Calculate the value of your scrap gold based on weight, purity (karat), and current market prices. Get accurate estimates for jewelry, coins, and gold items.
Enter your gold information to see value
Use a precise scale to measure your gold's weight in grams, ounces, or pennyweights.
Check for karat markings (10K, 14K, 18K, etc.) or test the gold's purity percentage.
Enter the current gold spot price per troy ounce from reliable market sources.
Receive accurate calculations including melt value and estimated dealer payout.
Gold purity is measured in karats (K), with 24K being pure gold (99.9%). Lower karat gold contains other metals for durability. The purity percentage determines how much actual gold content your item contains.
The spot price is the current market price for pure gold. Scrap gold dealers typically pay 70-90% of the melt value, depending on the item's condition, purity, and current market conditions.
The current market price for immediate delivery of pure gold, typically quoted per troy ounce.
The intrinsic value of gold based on its weight and purity, calculated using current spot prices.
The standard unit for measuring precious metals, equal to 31.1035 grams or 1.097 regular ounces.
A unit of measurement equal to 1/20 of a troy ounce, commonly used in jewelry trading.
This calculator provides estimates for informational purposes only. Actual gold prices fluctuate constantly, and dealer payouts vary. Always verify current market prices and get multiple quotes from reputable gold dealers before selling.
Every result you see is calculated the same way a refinery does it: convert your weight to grams, isolate the pure gold percentage, and multiply by the current price per gram.
1) Normalize weight: grams are the base. Ounces are multiplied by
31.1035, pennyweights by 1.55517, and pounds by 453.592 to reach
grams.
2) Pure gold mass:
pure grams = total grams × (purity % ÷ 100).
3) Melt value:
melt value = pure grams ×
price per gram.
4) Dealer payout: if you enter a payout %, we apply it to
the melt value to estimate your check.
Say you have 42 grams of 14K scrap. Purity is 58.3%, so pure gold = 42 × 0.583 = 24.486 grams (0.7875 troy oz). If spot price is $2,100 per troy oz, that equals $67.54 per gram. Melt value = 24.486 × 67.54 = $1,653.55. If a dealer pays 85%, expected payout is about $1,405.52. Enter those numbers above and you should see the same totals, matching Omni Calculator outputs.
Real scenarios that mirror what gold buyers see every day, with quick math so you know your leverage.
10K = 41.7% pure. Pure grams = 12 × 0.417 = 5.004 g. At $67.54/g spot, melt = $338. A fair pawn payout at 80% is ~$270.
18K = 75% pure. Pure grams = 22.5 g. Melt at $67.54/g is ~$1,520. Dealers that resell may offer 85–92% (~$1,290–$1,398).
When purity varies, use the % tab and enter an average (often 60–70%). At 65%, pure grams = 10.4 g; melt ≈ $702; payout at 75% ≈ $526.
A 24K Maple Leaf carries collector premiums. Melt equals spot, but selling to a bullion dealer may get 98–102% of spot. Use the calculator for melt; check dealer premiums separately.
In California, bullion under $1,500 can be taxable; larger transactions may be exempt. Texas generally exempts bullion. Ask dealers about documentation requirements and keep receipts for capital gains tracking.
Weigh item in front of you, ask which karat they recorded, note their payout %, and compare against this calculator. Bring a printed quote; many dealers will match or beat a competitor by 1–2%.
Bridge the gap between the spot price you see online and the offer a local dealer makes.
Offers below these bands are usually negotiable—show your math.
Public spot feeds typically refresh every 60 seconds. Refresh this page or update the price box to align with the latest market move. Volatile days can swing $20–$40 per ounce within an hour, which is $0.64–$1.29 per gram.
Tip: lock a dealer quote in writing when the market is calm; rapid moves often lead to wider spreads.
