A position size calculator helps traders determine the correct lot size based on account balance, risk percentage, and stop-loss distance. Proper position size is one of the most important parts of risk management in trading.

Instead of guessing your trade size, this tool ensures that you only risk a fixed percentage of your account on each trade. This helps protect your capital and maintain consistency over time.

Why Position Size Matters
