Gold price

Fetching the live spot rate…

Enter a 24K price per gram (or fetch live) and a weight to see the value.

🪙 We fetch only the public gold spot price and exchange rate; your weights and inputs stay in your browser. Live FX updates roughly daily and retail jewellery prices include premiums — treat this as a valuation guide, not a trading quote.

How It Works

Calculates the value of gold from its weight, purity (karat) and currency, with per-gram, per-tola and per-baht breakdowns for 24K/22K/21K/18K/14K. The math is local; the live spot price and exchange rate are one optional, read-only fetch, with manual entry for full offline use.

  1. 1
    Set the 24K price
    Enter today’s 24K price per gram, or tap “Use live rate” to fetch the public gold spot price and convert it to your currency. The value is editable — local retail rates carry premiums.
  2. 2
    Enter weight, unit and karat
    Weigh in grams, tola (11.664 g), baht (15.244 g) or troy ounce. Value = weight × (karat ÷ 24) × price-per-gram. Optionally add making charges and India GST (3% gold + 5% making).
  3. 3
    See the full breakdown
    Total value plus metal value, making, GST, the chosen karat’s per-gram/tola/baht price, and a price table across all purities.
