How Gold Melt Value Is Calculated

Gold melt value is the dollar amount your gold is worth based purely on its metal content. It ignores brand names, design, age, and sentimental value. It answers one question: if this gold were melted into a pure bar, what would it sell for today?

Melt value is the baseline number you need before selling any gold. It tells you the floor price. No legitimate buyer should offer you less than a fair percentage of this number. If they do, walk away.

The Formula

Three numbers determine the melt value of any gold item:

Weight (in grams) × Purity (as a decimal) × Gold Spot Price (per gram)

That gives you the melt value in dollars. Let's walk through each piece.

Step 1: Weigh Your Gold

You need the weight in grams. Most kitchen scales work fine for a rough estimate, but a digital jewelry scale accurate to 0.01 grams is better. You can pick one up for under $15 online.

Weigh just the gold. If your item has stones, clasps made of other metals, or non-gold components, keep in mind that total weight is not the same as gold weight. A buyer will deduct for non-gold materials.

Step 2: Determine the Purity

Gold purity is measured in karats. Pure gold is 24K. Most jewelry is not pure. The karat stamp tells you what percentage of the item is actual gold.

Look for a small stamp on the inside of a ring band, on a clasp, or on the back of a pendant. Common stamps include 10K, 14K, 18K, and 24K. Some pieces use a three-digit fineness number instead, like 585 (which is 14K) or 750 (which is 18K).

Here's the conversion chart:

If your piece has no stamp, a gold buyer can test it with an acid kit or an XRF machine. Don't assume it's gold just because it looks gold.

Step 3: Check the Spot Price

The gold spot price is the current market price for one troy ounce of pure gold. It changes throughout the day based on global trading. You can check it on any financial site or right here on MeltValue.com.

To use the formula, you need the spot price per gram, not per ounce. One troy ounce equals 31.1035 grams. So divide the spot price by 31.1035 to get the per-gram price.

For example, if gold is trading at $3,000 per troy ounce, the price per gram is $3,000 ÷ 31.1035 = $96.45 per gram. Our calculator does this conversion automatically.

Putting It All Together

Let's say you have a 14K gold chain that weighs 15 grams, and today's gold spot price is $3,000 per ounce.

• Step 1: Weight = 15 grams
• Step 2: Purity = 0.583 (14K)
• Step 3: Spot price per gram = $3,000 ÷ 31.1035 = $96.45

Melt value = 15 × 0.583 × $96.45 = $843.44

That's the pure gold value of your chain at today's market price. A buyer will typically offer somewhere between 70% and 90% of this number, depending on who you sell to and the current market.

What Melt Value Does Not Include

Melt value is just the gold content. It does not account for:

Craftsmanship or brand. A Tiffany ring and a no-name ring with the same weight and karat have the same melt value. But the Tiffany ring may be worth more on the resale market because of the brand. If your piece has designer value, consider getting an appraisal before selling it for scrap.

Gemstones. Diamonds, rubies, and other stones in your jewelry are not part of the melt value calculation. Some buyers will offer separately for stones; others ignore them completely.

Numismatic or collector value. Gold coins can be worth significantly more than their melt value if they are rare, old, or in exceptional condition. A common American Gold Eagle trades close to melt. A rare 1907 High Relief Saint-Gaudens could be worth many times melt. Know what you have before selling.

Why This Number Matters When Selling

Knowing the melt value before you walk into a gold buyer's shop changes the entire dynamic. You're not guessing. You're not hoping they're honest. You have a number.

If a buyer offers you 60% of melt value, you know that's a lowball offer. If another buyer offers 85%, you know that's competitive. The melt value is your leverage.
