How to Calculate Scrap Gold Value
Our scrap gold calculator online uses a simple formula: multiply the gold's weight (in grams) by its purity fraction, then multiply by the live gold price per gram. The result is the raw melt value — what the gold itself is worth based on today's market price.
Formula
Value = Weight (g) × Purity (%) × Gold Price per Gram
