- pure_grams = weight_grams × purity
- troy_oz = pure_grams × 0.0321507466
- value = troy_oz × spot (spot is $ / oz t)
Calculate the melt value of gold, silver, and platinum by weight and purity — with live spot prices updated every 60 seconds. Free, no signup required.
A melt calculator tells you the intrinsic value of the precious metal in a coin, bar, or piece of jewelry — what it would be worth if melted down and sold at the current spot price. It's the baseline every stacker, jeweler, and coin dealer uses to evaluate whether a price is fair. MetalMetric's free melt calculator supports gold, silver, and platinum with live spot prices refreshed every 60 seconds.
The gold melt value formula is: melt value = weight (g) × purity × 0.0321507 × spot price ($/oz)
For example, a 14k gold ring weighing 5 grams has a purity of 0.585. At a gold spot price of $3,200/oz: 5 × 0.585 × 0.0321507 × 3,200 = $300.78 melt value. The calculator above does this instantly — just enter your weight, select your karat, and get the live result.
Silver melt value works the same way for bars and coins: melt value = weight (g) × purity × 0.0321507 × spot price ($/oz)
For junk silver — pre-1965 US coins — the calculator uses pre-loaded ASW (Actual Silver Weight) multipliers. A 1964 Washington quarter has an ASW of 0.1808 oz, so at $32/oz spot it has a melt value of $5.79. Select "Junk Silver" mode in the calculator above to access all common US silver coin types.
Melt value tells you what your metal is worth. MetalMetric's free vault tracker tells you whether you got a good deal — by comparing your purchase price to the melt value at the time you bought, tracking your premium paid, and showing your live P&L as spot prices move.
