How to Use the Gold Price Calculator
Weigh your gold on a gram scale (kitchen scales work for a rough estimate, but a jeweler's scale is more precise). Find the karat stamp on the piece — common stamps include 10K, 14K, 18K, 22K, 24K, or the numeric equivalents 417, 585, 750, 916, and 999. Enter both values into the calculator above.
The calculator shows the melt value, which is what the pure gold content of your item is worth at today's spot price. Actual dealer offers will be a percentage of this melt value — typically 70% to 95% depending on the buyer, purity, quantity, and form of the gold.
Gold Price Per Gram by Karat
| Karat | Purity | Price / Gram | Change |
|---|---|---|---|
| 24K | 99.9% | $146.81 | ▲ +$1.78 (+1.23%) |
| 22K | 91.7% | $134.58 | ▲ +$1.63 (+1.23%) |
| 18K | 75.0% | $110.11 | ▲ +$1.33 (+1.23%) |
| 14K | 58.3% | $85.64 | ▲ +$1.04 (+1.23%) |
| 10K | 41.7% | $61.17 | ▲ +$0.74 (+1.23%) |
Where to Find the Karat Stamp on Your Gold
Rings have the stamp on the inside of the band. Chains and necklaces have it on or near the clasp — look for a small tag. Earrings are stamped on the post or backing. Bracelets are stamped on the clasp or on the inside surface. Watch cases have the karat marked on the case back.
If there is no stamp, the piece may still be gold — older items and foreign-made jewelry sometimes lack stamps. A jeweler or gold buyer can test it with an acid test kit or an XRF (X-ray fluorescence) analyzer to determine the exact karat. Do not assume unmarked items are a particular purity.
Melt Value vs What Dealers Pay
The calculator above shows the melt value — the theoretical value of the pure gold content at today's spot price. This is the starting point for any gold transaction. Dealers deduct their margin from this number to arrive at their offer.
Most reputable dealers pay 70–95% of melt value depending on the karat, form, and quantity. 24K bars and coins get the highest payout (90–97%). 14K jewelry typically receives 75–85%. 10K scrap may get 70–80%. For detailed scrap pricing, visit our scrap gold price per gram page.
Frequently Asked Questions
How do I calculate the value of my gold?
Weigh your gold in grams, identify the karat (check for a stamp like 10K, 14K, 585, 750, etc.), then multiply the weight by the per-gram price for that karat. The calculator on this page does this automatically using the live spot price.
How much is 10 grams of 14K gold worth?
At today's spot price, 10 grams of 14K gold has a melt value of approximately $$856.41. Dealers typically pay 75–85% of this amount, or roughly $$642.31 to $727.95.
What is gold melt value?
Gold melt value is the worth of the pure gold content in an item at the current spot price. It is calculated by multiplying the item's weight by the price per gram for its karat purity. This is the baseline value — the maximum theoretical worth of the gold before any dealer margin is deducted.
How accurate is a gold calculator?
A gold calculator based on live spot prices is highly accurate for determining melt value. The spot price updates every 60 seconds during market hours. The main variable is the actual payout percentage from a buyer, which ranges from 70% to 95% depending on the buyer, purity, quantity, and market conditions.
