Gold Calculator

10K vs 14K vs 18K vs 22K vs 24K Gold Value

Karat is the biggest reason two items with the same weight can have very different gold values.

What karat means

Karat tells you how much fine gold is in an alloy. 24K is treated as pure gold, 18K is 75%, 14K is about 58.3%, and 10K is about 41.7%.

Why jewelry uses lower karat

Pure gold is soft, so jewelry is often mixed with other metals for durability, color, and price. The calculator focuses on gold content.

How to compare items

When comparing items, look at both weight and karat. A heavy 10K chain can contain more fine gold than a tiny 18K pendant.
