How to Determine Gold Melt Value
Gold value is determined by its mass weight, purity (karats), and the prevailing spot price per troy ounce or gram. Our free gold calculator online helps you estimate the raw melt value of gold jewelry, coins, bullion, and scrap materials. The tool handles multiple units of measure—including grams, troy ounces, pennyweights, tolas, and kilograms—and scales calculations across standard karat ratings from 9k (37.5% pure) to 24k (99.9% pure).
How to Use the Gold Calculator
- Input the weight of your gold item in the Weight field.
- Select the weight unit (e.g. Grams or Ounces) from the dropdown.
- Select the Karat purity of your gold (or input a custom purity percentage).
- Input the current market price of gold (price per unit mass) to calculate current value.
- Review the purity breakdown, pure gold content weight, and final melt value.
