XAUUSD margin is the deposit a broker holds to keep a leveraged gold position open. It equals the position's value multiplied by the margin percentage. One standard lot of gold is 100 ounces. At a gold price of $4,000, that is $400,000 of exposure. A 5% margin rate holds $20,000. A 1% rate holds $4,000.
The percentage depends on the broker, the regulator and the account type. This guide shows how to calculate it, what changes it, and what happens when an account runs short.
TL;DR
- Margin = lot size × contract size × price × margin rate. For gold, one lot is usually 100 ounces.
- Regulated retail accounts in the UK, EU and Australia cap gold leverage at 20:1, which means a 5% margin rate. Other regions allow more.
- Margin is not the cost of the trade. It is collateral. Losses come out of the same equity.
- Keep free margin well above zero. A margin call or stop-out closes positions at the worst time.
- Copy trading does not remove margin. The copied positions still use margin on your account.

What margin means on a gold trade
Margin is collateral. The broker locks part of your balance while a trade is open. In return, you control a position larger than your balance. Leverage is the ratio between the two. Margin is the deposit that leverage requires.
Two terms matter every day:
- Used margin: the collateral locked by open trades.
- Free margin: equity minus used margin. This is what remains to absorb losses and open new trades.
Margin is not a fee. The broker returns it when the trade closes. Floating losses reduce your equity while the trade is open, so a large margin lock leaves less room for price movement.
The margin formula for XAUUSD
The calculation has four inputs:
Required margin = lot size × contract size × price ÷ leverage
It can also be written as exposure × margin rate. Leverage of 1:100 and a margin rate of 1% are the same thing.
- Lot size: the volume you choose, such as 1.00, 0.10 or 0.01.
- Contract size: for gold, usually 100 ounces per standard lot. Confirm this in your platform's contract specification.
- Price: the current XAUUSD quote, in US dollars per ounce.
- Leverage or margin rate: set by the broker within regulatory limits.
Some brokers use tiered margin. The rate rises as total exposure grows. A small position may use 1%, while a very large one may use a higher rate on the upper tiers. Check the tier table on your broker's specification page before sizing a large trade.
Worked examples
The figures below assume a gold price of $4,000 per ounce. This is an illustration, not a quote. Replace it with the live price.
| Lot size | Ounces | Exposure | Margin at 1:20 (5%) | Margin at 1:100 (1%) | Margin at 1:500 (0.2%) |
|---|---|---|---|---|---|
| 1.00 | 100 | $400,000 | $20,000 | $4,000 | $800 |
| 0.10 | 10 | $40,000 | $2,000 | $400 | $80 |
| 0.01 | 1 | $4,000 | $200 | $40 | $8 |
Two points follow from the table.
First, margin scales with price. If gold rises from $4,000 to $4,400, the same 1.00 lot at 1:100 needs $4,400 instead of $4,000. Open positions use more margin as the price rises.
Second, low margin does not mean low risk. A $1 move in gold changes a 1.00 lot by $100. A $20 move changes it by $2,000. On a $4,000 margin deposit at 1:100, that is half the deposit gone on a move of roughly half a percent of the price. Our pip calculation guide for XAUUSD shows how pip value maps to dollars per lot.
How much capital you need beyond margin
The margin figure is the minimum to open the trade. It is not the amount to fund the account with.
A practical way to size the account:
- Calculate the margin for the lot size you want.
- Decide how far gold could move against you before you would exit. Convert that to dollars per lot.
- Add the two. The account should hold at least that much, with a buffer for spread, slippage and overnight swap.
Example: a 0.10 lot at 1:100 needs $400 of margin. If you accept a $30 adverse move, the loss is $300 on that position (10 ounces × $30). The account then needs more than $700 just to hold the trade to that point, and more to stay safe. Using the full balance as margin leaves no room at all.
Costs add to this. Spread is paid on entry, and swap accrues overnight. We cover those in the guides on XAUUSD spread impact and swap costs on gold. Fills during fast markets can differ from the quote, as the slippage audit for XAU/USD explains.
Margin call and stop-out
Brokers monitor margin level:
Margin level = equity ÷ used margin × 100
Two thresholds apply, and both are set by the broker:
- Margin call level: a warning. The broker may ask you to deposit funds or close positions. Some brokers cannot warn in advance in fast markets.
- Stop-out level: the broker closes positions automatically. Many brokers close the largest losing trade first and repeat until the margin level recovers.
Example with a 50% stop-out. You hold a 1.00 lot at 1:100, so used margin is $4,000. The stop-out triggers when equity falls to $2,000. If your account started at $5,000, a floating loss of $3,000 brings you there. That is a $30 move against a 1.00 lot. Gold has moved that far within a single session.
A stop-out locks in the loss. It also removes any chance of recovery if price turns back. The only reliable defence is a position small enough that a normal gold swing does not threaten the margin level. Our guide to gold leverage and safe exposure covers sizing, and the piece on XAUUSD leverage risks covers what happens when leverage is stretched.
