Gold Melt Calculator - Scrap Value Estimate

The gold melt calculator estimates the metal value of a gold item from its weight, purity, market price, and expected buyer payout. Use it before selling broken jewelry, comparing pawn or refinery offers, valuing inherited pieces, or separating bullion value from sentimental value. It gives a planning number for the gold content only, not a binding appraisal.

• • Scrap jewelry review: Estimate the fine-gold value of rings, chains, earrings, and broken pieces after entering the stamped karat.
• • Offer comparison: Change the buyer payout percent to see how a 75%, 85%, or 95% offer compares with gross melt value.
• • Mixed-lot sorting: Run separate estimates for 10K, 14K, 18K, and custom purity lots before combining the totals.
• • Bullion sanity check: Compare a bar or coin estimate with the quoted price per troy ounce after confirming the unit and purity.

Melt value is the value of the fine gold inside the item. It does not include retail markup, brand value, gemstones, craftsmanship, collectible premium, tax, shipping, or assay fees. A buyer may also pay less than gross melt value because refining, hedging, fraud risk, and operating margin cost money.

Use the result as a negotiation reference. If a buyer offer is far below your estimated payout range, ask whether stones, non-gold parts, minimum lot charges, or testing uncertainty are reducing the offer. If an item may be collectible or designer-made, get a separate appraisal before treating it as scrap.

If you are deciding whether to sell gold or keep capital invested, the investment calculator can model an alternative growth path.

The calculator follows the same sequence a precious-metals buyer uses: weigh the lot, adjust for purity, convert fine gold into troy ounces, then apply the chosen price and payout.

• Weight in grams: The entered weight after converting grams, troy ounces, pennyweights, or standard ounces into grams.
• Purity fraction: The karat divided by 24, or the custom purity percent divided by 100.
• 31.1034768: The number of grams in one troy ounce used for precious-metals pricing.
• Buyer payout: The percent of gross melt value that remains after the buyer spread.

Karat is a purity ratio, not a weight unit. A 14K item is modeled as 14 parts gold out of 24 total parts, so only part of the item weight becomes fine gold. The remaining alloy can include copper, silver, nickel, zinc, or other metals depending on color and manufacturing needs.

Gold spot prices are quoted in troy ounces, while kitchen and postal scales often show grams or standard ounces. This is why the unit selection matters. A standard ounce is lighter than a troy ounce, so entering the wrong ounce type can move the value enough to affect a sale decision.

According to NIST, one troy ounce equals 31.1034768 grams for precious-metals conversions.

According to FTC Consumer Advice, 18K gold is 18 parts gold mixed with six parts another metal, which supports modeling karat purity as karat divided by 24.

If your gold quote and buyer payment use different currencies, convert the price first with the currency converter calculator.

A useful melt estimate depends on four ideas: fine weight, karat purity, troy pricing, and buyer spread. Each one changes the number in a different way.

Do not mix jewelry weight and fine-gold weight when comparing offers. A buyer who says a 14K bracelet weighs 20 grams is not saying it contains 20 grams of gold. The fine-gold estimate is closer to 11.67 grams before assay tolerance, solder, stones, and non-gold parts are considered.

The custom purity field is useful for hallmarks such as 916, 750, or 585, and for assay reports that state a percent. Enter 91.6 or 91.7 for many 22K-style references, 75 for 18K, or the exact percent shown on a reliable report.

For exchange-traded exposure rather than physical scrap, the futures contract calculator helps compare notional value and margin assumptions.

Use one consistent price, unit, and purity assumption for each item or lot. For mixed purity, run separate calculations and add the payout values.

1. 1 Weigh the item: Remove stones or non-gold parts if possible, then enter the weight from your scale.
2. 2 Choose the unit: Select grams, troy ounces, pennyweights, or standard ounces to match the scale or dealer worksheet.
3. 3 Select purity: Use the karat stamp when you trust it, or choose custom purity for a fineness mark or assay report.
4. 4 Enter price: Type the gold price per troy ounce in the currency you want the result to use.
5. 5 Set payout percent: Use 100% for gross melt value only, or a lower percent to model a buyer offer.
6. 6 Compare the outputs: Review gross melt value, estimated payout, spread, fine weight, and payout per pure gram.

Suppose a 14K chain weighs 18 grams and your buyer says they pay 88% of melt. Enter 18 grams, 14K, the current gold price per troy ounce, and 88%. The payout result is the offer benchmark; the gross melt value shows the theoretical metal value before the buyer spread.

After a sale, the holding period return calculator can compare your original cost with the cash value received.

A melt estimate is most useful when it turns a vague offer into numbers you can inspect. The outputs help with selling, recordkeeping, and risk checks.

• • Separates metal value from resale story: You can see what the gold content is worth before considering brand, condition, design, or sentimental value.
• • Compares buyer offers: Changing the payout percent shows whether two offers differ because of price assumptions or buyer spread.
• • Checks unit confusion: The unit selector reduces mistakes between grams, pennyweights, troy ounces, and standard ounces.
• • Supports estate notes: You can document a repeatable estimate for inherited jewelry before deciding what needs a formal appraisal.
• • Frames portfolio liquidity: Gold held as jewelry may be less liquid than cash or brokerage assets because sale price depends on testing and buyer terms.

Use the payout per pure gram when comparing buyers who quote different formats. One buyer may quote a total offer, another may quote per gram of 14K, and a refinery may quote a percent of melt. The gold melt calculator converts those pieces into a comparable result so the spread is easier to see.

Keep screenshots or notes with the gold price, date, and buyer payout percent used. Gold prices move, so a good estimate from one day can be stale on another day. The model is strongest when the price input matches the time and currency of the offer.

If you track gold as a sellable asset, the liquid net worth calculator can show how much of your net worth is readily spendable.

The estimate changes when weight, purity, price, or buyer terms change. Real transactions can also include details the calculator cannot see.

• • The calculator assumes the selected purity applies to the entire entered weight. It cannot detect plating, filled jewelry, solder differences, or mixed-metal parts.
• • The result is not a live bid, appraisal, tax value, or firm sale quote. Confirm testing method, fees, payment timing, and price source with the buyer.

If you are valuing coins or bars, confirm whether the quoted price is for fine gold content or for a specific product premium. Some bullion products trade above melt because they are recognizable, liquid, or scarce. Other items may sell below melt when assay cost is high or lot size is small.

For taxes, estate records, insurance, or a high-value sale, document the source of the price quote and consider a qualified appraisal. A melt estimate is a practical screening tool, but it does not replace professional testing or legal valuation guidance.

According to LBMA, gold appears in its precious-metal price data, so users should enter a gold price that matches their chosen market quote and currency.

When the sale price is known, the percentage return calculator can measure the gain or loss against your purchase cost.
