Gold Bar Premium Formula

Fine Gold = Weight × Purity
Spot Metal Value = Fine Gold × Spot ÷ 31.1034768
Premium = Purchase Price − Spot Metal Value
Premium % = Premium ÷ Spot Metal Value × 100

What a Bar Premium Represents

The premium is the price difference between the bar and its calculated underlying metal value. It can incorporate refining, fabrication, assay packaging, dealer inventory, distribution and other commercial costs.

Use Premium With Resale Analysis

A low purchase premium is helpful, but physical-gold economics also depend on how a dealer values the same bar when you eventually sell it. Combine this tool with dealer spread and buy-vs-sell analysis.

Acquisition premium and resale discount are separate variables.
