How to use the holdings calculator
Add each parcel of gold or silver you own as a separate row. For each holding pick the metal, the unit you measure it in (troy ounces is standard for bullion, grams for jewellery, kilos for larger bars), the purity (99.9% for most modern bullion, 91.67% for 22k jewellery, 58.33% for 14k), and the quantity.
If you remember what you paid, enter the total purchase price for that lot. The calculator will track unrealised gain or loss against the current spot price you set at the top. Leave it blank if you do not want to track cost basis — the value calculation still works.
The portfolio summary on the right rolls everything up: total dollar value, gold vs silver split, total pure ounces of each metal, and overall profit or loss. Use the Export JSON button to save a backup — the data lives only in your browser's local storage.
What spot price should you use?
The default values are illustrative. To get accurate current numbers, look at the live XAU/USD and XAG/USD charts on the main charts page and copy the latest figure into the spot input. Bullion dealers add a premium on top of spot when you buy and discount slightly below spot when they buy back, but spot is the fair "melt" reference value of the underlying metal.
