Scrap gold calculator
Find out what your old or broken gold is worth as metal, using today's UK price, and check how good a buyer's offer really is.
How to use it
- Sort your pieces by hallmark: 375 (9ct), 585 (14ct), 750 (18ct), 916 (22ct). How to read a hallmark
- Weigh each group in grams. Kitchen scales that read to 0.1 g are fine for an estimate.
- Enter the weight and purity for each group, and add up the values.
- When you get quotes, put each one in the offer checker to see what share of the metal value it is.
The figures here are the value of the pure metal at today's spot price. Anyone who buys your gold has to melt and refine it and make a margin, so their offer will be below this. Offers vary between buyers, which is why it's worth getting more than one quote and comparing them with the offer checker.

Common questions
How do I work out the scrap value of my gold?
Weigh the gold parts in grams, find the carat from the hallmark, and enter both in the calculator. It multiplies the weight by the gold content and today's price.
Should I include stones when I weigh it?
Only the gold has metal value, so the calculator gives the value of the gold only. If an item has stones or non-gold parts, its gold weight is less than its total weight.
What does the offer percentage mean?
It is the buyer's offer divided by the value of the gold in the item. A higher percentage means more of the metal value is being paid to you.
