Gold Melt Value Calculator
When you are evaluating more than one gold item at a time, a single-row calculator usually is not enough. Our gold melt value calculator is designed for estate lots, jewelry boxes, dealer buy lists, and anyone who needs to total multiple pieces in one session. Add each item with its own description, weight, unit, and karat, and the tool will calculate the melt value for every row plus the combined total. That makes it easier to sort mixed lots, compare categories, and decide whether a buyer’s offer reflects the real gold content. In the U.S. resale market, this is especially useful when you have a mix of 10K, 14K, and 18K jewelry or when some pieces are measured in grams while others are quoted in pennyweight. Instead of doing separate conversions manually, the calculator handles the math for you and produces a clean summary that you can copy or export. If you need an accurate melt value calculator for real-world gold sorting, this page is built for that workflow.

Summary formula
Sum of each item\'s melt value
How it works
Each row is calculated independently so that different karats and weight units can be mixed in the same estimate. This is useful for inherited jewelry, repair scrap, and buying lots from multiple sources.
The calculator converts each weight to troy ounces, applies the karat purity, and multiplies by the live spot price. That creates a per-item melt value that is easy to review line by line.
At the bottom, the tool adds every row together for a combined melt value. You can then export the summary table for negotiation notes, internal records, or a customer quote.
Because the live price field is editable, dealers and advanced users can also simulate different market prices before locking in a buy offer.
Formula
Total melt value = Sum of (Item weight in troy ounces × Item purity × Spot price)
Example calculation
- Row 1: Ring, 8 g, 14K
- Row 2: Chain, 12 dwt, 10K
- Calculate each row separately, then add the two melt values together for a combined estimate
- The export button creates a CSV-friendly summary so you can save the itemized result

Use any label that helps you identify the item later, such as ring, bracelet, chain, dental scrap, or customer lot number.
Can I export the total?
Yes. The export summary action creates a simple CSV-style download of the row data and totals.
Is this only for jewelry?
No. It works for any gold item as long as you know the weight and purity.
