Gold’s value depends on its carat, its weight in grams and the market rate on the day. Multiply the per-gram rate for your carat by the weight and you have an indicative figure, which is what the calculator below does using GoldPaid’s published rates. Your firm offer depends on inspection, weight, purity, hallmarks, stones, condition and the market rate on the day.
Based on an indicative rate of £1.34/g for Sterling silver (925). Rates last reviewed 2026-08-08.
Send a photo to check this figureThe 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. Asking is free and there is no obligation at any stage.
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.
Why might my written offer differ from this estimate?
Four reasons, and an honest breakdown names which one applied. The weight you typed may have been rounded by kitchen scales; the carat you selected may not be the alloy that was there; stones, clasps, springs, hollow fill and plated parts come out of the payable weight; and the market moves between the day you run an estimate and the day your parcel is examined. All four can push the figure down, and the first, second and fourth can push it up.
