every loss the same controlled size. Consistent, small, fixed risk is the single habit that separates traders who last from those who blow up.
How do you calculate forex position size?
Position size = (account balance × risk %) ÷ (stop distance in pips × pip value per lot). It sets your lot size so hitting your stop loses exactly your chosen risk percentage.
What risk per trade should I use?
Most disciplined traders risk 1–2% of their account per trade. Smaller, constant risk is what separates traders who last from those who blow up.
What is a pip worth?
For pairs quoted in USD such as EUR/USD or GBP/USD, one pip is about $10 per standard lot. For USD/JPY and other USD-base pairs the value depends on the current price, which this calculator handles from your entry.
