Use our Gold Calculator to estimate what your scrap gold is worth today. Select a unit (grams, troy ounces, or pennyweight), enter the weight, choose the karat (10k–24k), and the scrap gold calculator returns a live melt-value estimate based on today’s gold price. It works great for jewelry, dental gold, broken chains, and mixed lots.
Melt value = (weight × purity × spot per fine-weight unit)
where purity for 24k/22k/18k/14k/10k = 1.000 / 0.9167 / 0.750 / 0.585 / 0.4167
Tip: Hallmarks help, but only testing (XRF, acid, or fire assay) confirms purity. Mixed-karat lots should be separated for the best accuracy.
The calculator shows theoretical melt value. Buyers subtract costs for refining, handling, and risk. Expect different payout percentages from pawn shops, jewelers, and mail-in services. Get multiple quotes and insist on transparent testing.
