The large number at the top is the XAU spot price — what one troy ounce of gold is worth right now in your local currency, refreshed every 5 seconds from market feeds. The session open, high, and low in the metrics strip reset at the New York market open (17:00 ET) each day, so the range you see reflects only today's trading — not yesterday's close.

The change badge (the green or red figure next to the price) shows movement relative to the session open, not the prior day's settle. This matters because gold trades nearly 24 hours: by the time New York opens, London has already been trading for hours, so the "overnight" move is already baked in.

If you watch the XAU spot chart and notice sharp moves at predictable times, they're usually one of three things. 10:30 GMT and 15:00 GMT are the LBMA AM and PM benchmark fixings — the reference rates used by central banks and miners to settle contracts, and they briefly pull the market. 08:30 ET is when major US data prints (CPI, NFP, GDP) hit; these regularly cause 1–2% XAU/USD swings in minutes. And 14:00 ET on FOMC days brings the Fed rate decision, the single most reliably volatile event on the XAU calendar.

The troy ounce (oz) is the global trading standard — every XAU/USD quote you'll see on a Bloomberg terminal, futures exchange, or forex platform uses it. But it's an awkward unit for everyday calculations. Jewellers in India, the Middle East, and Southeast Asia typically price gold per gram; institutional buyers and central banks deal in kilograms or metric tonnes. The unit toggle on XAUS lets you switch instantly — the conversion is exact: 1 troy oz = 31.1035 g = 0.0311035 kg.

One unit to watch: the tola (11.6638 g), the traditional South Asian weight still quoted in Pakistani, Indian, and Bangladeshi gold markets. The Physical Gold Calculator supports tola and Thai baht weights alongside the standard units.

When a jeweller or coin dealer quotes you a "gold price," it's almost always above the XAU spot price — sometimes significantly. The gap is called the premium, and it covers fabrication, dealer margin, and physical delivery costs. Bullion coins like the Gold Sovereign or American Eagle typically carry a 3–8% premium over spot; retail jewellery can be 20–100% over, since you're also paying for craftsmanship.

Gold ETFs like GLD or IAU sit closer to spot but trail it by their expense ratio (typically 0.10–0.40% per year). The XAU spot price shown here is the raw OTC benchmark — what the market says an ounce is worth, before any of those layers are added.

XAU / Gold Spot Price — Common Questions

XAUS detects your approximate location and converts the XAU spot price into your local currency using indicative FX rates. So a user in the UK sees GBP, a user in Japan sees JPY, and so on. The underlying price is always the same global XAU/USD spot rate — only the currency layer changes. You can override this using the currency selector in the top navigation, or explore the four-currency comparison panel to see XAU priced simultaneously in EUR, GBP, JPY, and AUD.

The session high/low resets every trading day at the New York open (17:00 ET) and tracks only today's intraday range — useful for day traders judging whether current prices are near the top or bottom of the day's action. The 52-week high/low shows the widest price range over the past year and gives longer-term context — how today's XAU price compares to where gold has been across the full economic cycle.

XAU is the ISO 4217 code for gold. The "X" prefix is reserved by the standard for supranational units — things that don't belong to any single country's currency system. Gold qualifies because it trades globally with no issuing nation. The "AU" comes from aurum, the Latin word for gold, which is also why Au is gold's symbol on the periodic table. So XAU literally means "supranational aurum."

The 400 troy ounce bar is the London Good Delivery standard — the format in which central banks, the IMF, and the LBMA clearing members hold and trade physical gold at the wholesale level. It's the bar you see stacked in vault photos. At current spot prices, one 400 oz bar is worth roughly $1.3–1.8 million USD. The calculator preset lets you quickly see the current dollar value of a Good Delivery bar, which is a useful reference point for understanding institutional gold holdings.
