Based on an indicative rate of £76.14/g for 18ct gold (750). Rates last reviewed 2026-05-14.
The figure above assumes the carat and weight you entered are exact. In practice, items differ from their hallmarks and a calculator cannot account for solder, repairs, stones or non-gold parts. Treat it as a ballpark, then send a photo on WhatsApp for a closer quick indicative figure, or read how we value gold.
How to weigh your items
- Use a digital kitchen or jewellery scale that reads to 0.1g or finer
- Weigh each carat separately, do not mix 9ct and 18ct in one figure
- Remove obvious non-gold parts (such as a steel watch strap) where you can
- If you cannot weigh it accurately, that is fine. Send a photo and we will guide you
Common questions
Is the calculator figure what GoldPaid will pay me?
No. It is an indicative estimate only, based on the site’s published per-gram rates and the weight you enter. Your firm offer is set after an XRF assay confirms the actual purity and weight of your specific items.
Where do the per-gram rates come from?
They are GoldPaid’s own published indicative rates by carat and silver standard. Precious-metal prices move continuously, so the rates, and therefore the estimate, are a guide that changes with the market.
Why can a calculator not give a firm price?
Because real items differ from their hallmarks, solder, repairs and mixed alloys all change the true metal content. A calculator works from an assumed purity; only an XRF assay confirms what is actually there.
