How does the Position Size Calculator work?
Position Size Calculator computes the position size directly from your inputs — the Account Size, Risk Per Trade, and Entry Price feed the formula. Your numbers stay in the tab and the position size recalculates the moment a field changes.
How the Position Size Calculator works
What separates Position Size Calculator from a bare number is the trail behind it: Account Size, Risk Per Trade, and Entry Price go in, the figure comes out, and the route between the two stays on screen.
Using the Position Size Calculator
- Account Size — one of the values position size builds from; the figure reflects exactly what you type.
- Risk Per Trade — used in the first position size stage, so entering it accurately beats any later refinement.
- Entry Price — read as written by the Finance formula — no scaling, no conversion of the number.
- The result panel on Position Size Calculator updates with every keystroke, so read the result after each change rather than once at the end.
- If a value is a guess, run Position Size Calculator at both ends of its range and quote the pair of position size figures rather than a single prediction.
The formula behind the result
Where the Finance method allows more than one common convention, Position Size Calculator uses the one named on the label and computes the position size with it from the first term to the last.
Worked example: with account size of 10,000, risk per trade of 1, entry price of 50, this position size calculation returns Position Size: 33 shares. The same run reports Risk budget: $100.00 | Per-share risk: $3.00 | Actual dollar risk: $99.00.
The steps it follows:
- Formula: Shares = (Account × risk %) ÷ per-share risk
- Risk budget = $10,000 × 0.01 = $100.00
- Per-share risk = |50 − 47| = $3.00
- $100.00 ÷ $3.00 = 33.33 → floor to 33 shares
Understanding the result
The result is the headline answer from Position Size Calculator; the supporting figures beneath it and the step list give the context needed to judge it.
Where it helps
Position Size Calculator suits settling a question you keep coming back to, swapping one assumption at a time, and seeing whether a quoted number holds up — the kind of question that arrives once a week and deserves a defensible number.
Common mistakes
Comparing a position size result with a quote that uses a different convention is not a like-for-like check, even when both numbers look similar.
Tip: Position Size Calculator returns Position Size: 33 shares at its defaults; double the Account Size ($) and it returns Position Size: 66 shares.
Assumptions and limitations
Treat the result from Position Size Calculator as a planning figure rather than a binding quote, and confirm important decisions with the relevant professional.
Why use this calculator
Because the position size page shows its assumptions rather than burying them, you can see which ones your own case breaks.
