XAUUSD Pip Value and Lot Size: How Gold Profit and Risk Are Calculated

The short answer

There is no universal cash value for “one pip of gold.” XAUUSD contract size, price digits, minimum tick and tick value can differ by broker. On a common specification where 1.00 lot represents 100 troy ounces, a $0.01 move is $1 for 1.00 lot, $0.10 for 0.10 lot and $0.01 for 0.01 lot. But that example is valid only when your broker shows the same contract size and tick definition.

The reliable method is to open the XAUUSD contract specification in MT4 or MT5 and use its contract size, tick size, tick value, minimum volume and volume step.

Why “pip” is ambiguous for gold

In major forex pairs, traders usually agree that a pip is 0.0001. Gold is quoted as a metal CFD and brokers do not all use the word pip in the same way. One person may call a $0.01 move one pip, another may call a $0.10 move one pip, and the platform itself normally reports points or ticks.

That is why statements such as “100 pips on gold” are incomplete. You still need the entry price, exit price, lot size and broker specification before you can calculate money profit or loss.

The four contract fields that matter

• Contract size: how many ounces or contract units are represented by 1.00 lot.
• Tick size: the smallest permitted price movement.
• Tick value: the cash change for one tick at the stated volume, normally converted into the account currency by the platform.
• Volume step: the increments in which lots may be entered, such as 0.01.

MetaTrader makes these symbol properties available in the instrument specification. The displayed values from your connected broker take priority over a generic online pip table.

XAUUSD profit and loss formula

For a straightforward gold CFD whose profit currency matches the account currency:

Profit or loss = price change × contract size × lots

Assume the following example specification:

• Contract size: 100 ounces per 1.00 lot
• Entry: 2,700.00
• Exit: 2,705.00
• Position: 0.10 lot

The price moved $5.00 per ounce. The result before spread, commission and financing is:

$5.00 × 100 × 0.10 = $50

For a short position, the sign reverses: entry price minus exit price is used to determine the direction of profit or loss.

A practical tick-value table

Under the same example specification—100 ounces per lot and a $0.01 tick—the values are:

• 1.00 lot: a $0.01 move changes P/L by $1.00; a $1 move changes it by $100.
• 0.10 lot: a $0.01 move changes P/L by $0.10; a $1 move changes it by $10.
• 0.01 lot: a $0.01 move changes P/L by $0.01; a $1 move changes it by $1.

Do not copy this table until you confirm the platform reports the same 100-ounce contract and $0.01 tick.

How to calculate XAUUSD lot size from risk

Position size should be calculated backwards from the amount you are prepared to lose at the stop:

Lots = money at risk ÷ (stop distance in price × contract size)

Example:

• Account equity: $10,000
• Chosen risk: 0.5%, or $50
• Entry: 2,700
• Stop: 2,695
• Stop distance: $5 per ounce
• Contract size: 100 ounces

Lots = $50 ÷ ($5 × 100) = 0.10 lot

At 0.10 lot, a $5 adverse move is approximately $50 before spread, commission, swap and slippage.

If the calculated value is 0.106 but the broker accepts 0.01-lot steps, round down to 0.10. Rounding up increases the planned loss.

Why the same gold lot can feel very different from EURUSD

The number printed in the volume box does not measure risk by itself. XAUUSD can move several dollars quickly, spreads can widen around major US data, and its contract specification differs from a currency pair. A trader who routinely uses 0.50 lot on EURUSD should not assume that 0.50 lot on gold creates comparable exposure.

Calculate the cash effect of the stop for each instrument separately. Equal lots are not equal risk.

Five mistakes that cause oversized gold trades

1. Treating a pip and a point as universal units instead of checking tick size.
2. Assuming every broker uses a 100-ounce standard contract.
3. Calculating from leverage or available margin instead of stop-loss risk.
4. Forgetting that spread, commission, swap and slippage can make the realized loss larger.
5. Copying the same raw lot to accounts with different equity, currency or symbol specifications.

Before placing or copying an XAUUSD trade

• Open the XAUUSD symbol specification on every account.
• Record contract size, tick size, tick value, minimum lot and volume step.
• Measure the stop in price terms, not an unexplained number of “pips.”
• Convert the stop into money at the intended volume.
• Add a buffer for spread and slippage.
• Check total gold exposure across all open and copied positions.
• Test symbol mapping if one broker calls it GOLD and another XAUUSD, XAUUSD.a or XAUUSDm.

FAQ

How much is 1 pip on XAUUSD?

It depends on what the speaker means by pip and on the broker's contract specification. If 1.00 lot is 100 ounces and the chosen unit is a $0.01 move, that movement is $1 at 1.00 lot. Confirm both assumptions on the platform.

How much is a $1 gold move at 0.01 lot?

With a 100-ounce contract, 0.01 lot represents one ounce, so a $1 move is approximately $1 before costs. A different contract size produces a different result.

What lot size should I use for gold?

There is no universal answer. Divide your chosen money risk by the stop distance multiplied by contract size, then round down to the permitted volume step.

Why does an online calculator disagree with MT5?

The calculator may assume a different contract size, account currency or tick definition. Check the connected broker's symbol specification and current tick value.

Can I copy the same XAUUSD lot between brokers?

Not safely by default. Symbol names, contract sizes, minimum lots and execution prices may differ. Map the symbols and scale risk for every follower account.
