Gold Spot Price & Bullion Premiums
Physical bullion prices are influenced by the market value of the contained gold and a premium associated with the particular product.
Gold Spot Price
The gold spot price is typically quoted in U.S. dollars per troy ounce and changes with market conditions.
Physical Gold Premium
Premiums reflect fabrication, distribution, inventory, dealer costs, product demand, and availability.
How to Calculate a Gold Bullion Premium
Premium = Purchase Price − Spot Value of Fine Gold
Compare premiums on an equivalent fine-gold basis and account for shipping, taxes where applicable, and other transaction costs.
What Affects the Gold Price?
Gold prices respond to factors including monetary policy, interest rates, currency movements, investor demand, central-bank activity, and global economic uncertainty. Gold can rise or fall in value.
