Use this free gold calculator to find the melt value of your gold jewelry, coins, or scrap. Enter the weight and karat purity to get an instant estimate based on today's live gold spot price. The calculator supports all karat levels from 8K to 24K and fifteen units of weight including grams, troy ounces, tola, tael, bhari, mesghal, and pennyweight.
The result shown is the melt value — the raw market value of the pure gold contained in your item. When selling scrap or jewelry, reputable dealers typically pay 70–90% of this figure. When buying from a retail jeweler, expect a premium above melt to cover craftsmanship, brand, and retail margin. The deal checker above compares any offered price against the calculated melt value so you can see at a glance whether a quote is reasonable.
Karat is a measure of gold purity expressed in twenty-fourths. Pure gold is 24 karat, meaning 24 out of 24 parts are gold. Lower karats are alloyed with other metals (usually copper, silver, nickel, or palladium) to improve durability or change color.
The melt value formula is straightforward: Weight × Purity × Spot price per gram. Spot price is quoted per troy ounce (31.1035 grams), so the calculator divides by that first. For example, ten grams of 14K gold at a spot price of $4,686 per ounce works out to 10 × 0.5833 × ($4,686 ÷ 31.1035), or roughly $878.
Weight conversions are handled automatically. A tola is 11.6638 grams, a tael is 37.4290 grams, a pennyweight is 1.5552 grams, and a mesghal is 4.6083 grams. Whatever unit you enter, the calculator normalizes it to grams before multiplying.
How is gold value calculated?
Gold value = Weight × Purity × Spot Price. For example, 10 grams of 14K gold (58.33% pure) at $4,686 per troy ounce = 10 × 0.5833 × ($4,686 ÷ 31.1035) = approximately $878 USD.
What percentage should a dealer pay for my gold?
Reputable dealers pay 70–90% of melt value. Getting 85%+ is excellent. Below 65% means you should shop around. The deal checker above evaluates any offer automatically.
Is 14K or 18K gold better value?
14K (58.3% gold) is more durable and affordable. 18K (75% gold) has higher gold content and is standard in Europe and the Middle East. For investment, 22K or 24K offers the most gold per gram.
What is the difference between troy ounce and regular ounce?
A troy ounce (31.1035g) is heavier than a regular avoirdupois ounce (28.3495g). Gold, silver, and platinum are always priced in troy ounces. The calculator handles the conversion automatically for all fifteen supported units.
Is the spot price on this page real-time?
The spot price is refreshed from public market data feeds and updated frequently during trading hours. It is close enough for estimating the melt value of your item, but always verify the current market price with a reputable source before making a transaction.
