Scrap Silver Calculator
Combine matching silver scrap-lot weights and purity percentages in one common unit, then show theoretical melt value and payout from user-entered rates.
How to use the Scrap Silver Calculator
Enter matching scrap weights, non-metal exclusions, and purity percentages, plus unit, spot price, currency, payout percentage, and fixed fee.
Review assay, plating, filled or weighted pieces, solder, scale unit, price timestamp, minimum lots, refining loss, and buyer terms.
Read pure grams, pure troy ounces, theoretical melt value, and estimated payout.
Formula
For each lot, fine silver = (gross weight − entered non-metal weight) × purity percentage ÷ 100. Payout = max(0, total melt value × payout percentage − fixed buyer fee).
Example
250 g of silver entered at 80% purity contains 200 g fine silver before assay and refining adjustments.
Assumptions and limitations
- Every lot is modeled at its entered homogeneous fineness; actual payable metal depends on assay and the buyer’s documented settlement.
- Scrap 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.
