What Is a Gold Calculator?
A gold calculator is a simple tool that estimates the value of gold based on weight, purity, and gold spot price. This gold value calculator can help you estimate the melt value of gold jewelry, scrap gold, coins, bars, dental gold, and other gold items.
How to Use the Gold Calculator
Enter the weight of your gold item, choose the correct unit, select the karat or purity, enter the current gold spot price in US dollars per troy ounce, and choose a buyer payout percentage. The calculator will estimate the gold melt value, buyer offer, pure gold weight, and value per gram.
Gold Value Formula
The basic formula used by this gold price calculator is: Gold Value = Weight in Troy Ounces × Purity Percentage × Gold Spot Price. For a buyer offer, the calculator multiplies the melt value by the selected payout percentage.
What Is Gold Melt Value?
Gold melt value is the estimated value of the pure gold content inside an item. A gold melt value calculator does not usually include gemstone value, brand value, collectible value, craftsmanship, or retail markup.
How Scrap Gold Value Is Calculated
A scrap gold calculator estimates value by converting the item weight to troy ounces, adjusting for karat purity, and multiplying by the gold spot price. Mixed scrap gold should be calculated row by row because 10K, 14K, 18K, and 22K gold contain different amounts of pure gold.
Gold Price Per Gram Explained
Gold is usually quoted per troy ounce, but many jewelry owners want the gold price per gram. This gold gram calculator converts the spot price into a per-gram price, then adjusts it by purity.
Gold Karat and Purity Guide
Karat measures how much pure gold is in an item. A 24K item is nearly pure gold, while 14K gold is about 58.33% pure gold. A gold karat calculator or gold purity calculator helps convert karat markings into percentage values.
| Stamp | Karat | Gold Purity | Common Use |
|---|---|---|---|
| 999 | 24K | 99.9% | Bullion, coins, pure gold |
| 916 | 22K | 91.67% | Jewelry, coins |
| 750 | 18K | 75% | Fine jewelry |
| 585 | 14K | 58.5% | Common US jewelry |
| 417 | 10K | 41.7% | Affordable US jewelry |
| 375 | 9K | 37.5% | Jewelry |
10K vs 14K vs 18K vs 24K Gold
10K gold has less pure gold but is durable and common in affordable jewelry. 14K gold is popular in the US because it balances value, strength, and appearance. 18K gold has more pure gold and is common in fine jewelry. 24K gold is nearly pure and often used for bullion, coins, and investment gold.
Difference Between Troy Ounce and Regular Ounce
Gold is priced by the troy ounce, not the regular ounce used for many everyday items. One troy ounce equals 31.1034768 grams, while one regular ounce equals 28.349523125 grams.
How Much Is 14K Gold Worth?
To estimate 14K gold value, multiply the gold spot price by 58.33% and then adjust for weight. A 14k gold calculator is useful for rings, chains, bracelets, earrings, and scrap jewelry.
How Much Is 18K Gold Worth?
18K gold is 75% pure gold. An 18k gold calculator multiplies the item weight by 75% purity and the current spot price to estimate melt value.
Why Gold Buyers May Pay Less Than Melt Value
Pawn shops, jewelers, refiners, and cash for gold buyers may pay less than full melt value because they have testing costs, refining costs, business expenses, and profit margins. This is why the buyer payout percentage is included in this cash for gold calculator.
Gold Jewelry Value vs Resale Value
A gold jewelry value calculator estimates the metal value of jewelry. Resale value may be higher or lower depending on brand, design, gemstones, condition, market demand, and whether the item is sold as jewelry or scrap gold.
Gold Coin and Bullion Value
Gold coins and bars may trade close to spot price, but premiums can apply. Collectible coins may have numismatic value beyond gold content. For bullion, purity and exact weight are especially important.
Tips Before Selling Gold in the US
Check the current spot price, weigh your gold carefully, understand the karat stamp, compare multiple offers, ask about fees, and avoid selling without knowing the approximate melt value. This scrap gold value calculator gives you a useful starting estimate before visiting a buyer.
Common Gold Stamps and Meanings
Common markings include 999 for 24K, 916 for 22K, 750 for 18K, 585 for 14K, 417 for 10K, and 375 for 9K. These stamps show the approximate gold purity of the item.
Gold Calculator Examples
Example 1: 14K Gold Jewelry
For 14K gold jewelry weighing 20 grams with a gold spot price of $2,400 per troy ounce, convert 20 grams to troy ounces, multiply by 58.33%, and then multiply by $2,400.
Example 2: 18K Gold Necklace
For an 18K gold necklace weighing 35 grams with a buyer payout of 90%, calculate the melt value using 75% purity, then multiply the result by 90% to estimate the buyer offer.
Example 3: Mixed Scrap Gold
For mixed scrap gold items with different karats, add each item separately. A 10K ring, 14K bracelet, and 18K necklace should each be calculated with its own purity value.
