What is 18k Gold?

Gold purity is measured in karats (k). Pure gold is 24k, meaning it contains 100% gold with no other metals. However, pure gold is soft and not practical for making durable jewelry. That’s why gold is often mixed with other metals such as copper, silver, or nickel.

18k gold means it is 75% pure gold and 25% alloy metals.
It is stronger than 24k gold, making it popular for rings, bracelets, and necklaces.
It still maintains a rich golden color while being durable enough for everyday wear.

Because it’s not pure, 18k gold is always less valuable than 24k gold of the same weight. This is why a tool like the 18k Gold Calculator is so useful.

How Does the 18k Gold Calculator Work?

Our tool is designed to give you accurate values instantly. It calculates two things:

Pure Gold Value (24k):
This is the value of your gold if it were 100% pure.
Formula: Pure Value = Weight (grams) × Rate per gram
18k Gold Value:
Since 18k gold is only 75% pure, its value is adjusted.
Formula: 18k Value = Pure Value × (18 / 24)

By using these formulas, you can clearly see the difference between pure gold and 18k gold worth.

How to Use the 18k Gold Calculator

Using our calculator is simple and requires just two inputs:

Example Calculation

Let’s say you have a gold chain weighing 10 grams, and today’s gold rate is $60 per gram.

Pure Value = 10 × 60 = $600
18k Value = 600 × (18/24) = 600 × 0.75 = $450

So, your 10g 18k gold chain is worth $450 based on the given gold rate.
