Gold Price Calculator
Gold price calculator that converts live or scenario spot into the price for your grams, DWT, or ounces, with karat purity applied to the metal on your scale.

Current 14K price · —/gram · —/10g · —/oz
Using live market spot for this calculation.
Formula: weight × karat multiplier × spot price. 14K = 0.583
Spot is quoted per troy ounce of fine gold. Your scale shows something else—maybe 12.4 grams of 14K, maybe 8 DWT of 10K. Those two worlds don’t meet until someone converts units and purity.
That’s when napkin math fails. People paste the ounce headline onto karat weight and call it “the gold price.” Then they wonder why every shop in town quotes lower.
This gold price calculator converts a spot basis into the price for your weight and karat so the number on screen matches the metal on the pad.
What “gold price” means on a jewelry scale
Headline spot ≠ cash for your bracelet. On this page, “price” means: given a spot and a purity, what is this weighed piece worth on a melt-style basis?
Inputs that matter:
- Spot (per troy oz fine, or a scenario you type)
- Weight
- Unit (g / DWT / troy oz)
- Karat or purity
Output: a dollar estimate for that line. Not a store tag. Not an appraisal for insurance replacement.
Convert spot without mixing units
Per-gram fine price ≈ spot_per_troy_oz ÷ 31.1035
Karat piece price ≈ weight_g × (karat ÷ 24) × per-gram fine price
DWT path: spot_per_DWT ≈ spot_per_oz ÷ 20, then × purity × DWT weight.
If those steps feel slippery, bookmark pennyweight vs grams vs troy ounce and keep this calculator for the arithmetic.
Practical workflow
- Note the spot you’re using — Live UI spot or a what-if number. Write the time if you’re comparing shops later.
- Weigh the piece dry — Stones out when possible.
- Confirm karat — Stamp first; test when unmarked. Hallmark decode: gold hallmark numbers.
- Enter weight + unit + karat — Let the tool align the spot basis.
- Save the line — If you’re pricing a tray, run one piece type at a time so a bad stamp doesn’t poison the whole total.
- Stack against offers — A cash bid should have a story relative to this number—not match it dollar-for-dollar.
Spot moves; your weight doesn’t
Morning spot and afternoon spot can disagree by enough to change a large lot’s estimate. Recalculate with identical weights when someone says “price dropped.”
You’re checking whether the market moved—or whether the buyer changed purity assumptions. Different problem, different fix.
Price per piece vs price per lot
Running one ring at a time teaches you which items carry the tray. Running the whole lot as one weight hides a gold-filled interloper or a mis-stamped clasp.
Habit that works on busy days: price the weird pieces alone (odd stamps, repairs, suspect color), then batch the boring confirmed 14K together. Your gold price calculator total stays honest without turning every curb link into its own science project.
If the lot is scrap with a shipping date attached, pair this price pass with packing notes from the scrap gold calculator workflow so the dollars still map to bags.
Karat price factors (quick table)
| Karat | × fine price (approx.) |
|---|---|
| 10K | × 0.417 |
| 14K | × 0.583 |
| 18K | × 0.750 |
| 22K | × 0.917 |
| 24K | × 0.999 |
Same weight at 18K is worth more than at 10K because more of each gram is gold. Obvious on paper; easy to forget mid-haggle.
Worked EXAMPLE
EXAMPLE spot: $2,400 / troy oz (illustrative).
Piece: 10 grams of 14K.
Per-gram fine ≈ 2400 ÷ 31.1035 ≈ $77.16.
14K factor ≈ 0.583.
Illustrative price ≈ 10 × 0.583 × 77.16 ≈ $450.
Same piece as ≈ 6.43 DWT: spot per DWT ≈ 2400 ÷ 20 = $120; × 0.583 × 6.43 ≈ $450. Matching units keep both paths honest.

Frequently Asked Questions
Is this the price a pawn shop will pay?
It’s a melt-style reference from your inputs. Local cash bids usually sit under that after testing and margin.
Can I enter a custom spot?
Yes—use scenario prices to stress-test a lot if live spot isn’t what you and the buyer agreed to discuss.
Why convert to grams at all?
Because your scale likely weighs grams or DWT, while headlines scream troy ounces. Conversion is the whole job.
Does purity change the “gold price” or only the value?
Both, in practice. Lower karat means each gram carries less fine gold, so the dollar price for that weighed piece falls.
What about silver mixed in the lot?
This calculator is for gold lines. Dual-metal trays need separate gold and silver math—see the gold and silver calculator.
How often should I refresh spot?
Any time you’re about to accept or reject a number. Stale spot makes clean math look wrong.
Are EXAMPLE prices on this page live?
No. They’re labeled illustrative. The calculator UI is where live spot belongs.
