Scrap Gold Calculator

How to use this scrap gold value calculator

Selling scrap gold comes down to three numbers: what your item weighs, how pure it is, and the current spot price. This calculator handles the math. Step one, weigh your item and enter the weight in the unit your scale shows. Step two, select the karat marked on the piece. Step three, read the results: the melt value at the current spot price, and the range a real buyer is likely to offer.

You can switch between grams, troy ounces, regular ounces, pennyweight, and other units at any time, and the karat list covers everything from 10K costume-grade alloys to 24K bullion. If your scale reads metric, the gold calculator in grams opens with grams preselected; if it reads ounces, the gold calculator in ounces handles the troy-versus-kitchen-scale distinction that trips up most first-time gold sellers.

Step-by-step example: pricing a 14K gold chain

Here is the full calculation once, so you can see what happens behind the results card. Suppose you have a 20-gram 14K gold chain, and take a spot price of $4,000 per troy ounce for illustration. First convert the spot price to grams: $4,000 ÷ 31.1035 = $128.60 per gram of pure gold. Next apply the purity: 14K is 58.3% gold, so $128.60 × 0.583 = $74.97 per gram. Finally multiply by the weight: $74.97 × 20 g ≈ $1,499 — the chain's melt value.

Now layer on the payout ranges. At 55–70% of melt, a pawn shop would offer roughly $825–$1,050 for that chain. A local jeweler at 70–85% lands around $1,050–$1,275, an online gold buyer at 80–95% pays about $1,200–$1,424, and a refiner at 95–98% returns $1,424–$1,469. The 14k gold calculator runs this exact chain of math at the live spot price, with the karat preset for you.

Melt value vs. what buyers actually pay

Melt value is the theoretical worth of the pure gold in your item at the current spot price. No buyer pays 100% of it, because refining, assaying, and resale all cost money. In practice, offers cluster by buyer type: pawn shops typically pay 55–70% of melt, local jewelry stores 70–85%, online gold buyers 80–95%, and refiners 95–98% (refiners usually require larger lots).

Knowing the melt value of your gold before you walk in is the single best defense against a lowball offer. If a quote lands below 55% of the number this calculator shows, walk away and get a second opinion.

Why two shops quote wildly different gold prices

Bring the same bag of scrap gold to four buyers and you can get four offers spread across a 40-point range. That is not necessarily dishonesty — each buyer type carries different costs. A pawn shop ties up cash in items that may sit for months, so it protects itself by paying 55–70% of melt. A local jeweler resells or remelts faster and can stretch to 70–85%. Online gold buyers run high-volume, low-overhead operations and pay 80–95%, and refiners — who melt the gold themselves — pay 95–98% but usually only on larger lots.

The spread means the order you visit buyers in matters less than knowing your melt value before the first quote. It also means quotes are only comparable in the same unit: pawn counters traditionally price gold in pennyweight rather than grams, and the dwt gold calculator translates those quotes so you can line them up against gram-based offers.

How to weigh your gold at home

An ordinary kitchen scale works for a first estimate, though most only resolve to a full gram. A pocket jewelry scale with 0.1 g accuracy costs around $10 and pays for itself on the first sale. Weigh each karat group separately, and remove or estimate the weight of any gemstones, since buyers only pay for the gold.

Weigh on a hard, level surface and calibrate with a known weight if your scale supports it. For pieces with stones, weigh the item first, then estimate the stones: a one-carat diamond is 0.2 grams, and most accent stones together weigh well under a gram. A slightly generous stone deduction costs you far less than a buyer catching an inflated gold weight and re-anchoring the whole negotiation.

Reading the karat stamp on gold jewelry

Look inside ring bands, on clasp tags, or on the back of pendants for a tiny stamp. American pieces usually read 10K, 14K, or 18K. European pieces use millesimal fineness instead: 585 means 14K and 750 means 18K. A 417 stamp is the millesimal equivalent of 10K, and bullion is stamped 999 or 9999. If there is no stamp, or the stamp looks worn or suspicious, an acid test kit can confirm the karat before you sell.

Millesimal marks map straight onto karat presets: a 750 stamp means 18K — three-quarters pure gold — and the 18k gold calculator has that purity preset. Watch for letters after the number, though. Marks like GP, GF, HGE, or RGP mean plated or filled pieces that carry only a thin layer of gold over base metal; they are worth a small fraction of solid gold, and many scrap buyers refuse them outright.

Common mistakes that shrink your gold payout

Four errors cost gold sellers the most. First, accepting a quote made at half a karat below the stamp — some buyers price 14K as if it were 13.5K and call it a hedge, so ask what purity they used. Second, the ounce mix-up: a kitchen scale reads regular ounces, about 10% lighter than the troy ounces gold prices are quoted in, and a careless conversion overstates what you have. Third, forgetting stone weight — buyers pay for metal only, and gemstones priced as gold will be corrected at the counter, never in your favor.

Fourth, selling into the wrong channel: bullion coins taken to a pawn shop get jewelry-scrap rates, and dental crowns sold locally get quoted at the lowest plausible karat. Match the item to the buyer, get at least two quotes, and anchor every negotiation to the melt value this page calculates before anyone else puts your gold on a scale.
