Rate Methodology

GoldMap uses the India Bullion and Jewellers Association (IBJA) published benchmark rates as the reference input for its daily gold and silver surfaces. IBJA publishes opening (AM) and closing (PM) rates for gold purities including 999, 916, 750 and 585, and for Silver 999. The published gold figures are per 10 grams and silver is per 1 kilogram.

GoldMap is an independent information site. It does not claim to publish jeweller quotations or official city shop prices. The rate shown on a GoldMap page is a reference figure built from the published benchmark input and GoldMap's documented calculation rules.

1. If IBJA has published a PM/closing rate for the day, GoldMap uses the PM rate.
2. If no PM rate is published, GoldMap uses the AM/opening rate.
3. On days when IBJA does not publish rates, GoldMap does not invent a new row; the latest available published day remains the reference until a new rate is available.

Each production update records the source session used, so the displayed rate and the history row can be traced back to a specific published market input.

Gold conversions use half-up rounding. Silver is displayed to two decimal places. The same derived values feed the homepage, Pavan surfaces, calculators and history so a single published input does not turn into conflicting figures across pages.

Kochi and Kozhikode are used as the base reference. GoldMap's current city-reference adjustments are +₹2/g for Thrissur, Kollam and Kottayam, and +₹5/g for Thiruvananthapuram and Kannur. These are GoldMap reference calculations, not claims that every jeweller or local association publishes the same amount.

This distinction matters because the final shop price may differ for reasons that a benchmark table cannot capture: making charges, wastage or value addition, GST, stone weight, discounts, inventory, and the jeweller's own margin.

The displayed figure is the benchmark pure-metal reference used for GoldMap's educational tools. It is not a finished-jewellery quotation and does not include making charges, wastage/value addition, jeweller margin, stone cost or a shop-specific discount. IBJA's published rates are also stated without GST/VAT and without making charges.

For finished jewellery, use the Making Charges Calculator and then compare the result against the actual itemised bill.

GoldMap is updated on published trading days. If you spot a rate or content error, send the date, page and value through the contact page. Confirmed corrections are applied to the source data and regenerated surfaces rather than patched independently on individual pages.
