Scrap Silver Calculator - Weight and Purity Value

The scrap silver calculator estimates what a lot of sterling, coin silver, or bullion is worth at melt, then optionally applies a selling price and a tax rate so you can see net proceeds. Fine silver content is weight × (purity ÷ 100). Sterling is typically 92.5%, coin silver is often 90%, and many modern bars are 99.9%. Multiply fine ounces by the spot price per troy ounce to get melt value. If you leave selling price blank, that melt value is the starting point; if you enter an offer, the offer replaces melt before tax is applied. Weight should be troy ounces because silver is quoted per troy ounce. A kitchen-scale gram reading must be divided by 31.1035. Flatware, candlesticks, and jewelry often include stainless blades, glass, or stones that are not silver; weigh only the silver portion or the melt value will be too high. Magnet tests and hallmarks help, but plated ware can fool a casual inspection. An XRF gun or a known maker’s mark is more reliable than wishful thinking on a “silver plate” stamp. Dealers pay a percentage of melt, not the full spot, because they must refine, hedge, and hold inventory. A 5–15% haircut is common on mixed sterling; large 999 bars closer to spot. The optional selling-price field is there so you can drop in a shop’s offer and then apply sales tax or a local tax on the transaction if it applies in your jurisdiction. Many private sales of bullion are treated differently from jewelry retail, so do not assume a tax applies without checking local rules. Use the scrap silver calculator to compare two offers, to decide whether breaking a set is worth it, and to avoid confusing plated weight with sterling weight. Spot silver is volatile; an evening quote can be stale by the next London fix. The result is an educational estimate of melt or net proceeds, not an appraisal or a binding bid, and it is not tax advice. Confirm purity, weight, and the live bid before you sell.
