Indian households hold an estimated 25,000 tonnes of gold, roughly 11% of the world’s total above-ground stock. Most of it sits in lockers and jewellery boxes. The question every family asks before a wedding, a loan, or a sale: what is this gold actually worth today?
Enter the weight, select your purity, update the rate from MCX, and you have the number in two seconds.
How gold value is calculated
The formula is three steps.
First, convert your weight to grams. One tola equals 11.6638 grams. One sovereign (standard South India unit) equals 8 grams. If your gold is already in grams, nothing to convert.
Second, apply purity. 22 karat gold is 91.67% pure gold. So 10 grams of 22K jewellery contains 9.167 grams of actual gold. The rest is copper or silver alloy added for hardness. 24K is pure, 18K is 75%, 14K is 58.33%.
Third, multiply pure gold grams by the 24K rate per gram. If today’s 24K rate is ₹9,500/gram and you have 9.167 grams of pure gold, value = ₹87,086.
Value = Weight (g) × Unit factor × Purity factor × 24K rate per gram
Where to get today’s gold rate
The calculator defaults to an approximate rate. Update it with today’s actual price from one of these:
- MCX (Multi Commodity Exchange): mcxindia.com — Gold futures price in ₹/10g, divide by 10 for per-gram rate
- India Bullion and Jewellers Association (IBJA): ibjarates.com — Daily morning and evening fixing rates
- Your local jeweller: They price based on the IBJA rate plus a small spread
MCX and IBJA rates are for 24K (999 purity). The calculator handles the purity conversion automatically.
22K vs 24K: what jewellers actually buy back
Almost all Indian jewellery is 22K. When you sell gold jewellery back to a jeweller, they calculate:
Buyback value = Weight in grams × 22K rate × (reported purity / 100)
The 22K rate on any given day is approximately 24K rate × 0.9167. Jewellers often quote their own buyback rate which may be 2–5% below IBJA. The calculator shows market value; actual buyback will be slightly lower.
Hallmarking and purity: the BIS standard
Since June 2021, BIS hallmarking is mandatory for gold jewellery sold in India. The hallmark includes the BIS logo, purity in fineness (999 for 24K, 916 for 22K, 750 for 18K, 585 for 14K), and a 6-character HUID (Hallmark Unique ID).
If your gold has a BIS hallmark showing 916, it is 22K (91.6% pure). Use the 22K setting in the calculator. Old jewellery without hallmarking is trickier — a karat testing machine at any jeweller can verify purity in about 30 seconds. Never assume purity on old pieces.
Making charges are not included
The calculator shows the metal value only. When you buy jewellery, you pay:
- Gold value (metal cost at daily rate)
- Making charges: 8–25% of gold value depending on design complexity
- GST: 3% on (gold value + making charges)
When you sell, you recover only the metal value minus buyback discount. Making charges and GST are sunk costs. This is why buying plain gold coins or bars at 1–2% making charges is far more efficient than ornate jewellery at 20% making charges if your goal is investment.
Gold coins vs jewellery vs ETFs vs Sovereign Gold Bonds
| Form | Purity guaranteed | Buyback ease | Making charges | Annual returns |
|---|---|---|---|---|
| 24K coin / bar (BIS hallmark) | Yes | Good (any jeweller) | 1–3% | Market rate |
| 22K jewellery | Yes (if hallmarked) | Moderate (discount) | 8–25% | Market minus charges |
| Gold ETF | 99.5% equivalent | Excellent (sell on exchange) | 0.4–0.5% expense ratio | Market rate |
| Sovereign Gold Bond | GOI guaranteed | Locked 8 yrs (early exit on exchange) | None | Market + 2.5% p.a. interest |
For pure investment, Sovereign Gold Bonds win when available — you get gold price appreciation plus 2.5% annual interest, all tax-free at maturity if held 8 years. Gold ETFs are second best for liquidity. Physical gold makes sense for jewellery needs, not as a pure investment vehicle.
Frequently asked questions
Why does my jeweller quote a lower rate than MCX?
MCX is the futures market rate. Physical gold trades at a small premium or discount to MCX depending on import duties, local demand, and the jeweller’s own margin. IBJA rates are closer to physical transaction prices. For valuation purposes, use IBJA morning rate. For a rough estimate, MCX ÷ 10 (per gram) is close enough.
How do I calculate the value of gold coins from a bank?
Bank gold coins (SBI, Axis, HDFC, etc.) are 24K (999.9 purity) and come in standard weights of 2g, 4g, 8g, 10g, 20g, 50g. Select grams, 24K purity, enter the weight, and you have the value. Banks typically charge a 3–7% premium over MCX when selling; buyback is at spot.
What is the 80/20 rule for gold loans?
Most banks and NBFCs (Muthoot, Manappuram, IIFL Gold) lend 75–90% of the gold’s market value. If your 50 grams of 22K gold is worth ₹4.35 lakh at today’s rate, you can get a gold loan of ₹3.26–3.91 lakh. The calculator helps you estimate the gold value before approaching a lender.
Does hallmarking change the buyback value?
Yes. Hallmarked gold commands better buyback rates because purity is certified. Unverified old jewellery may get a 2–5% purity haircut from jewellers who test it and find it slightly below stated karat. Always get old jewellery hallmarked before selling if you have time.
