how to calculate 18 carat gold rate?
Gold is usually priced in 24 carat (pure gold), so to find the 18 carat rate, you just need to calculate 75% of the 24 carat price because 18k gold has 75% pure gold mixed with other metals.
For example, if today’s 24k gold price is ₹6,000 per gram, then the 18k gold price will be 6,000 × 75% = ₹4,500 per gram. On top of that, jewellers usually add making charges and taxes, which increase the final cost of the jewellery.
