How to use gold rate calculator
- Enter weight, purity and today's rate
Use the 24K (999) rate published today — the tool applies the purity conversion for 22K/18K automatically.
- Add making charges and hallmarking
Making charges are usually a % of gold value or a flat ₹/gram — use whichever your jeweller quotes.
- Calculate

Formula & methodology
Effective rate = 24K rate × purity factor (22K = 22/24 = 0.9167, 18K = 18/24 = 0.75). Gold value = weight × effective rate. Making charges = gold value × % (or weight × ₹/gram). Final price = (gold value + making charges) × 1.03 (3% GST) + hallmarking charge.
Example: 10g of 22K gold at a ₹7,500/gram 24K rate, 12% making charges, ₹45 hallmarking — effective rate ₹6,875/gram, gold value ₹68,750, making ₹8,250, GST on ₹77,000 is ₹2,310, hallmarking ₹45 → final price ≈ ₹79,355.

Frequently asked questions
Where do I find today's 24K gold rate?
Most jewellers, banks and financial news sites (e.g. MCX, India Bullion and Jewellers Association) publish a daily 24K/999 gold rate — enter that figure here.
Why is 22K gold cheaper than 24K for the same weight?
22K gold is only 91.6% pure gold by weight (the rest is alloy metal for strength) — so its effective gold content, and therefore its price, is proportionally lower than 24K.
Is GST really charged on making charges too?
Yes — under current Indian GST rules, the 3% GST applies to the combined value of gold plus making charges, not gold value alone.
Does this account for old gold exchange or discounts?
No — this calculates a fresh purchase price only. Old-gold exchange value, jeweller-specific discounts and wastage charges (if applied separately from making charges) aren't modelled here.
