> The gold melt calculator works out the melt value of gold jewellery, coins or bars from the weight (grams, troy ounces, pennyweights, tola), karat or purity and the spot price – plus the price a dealer might pay after their spread.

## Inputs

- Karat
- Custom purity (%)
- Weight (grams, troy ounces, ounces (avoirdupois), pennyweights (dwt), tola, kilograms)
- Gold price per troy ounce
- Dealer spread (%)

## Results

- Purity
- Pure gold content
- Gold price per gram
- Melt value
- Likely dealer offer

## Formula

```
Pure gold weight = weight × purity
Melt value = pure gold weight (troy oz) × spot price per troy ounce
Dealer offer = melt value × (1 − spread)
```

## Explanation

Spot gold is quoted per troy ounce (31.1035 g), not the ordinary ounce. Jewellery is sold above melt value because of craftsmanship, while scrap buyers usually pay 70–90% of melt. Check the current spot price before you sell.

### What each result means

- **Pure gold content** = [Weight]×[Purity]÷100
- **Gold price per gram** = [Gold price per troy ounce]÷31.1034768
- **Melt value** = [Pure gold content]÷31.1034768×[Gold price per troy ounce]
- **Likely dealer offer** = [Melt value]×(1 - [Dealer spread]÷100)

## Worked example

Inputs — Karat: 14K (58.5%); Custom purity: 90 %; Weight: 10 grams; Gold price per troy ounce: $4,000; Dealer spread: 20 %.

Results — Purity = 58.5 %; Pure gold content = 5.85 g; Gold price per gram = $128.60; **Melt value = $752.33**; Likely dealer offer = $601.86.
