What Is a Lot Size Calculator?
It converts a fixed account-risk amount and stop distance into a position size. The goal is consistency: a wider stop produces a smaller position, while a tighter stop produces a larger one for the same planned risk.
Price → pips
The difference between entry and stop is converted using the selected instrument.
Risk ÷ value
Risk amount is divided by stop pips and pip value per lot.
$10,000 account. 1% risk. 50-pip stop.
The planned account risk is $100. If one standard lot is worth $10 per pip, the calculated position is 0.20 lot.

Four Steps Before Position Entry.
Use current broker specifications and the stop price from your actual trading plan. The calculator cannot decide what risk level is suitable for you.
Choose the instrument
Select the Forex pair or XAU/USD Gold contract.
Enter balance and risk
Use your account currency, current balance and chosen risk percentage.
Add entry and stop
The distance between them determines the number of pips at risk.
Review and round down
Use a broker-supported lot increment and avoid exceeding the calculated size.
