The short answer
On most trading platforms, 1 standard lot of gold (XAUUSD) = 100 troy ounces. Everything else follows from that:
| Lot size | Ounces | Grams | Value at $4,040/oz | Profit or loss per $1 move |
|---|---|---|---|---|
| 1.00 (standard) | 100 oz | 3,110 g (3.11 kg) | about $404,000 | $100 |
| 0.10 (mini) | 10 oz | 311 g | about $40,400 | $10 |
| 0.01 (micro) | 1 oz | 31.1 g | about $4,040 | $1 |
Gold was trading near $4,040 on 22 October 2026. Check the live XAUUSD price for today’s figure; the ounces, grams and per-$1 amounts don’t change with the price.
Contract sizes vary. A few brokers and account types (cent, micro or “m” accounts) use smaller contracts for XAUUSD. Open the symbol’s specification in your platform and check the “contract size” before you size a trade.
How much is 1 lot of gold in grams and kilograms?
A troy ounce, the unit used for gold, is 31.1035 grams. It is heavier than the everyday ounce (28.35 g).
- 1 lot = 100 oz × 31.1035 = 3,110.35 g ≈ 3.11 kg
- 0.1 lot = 10 oz = 311 g
- 0.01 lot = 1 oz = 31.1 g
For converting the gold price itself into grams, tola or kilograms, see our XAUUSD to price per gram guide.
| Lot size | Troy ounces | Grams | Kilograms | Tola (11.66 g) |
|---|---|---|---|---|
| 1.00 | 100 | 3,110.35 | 3.11 | about 267 |
| 0.50 | 50 | 1,555.17 | 1.56 | about 133 |
| 0.10 | 10 | 311.04 | 0.31 | about 26.7 |
| 0.01 | 1 | 31.10 | 0.03 | about 2.67 |
How much is 1 lot of gold worth?
The value of a position is ounces × gold price. With gold at $4,040:
- 1 lot: 100 × $4,040 = $404,000
- 0.1 lot: 10 × $4,040 = $40,400
- 0.01 lot: 1 × $4,040 = $4,040
That is the notional value: the size of the exposure, not the money you put up. You put up margin (see below), but you gain or lose on the full position.
In other currencies (hypothetical example): at 88 rupees per dollar, 0.01 lot of gold at $4,040 controls about ₹3.56 lakh of gold, and each $1 move is worth about ₹88. Convert using your own rate on the day.
Profit or loss per $1 move, per point and per pip
Because 1 lot is 100 ounces, every $1 move in XAUUSD is worth $100 per lot.
| Gold moves by | 1.00 lot | 0.10 lot | 0.01 lot |
|---|---|---|---|
| $0.10 | $10 | $1 | $0.10 |
| $1 | $100 | $10 | $1 |
| $5 | $500 | $50 | $5 |
| $10 | $1,000 | $100 | $10 |
| $77 (average daily range, Oct 2026) | $7,700 | $770 | $77 |
The words “pip” and “point” are used inconsistently for gold, so thinking in dollars of price movement avoids mistakes. Our XAUUSD pip value guide explains the different conventions, and the gold pip calculator does the maths for any lot size. The $77 average range comes from our gold volatility tracker; see how much does gold move per day for how it changes.
1 lot of XAUUSD vs futures and local contracts
| Product | Size of one contract | Same as |
|---|---|---|
| XAUUSD standard lot (most brokers) | 100 troy oz | — |
| COMEX gold futures (GC) | 100 troy oz | 1.00 lot |
| COMEX micro gold futures (MGC) | 10 troy oz | 0.10 lot |
| CME 1-ounce gold futures (1OZ) | 1 troy oz | 0.01 lot |
| MCX Gold (India) | 1 kg | about 0.32 lot |
Futures have expiry dates, exchange margin and no overnight swap; broker XAUUSD usually has no expiry but charges or pays a swap each night. Check each exchange’s current specifications before trading; the CME Group gold contract page lists the GC terms. The differences are explained in spot gold vs gold futures and what is a gold CFD?
How much margin do you need for 1 lot of gold?
