Position sizing and risk calculator Position sizing and risk calculator

Trading position size calculator

Use the calculator to keep risk per trade consistent and to see how stop distance changes position size.

Markets can gap, fees can vary and execution can slip, so the result should be treated as a planning estimate.

Use the calculator to turn input values into a clear, repeatable result.
Keep units and assumptions visible so the calculation can be checked later.
Copy the result or key numbers for reports, messages or spreadsheets.
Reset to defaults when you want to compare another scenario from a clean state.
Calculators run in the browser and are useful for quick estimates before formal checks.
For finance, health, engineering or legal decisions, verify important results with a specialist or official source.
