Pure gold in 22K, 18K or 14K jewellery, and the rate of each karat from 24K
Estimates only, not financial advice. What you type stays on your device. Checked against sources on 23 Oct 2026, except the tola of 180 grains (Standards of Weights Act, 1939), not read that day; the Hindi page of the BIS FAQ, read 23 Oct 2026, shows Rs 35 a gold article, not the English page's Rs 45.Hallmarked 22K gold is 91.6% pure, so 10 grams of 22K jewellery holds 9.16 grams of pure gold, which equals 9.17 grams of 24K 999 gold. Enter any karat and weight to see the pure gold inside, the equal weight in other karats, and the 22K and 18K rates worked out from the 24K rate per 10 grams you enter.
Rates and rules read from the sources listed on this page (the earliest on 23 Oct 2026); they may have changed since. Not covered by that date: the tola of 180 grains (Standards of Weights Act, 1939), not read that day; the Hindi page of the BIS FAQ, read 23 Oct 2026, shows Rs 35 a gold article, not the English page's Rs 45.

The calculator does three jobs: it prices a piece of gold jewellery the way a jeweller bills it, converts between karats, and converts tola, masha and ratti to grams.
How a jewellery bill is built. Gold rates are quoted for 24K (999) gold per 10 grams. A lower karat is charged at its purity share of that rate: 91.6% for 22K and 75% for 18K, the fineness the BIS hallmark stamps under IS 1417. The gold value is that rate per gram times the net weight. The making charge is added, either as a percentage of the gold value or as rupees per gram, then the hallmark (HUID) charge, which BIS collects from jewellers at ₹45 per article. GST is 3% on the total, making charges included, under Notification 9/2025-Integrated Tax (Rate), which kept gold at 3% when the GST rates changed on 22 September 2025.
Karats. A karat is a part in 24, so 22K works out to 91.67% pure, but the hallmark standard fixes 22K at 91.6%, and that is the figure used everywhere in trade. The karat converter shows how much pure gold a piece holds and what the same gold weighs in other karats.
The rest of the article, and all 6 questions about Gold Calculator, are on the Gold Calculator page.
Price equals the gold rate per gram for the purity, times the net weight, plus the making charge and the hallmark charge, plus 3% GST on that total. For 10 g of 22K at a 24K rate of ₹1,00,000 per 10 g with 12% making, the bill comes to about ₹1,05,716.
Gold and gold jewellery carry 3% GST, and a jeweller's making charge is part of the jewellery's price, so the 3% applies to it as well. The rate did not change on 22 September 2025. Making charges alone, when you supply your own gold, are job work taxed at 5%.
Multiply the 24K rate by 0.916. At ₹1,00,000 per 10 g for 24K, 22K is priced at ₹91,600 per 10 g and 18K, at 0.75, at ₹75,000. Some jewellers publish their own 22K board rate, which can differ slightly from this share.
No. Gold rates change every day and differ slightly between cities and shops, so the calculator uses the 24K rate you enter. The ₹1,00,000 figure is only an example. Use the rate on your jeweller's board or the day's published bullion rate.
Rates and rules change; check the source before you rely on a figure.
