How to calculate
Estimate the theoretical spot-metal value of gold by weight, purity, currency, and a live cached or custom market price.
The selected grade supplies one purity factor. Pure metal weight = entered weight × that grade factor. Estimated value = pure metal weight in troy ounces × selected market price per troy ounce. Purity is never applied a second time.
Worked example
Weight: 1; Weight unit: g; Currency: USD; Live market price / custom price: live; Gold level / karat: 99.9; Custom purity mode (%): 100; Custom market price: 100; Custom price unit: troy_oz.
Estimated metal value: 3.22 USD; 24K Gold Weight: 1 g; Market price per 24K gram: 3.22 USD/g.
Assumptions and limits
This is theoretical contained-metal value, not a retail, jewellery, scrap, or dealer quote. Workmanship, premiums, taxes, assay costs, dealer margins, and local conditions may change a transaction price. Live mode uses only server-cached validated data and never invents a value.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
The result estimates the contained gold value after applying the selected fineness to the entered weight.
When this tool is useful
Compare a known gold weight with a current cached quote or a price you enter yourself.
