How we calculate
We do not collect dealers’ prices. Every figure is worked out from the world price, the same way, on every page.
world price per troy ounce÷grams in an ounce×dollar rate×purity×grams in the unit
- World priceSpot gold in US dollars from an aggregated feed 1, recalculated every 10 minutes while the market is open.
- RateThe ZAR rate from central-bank reference data 2. It is a market reference rate, not an official fixing of your central bank.
- Purity and weightFixed constants with their source: see the unit pages. 22k counts as 916 parts gold in 1000.
- WeekendsNo trading, no recalculation: the last price before the close stays, marked “market closed”.
- HistoryThe history and the chart use one series only: daily reference fixings, converted at the rate of the same day. We never join them to the live figure.
Why a jeweller’s price is different
Shops add a making charge and their margin, and buy back for less than they sell. Our figure is the metal alone: the floor of a fair price, not the shop price.
