Gold Price Calculator
Enter a weight and purity to calculate the value at the live spot price.
Value
—
The calculator multiplies the weight by the purity and the live spot price per gram. For example, 10 grams of 18K gold contains 7.5 grams of pure gold.
Set the percentage below 100 to estimate what a buyer may pay (for example 80–95% of melt value), or above 100 to include a dealer premium.
