Long major-pair setup

1.2% risk with a 50-pip stop

A clean planning example for traders who size from account risk instead of intuition.

Result: Position sizing stays disciplined because the lot size is derived from a fixed dollar risk, not conviction.

How the FX sizing model works

The calculator converts your account-risk percentage into a dollar risk amount, then divides that risk by the distance from entry to stop loss to determine how many units you can trade.

That same position size is used to estimate pip value and the reward at your take-profit level, which makes the risk-reward ratio easy to compare before placing the trade.

Forex trading FAQs

How the position size is calculated and what the simplified pip-value model assumes.

What assumption does pip value use here?

This simplified model assumes your account currency matches the quote currency, which makes pip value equal to position size multiplied by pip size. Real broker conversion can differ if the pair or account currency is different.

Does this include spread, swap, or commissions?

No. It is a position-sizing and trade-structure calculator, not a full broker statement model. Those costs can reduce realized reward and should be added separately.
