Gold Value Calculator

Melt value is calculated by multiplying the weight in troy ounces by the gold purity (karat/24) and then by the current spot price. For example, 1 troy oz of 14K gold has a melt value of (14/24) x spot price.

Karats (K) measure gold purity — 24K is pure gold, 14K is 58.3% gold. Carats (ct) measure gemstone weight. They are completely different units despite the similar names.

The karat number indicates parts of gold out of 24. 24K is 99.9% pure gold. 18K is 75% gold (18/24). 14K is 58.3% gold (14/24). 10K is 41.7% gold (10/24). Lower karat gold is alloyed with other metals for durability.

No. Melt value is the raw metal value based on weight and purity. Dealers typically pay 85-95% of melt value to cover refining costs and their margin. Numismatic or collectible pieces may be worth more than melt value.

A troy ounce (31.1035 grams) is the standard unit for weighing precious metals. It is slightly heavier than a regular (avoirdupois) ounce (28.3495 grams). All spot prices are quoted per troy ounce.
