Silver Calculator
Subtract independently measured non-metal weight, enter silver purity as percent or millesimal fineness, and apply a user-entered spot price, currency label, and payout rate.
How to use the Silver Calculator
Enter gross and excluded non-metal weight, unit, purity percent or fineness, spot price per troy ounce, currency, and payout percentage.
Review hallmarks, assay, weighted items, stones, plating, troy conversion, price timestamp, collectible premium, and dealer spread.
Read gross grams, pure grams, pure troy ounces, melt value, and estimated payout.
Formula
Pure silver weight = gross metal weight × purity percentage ÷ 100. Melt value = pure troy ounces × entered spot price; estimated payout = melt value × payout percentage.
Example
100 g of silver entered at 92.5% purity contains 92.5 g of pure silver before assay variance.
Assumptions and limitations
- The entered fineness applies uniformly and the entered price is a scenario; no authenticity, live-price, or collectible-value claim is made.
- Silver Calculator treats the entered values as estimates and does not infer missing project, account, or personal details.
- Calculations retain working precision except where the cited method requires an intermediate rounding step; displayed values are then formatted separately. Source rules and dated rates must be rechecked when they change.
