22k Gold Calculator
22k gold calculator for 916 melt value from weight and spot. Made for high-karat jewelry, coins, and scrap lots that should not get priced like plain 14K.

Using live market spot for this calculation.
Formula: weight × karat multiplier × spot price. 22K = 0.917
Twenty-two karat shows up on wedding jewelry, some coins, and imports stamped 916. Price it with 14K habits and you hand the other side a gift.
It's soft metal. Prongs bend. Marks rub. People still argue "it's almost pure" while forgetting the 8.3% that isn't gold.
This calculator holds purity near 91.7% (22 ÷ 24) so high-karat weight gets high-karat math.
916 isn't "close enough to 24K"
| Karat | Approx. purity | Common mark |
|---|---|---|
| 22K | ≈ 91.7% | 916 |
| 24K | ≈ 99.9% | 999 |
That gap looks small on a chart. On a 30 g bracelet at a busy spot, it's real dollars. Don't round 22K up to "pure" in your head.
Some jurisdictions allow slight tolerance under stamped fineness. If your lots assay light often, read half karat under plumb before you promise a customer the full calculator line.
Counter workflow for 22K lots
Sort first. 22K next to 18K in one bag is how averages lie.
Weigh dry. Soft gold picks up solder and repair patches more than people admit — note anything that looks rebuilt.
Enter weight in the unit on the scale face. Apply ≈ 0.917 purity. Compare offers to that melt-style floor, not to retail sticker nostalgia.
Coins stamped 22K need a second look: melt floor vs collector premium. Use this tool for metal; use a coin specialist before you scrap dates that trade hot. The gold coin melt calculator separates those conversations.
EXAMPLE — 15 g of confirmed 22K
EXAMPLE spot: $4,000 / troy oz (illustrative).
Pure gram ≈ $128.60.
22K gram ≈ 128.60 × (22/24) ≈ $117.88.
Lot: 15 g solid 22K, stones removed.
Fine gold ≈ 15 × 0.9167 ≈ 13.75 g
Melt-style ≈ 13.75 × 128.60 ≈ $1,768.
Same grams at 18K (0.75) would print ≈ $1,445. Mis-stamping karat by one common step swings hundreds on a small lot.
Mistakes that show up on 22K tickets
- Treating 916 jewelry as bullion 999 without checking.
- Leaving heavy gem clusters in the weigh — soft bezels hold big stones.
- Mixing 21K / 22K / 18K "because they're all high."
- Expecting retail replacement cost from melt math.
- Ignoring that some "22K" fashion pieces are plated lies.

Frequently Asked Questions
What purity is 22K?
About 91.7% gold (22 ÷ 24). 916 is the usual fineness stamp.
Is 22K the same as pure gold?
No. Roughly 8.3% of the weight is other metal. 24K / 999 is the near-pure lane.
Can I scrap 22K coins with this?
For melt floor, yes — weight × fineness × spot. Check numismatic value separately before you melt anything with a date premium.
Why do offers trail my 22K estimate?
Assay risk, refining charges, and margin. Soft, repaired jewelry widens that gap. Ask for their accountability terms — background in accountability vs treatment charge.
Grams or ounces?
Both work. Match units to spot. Troy ounces for bullion-style talk; grams for jewelry scales.
What if there's no stamp?
Don't assume 22K from color. Test or assay. Yellow soft metal without marks is a scenario, not a fact.
Disclaimer
Assumes solid 22K near 91.7% unless you set another purity. Educational melt-style estimates — not settlement.
