Helpful answers
Gold Value Calculator FAQ
What is gold melt value?
Gold melt value is the theoretical value of the gold content in an item at the stated spot reference after applying its weight and purity. It excludes craftsmanship, premiums, taxes, testing, fees, and a buyer's margin.
What formula does the calculator use?
It converts the selected weight into grams, multiplies by spot price per gram, applies the selected purity factor, and converts the result into the chosen currency.
Does the result include a dealer’s margin?
No. The result is a theoretical spot / melt value estimate and does not include dealer spreads, jewellery premiums, taxes, assay fees, refining costs, or a buyback margin.
Which purity options are supported?
The calculator supports 24K, 22K, 18K, 14K, 10K, and 9K theoretical purity factors.
Why can the calculator result change later?
The tool uses the latest valid server-side spot and foreign-exchange references available at the time of the request. Provider updates, delayed data, or a stale fallback can change the displayed estimate.
