Forex Position Size Calculator

Choose the maximum account amount at risk first. This calculator converts that risk and your stop distance into a mathematical lot size for major USD pairs.

Calculate position size

USD account · major pairs containing USD

Pip size: 0.0001

This is a pre-cost mathematical size, not a recommendation or loss guarantee. Round down to the broker’s supported increment and independently check its order calculator, margin, spread, and gap risk.

Trading tips

Risk amount comes first

The calculator starts with balance × chosen risk percentage. The percentage is your input, not a recommendation.

Use a structural stop

Choose the invalidation point from the chart, then measure the stop in conventional pips. Do not move the stop simply to obtain a larger position.

Add execution costs

Spread, commission, slippage, and gaps can make the realised loss larger than balance × risk percentage.

Round down to broker increments

A broker may impose minimum and step sizes. Round the calculated lot size down and verify the platform’s own loss preview.
