Scrap Gold Value Calculator

Estimate your scrap gold's metal value before selling

Scrap gold buyers generally pay for recoverable metal rather than an item's original retail markup, workmanship, or personal history. A broken chain, unmatched earring, damaged ring, dental alloy, or tangled jewelry lot may still contain valuable gold. Its estimated melt value depends on three facts: the material's weight, its karat purity, and the gold market price. This calculator combines those inputs to give you a metal-value benchmark before you speak with a jeweler, pawn shop, cash-for-gold buyer, or refiner.

The displayed figure is not a guaranteed purchase offer. Melt value represents the theoretical value of the pure-gold portion at the spot price you provide. A buyer may pay less because sorting, stone removal, assaying, refining losses, hedging, and operating margin all affect a quote. For that reason, this page also shows examples at 90 percent and 80 percent of melt value. They are comparison points, not promised dealer rates.

This scrap-gold estimate is most useful when you have a scale reading, a karat hallmark or test result, and a current spot price from a market source you trust. It can also help you sort a mixed jewelry lot into 10k, 14k, 18k, or 24k groups before requesting bids. The purpose is to translate a jewelry item's weight and karat into an understandable gold-content value.

How to enter scrap gold details accurately

To obtain a useful scrap-gold estimate, first decide whether you need a metal benchmark or a way to evaluate a buyer's quote. The form then uses the same inputs a buyer considers when valuing gold for refining.

1. Weigh the item or sorted lot and enter that amount in the Weight field.
2. Select the correct Weight unit. The calculator accepts grams and troy ounces.
3. Enter Purity in karats, using a hallmark or the result of an appropriate metal test.
4. Enter the current Gold Price per Ounce. Gold quotations normally refer to troy ounces, not household ounces.
5. Press Estimate to see melt value, purity fraction, and the two payout comparisons.

For a mixed scrap-gold lot, calculate each karat group separately rather than entering an average purity. Separating 10k, 14k, and 18k material produces a clearer estimate and shows which portion of the lot contributes most of the value.

The form begins at zero so no sample price is mistaken for a live gold quotation. Enter fresh figures whenever you use it, then verify the unit, karat, and spot price before relying on the result.

Scrap gold inputs explained

Gold-bearing weight

For scrap gold, weight should reflect the material you expect a buyer to value as gold-bearing. A ring with a gemstone, a watchband with steel components, or earrings with non-gold backs can weigh more than their recoverable gold content. The calculator cannot identify stones, springs, solder, clasp inserts, or other attached material; it treats the entered weight as eligible for the chosen purity. Remove obvious non-gold parts when possible, or allow for the estimate to be high when they remain attached.

Grams versus troy ounces

Scrap jewelry is often weighed in grams, while gold market prices are typically quoted per troy ounce. The troy-ounce option is for weights already measured in the precious-metals system; it is not the ordinary avoirdupois ounce used for food and shipping. One troy ounce equals 31.1035 grams, and the calculator uses that conversion when matching your weight to the ounce-based gold price.

Karat purity of scrap jewelry

Karat identifies the fraction of an item that is gold. Since pure gold is 24k, this calculator divides the entered karat by 24 to find the purity fraction. These common marks provide useful reference points:

• 10k = 10 / 24 = 41.67 percent gold
• 14k = 14 / 24 = 58.33 percent gold
• 18k = 18 / 24 = 75 percent gold
• 22k = 22 / 24 = 91.67 percent gold
• 24k = 24 / 24 = 100 percent gold

A hallmark is a useful starting point, but it is not an assay. Repairs, plating, hollow construction, wear, or inaccurate markings can affect what a buyer accepts as the payable purity. For a valuable lot, professional testing or an XRF reading can provide a tighter basis for valuation.

Gold spot price per troy ounce

The gold-price field is the market quote per troy ounce used to value your scrap gold. The calculator divides that figure by 31.1035 to obtain a price per gram of pure gold. Its 90-percent and 80-percent rows illustrate how a dealer discount changes the theoretical melt amount; they do not predict an individual buyer's offer.

