Position size, pip value, reward and margin for the major forex pairs, sized from your account, risk percent and stop distance.
Not financial advice. This is an educational tool. Pip values, spreads and margin rules differ by broker, and leveraged forex can lose more than you expect. Check every number with your own platform and speak with a licensed financial advisor before trading.
How forex position sizing works
In forex you size a trade by pips (the smallest usual price step), not shares. Decide how much of the account you will risk, measure the distance to your stop in pips, and the calculator finds the lot size where a stop-out costs exactly that amount.
One standard lot is 100,000 units of the base currency. A mini lot is 10,000 and a micro lot is 1,000. The value of one pip depends on the pair, which is why the same stop distance needs a different size on EUR/USD than on USD/JPY.

Stop, with costsTargetHover to read any pip distance
In plain English: the pink block is the distance to your stop and the green block is the distance to your target. The size is set so the pink block costs exactly the dollars you chose to risk. Lots = dollar risk divided by (stop pips x pip value per lot). If the margin needed is a big slice of your account, lower the size or the leverage even when the risk percentage looks small. Costs matter: the spread, any overnight swap and commission all make the stop wider and the target shorter, so the size shrinks to keep your dollar risk the same.

Rating
In plain English: the first table shows how fast risk and margin grow as you size up, and how a run of five stopped trades hurts. The second shows your same trade under different leverage. Higher leverage does not change what you lose at your stop. It only changes how much cash is tied up and how little room you have before the broker closes you out.
