What today’s spot means per gram.
UPDATED … ETPer-gram melt values track the live spot price and each karat’s gold purity. DD Pawn Loans pays cash on the spot for gold, silver, diamonds, and luxury watches in Pompano Beach, Fort Lauderdale, and across Broward County — or offers a short-term collateral loan so you keep the piece.
How a pawn shop gold calculator works
Every gold buyer and pawn shop prices gold the same way: weight × purity × today's spot price per gram. The spot price is the world market price for one troy ounce (31.1 g) of pure gold. Your jewelry is rarely pure, so the karat stamp tells us how much of each gram is actually gold. The calculator above pulls the live spot price, applies the purity for the karat you pick, and shows the math line by line.
- Weigh the gold. Grams are standard; pennyweight (dwt) is 1.555 g and a troy ounce is 31.1 g. Stones, clasps, and springs are deducted.
- Confirm the karat. We acid-test and electronically test every piece on camera, so a worn or missing stamp does not cost you anything.
- Multiply by purity. 14K is 58.3% gold, so 10 g of 14K holds 5.83 g of pure gold.
- Apply today's spot per gram. That gives the melt value shown in the card above.
- Get the offer. We pay up to 90% of melt in cash, or lend against the piece so you keep it.
Gold purity by karat
| KARAT | PURITY | PURE GOLD | TYPICAL USE |
|---|---|---|---|
| 10K | 41.7% | 0.417 g per gram | Most durable; common in chains and bracelets |
| 14K | 58.3% | 0.583 g per gram | The most common karat in US jewelry |
| 18K | 75.0% | 0.750 g per gram | Richer color; fine and designer pieces |
| 22K | 91.7% | 0.917 g per gram | Common in Indian and Middle Eastern jewelry |
| 24K | 99.9% | 0.999 g per gram | Pure gold; bars, coins, and bullion |
Worked example: a 7.3 g 14K chain contains 7.3 × 0.583 = 4.26 g of pure gold. Multiply 4.26 g by today's spot price per gram (shown at the top of this page) for the melt value; our cash offer is up to 90% of that figure, confirmed at appraisal.
Gold calculator questions
How much is 14K gold worth per gram at a pawn shop?
14K gold is 58.3% pure, so one gram of 14K contains 0.583 g of pure gold. Multiply that by today's spot price per gram to get the melt value, then expect a cash offer of up to 90% of melt. The calculator above does this with the live spot price.
What is the difference between a gold calculator and a pawn calculator?
A gold calculator shows the melt value of your gold from its karat and weight. A pawn calculator shows what you can borrow against an item while you keep ownership. This page shows both: the melt value, our cash-buy range, and our collateral-loan range.
Do pawn shops pay the full spot price for gold?
No buyer pays 100% of spot, because the gold still has to be tested, refined, and resold. DD Pawn Loans pays up to 90% of melt value in cash, with the final number set at a filmed, certified appraisal.
Do stones, clasps, and plating count toward the weight?
No. Only the gold itself is weighed. Diamonds and gemstones, steel springs in clasps, and any non-gold parts are deducted, and gold-plated or gold-filled pieces are not priced as solid gold.
How accurate is this estimator?
The spot price refreshes about every 60 seconds and the math is shown step by step. It is an estimate, not an offer: the final price depends on professional testing of purity, weight, and condition. Bring the piece in, or lock the estimate and we will open your free insured kit on camera.
