Gold Per Gram Value Calculator (Karat-Based)

If you have ever wondered how much is 14k gold a gram, the answer depends on three things: the current spot price of pure gold per troy ounce, the karat purity of your item (14k means 58.3% pure gold), and the weight in grams. As of late 2026, gold spot prices have hovered around $2,400 per troy ounce, which translates to roughly $77 per gram of pure 24k gold and about $45 per gram of 14k gold before refining or dealer fees. A 10-gram 14k chain at that rate would carry a melt value near $450.

This calculator converts any spot price into a per-gram price for the karat you select, then multiplies by your weight to estimate melt value. You can override the karat (10k, 14k, 18k, 22k, 24k), enter weight in grams or troy ounces, and apply a buyer payout percentage to see what a pawn shop or refiner might actually offer. The defaults reflect 2026 market conditions, but you should plug in today’s spot price for the most accurate result — gold can swing 2–5% in a single week.

How it works: Enter the spot price of gold, your item's karat, and its weight. The tool computes the per-gram price for that karat and your estimated melt value, with an optional buyer payout to model real-world offers.

Understanding 14k Gold Pricing Per Gram in 2026

Gold pricing is straightforward once you know the three levers: spot price, karat purity, and weight. This guide walks through realistic 2026 numbers, why 14k is the most common karat in U.S. jewelry, and how to avoid being underpaid when selling.

What does 14k actually mean?

Karat (k) measures gold purity in 24ths. A 14k item contains 14 parts pure gold and 10 parts other metals (typically copper, silver, zinc, or nickel), giving a purity of 14/24 ≈ 58.3%. So if pure 24k gold trades at $77 per gram, 14k is worth roughly $45 per gram in raw metal content. Rule of thumb: multiply the 24k per-gram price by 0.583 to get the 14k per-gram price. The remaining 41.7% of the alloy has trivial scrap value and is generally ignored by gold buyers.

How to convert spot price to per-gram value

Gold spot is quoted in U.S. dollars per troy ounce, and one troy ounce equals 31.1035 grams (not 28.35 — that's a regular ounce). To get the per-gram pure-gold price, divide the spot price by 31.1035. At a $2,400 spot price, that's $77.16 per gram of 24k. Multiply by your karat purity fraction to get the per-gram price for your item. A common shortcut: 14k per-gram ≈ spot ÷ 53.3. Always confirm the spot price the same day you transact, because gold can move 1–3% intraday.

Weighing your gold accurately

Use a jewelry scale that reads to 0.01 g — kitchen scales rounded to whole grams will cost you money. Remove gemstones, clasps, and non-gold pieces if you can, since buyers will deduct their estimated weight anyway. Hollow chains, plated items, and gold-filled pieces are NOT solid gold and won't price by these formulas. As a guideline, a typical 14k wedding band weighs 4–7 g, a women's chain 5–15 g, and a men's chain 15–60 g. Pawn shops will independently weigh and test purity before quoting.

Why buyers don't pay full melt

Even at a refiner, you'll rarely see 100% of melt value because the buyer must cover assay testing, refining losses (typically 1–3%), shipping insurance, and their profit margin. Pawn shops add a much larger spread — often 35–50% — because they bear inventory risk and resale costs. A useful rule of thumb: refiners pay 85–95%, jewelers 65–80%, and pawn shops 40–65%. If a buyer offers below 50% without a clear reason, walk away and get a second quote.

When jewelry is worth more than melt

Designer-signed pieces (Cartier, Tiffany, Bulgari, Van Cleef), antique items with hallmarks, and coins with numismatic value can fetch 2–10x their melt price on the secondary market. Before scrapping a piece, search recent sold listings on auction platforms for the same model. Solid 18k or 22k items with intricate craftsmanship also retain craft premium. As a guideline: if a piece is over 50 years old, signed by a known maker, or includes natural gemstones, get an appraisal before melting.

Taxes and reporting when selling gold

In the U.S., profits from selling personal gold are taxed as collectibles at up to 28% federally, plus state tax. Dealers must file IRS Form 1099-B for certain bullion sales (e.g. 25+ Krugerrands or 1 kg of gold bars), but scrap jewelry sales typically aren't reported. Keep records of purchase price and date — without basis records, the IRS may treat the full proceeds as gain. As a guideline, sales under $600 from a single buyer rarely trigger paperwork, but you're still legally obligated to report the income.

How This Calculator Works: Methodology & Parameter Explanations

Core formula: pricePerGramPure = spot_price / 31.1035; pricePerGramKarat = pricePerGramPure × (karat / 24); meltValue = grams × pricePerGramKarat; payoutValue = meltValue × (payout_percent / 100). Weight conversion: if input is troy ounces, grams = ozt × 31.1035.

Parameter explanations

Assumptions

The headline phrasing 'how much is 14k gold a gram' is an example default — the calculator works for any karat (10k–24k) and any weight; the example numbers are not hard-coded.

Spot price is treated as the all-in market price; bid-ask spread (typically 0.1–0.5%) is ignored.

The 41.7% non-gold alloy in 14k is assumed to have negligible scrap value (true for copper/zinc; slightly understated if the alloy contains silver).

Stones, clasps, and non-gold attachments are assumed to have been removed or excluded from the entered weight.

Taxes, shipping, and insurance fees are not deducted from the displayed payout — subtract them separately for a net-cash estimate.
