Final Price: $928.31What Is a Gold Price Calculator?
A gold price calculator converts the weight and purity of any gold item into its current market value using the live spot price. Whether you hold gold coins, bars, jewellery, or raw scrap, this tool instantly tells you how much the gold content is worth — and what the all-in retail price would be including dealer premiums, making charges, and local taxes.
Enter your gold's weight (grams, troy ounces, kilograms, tola, tael, or grains), select the karat (24K, 22K, 18K, 14K, or custom purity %), enter the current spot price, and optionally add dealer spread and making charges. You'll see the pure gold content, melt value, and the final all-in price — with a visual breakdown bar showing exactly where each cost component comes from.
How to Use This Calculator
Enter the gold weight
Type in the weight of your gold item and select the unit: grams (most common), troy ounces (global standard), kilograms, tola (popular in South Asia — 1 tola = 11.66 g), Hong Kong tael (37.43 g), or grains. The calculator automatically converts to grams and troy ounces internally.
Select the karat
Choose the purity of your gold. 24K (99.99%) is investment-grade bullion. 22K (91.67%) is common in Indian jewellery. 18K (75%) is popular in European jewellery. 14K (58.33%) and 10K (41.67%) are common in US jewellery. Use 'Custom' to enter any specific purity percentage.
Enter the spot price
Enter today's gold spot price — you can input per troy ounce or per gram, and the calculator converts automatically. Use the quick presets for common reference prices, or look up the live price on sites like Kitco, Bullion Vault, or LBMA. The spot price changes continuously during market hours.
Add optional charges (for retail price)
Expand 'Advanced options' to add dealer spread (typical for coins/bars), making charges % and fixed amount (for jewellery), and local GST/VAT/sales tax. This gives you the realistic retail price, not just the melt value of the gold.
The Gold Valuation Formula
Step 1 — Find Pure Gold Content
PureGold (troy oz) = Weight (g) × Purity% / 31.1035
31.1035 g = 1 troy oz
Purity%: 24K→99.99%, 22K→91.67%, 18K→75%First convert the total weight to grams, then multiply by the purity fraction to get the pure gold content. A 10g 22K item has 9.167g of pure gold = 0.2948 troy oz.
Step 2 — Calculate Melt Value
MeltValue = PureGoldTroyOz × SpotPrice
SpotPrice = current gold price per troy oz
This is the intrinsic value of the metalMultiply pure gold in troy ounces by the spot price per troy oz. At $3,150/oz and 0.2948 oz pure gold: melt value = $928.62. This is what a refiner would pay for the metal.
Step 3 — Add Dealer Premium
AfterSpread = MeltValue × (1 + Spread%)
Spread: coins/bars 2–8%, jewellery 10–30%
Represents the dealer's profit marginDealers charge a premium above spot to profit from the transaction. A 5% spread on a $928 melt value adds $46.43. On resale, they pay below spot — so the effective spread is doubled.
Step 4 — Add Making Charges & Tax
Final = (AfterSpread + Making) × (1 + Tax%)
Making = labour/fabrication for jewellery
Tax = GST, VAT, or local sales taxFor jewellery, making charges (8–25%) cover craftsmanship. Fixed charges apply for clasp fittings, etc. Finally, local taxes like India's 3% GST or EU VAT are applied on the full subtotal.
Worked Example — 22K Gold Necklace (India)
A 22K gold necklace weighing 15 grams. Spot price $3,150/troy oz. Jeweller charges 12% making charge and 3% GST (India).
| Step | Calculation | Result |
|---|---|---|
| Weight in grams | 15 g given | 15.0000 g |
| Weight in troy oz | 15 ÷ 31.1035 | 0.4823 oz |
| 22K purity | 22 ÷ 24 = 91.67% | 91.67% |
| Pure gold (troy oz) | 0.4823 × 0.9167 | 0.4421 oz |
| Spot price / gram | $3,150 ÷ 31.1035 | $101.27/g |
| Melt value | 0.4421 × $3,150 | $1,392.62 |
| Making charge (12%) | $1,392.62 × 0.12 | +$167.11 |
| Subtotal | $1,392.62 + $167.11 | $1,559.73 |
| GST (3%) | $1,559.73 × 0.03 | +$46.79 |
| Final retail price | $1,559.73 + $46.79 | $1,606.52 |
Key takeaway: The melt value of the metal is $1,392.62 — but after making charges and GST, you pay $1,606.52. The extra $213.90 (15.4% premium) is non-recoverable when you sell jewellery back — you would typically only get the melt value back. For investment purposes, bullion bars and coins (with lower premiums) are more efficient.
