how to calculate 18k gold rate from 22k?
Hi,
You can easily calculate the 18K gold rate from the 22K rate by looking for purity. 22K gold is 91.6% pure, while 18K gold is 75% pure.
The formula is 18K gold rate = (18 ÷ 22) × 22K gold rate
You can calculate the 20k gold rate by first checking the 24K gold rate in your city.
For example, if today’s 22K gold rate is ₹5,500 per gram:
18K gold rate = (18 ÷ 22) × 5,500 = ₹4,500 per gram (approx).
This gives you the base rate for 18K gold while making charges and GST will be added by jewellers on top of this price.
