In one line: leverage in forex lets you open a position larger than your deposit by putting up only a fraction of its value as margin. At 30:1 the margin is one-thirtieth (about 3.33%) of the position; at 500:1 it is 0.2%. Leverage does not change how much a pip is worth — it changes how small a deposit can open the position, and therefore how small a move can wipe that deposit out.
What Is Leverage?
Leverage lets you control a large position with a small amount of capital. A 30:1 leverage ratio means $1,000 of margin can open a $30,000 position.
It amplifies both profits and losses, because your profit or loss is calculated on the full $30,000, not on the $1,000 you put up.
Leverage and Margin: The One Formula
Required margin = position size (notional value) ÷ leverage.
- 1 standard lot of EUR/USD at 1.1000 has a notional value of $110,000. At 30:1 the margin is about $3,667; at 100:1, $1,100; at 500:1, $220.
- The pip value does not change with leverage: on a standard lot of EUR/USD one pip is $10 whatever leverage your account has.
That second point is the one most explanations skip. Higher leverage does not make each pip riskier — it lets you open a bigger position than your deposit can absorb.
What "Account Leverage" Means — and Why Effective Leverage Matters More
Account leverage is the maximum your broker allows (for example 30:1 for a retail client in the UK or EU on major currency pairs). Effective leverage is what you are actually using: the total notional value of your open positions divided by your account equity.
Example: with $1,000 equity and a 0.10-lot EUR/USD position at 1.1000 ($11,000 notional), your effective leverage is 11:1 — whether your account allows 30:1 or 500:1. It is effective leverage, not the account setting, that decides how far price can move before your account is in trouble.
A Worked Example: How an Account Gets Wiped
You deposit $1,000 and open 1 standard lot of EUR/USD on an account that allows 100:1. At 1.1000 the required margin is $1,100 — more than your whole deposit, so the order is refused. Drop to 0.9 lots ($99,000 notional, $990 margin) and it opens, leaving just $10 of free margin.
Each pip now moves your equity by $9. Suppose your broker's stop-out level is 50% — Eightcap, for example, lists a margin call at 80% and a stop-out at 50% on its account page (read 30 September 2026). The margin level is equity ÷ used margin, so it falls to 50% when equity drops to about $495. That takes a loss of about $505 — roughly 56 pips. Half the deposit is gone and the position is closed automatically.
The same trade at 0.10 lots would have lost $56 on the same move.
Margin Call vs Stop-Out
A margin call is a warning level: your margin level has fallen far enough that the broker alerts you, and may stop you opening new positions. A stop-out is the level at which the broker starts closing your positions automatically, often beginning with the largest losing one — check your broker's own policy.
For retail CFD clients in the UK and EU, the regulators set a floor: firms must close out positions when equity falls to 50% of the margin required to maintain them. That rule, and why it is not "half your account", is covered in the 50% margin close-out rule.
Leverage is only half of why accounts blow up. The other half is the trader, covered in trading psychology and cognitive biases.
Leverage Limits — Why They Exist
The EU introduced leverage caps for retail CFD clients in 2018 because of the losses high leverage caused retail traders; the UK made equivalent rules permanent in 2019. The caps run from 30:1 on major currency pairs to 2:1 on crypto — see ESMA rules explained and why each instrument gets a different cap.
The arithmetic of the extremes:
- At 30:1, the margin is 3.33% of the position, so a 3.33% move against you costs an amount equal to the margin.
- At 500:1, the margin is 0.2% of the position, so a 0.2% move costs the whole margin.
Offshore entities that offer several hundred to one are covered in 1000:1 and what the extra zeros cost.
What Leverage Should You Use?
There is no single right number, but there is a sound way to choose: decide your risk per trade first, set the stop where the idea is wrong, and size the position so that stop costs your chosen risk. The leverage you end up using is then an output, not a setting.
Our view: keep effective leverage well below your account maximum — many cautious traders stay under 10:1 — and never let the size of the position be decided by the leverage available.

Frequently Asked Questions
What does leverage mean in forex?
It is the ratio between the size of a position and the margin needed to open it. At 30:1, $1,000 of margin opens a $30,000 position.
Does higher leverage mean higher risk?
Not by itself — risk comes from position size. Higher leverage lets you open a larger position for the same deposit, which is why it is so often the route to a wiped account.
Can I lose more than my deposit with leverage?
Retail clients of UK and EU brokers are covered by negative balance protection, which limits losses to the funds in the account. Elsewhere it depends on the broker and entity — see negative balance protection explained.
