Worked examples in three markets

🇺🇸

USA — per ounce

The simplest case: the spot price is the US price. One troy ounce of 24K gold is $3,887.60, one gram is $124.99. No currency conversion needed.

🇵🇰

Pakistan — per tola

Spot × USD/PKR gives Rs 35,477.28 per gram; × 11.6638 g gives Rs 413,800.03 per tola (24K). Pakistan quotes per tola first.

🇮🇳

India — per 10 grams

India uses the IBJA landed-cost benchmark, not the pure spot conversion: ₹ 135,809.00 per 10g (24K, IBJA 13 Nov 2026), or ₹ 13,580.90 per gram.

Why local prices differ from the spot conversion

If you convert the spot price into rupees or dirhams and compare it with the shop price, the shop price is almost always higher. The gap has four ingredients. First, the exchange rate: the conversion uses the interbank rate, but bullion dealers buy dollars at the open-market rate, which can differ. Second, import duty: many countries tax gold at the border, and India is the biggest example. Third, sales tax or VAT — 3% GST in India, 5% VAT in the UAE, 20% VAT on jewellery (though not on investment gold) in the UK. Fourth, the local premium and making charges: the dealer’s margin, the refinery’s cut, and the craftsmanship on a finished piece. Add them up and the shelf price can sit anywhere from under 1% above spot (a large bar in Singapore) to 20% or more (a small piece of intricate jewellery in a high-tax market).

That is also why this site does not publish one converted number per country and call it done. Pakistan is quoted per tola from the sarafa market’s convention, India from the IBJA benchmark per 10 grams, Thailand for 96.5% gold by the baht weight — each market in its own terms, with the method shown. The numbers above are today’s sheet values; the live spot behind them is on the gold spot price page, and every country’s full table is in gold price by country.

Frequently Asked Questions

What is the formula for the gold price?

Local price = (spot price per troy ounce ÷ 31.1034768) × purity factor × exchange rate × weight in grams, plus local duty, tax and premium. For 24K gold the purity factor is 1; for 22K it is 0.9167, for 21K 0.875 and for 18K 0.75.

Why is the local gold price different from the spot price?

Three reasons: the exchange rate converts dollars to local currency; local benchmarks like India's IBJA add import duty, GST and premiums; and retail prices add making charges and dealer margins on top of the wholesale figure.

How many grams are in a tola, an ounce and 10 grams?

1 tola = 11.6638038 grams; 1 troy ounce = 31.1034768 grams; 10 grams is 10 grams. A troy ounce is heavier than an ordinary (avoirdupois) ounce of 28.3495 grams — the two are often confused.

How is the 22K gold price calculated from 24K?

Multiply the 24K price by 22/24 (0.9167). 22K gold is 91.67% pure, so it holds 91.67% as much gold per gram and costs 91.67% of the 24K price for the same weight.
