Gold & Silver Scrap Metal Calculator UK
Estimate the indicative intrinsic value of gold or silver in GBP from weight and purity. This calculator covers precious metals, not industrial base metals such as copper, brass, aluminium or steel.
Current market referenceGBP valuesNo obligation
The figure is an indicative intrinsic metal value, not a guaranteed purchase offer. Branded, signed, gemstone-set, antique or collectable pieces may be worth more than their metal content.

Understand the number
Spot price, intrinsic value and dealer offers are different
Spot price is a market reference for fine precious metal, commonly quoted per troy ounce. Intrinsic value estimates the pure precious-metal content after applying purity. A dealer offer is a commercial transaction price and can also reflect testing, refining, handling, market risk and margin.
Transparent methodology
How the calculator works
Indicative intrinsic value = weight in grams × precious-metal purity × available fine-metal value per gram
Weights entered as troy ounces are converted using 1 troy oz = 31.1034768g before purity is applied. Read the full precious-metal calculator methodology.
Whole-item value
Could your jewellery be worth more than scrap?
Raw metal value is only one component of value. Signed or branded jewellery, luxury watches, diamond or gemstone-set pieces, antique and period jewellery, unusual craftsmanship, coins and collectable objects can command a premium above intrinsic metal content.

Questions, answered
Frequently asked questions
How is precious-metal scrap value calculated?
Weight is converted to grams where necessary, then multiplied by the selected metal purity and the available fine-metal value per gram.
Is this calculator a purchase offer?
No. It estimates indicative intrinsic precious-metal value only. A specialist valuation can differ after testing and item-specific assessment.
What does a 375, 750 or 925 hallmark mean?
375 means 37.5% gold or 9ct, 750 means 75% gold or 18ct, and 925 means 92.5% silver or Sterling Silver.
Can jewellery be worth more than scrap value?
Yes. Signed, branded, antique, gemstone-set, limited, rare or collectable pieces can be worth materially more as complete items than their raw precious-metal content.
Can I use troy ounces instead of grams?
Yes. Select Troy ounces in the calculator. One troy ounce is exactly 31.1034768 grams.
