How this calculator works
The calculator starts from the live 24K gold price per troy ounce, converted to INR at the current exchange rate. Your weight is converted to grams (1 troy ounce = 31.1034768 g, 1 tola = 11.6638038 g), and the value is adjusted for purity — the multiplier is simply the karat divided by 24, so 22K/916 gold uses 22 ÷ 24 ≈ 0.9167. The formula: value = grams × pure gram price × purity, plus any premium and minus any discount you enter.
In India, 22K (916) gold is the standard for wedding and traditional jewellery, certified by the BIS hallmark with the 916 stamp. Jewellers publish daily 22K and 24K rates and add making charges — typically a percentage of the metal value — on top of the board price.
