How the numbers are calculated
Spot price and daily change
The headline price is the midpoint of the live bid and ask for one troy ounce (31.1034768 g) of pure gold in US dollars. The daily change is measured against the previous New York 5:00 pm close, the market's standard daily cut-off. Gold trades from Sunday 6:00 pm to Friday 5:00 pm New York time; at weekends the site shows Friday's closing price.
Per gram, kilo, karat and local units
Price per gram = price per troy ounce ÷ 31.1034768. Karat prices multiply by the gold content: 22K = 91.6%, 21K = 87.5%, 18K = 75%, 14K = 58.5%, 10K = 41.7%, 9K = 37.5%. Local units use their standard weights: tola 11.6638 g, Thai baht weight 15.244 g (96.5% gold), Hong Kong tael 37.429 g. These are metal values — what the gold content is worth before making charges, dealer margins and taxes.
Country prices
Local prices are spot gold × the current exchange rate. Where a structural duty means local market prices sit well above that — India's 15% import duty, for example — the page shows that estimate separately and labels it. Each country page explains local taxes and was last reviewed on the date shown; rules change, so check with a dealer or tax authority before a large purchase.
Charts, performance and history
Long-term charts, performance figures, seasonality and the history pages use daily closes of COMEX front-month gold futures, which track the spot price closely (futures usually trade slightly above spot). Percentage changes are measured on that same series for consistency. Prices in other currencies multiply each day's close by that day's exchange rate.
"Why gold is moving"
The daily move is split into a US-dollar effect and a gold-specific remainder using the change in the US Dollar Index — the same idea as the Kitco Gold Index. It is an approximation, labelled "Indicative".
