> The scrap gold calculator works out how much your scrap gold is worth – by karat, weight and current gold price – mixing up to three different karats, and the amount a buyer is likely to pay at their payout percentage.

## Inputs

- 10K gold weight (grams, troy ounces, ounces (avoirdupois), pennyweights (dwt), tola, kilograms)
- 14K gold weight (grams, troy ounces, ounces (avoirdupois), pennyweights (dwt), tola, kilograms)
- 18K gold weight (grams, troy ounces, ounces (avoirdupois), pennyweights (dwt), tola, kilograms)
- 22K/24K gold weight (grams, troy ounces, ounces (avoirdupois), pennyweights (dwt), tola, kilograms)
- Gold price per troy ounce
- Buyer's payout (%)

## Results

- Pure gold content
- Melt value
- Expected offer

## Formula

```
Pure gold = Σ weight × purity
Melt value = pure gold (troy oz) × spot price
Offer = melt value × payout %
```

## Explanation

Separate pieces by karat before selling so you get paid for each purity correctly. Check the stamp (10K, 14K, 585, 750 …) and get quotes from several buyers – payouts range from about 70% to 95% of melt value.
