How gold lot sizes work

Gold is priced in US dollars per troy ounce. On most brokers one standard lot of XAUUSD is 100 ounces, so every $1 change in the gold price moves a 1 lot position by $100.

Formula

Lots = Risk amount / (Stop distance in $ × Ounces per lot)

Example: risking $100 with a $10 stop on a 100 oz contract: 100 / (10 × 100) = 0.10 lots.

Working in dollars of price movement avoids the confusion over what a "pip" is on gold, which differs between brokers and platforms.

What each gold lot is worth

Values for XAUUSD on a 100 oz contract, in US dollars. These do not depend on the gold price.

Lot size Ounces Per $1 move Per pip ($0.10) Per $10 move
0.01 lot 1 oz $1.00 $0.10 $10.00
0.05 lot 5 oz $5.00 $0.50 $50.00
0.1 lot 10 oz $10.00 $1.00 $100.00
0.5 lot 50 oz $50.00 $5.00 $500.00
1 lot 100 oz $100.00 $10.00 $1,000.00

Gold lot size by risk and stop

Lots to trade for a given cash risk and stop distance. On a $10,000 account, $50, $100 and $200 are 0.5%, 1% and 2% risk.

Stop Risk $50 Risk $100 Risk $200
$5 stop 0.10 0.20 0.40
$10 stop 0.05 0.10 0.20
$20 stop 0.02 0.05 0.10
$30 stop 0.01 0.03 0.06

Rounded down to two decimals. A result of 0.00 means the stop is too wide for that risk at the smallest lot most brokers allow (0.01).

Frequently asked questions

How much is 1 lot of gold?

On most brokers one standard lot of XAUUSD is 100 troy ounces. Each $1 change in the gold price is worth $100 on 1 lot, $10 on 0.1 lots and $1 on 0.01 lots. Some brokers use 10 oz or 1 oz contracts, so check your contract specification.

What is a pip in gold?

There is no single standard. Most MT4 and MT5 brokers quote gold to two decimals and treat $0.10 as one pip, which makes a pip worth $10 on 1 lot. Others call $0.01 a pip, or $1. That is why this calculator works in dollars of price movement and lets you pick the pip definition.

How much is 0.01 lot of gold worth?

A 0.01 lot is 1 ounce on a 100 oz contract. It gains or loses $1 for every $1 the gold price moves, or $0.10 per pip if your broker counts $0.10 as a pip.

How do I calculate lot size for gold?

Divide your cash risk by your stop distance in dollars multiplied by the ounces per lot. Risking $100 with a $10 stop on a 100 oz contract is 100 / (10 × 100) = 0.10 lots.

What leverage can I use on gold in the UK?

UK retail clients are limited to 1:20 on gold under FCA rules, which means 5% margin. At a gold price of $4,118, one lot is a $411,757 position, so it needs $20,588 of margin at 1:20.
