Understanding Melt Value: What Your Gold & Silver Is Really Worth
Whether you're buying your first coin or evaluating an old piece of jewelry, melt value is the number that matters most. It tells you what the metal itself is worth, separate from collectible premiums, dealer markups, or brand names.
What Is Melt Value?
Melt value is the value of the precious metal contained in an item, based on its weight, purity, and current spot price. The formula:
Melt Value = Weight (troy oz) × Purity × Spot Price
It's worth knowing how melt value differs from a few other numbers you'll run into:
- Spot price is the per-ounce market rate for pure metal. It's a benchmark price, not the price of any specific coin or bar.
- Retail price is what a dealer charges. That includes melt value plus a premium for manufacturing, distribution, and profit.
- Numismatic value is what collectors will pay, which is driven by rarity, condition, and history rather than metal content. It can be far above melt, or occasionally below it for common coins in worn condition.
For anyone focused on bullion, melt value is the baseline. It's the floor below which no rational buyer should pay less, and the anchor for evaluating whether a premium is worth it.
Spot Price vs. Melt Value
Spot price is the current market price for one troy ounce of pure metal. It updates throughout the trading day based on global supply and demand.
Melt value is what the metal in your specific item is worth after accounting for its purity. A 14K gold ring doesn't contain a full ounce of pure gold. It's 58.33% gold, so its melt value is a fraction of the gold spot price.
Spot price tells you what an ounce of pure gold costs right now. Melt value answers a different question: how much pure gold is in this item, and what is that gold worth?
How Melt Value Is Calculated
Melt Value = Weight (troy oz) × Purity × Spot Price
Gold Karat Purities
Gold jewelry and coins come in standard karat purities. Each karat represents a fraction of pure gold out of 24 parts:
- 24K – 99.9% pure (1.000)
- 22K – 91.67% pure (0.9167)
- 18K – 75.0% pure (0.750)
- 14K – 58.33% pure (0.5833)
- 10K – 41.67% pure (0.4167)
Silver Purities
Silver comes in a few common purities depending on what you're looking at:
- .999 fine – bullion bars and rounds
- .925 sterling – jewelry and flatware
- .900 coin silver – pre-1965 US dimes, quarters, and half dollars
- .800 – some European silver coins and items
Worked Example
Say you have a 14K gold ring that weighs 4 grams, and the current gold spot price is $2,000 per troy ounce.
- Convert grams to troy ounces: 4 ÷ 31.1035 = 0.1286 troy oz
- Apply purity: 0.1286 × 0.5833 = 0.0750 troy oz of pure gold
- Multiply by spot price: 0.0750 × $2,000 = $150.02
That ring has about $150 worth of gold in it at a $2,000 spot price. If spot climbs to $3,000, the same ring is worth $225 in metal alone.
Weight Units
This is where a lot of people get tripped up. Precious metals use troy ounces, not the everyday ounce you find on a food label.
- Troy ounce (ozt) = 31.1035 grams
- Avoirdupois ounce (oz) = 28.3495 grams
A troy ounce is about 10% heavier than a standard ounce. If you weigh gold on a kitchen scale that reads in avoirdupois ounces and plug that number into a melt value calculation expecting troy ounces, your result will be about 10% too high.
Other units you may come across:
- Pennyweight (dwt) – 20 dwt per troy oz. Common in the US jewelry trade.
- Grain – 480 grains per troy oz. An older unit still occasionally used.
- Kilogram (kg) – used for large bars. A London Good Delivery gold bar is roughly 400 troy oz (about 12.4 kg).
When in doubt, weigh in grams and divide by 31.1035 to get troy ounces.
Premium Over Melt
When you buy bullion, you almost always pay more than melt value. That difference is the premium.
Premium = Purchase Price − Melt Value
Premiums cover manufacturing costs, dealer margins, and market demand. They vary quite a bit depending on what you're buying:
- Government-minted coins (American Eagles, Canadian Maple Leafs, etc.) carry higher premiums than generic products, partly due to demand and partly because they're harder to counterfeit.
- Generic rounds and bars from private mints trade closer to melt and typically carry lower premiums than sovereign coins.
- Junk silver (pre-1965 US coins) tends to have some of the lowest premiums in the silver market and is widely traded.
Premiums aren't fixed. They go up when demand spikes or supply is tight, and they compress during quieter markets. Keeping an eye on premiums over time helps you spot good buying opportunities.
Calculating Melt Value in Gold Tracker
Gold Tracker's built-in calculator handles all of this automatically. Pick a karat purity, enter a weight in any unit (grams, troy ounces, pennyweights, or grains), and it calculates melt value against live spot prices.
