Gold is one of the most valuable metals in the world. Whether you have old jewelry, coins, or gold bars, knowing their exact value is important before buying or selling. In this guide, we will show you exactly how to calculate the value of your gold at home.
What You Need
To calculate gold value, you need three things:
The weight of your gold (in grams)
The purity of your gold (in karats)
The current live gold price per gram
Understanding Gold Purity (Karats)
Gold purity is measured in karats. Here is a simple breakdown:
24 Karat = 99.9% pure gold
22 Karat = 91.6% pure gold
18 Karat = 75% pure gold
14 Karat = 58.3% pure gold
The Formula
The formula to calculate gold value is:
Gold Value = Weight (grams) × Purity (%) × Live Gold Price per gram
For example, if you have 10 grams of 22 karat gold and the live gold price is €55 per gram:
10 × 0.916 × 55 = €503.80
