A Gold Calculator is an online or offline tool that helps you calculate the value of gold based on three main factors: weight, purity, and current gold rate. It removes confusion and gives you a clear idea of how much your gold is worth. Let us understand this in simple words. Suppose you have a gold chain that weighs 20 grams. You also know that it is 22 karat gold. The gold rate today is ₹6,000 per gram. Instead of doing complex math, you can use a Gold Calculator.
