How the gold price calculator works

The calculator uses the live 24K gold spot price per gram as its base. Your entered weight is first converted to grams (1 troy ounce = 31.1034768 grams, 1 tola = 11.6638038 grams). The value is then adjusted for purity using the karat you select: the purity multiplier is simply the karat divided by 24, so 22K gold uses a multiplier of 22 ÷ 24 ≈ 0.9167.

The full formula is: value = grams × price per gram × (karat ÷ 24). Optional premium and discount percentages are applied on top of this spot value to model making charges or buyback spreads.

How to calculate gold value by gram

To value gold by the gram, divide the spot price per troy ounce by 31.1034768 to get the 24K price per gram. Then multiply by your weight in grams and by the purity of your gold. For example, if 24K gold trades at $2,600 per ounce, one gram of pure gold is worth about $83.59, and one gram of 22K (916) gold is worth about $76.62.

Difference between 24K, 22K, 21K, 18K and 14K gold

Karat measures gold purity on a scale of 24. Higher karat means more gold content and a higher value per gram, but softer metal:

  • 24K (999) — 99.9% pure gold. Used for bullion bars and investment coins.
  • 22K (916) — 91.6% pure. The standard for traditional jewellery in India, the Middle East, and Southeast Asia.
  • 21K (875) — 87.5% pure. Popular in the Middle East and parts of Europe.
  • 18K (750) — 75% pure. Common in fine jewellery and watches; more durable than higher karats.
  • 14K (585) — 58.5% pure. Widely used in the US and Europe for everyday jewellery.

What is 916 gold?

916 gold is another name for 22 karat gold. The number refers to its fineness: 916 parts of pure gold per 1,000 parts of metal, or 91.6% purity. It is the most common hallmark for gold jewellery in many markets because the small amount of alloyed metal makes it hard enough for daily wear while retaining most of the gold value.

What is 999 gold?

999 gold is 24 karat gold with a fineness of 999, meaning 99.9% pure gold. It is the standard purity for investment-grade gold bars and coins. Some refiners produce 999.9 ("four nines") gold, which is even purer. Because it is soft, 999 gold is rarely used for jewellery that will be worn daily.

Why jewellery prices may differ from spot gold price

The spot price reflects raw gold traded on global markets. Jewellery adds making charges, design and brand premiums, retail margins, and taxes on top of the metal value — often 5–25% or more. When selling, dealers usually pay below spot to cover refining and margin. Use the premium and discount fields in the calculator above to model these real-world adjustments.

Frequently Asked Questions

How do I calculate the value of gold?

Multiply the weight of your gold in grams by the live gold price per gram, then multiply by the purity (karat divided by 24). For example, 10 grams of 22K gold is worth 10 × price per gram × (22 ÷ 24). This calculator does all of that automatically using the latest spot price.

What is the difference between 24K and 22K gold?

24K gold is pure gold (99.9% fine), while 22K gold contains 22 parts gold and 2 parts other metals, making it about 91.6% pure. 22K gold is harder and more durable, which is why it is commonly used for jewellery, but it is worth roughly 8.3% less per gram than 24K gold.

What does 916 gold mean?

916 gold refers to 22 karat gold, which is 91.6% pure gold. The number 916 is the fineness marking, meaning 916 parts of gold per 1000 parts of metal. It is a common hallmark on gold jewellery in many countries.

What does 999 gold mean?

999 gold refers to 24 karat gold that is 99.9% pure, the highest purity commonly available. Investment gold bars and bullion coins are usually 999 or 999.9 fine gold.

Why is jewellery more expensive than spot gold?

Jewellery prices include making charges, design premiums, retailer margins, and taxes on top of the metal value. The spot price only reflects the raw metal traded on global markets, so finished jewellery typically costs more per gram than the spot price of its gold content.

Does this calculator include making charges?

By default the calculator shows the pure metal value based on the spot price. You can add an optional premium or making fee percentage to estimate a retail price, or a discount percentage to estimate a buyback or scrap price.

Can I calculate gold price in different currencies?

Yes. The calculator supports over 20 currencies including USD, EUR, GBP, INR, AED, SAR, MYR, and SGD. Prices are converted from the live USD spot price using current exchange rates.

Is the calculator price the same as dealer buyback price?

No. Dealers typically buy gold below the spot price to cover refining costs and margin. Use the discount field to model a buyback spread, and always compare quotes from multiple dealers.
