Forex Leverage & Margin
Leverage lets you control a large trade with a small deposit, called margin. It makes forex accessible with a small account, but it multiplies losses exactly as much as profits. This is the lesson that decides whether beginners survive.
Risk warning: Leveraged forex and CFD trading is high risk. Regulators in the UK and EU require brokers to publish how many retail accounts lose money, and the figure is typically between about 60% and 80%. You can lose your entire deposit quickly. Only trade money you can afford to lose.
What is Leverage?
Leverage is written as a ratio, such as 1:30 (or 30:1). It means that for every $1 of your own money, you can control up to $30 of currency.
Example
Leverage 1:30 Your deposit (margin): $1,000 Maximum position: $1,000 × 30 = $30,000
Without leverage, $1,000 could only buy $1,000 worth of currency, and a 50-pip move on EUR/USD would earn or lose about $5.
Note: Leverage is not free money and it is not a loan you repay. Your broker simply lets you hold a bigger position, as long as you keep enough margin in the account to cover losses.
What is Margin?
Margin is the amount of your money the broker sets aside as a good-faith deposit while a trade is open. It is not a fee: you get it back when the trade closes (plus or minus your profit or loss).
Example: 1 standard lot of EUR/USD at 1.0850
Position value = 100,000 € × 1.0850 = $108,500
| Leverage | Margin % | Margin required |
|---|---|---|
| 1:30 (EU, UK, Australia) | 3.33% | $3,616.67 |
| 1:50 (US) | 2% | $2,170.00 |
| 1:100 | 1% | $1,085.00 |
| 1:500 (offshore) | 0.2% | $217.00 |
When the base currency is your account currency (USD/JPY, USD/CAD, USD/CHF for a USD account), the position value is simply the number of units: 1 standard lot = $100,000, so at 1:30 the margin is $3,333.33.
Balance, Equity, Used and Free Margin
Your platform shows several numbers. Learn them now:
| Term | Meaning | Formula |
|---|---|---|
| Balance | Cash in the account, from closed trades only | Deposits + closed P/L |
| Equity | What the account is worth right now | Balance + open (floating) P/L |
| Used margin | Money locked by open trades | Sum of required margin |
| Free margin | Money available for new trades or to absorb losses | Equity − Used margin |
| Margin level | Health of the account | Equity ÷ Used margin × 100% |
Tip: Watch margin level, not balance. Balance does not change until you close a trade, so it can look fine while your equity is collapsing.
Margin Call and Stop Out
As losses grow, equity falls and so does your margin level. Brokers act at two points:
- Margin call: a warning that your margin level has dropped to a set level (often 100%). You can't open new trades, and you should add funds or reduce positions.
- Stop out (margin close-out): the broker automatically closes your trades, starting with the biggest loser, to stop your account going negative. In the EU, UK and Australia, this must happen by a 50% margin level for retail clients.
Warning: Margin call and stop-out levels differ between brokers. Check yours in the account terms. In a fast market, a stop out can be filled at a worse price than the trigger level.
Worked Example: A Sensible Trade
Example: $1,000 account, 1:30 leverage, buy 0.10 lot EUR/USD at 1.0850
Position value: 10,000 € × 1.0850 = $10,850 Used margin: $10,850 ÷ 30 = $361.67 Equity: $1,000.00 Free margin: $1,000 − $361.67 = $638.33 Margin level: $1,000 ÷ $361.67 × 100 = 276.5% Price falls 50 pips to 1.0800 (0.10 lot = $1 per pip): Floating loss: −$50 Equity: $950.00 Free margin: $950 − $361.67 = $588.33 Margin level: $950 ÷ $361.67 × 100 = 262.7% Margin call (100%) when equity = $361.67 → loss of $638.33 → about 638 pips against you Stop out (50%) when equity = $180.83 → loss of $819.17 → about 819 pips against you
This trade can survive a big move. But note: an 819-pip loss would still cost you 82% of the account. A stop-loss should close the trade long before that.
Worked Example: Over-Leveraged
Example: $1,000 account, 1:500 leverage, buy 1.00 lot EUR/USD at 1.0850
Position value: 100,000 € × 1.0850 = $108,500 Used margin: $108,500 ÷ 500 = $217.00 Free margin: $1,000 − $217 = $783.00 Margin level: $1,000 ÷ $217 × 100 = 460.8% Pip value: $10 per pip Margin call (100%) when equity = $217.00 → loss of $783.00 → only 78 pips Stop out (50%) when equity = $108.50 → loss of $891.50 → only about 89 pips
EUR/USD often moves 60–100 pips in a single day. A normal day could wipe out almost 90% of this account.
Note: At 1:30 leverage you could not even open this trade: 1 lot needs $3,616.67 of margin. That is exactly why regulators introduced the caps.
Effective Leverage: The Number That Matters
The leverage your broker offers is a maximum. What really matters is how big your positions are compared to your equity. This is your effective leverage.
Example
Sensible trade: $10,850 ÷ $1,000 = 10.85× A 1% move in EUR/USD (~108 pips) = ~10.9% of the account Over-leveraged: $108,500 ÷ $1,000 = 108.5× A 1% move in EUR/USD = ~108.5% of the account (wiped out)
Tip: Size your trades by risk per trade (for example 1% of your account at your stop-loss), not by how much margin is free. See Position Sizing and Risk Management.
Regulatory Leverage Caps
Regulators limit how much leverage brokers can give retail clients. Professional clients can get more, but lose some protections.
| Region (regulator) | Major FX pairs | Minor / exotic FX | Other protections |
|---|---|---|---|
| EU (ESMA rules; e.g. CySEC, BaFin, AMF) | 1:30 | 1:20 | 50% margin close-out, negative balance protection |
| UK (FCA) | 1:30 | 1:20 | 50% margin close-out, negative balance protection |
| Australia (ASIC) | 1:30 | 1:20 | 50% margin close-out, negative balance protection |
| United States (CFTC / NFA) | 1:50 | 1:20 | No CFDs for retail; brokers must be registered with the CFTC and NFA members |
| Offshore / unregulated | 1:500 – 1:2000+ | Varies | Often little or no protection |
Info: Negative balance protection means you cannot lose more than the money in your account, even if the market gaps past your stop out (as in the 2015 Swiss franc shock, see Forex History).
Danger: High leverage offered by offshore brokers is a marketing tool, not a benefit. The more leverage you use, the fewer pips it takes to lose your account. Choose a regulated broker (Choosing a Broker) and use far less leverage than the maximum.
