How do I calculate lot size for XAUUSD?

Divide your risk amount by (stop loss distance in dollars x 100). Gold's standard lot is 100 troy ounces, so a $1 price move is worth $100 per lot. Example: risking $200 with a $5 stop loss gives $200 / ($5 x 100) = 0.40 lots.

What is 1 lot of gold (XAUUSD)?

One standard lot of XAUUSD is 100 troy ounces of gold. At a gold price of $3,300, one lot controls $330,000 of notional value. Mini lots (0.10 = 10 oz) and micro lots (0.01 = 1 oz) let smaller accounts trade gold safely.

Why do online calculators give me the wrong lot size for gold?

Usually a pip definition mismatch. Some calculators treat one gold pip as $0.10, others as $0.01 — a 10x difference. A few brokers also use non-standard contract sizes. Enter your stop loss as a dollar distance instead of pips to avoid the problem entirely.

What lot size should I use for gold with a $1,000 account?

At 1% risk ($10) with a $3 stop loss: $10 / ($3 x 100) = 0.03 lots. Most brokers allow 0.01 minimum, so this works. Avoid going above 0.05 lots on a $1,000 account — gold's volatility punishes oversized positions quickly.

How many pips is a $1 move in gold?

With the most common MT4/MT5 convention (1 pip = $0.01), a $1.00 move is 100 pips. With the $0.10 convention it is 10 pips. Always check which convention your broker and calculator use — or just work in dollars.

What pip value does gold have per standard lot?

Using the 0.01 convention, one pip is worth $1 per standard lot. Using the 0.10 convention, one pip is $10 per lot. Per full $1.00 of price movement, one standard lot gains or loses $100.

Is gold riskier to trade than forex pairs?

Gold moves more in dollar terms. Daily ranges of $20-40 are common, equivalent to 200-400 forex pips of movement. The same position sizing rules apply, but stops need to be wider and lot sizes correspondingly smaller than what you would use on EUR/USD.

What lot size do gold EAs use?

Well-built gold EAs calculate lot size from account equity and stop distance on every trade, the same formula this calculator uses. Be cautious with EAs that use fixed lots or martingale sizing on gold — its volatility makes recovery grids especially dangerous.

Why Gold Position Sizing Is Different

A standard lot of XAUUSD is 100 troy ounces, not the 100,000 currency units used in forex. That single difference breaks the forex lot size formula most traders carry over from EUR/USD — and it is the reason a "50 pip stop" on gold can mean wildly different dollar amounts depending on who you ask.

The math itself is simple once you work in dollars of price movement instead of pips:

Lot Size = Risk Amount ÷ (Stop Distance in $ × 100)

A $1.00 move in the gold price is worth $100 per standard lot (1.00 × 100 oz). So if your account is $10,000, you risk 2% ($200), and your stop loss is $5 away from entry: $200 ÷ ($5 × 100) = 0.40 lots.

The Gold "Pip" Problem: 0.01 vs 0.10 vs $1

Ask three brokers what one pip of gold is and you may get three answers. Unlike EUR/USD, there is no universal pip definition for XAUUSD — and this is the #1 reason traders report that online calculators "give the wrong lot size" for gold.

Convention	1 pip equals	Value per standard lot	Common where
Cent (0.01)	$0.01 price move	$1	Most MT4/MT5 brokers (2-digit quotes)
Dime (0.10)	$0.10 price move	$10	Many calculators & broker spec sheets
Dollar (1.00)	$1.00 price move	$100	How most gold traders actually talk

If a calculator assumes 0.10 while you are thinking in 0.01, your lot size will be off by a factor of 10. The safest habit: ignore pips entirely for gold and enter your stop as a dollar distance. This calculator works either way — the pip field for XAUUSD uses the 0.01 convention, so a $5.00 stop is 500 pips.

Worked Examples

Account	Risk %	Stop distance	Lot size
$1,000	1% ($10)	$3.00	0.03 lots
$5,000	2% ($100)	$8.00	0.12 lots
$10,000	2% ($200)	$5.00	0.40 lots
$100,000 (prop)	0.5% ($500)	$10.00	0.50 lots

Why your numbers might still differ from your broker

Two things to verify in your broker's contract specification before trusting any calculator: the contract size (almost always 100 oz, but a few brokers offer 10 oz mini contracts) and the minimum lot step (usually 0.01). Gold also moves fast — a $20 range in a session is normal — so a stop that looks generous on EUR/USD terms is often too tight for XAUUSD.
