Leverage in forex explained: margin, free margin, margin level and how to use a margin calculator

Leverage lets you open a forex position that is much larger than the money in your account. Instead of paying the full value of the trade, you set aside a small deposit called margin, and your broker lets you control the rest. Leverage in forex is one of the first things new traders notice – and one of the most misunderstood.

This guide explains how forex leverage works, what margin in forex means, how to use a forex margin calculator, and how free margin, margin level and a margin call fit together. Every example uses simple maths, and you can check the numbers yourself on Xellion's free margin calculator.

What is leverage in forex?

Leverage is shown as a ratio, such as 1:100, 1:500 or 1:2000. It tells you how many times larger your position can be than the margin you put up.

• At 1:100, every $1 of margin controls up to $100 of position.
• At 1:500, every $1 of margin controls up to $500.
• At 1:2000, every $1 of margin controls up to $2,000.

Example: one standard lot of EUR/USD (1.00 lot) is €100,000. At a price of 1.0850 that is worth $108,500. Without leverage you would need $108,500 to open it. With 1:100 leverage you need about $1,085 of margin. With 1:500 you need about $217.

The important point: your profit or loss is still calculated on the full $108,500 position, not on the margin. Leverage makes trading possible with a small deposit, but it does not make the trade smaller. A move of 1 pip on 1.00 lot of EUR/USD is still worth about $10, whatever leverage you use.

Xellion offers forex leverage of up to 1:2000, depending on account and country. Your available leverage is shown in your account details.

What is margin in forex?

Margin in forex is the amount of your own money the broker sets aside (locks) while a trade is open. It is not a fee and it is not spent – it is returned to your available funds when you close the position, adjusted for any profit or loss.

Think of margin as a good-faith deposit. The bigger the position, the more margin is needed. The higher the leverage, the less margin is needed for the same position.

There are a few terms you will see in MT5 and the Xellion app. They are easiest to understand together:

• Balance – What it means: Money in your account, not counting open trades · How it is calculated: Deposits + closed profit − closed losses − withdrawals
• Equity – What it means: What your account is worth right now · How it is calculated: Balance + floating profit/loss of open trades
• Used margin – What it means: Money locked to keep open trades running · How it is calculated: Sum of required margin for each open position
• Free margin – What it means: Money available to open new trades or absorb losses · How it is calculated: Equity − used margin
• Margin level – What it means: Health of your account, as a percentage · How it is calculated: Equity ÷ used margin × 100

Forex margin calculator formula

A forex margin calculator uses one simple formula:

Required margin = (lots × contract size × price) ÷ leverage

• Lots – your trade size, for example 0.10.
• Contract size – 100,000 units for one standard forex lot. For gold (XAU/USD) it is commonly 100 ounces, but always check the contract specification in MT5.
• Price – the current exchange rate, which converts the position into your account currency when USD is the second currency in the pair.
• Leverage – the number on the right of the ratio, for example 100 for 1:100.

Worked example: 0.10 lot EUR/USD at 1.0850

Position value = 0.10 × 100,000 × 1.0850 = $10,850

• 1:50 – Calculation: 10,850 ÷ 50 · Required margin: $217.00
• 1:100 – Calculation: 10,850 ÷ 100 · Required margin: $108.50
• 1:500 – Calculation: 10,850 ÷ 500 · Required margin: $21.70
• 1:1000 – Calculation: 10,850 ÷ 1000 · Required margin: $10.85
• 1:2000 – Calculation: 10,850 ÷ 2000 · Required margin: about $5.43

Notice what changes and what does not. The margin falls from $108.50 to about $5.43 as leverage rises. But the pip value stays at about $1 per pip for 0.10 lot of EUR/USD at every leverage level. A 50-pip move against you costs about $50 whether you used 1:100 or 1:2000.

More examples

• GBP/USD, 0.10 lot at 1.2700, 1:500: 0.10 × 100,000 × 1.2700 ÷ 500 = $25.40
• USD/JPY, 0.10 lot, 1:100: when USD is the first currency, the position value in dollars is simply 0.10 × 100,000 = $10,000, so margin = 10,000 ÷ 100 = $100
• Gold (XAU/USD), 0.01 lot at $3,900, 100-ounce contract: 0.01 × 100 × 3,900 = $3,900. At 1:100 that is $39; at 1:500 it is $7.80; at 1:2000 it is $1.95

Some instruments, such as metals, indices or other CFDs, may have different leverage from forex pairs. The margin calculator and the symbol details in MT5 show the actual figure for your account.

