Use Cases
Selling Scrap Gold
Determine the base melt value of gold jewelry or coins before approaching a buyer, so you know the minimum worth based on current spot price.
Example: A 14k gold chain weighing 20 grams with spot at $2,000/oz gives a melt value of about $1,333.
Buying Gold Items
Check if the asking price for a gold item is reasonable by comparing it to the melt value, helping you avoid overpaying for the gold content.
Example: If a 22k coin weighs 33.9g and spot is $1,900/oz, melt value is roughly $2,100.
Frequently Asked Questions
- How does the Gold Melt Value Calculator work?
- Enter the total weight of your gold item, select its purity (e.g., 24k, 22k, 18k, 14k, 10k), and input the current spot price per troy ounce. The calculator multiplies the weight by the purity fraction to find the fine-gold weight, then multiplies that by the spot price to estimate the melt value.
- What is fine-gold weight?
- Fine-gold weight is the actual amount of pure gold in an item, calculated by multiplying the total weight by the purity percentage. For example, a 10-gram 18k item (75% gold) contains 7.5 grams of fine gold.
- Does the calculator account for wear, damage, or dealer fees?
- No, it provides an estimate based on the weight, purity, and spot price you enter. Actual buy or sell prices may be lower due to refining costs, dealer margins, or wear. Use this as a reference, not a final offer.
Tips & Common Mistakes
Tips
- Use a precise scale that measures in grams or troy ounces for accurate weight input.
- Verify the purity of your gold item—look for hallmarks like 24k, 18k, or 14k, or get it professionally tested.
- Check the live spot price from a reliable source just before calculating, as gold prices fluctuate throughout the day.
- Remember that the result is the melt value; actual offers may be lower due to refining and dealer costs.
Common Mistakes to Avoid
- Using the total weight as if it were pure gold, ignoring the purity percentage, which overestimates the value.
- Entering the spot price per gram instead of per troy ounce, leading to incorrect results.
- Forgetting that the calculator gives an estimate, not a guaranteed payout, and expecting the exact melt value in a sale.
