How to calculate melt value
Melt value = weight in grams × purity fraction × (USD spot price per ozt ÷ 31.1034768)
At 14K purity, 10 g contains 5.8333 g of fine gold. Use 31.1034768 g per troy ounce or 1.55517384 g per pennyweight.
Estimated payout = melt value × selected payout percentage.

Frequently asked questions
Can I enter pieces with different karats?
Yes. Add each piece separately and choose its unit and karat. The calculator sums the fine-gold weight after converting every row to grams.
What does an 80% payout mean?
It means the buyer pays 0.80 times the calculated melt value. Compare the result with an offer after fees.
What do stamps like 14K GP, GF, HGE, or GEP mean for melt value?
These marks describe a gold layer, so do not use the standard 14K setting for the whole item. GP (Gold Plated), HGE (Heavy Gold Electroplate), and GEP (Gold Electroplated) indicate a coating that usually has negligible recoverable value on an individual piece. GF (Gold Filled) and RGP (Rolled Gold Plate) indicate a thicker, mechanically bonded layer. A 1/20 14K GF mark means the 14K alloy layer accounts for one twentieth (5%) of the metal weight. RGP can have a different fraction. Refiners may require bulk lots because of processing costs.
Why does a dealer offer less than melt value?
A buyer may deduct refining, testing, shipping or operating costs. Ask for a written net offer with the tested purity and payable weight.
Should I weigh gemstones with the gold?
Use only the weight of the gold alloy. Stones, springs and other non-gold parts can overstate the result.
