Precious Metal Alloy Value

The Precious Metal Alloy Value calculator computes the raw bullion value for gold, platinum, palladium or silver alloy based on the metal, weight, purity and current spot price.

INSTRUCTIONS: Choose units (e.g. pennyweight or gram) and enter the following:

• (W) Weight of Precious Metal Alloy
• (M) Type of Precious Metal (CHOOSE: gold, platinum, palladium or silver)
• (P)  Percentage of Metal's Purity (e.g 98,5%).  This is a percentage not a karat.

Precious Metal Alloy Value (V):  The raw bullion value is returned in United States dollars (USD).  However, this can be automatically converted to other currencies via the pull-down menu.

The Math / Science

The value of precious metal alloy to a jeweler is the refined value of the metal in the alloy minus the refining fee and the jeweler's fee.  The formula for the Precious Metal Alloy Value is as follows:

           V = SPOT(M) • W • P 

where:

• V is the value of the precious metal alloy
• W is the measured weight or mass of the precious metal
• M is the precious metal (gold, platinum, palladium or silver)
• SPOT(M) is the current spot price of the precious metal
• P is the percent purity of the precious metal
