How gold value is calculated
Weigh the item. Jewellery scales read grams; if yours shows ounces, remember a troy ounce is 31.1034768 g.
Identify the karat from the hallmark — 24k (.999) bullion, 22k/18k/14k jewellery. The karat fixes the fineness factor (0.999 / 0.9167 / 0.750 / 0.5833).
Multiply weight by the live per-gram price for that karat — exactly what this calculator does from the current spot reading.
Compare against any offer you receive. Buyers should reference melt value; knowing it is your negotiating baseline.
Melt value vs what you pay
The calculator returns melt value — the intrinsic metal worth. Retail jewellery sells at melt plus making charges, design premium and local taxes (often 20–40% above melt). Scrap buyers purchase at melt minus their margin (typically paying 60–90% of melt). The melt number is the honest anchor both sides negotiate around.
Frequently asked questions
How is the value of gold calculated?
Gold value = weight in grams × the live per-gram price for your karat. The per-gram price itself comes from the global spot price: spot ÷ 31.1034768 grams per troy ounce × the karat’s fineness (24k = 0.999, 22k = 0.9167, 18k = 0.750, 14k = 0.5833).
What is my gold worth right now?
Right now 24k gold is worth $147.18 per gram — enter your item’s weight and karat above and the calculator applies the live price instantly. The figure updates every minute with the market.
Is this the resale value of my jewellery?
It is the melt value — the metal content. When selling, expect buyers to offer a percentage of this figure (use our scrap calculator for realistic payouts). When buying new jewellery, expect to pay melt plus making charges and tax.
Which karat should I choose?
Check the hallmark: western jewellery is usually stamped 14k or 18k, British pieces may show 9k/18k/22k, and bullion is 24k (.999). If unknown, 18k is the most common assumption — but verifying the stamp changes the value significantly.
Why does the calculated value change?
The gold market trades nearly 24 hours a day, so the spot price — and therefore every derived value — moves continuously. We recompute from the live spot every minute and show the exact timestamp used.
