Gold Cost-per-Gram Formula

Effective Cost = Purchase Price + Additional Costs
Gross $/g = Effective Cost ÷ Gross Weight
Fine Gold Weight = Gross Weight × Purity
Fine Gold $/g = Effective Cost ÷ Fine Gold Weight

Gross Cost vs Fine-Gold Cost

A 100-gram product that is 90% pure contains less fine gold than a 100-gram product that is 99.99% pure. Comparing only gross $/gram can therefore produce a misleading result. Fine-gold cost normalizes the comparison.

Why Include Shipping and Taxes?

The displayed product price is not always the actual acquisition cost. Adding unavoidable expenses reveals what each gram really costs to own.

When comparing dealers, use the same cost basis for every product or the ranking can be distorted.
