Understanding Gold Valuation

Karat Purity: Indicates the percentage of pure gold in an alloy. Higher karat means more gold content and higher value.

Market vs. Selling Price: The calculator shows market value. Actual selling prices are typically 60-95% of market value depending on the buyer.

Weight Matters: Gold is sold by weight. Even small differences in weight can significantly impact the total value.
