Position size calculator.

Built for fixed-dollar risk — the way pros teach beginners. Enter your account, your stop, and your levels. We'll show you the size that keeps the loss inside the plan.

Plan the trade

Pure math, runs locally. We don't store anything you type here.

Most experienced traders cap account risk between 0.5% and 2%.

How to read the result

  • Order value is how many units to take. If your platform asks for “quantity” or “contracts”, this is it.
  • Loss stops at is the dollar amount you actually lose if your stop is hit. Match it to your account risk plan.
  • Stop distance is the gap between entry and stop, per unit. The wider it is, the smaller your position must be.
