What is the difference between scrap gold and melt value?
Scrap gold is the physical metal content in jewelry, broken pieces, or other gold items that are being treated as material rather than as collectibles. Melt value is the estimated value of the fine gold inside that item if it were sold based on its pure metal content at the current spot price. The calculator estimates melt value, which is the usual floor for a scrap sale.
How do you calculate scrap gold value?
Start by converting karat to a purity fraction using karat divided by 24. Multiply the item weight by that purity fraction to get fine-gold weight, convert grams to troy ounces, and multiply by the spot price per troy ounce. That gives you a melt-value estimate before any buyer deductions.
Do I need a live gold price to use the calculator?
The calculator does not fetch a live quote on its own, so you should enter a current spot price from a reliable source. That keeps the estimate aligned with the market day you are comparing against. If the spot price moves later, the result should be refreshed.
Is gold sold by grams or troy ounces?
Both units are used, but precious-metals markets usually quote gold in troy ounces, while jewelry is often weighed in grams. This calculator accepts grams because that is how most people weigh jewelry at home, then converts the fine-gold content into troy ounces for pricing. The conversion matters because a troy ounce is not the same as a regular avoirdupois ounce.
Why do buyers pay less than melt value?
A buyer usually deducts for testing, refining, shipping, inventory risk, and profit margin. If stones, settings, clasps, or non-gold alloy parts have to be removed or separated, the payout can fall further. A quote below melt value is normal; the key question is whether the discount is reasonable and clearly explained.
What does 14K, 18K, or 24K mean?
Karat is a 24-part purity scale for gold. 24K is essentially pure gold, 18K is 18 parts gold and 6 parts other metals, 14K is 14 parts gold and 10 parts other metals, and so on. Lower karat items contain less fine gold per gram, so their melt value is lower at the same spot price.
Does the calculator account for stones, solder, or missing pieces?
No. It assumes the weight you enter is the relevant gold-bearing weight. If a ring has stones, a clasp is missing, or the piece has a lot of non-gold solder or filler, you should subtract those non-gold parts mentally or weigh the item after removal if you want a tighter scrap estimate.
Can 9K or 21K gold be calculated?
Yes. The selector includes 8K, 9K, 10K, 12K, 14K, 18K, 20K, 21K, 22K, and 24K, so you can estimate pieces that do not fall into only the most common US jewelry set. If your item is a less common purity, the same karat math still applies as long as you know the correct karat.
Can coins or bars be worth more than scrap?
Yes. Some coins and bars trade above melt value because buyers pay for mint premium, collectibility, condition, or brand reputation. If you have a coin, bar, or antique piece, treat the calculator as a scrap floor rather than the final answer.
Should I clean the gold before selling it?
A light cleaning can help you read hallmarks and inspect the piece, but it will not change the underlying gold content. Aggressive cleaning is usually unnecessary for a scrap quote and can risk scratching or damaging the item. For a pure melt estimate, the important variables are weight, karat, and spot price, not polish.
What is pennyweight in a scrap gold quote?
Pennyweight, often written as dwt, is a jewelry-trade weight unit equal to one twentieth of a troy ounce. Because gold spot prices are quoted per troy ounce, pennyweight quotes are just another way of expressing the same precious-metals value. The calculator converts pennyweight to grams internally so the karat and spot-price math stays consistent.
How do I compare a buyer offer with melt value?
Divide the buyer offer by the calculator's melt value to see the implied payout percentage. For example, an offer of 425 against a 500 melt-value estimate is 85 percent of melt value. A lower payout is not automatically wrong, but it should reflect clear buyer costs such as testing, refining, handling, shipping, risk, and margin.
Should I calculate mixed-karat jewelry as one lot?
It is usually better to calculate each karat group separately. A 10K ring, 14K chain, and 18K pendant have different fine-gold content per gram, so mixing them into one weight can hide value and make buyer quotes harder to compare. Sort by hallmark when possible, run each group through the calculator, and then add the melt values together.
