Position-size worksheet
Enter account size, risk percent, and stop distance to see the textbook position-size calculation. It explains the math — it is not advice and not a trade signal.

Work out the math
Risk budget for this trade
$1,000.00
1% of $100,000.00.
Position size (units)
50
Risk budget ÷ (stop distance × value per point per unit). Rounds down in practice.
The formula used
units = (account × risk% ÷ 100) ÷ (stop distance × value per point per unit)
This is the standard textbook calculation only. It ignores leverage, spread, commission, slippage, instrument contract specifications, and any prop-firm rules or lot-size limits. “Value per point per unit” depends entirely on the instrument you trade. Nothing here is a recommendation to take any trade.

Comparing firms next?
Understanding position sizing helps you read a firm’s risk rules, but it is not a recommendation to trade. Compare the firms’ actual risk rules side by side before deciding.
