How we calculate the gold rate
Gold rates are financial information people act on, so we show exactly where ours come from. In short: our rates are indicative estimates derived from the international gold price. They are not quotes from a particular jeweller, and they are not the official IBJA benchmark.
Data sources
- Primary: gold-api.com, a free feed of the international gold spot price (XAU) converted to Indian rupees. We fetch it every 15 minutes.
- Fallback and history: the open-source exchange-api daily dataset, which gives one gold-to-rupee reference value per day. We use it if the primary feed fails, and for rates before our own recording began.
The formula
24K rate per gram = (spot price in ₹ per troy ounce ÷ 31.1034768) × (1 + customs duty)
22K rate = 24K × 0.9167
18K rate = 24K × 0.75
Customs duty is the effective duty on imported gold: basic customs duty plus the Agriculture Infrastructure and Development Cess. It is currently 15%, in force since 13 May 2026. Each day in our history uses the duty in force on that date:
| From | Effective duty |
|---|---|
| 1 Jul 2022 | 15% |
| 24 Jul 2024 | 6% |
| 13 May 2026 | 15% |
All rates are rounded to the nearest rupee per gram and exclude 3% GST, making charges and hallmarking fees.
Updates and timestamps
- We record a new rate every 15 minutes. The time shown on each page is when we recorded the rate shown.
- “Yesterday” and daily history use the last rate we recorded on each calendar day (Indian Standard Time).
- International markets close at the weekend, so rates usually stay flat from Friday night to Monday morning.
When data is missing
If no new rate has arrived for 6 hours, the page says so and shows the last verified figures with their time. If we have no verified figure at all, we show no numbers. We never fill gaps with guesses.
Limits you should know about
- Jewellers in Bangalore set their own board rates. Theirs may be slightly higher or lower than ours, and they change their boards at different times of day.
- Our figure doesn’t include local premiums or discounts, bank charges on imports, or the jeweller’s margin.
- Buy-back rates for old gold are usually lower than selling rates.
- Rates before our own recording began are once-a-day reference values, so they don’t show intraday moves.
