## About this calculator

Gold's melt value is its pure-gold content priced at the current spot rate. Multiply the item's weight by its purity — karat ÷ 24, so 22-karat is 91.7% gold — then by the gold price. A 10-gram 22K chain holds 9.17 g of pure gold, worth about $1,150 when gold trades near $3,900 per troy ounce. Enter your weight, karat or fineness, and today's price (fetch it live or type it) to value jewellery, coins, bars, or scrap in any currency.

## How to read your results

The headline figure is the melt value — what the pure gold in your item is worth at the price you used, before any dealer margin. Below it, the pure-gold content is shown in grams, troy ounces, and tola, and your purity is expressed three ways (karat, millesimal fineness, and percent) so a "916" stamp and "22K" read as the same thing. The bar chart compares your weight across common karats, so you can see how much purity drives value. If you enter a buyer's offer percentage, the payout row shows what a dealer paying that share of melt would actually hand you.

## How it's calculated

Weight is converted to grams with exact constants: 1 troy ounce = 31.1034768 g, 1 (standard) tola = 11.6638038 g, 1 pennyweight = 1.55517384 g, 1 grain = 0.06479891 g. Purity becomes a fraction — karat ÷ 24, fineness ÷ 1000, or percent ÷ 100 — and pure gold content = weight in grams × that fraction. Melt value = pure grams × spot price per gram, where the spot price is converted from your chosen unit (per troy ounce, gram, or tola). The value math uses the exact karat fraction (22K = 22⁄24 = 91.67%); the fineness shown as a stamp uses the hallmark convention (22K → 916, 14K → 585), which differs slightly from the exact figure because stamps are rounded by agreement, not arithmetic. Making charges, collector premiums, and resale margins are excluded — this is intrinsic metal value only.

**Gold karat, fineness, and purity reference**

| Karat | Millesimal fineness | Pure gold | Typical use |
| --- | --- | --- | --- |
| 24K | 999 | 99.9% | Bullion, investment bars and coins |
| 22K | 916 | 91.7% | High-purity jewellery (South Asia, Gulf) |
| 21K | 875 | 87.5% | Jewellery common in the Middle East |
| 18K | 750 | 75.0% | Fine jewellery, durable and bright |
| 14K | 585 | 58.3% | Everyday jewellery (Europe, US) |
| 10K | 417 | 41.7% | Budget jewellery (US minimum karat) |


## Worked example

- **Your inputs:** A 15 g 18-karat bracelet, gold at $3,900 per troy ounce, a scrap buyer offering 85% of melt.
- **Results:** Pure gold = 15 g × 18⁄24 = 11.25 g = 0.3617 troy oz. Melt value = 0.3617 × $3,900 ≈ $1,410. At 85%, the buyer would pay about $1,199.

## Frequently asked questions

### How do I calculate the value of my gold?

Multiply the weight of your gold by its purity to get the pure-gold content, then multiply by the current gold price. Purity is the karat divided by 24 (18K = 0.75), and gold is normally priced per troy ounce (31.1034768 grams). So 20 g of 18K gold is 15 g of pure gold — about 0.482 troy ounce — which at $3,900 per ounce is roughly $1,880. This tool does all three steps, in grams, troy ounces, or tola, and in any currency.

### What is the difference between 22K and 916 gold?

They describe the same purity in different units. Karat is parts of gold out of 24, so 22K is 22⁄24 = 91.67% gold. Millesimal fineness is parts per thousand, so that same gold is stamped 916 (the hallmark convention rounds 916.7 down to 916). Likewise 18K = 750 = 75%, and 14K = 585 = 58.3%. The calculator shows all three so a stamp and a karat always line up.

### How many grams are in a tola of gold?

One standard tola is 11.6638038 grams — exactly three-eighths of a troy ounce — the value fixed in British India in 1833 and still used across India, Pakistan, and Bangladesh, where ten-tola bars are common. Some bazaars quote a rounded 11.66 g. Enter your weight in tola directly and the calculator converts it, or price the gold per tola if that is how your local rate is quoted.

### Does the value include making charges or what a shop will pay?

No. The result is the intrinsic melt value — the worth of the pure gold alone. Jewellery also carries a making (labour) charge when you buy, and a dealer buying it back pays a margin below melt, so a shop offer is usually lower than the melt figure and a retail price higher. Use the optional buyer-offer percentage to estimate a realistic payout, and treat collector or antique pieces separately, since their value can exceed the metal.

### Where does the live gold price come from?

The "Get live price" button pulls the current spot price from a public market feed and converts it to your currency; a backup source keeps it working if the first is unavailable, and the result is cached briefly so it stays fast. Gold moves continuously, so the figure is a recent quote, not a locked rate — you can always type a price yourself, and the calculation is identical either way.