How country and broker rules change the number
The same trade needs different margin depending on where the account is regulated.
| Jurisdiction | Typical retail gold leverage | Margin rate |
|---|---|---|
| UK (FCA), EU, Australia | 20:1 | 5% |
| Mauritius, South Africa | up to 50:1 | 2% |
These figures come from a regulator-by-regulator comparison of CFD leverage limits. Offshore brokers may offer 1:100, 1:500 or more. Professional-client status can also unlock higher leverage in some regions. Higher leverage lowers the margin needed, and it raises the chance of a stop-out on a small move. Rules change, so confirm the current limit with the regulator or the broker.
US readers should note one point. Retail CFDs are not offered to US residents. US traders who want gold exposure usually use futures, spot metal products or physical gold. XAUUSD as a leveraged CFD is mostly a non-US market. Check that a broker is permitted to serve you before you deposit.
Many regulated brokers also apply negative balance protection, so retail clients cannot lose more than the deposit. The scope differs by broker. Read what negative balance protection covers and what it does not before you rely on it.
CFD margin versus gold futures margin
The two products work differently.
| XAUUSD CFD or spot margin | Gold futures | |
|---|---|---|
| Margin set by | The broker, within regulator limits | The exchange clearinghouse, then the futures broker |
| Format | A percentage of position value | A fixed dollar amount per contract, revised by the exchange |
| Contract size | Chosen by lot; micro sizes exist | One standard contract is 100 ounces |
| Calls | Margin call and stop-out levels | Initial and maintenance margin |
| Smallest position | Often 0.01 lot (1 ounce) | Larger, unless micro contracts are used |
Futures have two levels. Initial margin opens the position. Maintenance margin is the floor. If equity falls below it, you must top up to the initial level. Exchanges raise and lower these amounts as volatility changes, so published numbers date quickly. Look up the current exchange margin schedule instead of relying on an old article.
For most traders sizing a small account, the CFD or spot route gives finer position sizes. The futures route has fixed contract sizes and a different regulatory setup.
Controlling margin use in practice
A few habits keep margin from becoming the thing that ends a trade.
- Cap used margin. Many traders keep it to a small share of equity, for example 10% to 20%. Pick your own limit and write it down.
- Size from the stop, not from the margin. Decide the dollar risk first. Work back to the lot size. Then check the margin.
- Watch the calendar. Gold moves hard around US data and central bank decisions. Our volatility strategy for XAUUSD covers timing and ATR-based stops.
- Do not add to losers. Adding lots uses more margin as equity falls. The margin level drops twice.
- Set an equity floor. A fixed drawdown limit closes positions before the broker does. See the equity protection rules for copiers.
The lot size examples in 3 XAUUSD lot size examples show how these limits translate to real volumes. Position sizing also links to broader risk control. A guide to forex risk management for retail traders explains how leverage affects position size and the margin needed to open and hold a trade.
Our perspective
Most margin problems we see are sizing problems, not margin-rate problems. Traders compare 1:100 with 1:500 and pick by the lowest deposit. Then they size the lot to use most of the free margin. A normal gold swing ends the trade.
Sonic AI trades only gold, so margin is central to how the strategy is built. Sonic AI reports a win rate of about 80%, drawdown under 1% and 18 consecutive winning months, with results published on MyFXBook. These are the client's own reported figures, and past results do not guarantee future ones. We still tell users the same thing: the strategy's drawdown is measured on its own account setup, and your result depends on your account size, broker conditions and leverage.
The amplified accounts, 12X and 24X, raise exposure relative to deposit. Higher exposure means higher margin use and a smaller buffer against an adverse move. Read the terms on the amplified account page before choosing one, and fund the account so that margin level stays comfortable.
Our view is simple. Know the margin your position needs. Know your stop-out level. Keep free margin large. Treat any leverage setting as a risk decision.

Copy trading and margin
A copied trade is a real trade on your account. The broker locks margin for it just as for a manual trade. With a copy service, the provider chooses entries and exits. You choose the account size and how much of your equity is exposed.
Sonic AI uses COPYX to copy trades automatically to the connected account, so no manual order entry is needed. The setup guides explain account funding and connection. To see how the strategy has performed, review the Sonic AI MyFXBook results and the live performance page. To start, go to Sonic AI. Fee terms are on the performance fee page. Gold trading carries risk of loss, including loss of the funds you deposit.
FAQ
How much capital do you need to trade XAUUSD?
It depends on lot size and leverage. A 0.01 lot (one ounce) at 1:100 needs roughly $40 of margin when gold trades near $4,000. The margin is only the entry cost. Hold a buffer for adverse moves, spread and swap, or a small swing can stop you out.
Is 1:30 or 1:100 leverage better for gold?
Neither is better by default. Lower leverage needs more margin per lot, so the same account holds a smaller position and has a wider buffer. Higher leverage needs less margin, but it makes oversizing easier. Choose the leverage that lets you size from your stop, not from your free margin.
Are gold margin requirements the same at every broker?
No. Each broker sets its own rates within the limits of its regulator. UK, EU and Australian retail accounts are capped at 20:1 on gold, while some regions allow 50:1 or more. Check the contract specification in your platform.
What happens if my margin level drops too low?
The broker may issue a margin call, then close positions automatically at the stop-out level. Many close the biggest losing trade first. The thresholds are broker-specific, so read them before you trade.
