This Scrap Silver Calculator totals the melt value of a mixed silver lot. Add each piece with its fineness, weight, and unit, then enter a spot price per troy ounce and a buyer payout rate. The tool returns total weight, pure silver content, melt value, and estimated payouts from refiners, dealers, pawn shops, and mail-in services. Get a clear silver valuation without manual conversions.
A drawer of orphaned silver, bent flatware, single earrings, pre-1965 coins rarely shares one purity mark. That is where this Scrap Silver Calculator earns its keep. It values a mixed-fineness lot rather than a single piece, so you can list each item separately and still see one consolidated total. Enter the current spot price per troy ounce, add items with their fineness codes and weights, and choose a payout percentage or buyer type. The calculator reports total weight, pure silver, melt value, and a side-by-side payout comparison. It suits estate sorting, coin jar cleanouts, jewellery repairs, and anyone comparing offers before selling. Treat it as a transparent baseline for negotiation.
Select a display currency from the dropdown. This alters the symbol shown, not the conversion.
Type the silver spot price per troy ounce. The per-gram price appears automatically.
Add each scrap item on its own row.
Choose a fineness code for every item, or leave Custom, which maps to 0% purity in this version.
Enter the weight and pick grams, pennyweight, troy ounces, or standard ounces.
Set the payout percentage, or choose a buyer type to load a preset rate.
Press Calculate to refresh totals, or click a buyer card to compare payout levels.
Inspect the totals strip, item breakdown table, and analysis panel.
The Scrap Silver Calculator converts every item to grams, multiplies by its fineness purity, and values the pure silver at the spot price per gram.
Formula: Price per gram = spot price per troy ounce ÷ 31.1034768
Formula: Grams = weight in g, or weight in dwt × 1.555, or weight in ozt × 31.1034768, or weight in oz × 28.349523125
Formula: Purity % = fineness ÷ 10 (example: 925 fineness = 92.5% purity)
Formula: Pure silver grams = grams × (purity % ÷ 100)
Formula: Item melt value = pure silver grams × price per gram
Formula: Lot melt value = sum of all item melt values
Formula: Payout amount = lot melt value × (payout % ÷ 100)
Formula: Buyer comparison payout = lot melt value × preset buyer % ÷ 100
The payout percentage is clamped to 0–100. A negative spot price is treated as zero. The fineness list includes 999, 958, 925, 900, 835, 800, 720, 500, 400, and Custom. Custom maps to 0% purity in this version; there is no separate purity field for silver items. The currency selector changes the displayed symbol only and does not perform foreign-exchange conversion. If total melt value is zero, the badge shows Add Items. Payout badges are based on thresholds: 90% or more is refiner-level, 70–89% is fair, 50–69% is below average, and under 50% is poor. Buyer presets are refiner 93%, dealer 75%, pawn shop 50%, and mail-in 45%.
Suppose your silver scrap lot holds 250 g of sterling flatware (925 fineness), 100 g of coin silver (900 fineness), and 50 g of fine silver (999 fineness). The silver spot price is $30 per troy ounce, and you want to test a 75% dealer payout.
Step 1: Convert spot price to price per gram.
$30 ÷ 31.1034768 = about $0.9645 per gram.
Step 2: Calculate pure silver for each item.
Sterling flatware: 250 g × 92.5% = 231.25 g pure silver.
Coin silver: 100 g × 90.0% = 90.00 g pure silver.
Fine silver: 50 g × 99.9% = 49.95 g pure silver.
Step 3: Add the pure silver.
231.25 + 90.00 + 49.95 = 371.20 g pure silver.
Step 4: Calculate melt value.
Sterling flatware: 231.25 g × $0.9645 = $223.04.
Coin silver: 90.00 g × $0.9645 = $86.81.
Fine silver: 49.95 g × $0.9645 = $48.18.
Total melt value = $358.03.
Step 5: Apply the payout rate.
$358.03 × 75% = $268.52.
The lot weighs 400 g, contains 371.20 g of pure silver, and has a melt value near $358.03. At a 75% dealer rate, the estimated payout is about $268.52. A refiner preset of 93% would show roughly $332.97, which is why comparing buyer types before selling matters.
It values a mixed lot of silver scrap items. You list each piece, choose its fineness and weight unit, enter a spot price, and set a payout rate. The tool returns total melt value and buyer payout estimates.
Every row has its own fineness selector. The calculator applies the matching purity percentage to that row only, then sums the pure silver and melt value across the lot. This keeps 999, 925, 900, 800, and other grades separate.
Enter the current silver spot price per troy ounce in your chosen currency. The calculator divides it by 31.1034768 to get the price per gram. It does not fetch live prices, so use a recent quote from a refiner or market source.
Buyers rarely pay full melt value. The payout percentage models the discount a refiner, coin dealer, pawn shop, or mail-in service applies. Changing this field shows how the same lot would perform under different buyer rates.
Yes. Each item row supports grams, pennyweights (dwt), troy ounces (ozt), and standard ounces (oz). The calculator converts dwt, ozt, and oz to grams before applying fineness and price, so you can enter weights in the unit stamped on the item or scale.
No. The currency dropdown changes the symbol displayed in the results. It does not perform foreign-exchange conversion. Enter the spot price and payout values in the same currency you select.
Melt value is the market worth of the pure silver content in an item or lot. It is calculated from weight, fineness, and the price per gram. It does not include gemstones, craftsmanship, brand premiums, or collector value.
Refiners generally pay the highest percentage of melt value. The calculator’s preset comparison shows refiners at about 93%, dealers around 75%, pawn shops near 50%, and mail-in services around 45%. Actual offers vary by quantity, location, and fees.
You can add as many rows as you need using the Add another item button. The totals strip and breakdown table update with each row. For large lots, the analysis may suggest sorting by fineness before requesting quotes.
Payout is lower because buyers charge for refining, assay, shipping, and profit. The difference between melt value and payout is not a calculation error; it is the buyer’s margin and cost structure. Comparing multiple buyer types can reduce that gap.
Yes. The tool is free to use, and the calculations run client-side in your browser. Your item descriptions, weights, and payout entries are not transmitted to a server by the calculator itself.
In this version, the Custom fineness option maps to 0% purity. It does not open a field for entering a different purity percentage. To value a non-standard fineness, choose the closest preset or use a dedicated silver purity converter first.