Does higher leverage mean higher risk?

This is the most common question about leverage, and the honest answer is: leverage itself does not change how much you make or lose per pip – lot size does. But high leverage makes it easy to open a lot size that is far too big for your account.

Compare two traders, each with $500:

• Leverage – Trader A: 1:500 · Trader B: 1:500
• Trade – Trader A: 0.02 lot EUR/USD · Trader B: 1.00 lot EUR/USD
• Margin used – Trader A: about $4.34 · Trader B: about $217
• Value of 1 pip – Trader A: about $0.20 · Trader B: about $10
• Loss on a 30-pip move – Trader A: about $6 · Trader B: about $300

Both used the same leverage. Trader A lost about 1% of the account on a normal 30-pip move. Trader B lost about 60%. The difference is the lot size, which high leverage made possible.

So the safe way to think about forex leverage is:

1. Decide how much you are prepared to lose on the trade (many traders use 1–2% of the balance).
2. Set your stop loss distance.
3. Work out the lot size from those two numbers using a position size calculator.
4. Only then check the required margin with the margin calculator.

Never choose the lot size from how much margin you have free. Our guide to forex lot size and pip value walks through this step by step, and the pip calculator gives the pip value for any pair.

Free margin and margin level explained

Free margin and margin level tell you how much room your account has before trouble starts.

Example: one trade, $500 account, 1:500 leverage

You open 0.10 lot EUR/USD at 1.0850. Used margin is $21.70.

• At the start: equity $500, used margin $21.70, free margin $478.30, margin level = 500 ÷ 21.70 × 100 ≈ 2,304%.
• After a 100-pip loss (about $100): equity $400, free margin $378.30, margin level ≈ 1,843%.

The margin level is still very high because the position is small compared with the account.

Example: oversized trade, $500 account, 1:500 leverage

You open 1.00 lot EUR/USD at 1.0850. Used margin is $217.

• At the start: equity $500, free margin $283, margin level ≈ 230%.
• After a 20-pip loss (about $200): equity $300, free margin $83, margin level ≈ 138%.
• After about 28 pips against you: equity falls to about $217, free margin is close to zero and margin level is near 100%.

A move of 28 pips can happen in minutes around a major news release. This is why oversized positions get into trouble so quickly, even when leverage made them look affordable. Check the economic calendar before high-impact events.

What is a margin call and stop-out?

When your margin level falls, two things can happen:

• Margin call – a warning level. Your margin level has dropped to a set percentage and you may not be able to open new trades. It is a signal to add funds, reduce position size or close trades.
• Stop-out – a lower level at which the platform starts closing your open positions automatically, usually the largest losing trade first, to stop the account going further into loss.

Different brokers and account types use different percentages for these levels. The exact margin call and stop-out levels for your Xellion account are listed in the account terms on xellion.com – check them before you trade.

Keep in mind that prices can gap, especially over weekends or around big news, so a position may be closed at a worse price than the stop-out level suggests. Losses can be larger and faster than you expect. The best protection is not to get close to a margin call at all: size every trade from what you are prepared to lose and keep plenty of free margin.

How to choose your leverage

There is no single "best" leverage. A few practical points:

• Higher leverage frees up margin, so you can keep a larger buffer of free margin – but only if you keep lot sizes small.
• Lower leverage forces smaller positions on a small account, which some beginners find a useful brake.
• Your lot size, not your leverage, sets your loss per pip. Keep this in mind whatever ratio you pick.
• Watch your margin level in MT5 under the Trade tab, or in the Xellion app, every time you add a trade.
• Using all free margin – What happens: Small moves trigger a margin call · Better approach: Keep most of your equity as free margin
• Choosing lots from leverage – What happens: Position far too large · Better approach: Size from your stop loss and loss limit
• No stop loss – What happens: Loss grows until stop-out · Better approach: Set a stop on every order
• Too many trades at once – What happens: Used margin adds up · Better approach: Check total exposure, not just one trade
• Ignoring gold contract size – What happens: Margin and pip value surprise you · Better approach: Check symbol details in MT5
