Gold Assay Value Formula

Fine Gold = Material Weight × Assay %
Gold Price / g = Gold Price / troy oz ÷ 31.1034768
Metal Value = Fine Gold × Gold Price / g

Assay Value Is a Metal Benchmark

It answers “what is the contained gold worth at the entered price?” It does not answer “what will a buyer actually pay?” Refining fees, dealer spreads, taxes and product premiums are separate variables.

Use Representative Assay Data

The value is only as reliable as the assay and the weight measurement. For heterogeneous material, a non-representative sample can create a misleading theoretical value.

This tool performs a mathematical estimate and is not an assay service.
