Using live market spot for this calculation.
Formula: weight × karat multiplier × spot price. 14K = 0.583
Fourteen karat is the workhorse alloy in a lot of U.S. jewelry cases. Stamped 14K or 585, it’s about 58.3% gold—strong enough for daily wear, soft enough that scrap trays fill up with it.
If you price 14K like 18K, you’ll overstate. If you treat every yellow piece as “around 14,” you’ll bury the higher-karat items and overpay the lower ones in your head.
This 14K gold calculator locks purity near 58.3% and lets you run grams, DWT, or troy ounces against spot without redoing the karat math each time.
14K purity in one line
14K ≈ 14 ÷ 24 ≈ 0.5833 (58.3%). Hallmark 585 means ~585/1000 fine.
Melt-style value ≈ weight × 0.583 × gold price (matching units).
That’s the whole trick. Everything else is unit hygiene and honest weighing.
Run 14K on the unit your scale uses
Grams:
per-gram fine price ≈ spot_oz ÷ 31.1035
14K $/g ≈ per-gram fine × 0.583
value ≈ weight_g × 14K $/g
DWT:
spot_per_DWT ≈ spot_oz ÷ 20
value ≈ weight_DWT × 0.583 × spot_per_DWT
Troy oz (of 14K alloy, not fine):
value ≈ weight_oz × 0.583 × spot_oz
Confused on units? Keep pennyweight vs grams vs troy ounce open beside the tool.
Bench steps for 14K lots
- Confirm the stamp — 14K, 14Kt, 585. Worn marks need a loupe or a test.
- Sort true 14K from lookalikes — 10K and gold-filled sneak into “14K trays.”
- Pull stones and steel — Dead weight is the quiet estimate killer.
- Weigh the 14K group alone — Don’t blend with 18K “to save time.”
- Calculate — Use this page’s purity default; override only if assay says otherwise.
- Watch under plumb — Some older goods assay light of stamp. Context: half karat under plumb.
14K vs nearby karats
| Stamp | Approx. gold | Relative to 14K (same weight) |
|---|---|---|
| 10K / 417 | ≈ 41.7% | Lower — roughly 0.72× of 14K value |
| 14K / 585 | ≈ 58.3% | Baseline |
| 18K / 750 | ≈ 75% | Higher — roughly 1.29× of 14K value |
Same chain weight at 18K pays more metal; same weight at 10K pays less. The calculator won’t fix a mis-sorted tray.
Worked EXAMPLE
EXAMPLE spot: $2,400 / troy oz (illustrative).
Lot: 40 grams of 14K.
Fine grams ≈ 40 × 0.583 = 23.32 g.
Fine oz ≈ 23.32 ÷ 31.1035 ≈ 0.750 oz.
Illustrative melt-style ≈ 0.750 × $2,400 = $1,800.
Per-gram 14K price at that EXAMPLE spot ≈ 2400 ÷ 31.1035 × 0.583 ≈ $45.00/g. Handy for quick tray math—still not a cash offer.
When 14K math isn’t enough
Gold-filled marked “1/20 14K” is not 58.3% of the whole piece. Use the gold filled calculator.
Broken jewelry headed out as scrap still benefits from a packing list mindset—see the scrap gold calculator and maximize scrap refining payout.
14K scrap habits from the counter
Most U.S. scrap trays skew 10K and 14K. That makes 14K feel “normal,” which is exactly when people stop double-checking stamps.
Slow down on:
- Partial stamps — “14” without K, or a mashed 585. Test before you commit a big line.
- Mixed white and yellow — Same karat fraction if the stamp matches; still sort if you’re unsure one side is plated.
- Heavy galeros / hollow softballs — Looks like weight, isn’t. Trust the scale.
- Repair solder — A resized ring can carry different alloy at the seam. Small on one ring; loud on a pound of repairs.
If you’re comparing a cash offer on a pure 14K lot, stack it against this calculator’s melt-style number and ask what purity they paid. Process notes: the cash for gold calculator page.

Frequently Asked Questions
How much is 14K gold worth per gram?
Take spot per troy oz, divide by 31.1035, multiply by ~0.583. The calculator does that with live or scenario spot.
Is 585 the same as 14K?
Yes—585 parts per thousand ≈ 14K.
Why didn’t my buyer pay the calculator number?
They’re buying scrap with risk and overhead, not settling textbook melt.
Can I use this for 14K gold-filled?
No. The recoverable fraction is much smaller than solid 14K.
Do stones in a 14K ring count?
They add weight, not gold. Remove or discount them.
Grams or DWT for 14K scrap?
Whichever your scale shows—just match the spot conversion.
What if the piece says 14K but assays lower?
Pay and settle on assay when that’s the deal. Stamps can be wrong or under plumb.
