Calculator explained

About the Position Size Calculator

Estimate position size from account balance, risk percentage, stop distance, and point value. This page combines the interactive tool with practical guidance so you can understand both the result and the assumptions behind it.

How the result is calculated

Position size is estimated by dividing the amount you are willing to risk by the loss per unit between entry and stop price.

Practical example

With a $10,000 account and 1% risk, the maximum planned loss is $100. The permitted position size then depends on the stop distance and value per point.

Common mistakes to avoid

Common errors include mixing points with pips, ignoring fees or spread, using the wrong contract size, and choosing a stop distance that does not match the intended market.

How to use the result

Use the output as a planning estimate. Confirm contract specifications, spreads, commissions, minimum order sizes, margin rules, and live prices with your broker before placing a trade.
