In India, gold is more than just a metal; it is an investment and a cultural cornerstone. The price of 1 gram of gold is the most sought-after figure for small investors and jewelry buyers. While market tickers usually display the 10-gram price (1 Tola), calculating the per-gram rate involves several variables including purity, making charges, and taxes.
How Gold Price is Calculated
The final price of gold jewelry in India is determined by the following formula:
Final Price = (Price of Gold × Weight) + Making Charges + GST (3% on total)
24K vs 22K Gold
24 Karat Gold: This is 99.9% pure gold. It is highly malleable and not suitable for intricate jewelry. It is mostly used for coins and bars.
22 Karat Gold: This contains 91.67% gold mixed with metals like copper or zinc to add strength. This is the standard for most Indian jewelry (often marked as 916 KDM).
18 Karat Gold: Contains 75% gold, used primarily for diamond-studded jewelry to ensure the stones are held securely.
Example Calculation
If the market rate for 10 grams of 24K gold is ₹60,000, and you want to buy 1 gram of 22K jewelry:
1 Gram 24K Price: ₹60,000 / 10 = ₹6,000.
1 Gram 22K Price: ₹6,000 × 0.9167 = ₹5,500.
With Making Charges: If making charges are ₹500, the subtotal is ₹6,000.
With 3% GST: ₹6,000 + 3% (₹180) = ₹6,180 Total.
Important Factors to Watch
Gold rates in India fluctuate daily based on international market trends, the USD to INR exchange rate, and local demand during festive seasons like Diwali and Dhanteras. Always ensure you check the Hallmark (BIS) on jewelry to verify the purity you are paying for.
