Position Size Calculator

Account size + risk tolerance → optimal position size + leverage

What is the Position Size Calculator?

The Position Size Calculator works risk-first: given account size, per-trade risk (1–2% recommended) and stop distance, it derives the maximum position you should open.

How do I use the Position Size Calculator?

The correct order: set the stop first (from technical structure), then let the tool size the position — never the reverse. At ≤2% risk per trade, even ten consecutive stops cost only ~18%, keeping the account alive.

What should I watch out for?

Slippage and wicks in fast markets can push real losses past the planned risk, and leverage scales position size, not win rate. Of every tool on this site, this is the one to use before every single trade.
