XAUUSD calculator
1 standard lot of XAUUSD is 100 ounces, so every $1 move in gold is worth $100 per lot ($1 per 0.01 lot). Lot size, value of a move, profit or loss, margin and spread cost for gold CFDs and COMEX gold futures. All maths in USD.
Profit / loss
-
Value of a $1 move
-
Value of a $0.01 move (one point at 2 decimals)
-
Value of a $0.10 move (a "pip" at many brokers)
-
Cost to open and close (spread + commission)
-
Margin to open
-
Futures margin is set by CME and your broker, not by leverage; COMEX GC and MGC tick size is $0.10 ($10 and $1 per contract).
Formulas
- Profit or loss = (exit - entry) × ounces per lot × lots (negative for a short when price rises).
- Value of a $1 move = ounces per lot × lots. One standard XAUUSD lot of 100 oz: $100 per $1, $1 per $0.01.
- Spread cost = spread per ounce × ounces per lot × lots. A $0.25 spread on 1 lot costs $25.
- CFD margin = price × ounces per lot × lots / leverage.
"Pip" means different things at different brokers: $0.10 at many, $0.01 at some. Check your broker's contract specification. Spreads change through the day - see market hours. · How we measure
Questions
How many ounces are in 1 lot of gold (XAUUSD)?
At most CFD brokers 1 standard lot of XAUUSD is 100 troy ounces, so 0.01 lot is 1 ounce. COMEX gold futures (GC) are also 100 ounces; micro gold futures (MGC) are 10 ounces. Check your broker's contract size.
How much is a $1 move in gold worth?
$100 per 1 lot of 100 ounces, $10 per 0.1 lot and $1 per 0.01 lot.
What is a pip in XAUUSD?
There is no single definition: most brokers call $0.10 a pip (worth $10 per 1 lot), some call $0.01 a pip (worth $1 per 1 lot). The calculator shows both.
What lot size should I use for gold?
Work back from the loss you accept: lots = loss in $ / (stop distance in $ x ounces per lot). A $10 stop with $100 at risk on 100-ounce lots is 0.1 lot.
How much margin do I need for 1 lot of gold?
Margin = price x contract size / leverage. At a gold price of $4,000 and 1:100 leverage, 1 lot of 100 ounces needs $4,000 of margin; at 1:500 it needs $800.
