💰 Gold Value Calculator
Enter an item's weight, karat, and the current gold spot price to estimate its intrinsic melt value — works in grams, troy ounces, pennyweight, or kilograms.

What is a Gold Value Calculator?
It works out how much the actual gold in a piece is worth. Give it the weight and karat and the current spot price, and it converts to troy ounces, scales by purity, and returns the metal value — the same figure a refiner starts from when quoting scrap gold.
Use it to sanity-check a buy-back offer, compare a chain to its melt value, or ballpark an inheritance. Remember it's the intrinsic value only: craftsmanship, brand, gemstones, and dealer margins all move the real price up or down, so treat this as a guide and confirm with a reputable dealer.
❓ Frequently Asked Questions
How is the gold value calculated?
The tool converts your weight to troy ounces, multiplies by the karat purity (karat ÷ 24), and multiplies by the gold spot price per troy ounce you enter. So a 10 g 18k piece at a $2,000 spot is 0.3215 ozt × 0.75 × $2,000 ≈ $482. It reflects the raw metal (melt) value only.
Does this include the craftsmanship or brand value?
No. It calculates the intrinsic gold content value only. A finished ring, designer piece, or antique can be worth well above melt because of design, brand, gemstones, and condition — and a dealer buying scrap will typically pay below melt to cover refining and margin.
Where do I find the current gold spot price?
Look up 'gold spot price per ounce' from a reputable bullion dealer or financial site — it's quoted per troy ounce in USD (or your currency). Paste that figure into the spot price field. Prices move constantly, so use a live number for an accurate estimate.
What's the difference between karat and fineness?
Karat measures purity in 24ths — 24k is pure gold, 18k is 18/24 (75%), 14k is 14/24 (about 58.3%). Fineness expresses the same purity per thousand, so 18k is 750. Both describe how much actual gold is in the alloy, which is what drives the melt value.