Scrap gold melt-value formula and conversion

This scrap-gold calculation first converts the ounce quote to a price per gram, converts karat to a purity fraction, and then multiplies both by the entered weight. The formula used is:

In this formula, V is estimated melt value, W_g is weight in grams, K is the karat value, and P_oz is the gold price per troy ounce. The 31.1035 constant converts one troy ounce to grams. When you select troy ounces as the weight unit, the calculator converts that input to grams before applying the formula.

The two dealer comparisons are direct percentages of calculated melt value: 90 percent and 80 percent. Actual payouts vary with the buyer, assay confidence, lot size, sorting, and refining requirements, so use these figures as context for comparing quotes rather than a fixed industry schedule.

When a lot contains several karat groups, calculate each group independently and add the resulting melt values. This avoids assigning one blended purity to items whose actual gold content differs substantially.

Worked scrap gold example: 14k necklace

Consider a broken 14k necklace weighing 18.5 grams when the gold price is 2,400 dollars per troy ounce. The ounce quote converts to about 77.16 dollars per gram of pure gold. The 14k purity fraction is 14 divided by 24, or 0.5833. Applying the calculator's formula gives a theoretical melt value of about 832.70 dollars.

That 832.70-dollar figure is the metal benchmark, not necessarily the amount a buyer will offer. A 90-percent payout would be about 749.43 dollars, while an 80-percent payout would be about 666.16 dollars. If an offer falls well below such a comparison, ask whether stones, non-gold components, solder, testing uncertainty, or the buyer's payout policy explains the difference.

How scrap gold weight changes melt value

This table holds purity at 14k and the gold price at 2,400 dollars per troy ounce while changing only the gold-bearing weight. It demonstrates the direct relationship between eligible weight and estimated melt value.

For scrap gold of one stated purity, the formula is proportional to weight. Doubling the eligible gold-bearing weight doubles the estimated melt value when karat and spot price are unchanged.

Reading a scrap gold result realistically

When reviewing a scrap-gold estimate, check three things. First, confirm the weight unit: a gram reading should remain in grams, and a troy-ounce entry must actually use the precious-metals ounce. Second, confirm purity: 14k is only 58.33 percent gold, so it should value far below the same weight of 24k gold. Third, compare theoretical melt with the 90-percent and 80-percent reference rows, remembering that a real buyer may use different assumptions.

The result works best as a sorting and negotiation reference. Calculate separate karat groups, keep notes about their weights, and ask a buyer to explain any large difference from your estimate. A quote near the higher comparison may be relatively strong for clean, readily assayed material, while a lower figure may reflect non-gold content or a buyer's policy. The calculator is intended to clarify the metal math, not to promise an exact check amount.

Scrap gold assumptions and valuation limits

This scrap-gold calculator cannot inspect the item in front of you. It assumes the entered weight is relevant gold-bearing material, the entered karat is accurate, and the market quote suits the time of sale. Several practical details can move a buyer's actual offer away from the estimate.

• Stones and non-gold parts: gems, steel springs, watch movements, heavy clasps, and other inserts reduce recoverable gold weight.
• Hallmark accuracy: stamps help identify purity but can be affected by plating, repairs, or lower-karat solder.
• Mixed lots: combining 10k and 18k pieces in one entry hides their different gold contents. Sort by purity where possible.
• Market timing: gold prices move during the day, so a morning estimate can differ from an afternoon quote.
• Dealer policies: buyers may pay differently for larger, cleaner, sorted, or uncertain lots.
• Rounding: the displayed figures are rounded for readability, so small differences are expected.

Do not treat gold-plated or gold-filled items as solid-karat scrap gold. They may have a gold-colored surface while containing little recoverable gold. Another common error is using an ordinary-ounce scale reading as a troy-ounce entry. When there is uncertainty, weighing small jewelry in grams is usually the clearest approach.

This calculator also does not assign repair value, antique value, designer resale value, collectible value, gemstone value, or sentimental value. Some jewelry is worth more when sold intact than when sold for refining, so compare both options for notable pieces.

Bring the scrap gold assumptions to the buyer

Take your scrap-gold estimate along with the information behind it: weight, karat, selected unit, and spot price. Understanding that a 20-gram 18k bracelet contains more pure gold than a 20-gram 10k bracelet is more useful than memorizing a single result. With those inputs in hand, you can compare offers more confidently as market prices change.
