What is Scrap Gold?
If you have a broken necklace, an outdated wedding band, an old gold tooth crown, or bent earrings, you possess what the jewelry industry calls "scrap gold." Scrap gold is any item containing gold that is no longer valued for its design or craftsmanship. Instead, its value is based entirely on its raw metal content.
When you take these items to a pawn shop or a "cash for gold" business, they do not care about the brand or how pretty it looks. They are going to melt it down to extract the pure 24K gold and sell it to a refinery. Because of this, you must use a highly accurate scrap gold value calculator to ensure you are getting a fair price based on today's Estimated commodity market, rather than a lowball guess from a buyer.
How to Use the Scrap Gold Value Calculator
Finding your exact gold melt value is easy if you follow these four steps before walking into a jewelry store:
- Weigh Your Gold: Use a digital kitchen scale or a pocket scale. Our tool acts as a gold per gram calculator or a pennyweight gold calculator depending on what unit your scale uses. Note: If your jewelry has diamonds or heavy stones, the buyer will subtract that weight.
- Find the Purity (Karat): Look for a tiny stamp on the clasp of a necklace or the inside of a ring. You will likely see "14K", "10K", or "18K". In Europe, you might see numbers like "585" (which is 14K) or "750" (which is 18K). Select this in the calculator.
- Check the Estimated Spot Price: Gold is a traded commodity, meaning the price changes every second. You can search "Gold spot price today" on Google to find the current price per Troy Ounce and enter it here.
- Set the Payout Percentage: No buyer will pay you 100% of the melt value. They have to pay for smelting, refining, and business overhead. A fair payout is between 75% and 85%. Enter 80% to get a realistic cash estimate.
Hitting calculate instantly processes the complex math, showing your raw value and what you should accept in cash.
The Gold Melt Value Formula Explained
If you want to know how pawn shops calculate their offers, or if you want to verify our calculate scrap gold price tool by hand, here is the universal jewelry industry formula.
Why Do We Divide by 24?
Pure gold is 24 Karats. If your ring is 14K, it is not pure gold; it is mixed with copper, silver, or zinc to make it harder. By dividing 14 by 24, we get 0.583 (or 58.3%). This means your ring is exactly 58.3% pure gold, and 41.7% cheap alloy metals. You only get paid for that 58.3%.
Additionally, you must be careful with weight. A standard kitchen ounce (Avoirdupois) is 28.35 grams. But gold is measured in Troy Ounces, which are heavier at 31.103 grams. Our spot price of gold calculator handles these confusing conversions in the background for you automatically.
Understanding Gold Karats & Purity
Not all gold is created equal. Knowing your karat is the most critical step before using a cash for gold calculator online.
24K & 22K Gold (Investment & Asian Jewelry)
24K is 99.9% pure gold. It is incredibly soft and bright orange-yellow. It is rarely used in jewelry because it bends too easily, but is standard for investment coins and bullion bars. 22K (91.6% pure) is very common in high-end jewelry from India, the Middle East, and Southeast Asia.
18K & 14K Gold (Standard Fine Jewelry)
18K (75% pure) is the global standard for luxury jewelry and watches (like Rolex). 14K (58.3% pure) is the absolute standard in the United States for engagement rings and daily wear necklaces because it perfectly balances value, beautiful color, and scratch resistance.
10K & 9K Gold (Discount & Vintage Jewelry)
10K (41.7% pure) is the minimum purity that can legally be sold as "gold" in the United States. It is very hard and durable. 9K (37.5% pure) is common in vintage jewelry from the UK and Australia. These have lower melt values but hold up exceptionally well over decades.
Gold Karat Purity & Value Chart
Use this reference table to quickly identify hallmarks on your jewelry and understand how much pure gold is actually in the item you are trying to sell.
| Karat (K) | Millesimal Hallmark | Pure Gold Content | Other Metals (Alloy) | Common Uses |
|---|---|---|---|---|
| 24K | 999 | 99.9% | 0.1% | Gold bars, coins, bullion |
| 22K | 916 | 91.6% | 8.4% | Indian & Middle Eastern jewelry |
| 18K | 750 | 75.0% | 25.0% | Luxury watches, fine jewelry |
| 14K | 585 | 58.3% | 41.7% | Standard US engagement rings |
| 10K | 417 | 41.7% | 58.3% | Class rings, discount jewelry |
| 9K | 375 | 37.5% | 62.5% | British vintage jewelry |
*Note: If your jewelry says "GF" (Gold Filled), "GP" (Gold Plated), or "HGE" (Heavy Gold Electroplate), it is NOT solid gold. A scrap calculator will not work for these items as the gold content is microscopically thin.
