Estimate the net cost of remaking old gold jewellery by separating old-gold credit from new metal, labour and additional remake charges.
The old jewellery is credited using its fine-gold content and the credit rate you enter. The new item's gold requirement and service costs are then added to determine the net additional amount.
A customer may see only one final figure, but old-gold credit, new metal, labour and other charges answer different questions. Separating them makes the economics easier to audit.
A workshop may value old gold differently from the selling price of new jewellery. The calculator therefore lets you enter the actual credit rate used in the scenario rather than assuming both are identical.
No. Purity must be considered before converting the old item into fine-gold content.
Yes. That means the entered old-gold credit exceeds the modeled new-gold and service costs.
No. Stone value and stone-removal adjustments should be handled separately.
