Example: Calculating the Value of an 18K Gold Chain

Let’s say you have an 18K gold chain that weighs 20 grams, and the current price of gold is $65 per gram.

  • Gold Purity (18K): 75%
  • Pure Gold Content: 20 g × 0.75 = 15 g
  • Value: 15 g × $65 = $975

Result:
You have 15 grams of pure gold, worth approximately $975.

A karat (K) measures the purity of gold. 24K is 99.9% pure gold, while 18K is 75% pure. The higher the karat, the more gold content it contains.

No, this calculator is designed specifically for weight in grams. You’ll need to convert other units to grams first.

3. Where can I find the current gold price per gram?
Visit financial websites like Kitco, GoldPrice.org, or check your local gold market prices. Ensure you choose price per gram, not per ounce.

4. Does the calculator account for making charges or taxes?
No, this tool only calculates raw gold value based on weight and purity. Making charges, design costs, or GST are not included.
