Found an old chain, a single earring or a broken bracelet at the bottom of your jewelry box and wondered what it is really worth? Gold is priced by weight and purity, and once you know those two numbers the math is simple. This free little calculator does it for you: enter the weight, choose the karat, add today’s gold price, and it shows the melt value, an estimated payout from a buyer and how much pure gold your piece actually contains.
How the Gold Value Calculator works
Pick the karat stamped on your piece, enter its weight and the current gold price from any trusted source. The calculator turns your weight into grams, multiplies it by the purity of your karat (for example 14K is 58.5% pure gold) and then by the price per gram. That gives you the melt value. Because buyers need to cover refining costs and profit, they usually pay less than melt value, so use the payout slider to see a realistic offer: about 90–95% at a refiner, 70–85% at a gold buyer and often 50–70% at a pawn shop.

Quick gold selling tips
- Check the hallmark. Look for stamps like 585 (14K), 750 (18K) or 916 (22K), often hidden near the clasp or inside a ring band.
- Weigh without stones. Gems, pearls and enamel add weight but not gold, so the result will be too high if they are included.
- Use a precise scale. A kitchen or jewelry scale accurate to 0.1 g is far better than guessing.
- Spot price is not your price. The live market price is what refiners pay for large bars; individual sellers always receive a percentage of it.
- Compare at least three buyers. Offers can differ by 20% or more, so ask each one for their percentage of melt value.
- Consider the design. Signed or vintage pieces from known makers can be worth more than their gold weight, so have them appraised before melting.