Real-World Examples: Selling Your Gold
Let's see how regular people use our sell gold jewelry calculator to avoid getting ripped off by local dealers.
💍 Example 1: Selling an Old Wedding Ring
Mark has a 14K gold wedding band that weighs 8 grams. The spot price of gold today is $2,300 per ounce.
🏅 Example 2: Grandfather's Coin Collection
Sarah inherited a heavy 22K gold coin. She takes it to a jeweler, who weighs it at 1.5 Troy Ounces.
🦷 Example 3: Scrap Dental Gold
David kept his old gold crown after dental surgery. It weighs 4 pennyweights (dwt) and tests at 10K purity.
Tips to Get the Highest Cash Payout
If you have used the scrap gold price per gram calculator and know your number, here is how to get as close to that number as possible:
- Shop Around: Never take the first offer. Go to three different pawn shops or jewelers. Take out your phone, show them the calculator results, and ask them what their payout percentage is. Competition forces them to give you a fairer price.
- Separate Your Karats: If you have a pile of mixed jewelry, sort the 10K, 14K, and 18K into different bags. If a dishonest dealer weighs it all together in one pile, they will calculate the entire batch at the lowest 10K price!
- Sell to Refineries Directly: If you have a large amount of gold (over 2 or 3 ounces), skip the pawn shop and mail it directly to a professional metal refinery. Refineries usually offer 90% to 95% payouts, cutting out the middleman entirely.

Frequently Asked Questions (FAQ)
Answers to the internet's most common questions about selling jewelry, testing gold, and understanding spot prices.
What is scrap gold?
Scrap gold refers to any gold item—like broken jewelry, mismatched earrings, dental crowns, or old coins—that is meant to be melted down and recycled rather than sold for its original manufactured value or design.
How does a scrap gold value calculator work?
It takes the weight of your item, converts it to standard troy ounces, multiplies it by the gold purity (Karat percentage), and then multiplies that by the current gold spot price to find the absolute maximum melt value.
What is the difference between Melt Value and Payout Value?
Melt Value is the raw mathematical value of the pure gold content based on global spot prices. Payout Value is the actual cash a dealer or pawn shop will give you, usually 70% to 85% of the melt value, keeping the rest as their profit margin.
What is a pennyweight (dwt)?
A pennyweight (abbreviated as dwt) is a traditional unit of weight used almost exclusively by jewelers. One pennyweight equals 1.555 grams, and there are exactly 20 pennyweights in a single Troy Ounce.
What is the difference between a Standard Ounce and a Troy Ounce?
A standard kitchen (Avoirdupois) ounce weighs 28.35 grams. Precious metals are weighed in Troy Ounces, which are slightly heavier at 31.103 grams. Always ensure you select the correct ounce type in the calculator so you aren't underpaid!
How do I know the karat of my gold?
Most real gold jewelry is stamped with a hallmark indicating its purity, such as 14K, 18K, 417, 585, or 750. If there is no stamp or it has worn off, a jeweler can perform a fast acid test or electronic test to determine the exact karat.
Is 24K gold 100% pure?
Yes, 24 Karat gold is considered 99.9% to 100% pure gold with no other alloy metals mixed in. It is the most valuable but also very soft and easily dented, which is exactly why wearable jewelry is usually alloyed down to 14K or 18K.
Do stones or gems add to the scrap weight?
No. When selling gold for scrap, the buyer will estimate and subtract the weight of any diamonds, cubic zirconia, stones, or non-gold metal springs inside the clasp. You only get paid for the actual gold metal weight.
Why is the spot price constantly changing?
Gold is a globally traded commodity, just like oil or coffee. Its price fluctuates every single second the markets are open based on supply, demand, inflation data, US Dollar strength, and global economic stability.
How much do pawn shops usually pay for gold?
Most standard pawn shops or "cash for gold" kiosks will offer you between 60% and 75% of the melt value. Professional jewelers or direct refineries will usually pay much higher, ranging from 80% to 95% depending on the volume of gold you have.