Margin = position value ÷ leverage. With gold at $4,040:
| Lot size | Value | Margin at 1:20 | Margin at 1:100 | Margin at 1:500 |
|---|---|---|---|---|
| 1.00 | $404,000 | $20,200 | $4,040 | $808 |
| 0.10 | $40,400 | $2,020 | $404 | $80.80 |
| 0.01 | $4,040 | $202 | $40.40 | $8.08 |
Leverage limits depend on where you live and your broker: for example, retail gold CFDs are capped at 1:20 in the UK and EU. Use the gold margin calculator for your own numbers.
Margin is not risk. A $8 margin on 0.01 lot doesn’t mean you can only lose $8. Your risk is the distance to your stop-loss multiplied by the dollars per $1 move. If losses eat into your margin, your broker can close positions automatically; the gold margin call and stop-out guide shows how that is calculated.
Worked example: what 1 lot really means for an account
Suppose a trader with $5,000 opens 1.00 lot at 1:500 leverage because the margin is only about $808.
- A $10 move against the position costs $1,000, or 20% of the account.
- A $25 move, about a third of an average day, costs $2,500, half the account.
- A move of roughly $42 would leave less than the $808 margin, and a typical 50% stop-out level would close the trade well before that.
The same trader using 0.05 lots with a $10 stop risks $50, or 1%. Same account, same market, very different outcome.
How to choose the right lot size
Professional traders don’t pick a lot size first. They decide where the idea is wrong (the stop), then size so that stop costs a fixed share of the account:
Lot size = (account × risk %) ÷ (stop distance in $ × 100)
Example: $2,000 account, 1% risk = $20, stop $10 away → $20 ÷ ($10 × 100) = 0.02 lot.
The XAUUSD lot size calculator does this in one step. If even 0.01 lot risks more than 1% of your account with a sensible stop, the account is small for gold: see how much money you need to trade gold.
Common lot-size mistakes
- Assuming every symbol is 100 oz. Check the specification for each symbol and account type.
- Choosing size from available margin. High leverage makes 1 lot affordable to open, not affordable to lose.
- Copying someone else’s lot size. A 0.50 lot trade means something very different on a $100,000 account and a $5,000 one.
- Forgetting costs scale with size too. A $0.30 spread is $30 on 1 lot and $0.30 on 0.01 lot; see XAUUSD spread and swap costs.

Frequently asked questions
How many ounces is 1 lot of gold?
On most platforms, 1 standard lot of XAUUSD is 100 troy ounces. A mini lot (0.1) is 10 ounces and a micro lot (0.01) is 1 ounce. Some brokers use different contract sizes, so check the symbol’s contract specification.
How many grams is 1 lot of gold?
100 troy ounces is 3,110.35 grams, or about 3.11 kilograms, because one troy ounce is 31.1035 grams. A 0.01 lot is one troy ounce, 31.1 grams.
How much is 0.01 lot of gold in dollars?
0.01 lot is 1 troy ounce, so its value equals the gold price. With gold near $4,040, a 0.01 lot position controls about $4,040 of gold, and each $1 move in the price changes your profit or loss by $1.
How much do I make per $1 move on 1 lot of gold?
$100. One lot is 100 ounces, so every $1 change in the gold price changes the position’s value by $100. On 0.1 lot it’s $10 and on 0.01 lot it’s $1.
How much margin do I need for 1 lot of gold?
Margin = position value ÷ leverage. With gold at $4,040, one lot is worth about $404,000, so it needs about $4,040 of margin at 1:100 or $808 at 1:500. Margin is not your risk: your risk is set by the distance to your stop-loss.
Is 1 lot of gold the same at every broker?
No. 100 ounces is the most common size for XAUUSD, but some brokers and account types (for example cent or micro accounts) use smaller contracts. Always read the contract size in your platform’s symbol specification before trading.
How many tola is 1 lot of gold?
One tola is about 11.66 grams, so 1 lot (3,110.35 g) is about 267 tola, 0.1 lot is about 26.7 tola and 0.01 lot (31.1 g) is about 2.67 tola.
Is 1 lot of XAUUSD the same as one COMEX gold futures contract?
In size, yes: both are 100 troy ounces. But they are different products. A COMEX contract (GC) is exchange-traded with an expiry date and exchange margin; XAUUSD at a broker is usually a spot contract or CFD with no expiry and an overnight swap. CME also lists 10-ounce and 1-ounce contracts.
