Refining Fee Formula

Per-Gram Charge = Feed Weight × Per-Gram Rate
Value Fee = Gold Value × Rate %
Total Fee = Per-Gram Charge + Value Fee + Fixed + Assay

Normalize Fees Against Fine Gold

A $10,000 fee means different economics for a 100-gram fine-gold lot versus a 5-kilogram lot. Dividing the total fee by fine-gold weight makes the comparison more meaningful across batches.

Fee schedules may use different bases: feed weight, fine metal value, fixed charges or assay services. Always check what each provider's quoted fee actually applies to.
