Gold is not just jewellery in India — it is savings, security, tradition, and investment all in one. Whether you are buying a gold ring at a local jeweller, selling old gold bangles, or investing in gold coins — knowing exactly how to calculate the price per gram is the most important skill before any gold transaction.
This guide teaches you the exact formula to calculate gold price for any weight, explains the difference between 22K, 24K, and 18K gold, and shows you how to verify you are being charged correctly at any jewellery shop — today, tomorrow, or any day in the future.
Note on gold prices: Gold rates in India change every single day based on global markets. This guide uses example prices to teach you the formula. Always check today’s current gold rate from your jeweller, or search “gold rate today in [your city]” on Google before any purchase or sale.
How to Check Today’s Gold Price
Before using any formula, you need today’s actual rate. Here is how to find it in under 30 seconds:
- Google: Search “gold rate today Delhi” or your city name
- RBI / MCX: Check Multi Commodity Exchange (mcxindia.com)
- Your jeweller: Ask specifically for “aaj ka 22 karat rate per gram”
- Trusted sites: GoodReturns, PolicyBazaar, or Muthoot Finance show live rates
Gold prices are revised daily at market opening. The rate you see today may be different tomorrow.
Understanding Gold Karat — Before You Calculate Anything
This is the most important thing to understand before buying gold in India.
24 Karat Gold (999 Gold)
- Purity: 99.9% pure gold — the purest form available
- Best for: Investment — coins, bars, digital gold
- Not recommended for: Jewellery — too soft, scratches and bends easily
- Hallmark stamp: 999
22 Karat Gold (916 Gold)
- Purity: 91.6% gold + 8.4% other metals for durability
- Best for: All jewellery — rings, bangles, necklaces, chains
- Most commonly bought gold in India
- Hallmark stamp: 916
18 Karat Gold (750 Gold)
- Purity: 75% gold + 25% other metals
- Best for: Diamond jewellery settings, modern lightweight designs
- Cheaper per gram than 22K and 24K
- Hallmark stamp: 750
Key rule: Higher karat = higher purity = higher price per gram. 24K is always more expensive than 22K, which is always more expensive than 18K.
The Formula — How to Calculate Gold Price for Any Weight
To find the price for a specific weight: Price = Weight in grams × Gold rate per gram
To find how many grams you can buy with your budget: Weight = Your budget ÷ Gold rate per gram
This is the same Rule of Three formula used for everyday market calculations — just like calculating price per gram for groceries.
Examples — Let Us Say Today’s 22K Gold Rate Is ₹X Per Gram
Since gold prices change daily, let us use a simple example to understand the formula. Wherever you see ₹X, replace it with today’s actual rate from Google or your jeweller.
Let us say today’s 22K gold rate is ₹9,000 per gram (this is an example only — check today’s actual rate):
| Weight | Calculation | Gold Value |
|---|---|---|
| 1 gram | 1 × 9,000 | ₹9,000 |
| 2 grams | 2 × 9,000 | ₹18,000 |
| 5 grams | 5 × 9,000 | ₹45,000 |
| 8 grams | 8 × 9,000 | ₹72,000 |
| 10 grams | 10 × 9,000 | ₹90,000 |
| 15 grams | 15 × 9,000 | ₹1,35,000 |
| 20 grams | 20 × 9,000 | ₹1,80,000 |
Now do the same with today’s actual rate: If today’s 22K rate is ₹14,000 per gram (check Google for real rate):
- 5 grams = 5 × 14,000 = ₹70,000
- 10 grams = 10 × 14,000 = ₹1,40,000
The formula never changes — only the rate changes daily.
The Relationship Between 24K, 22K and 18K Prices
Once you know one karat’s rate, you can estimate the others:
22K rate = 24K rate × 0.916 18K rate = 24K rate × 0.75
Example — If 24K gold is ₹10,000 per gram today:
- 22K = 10,000 × 0.916 = ₹9,160 per gram
- 18K = 10,000 × 0.75 = ₹7,500 per gram
This formula works regardless of what today’s actual gold price is.
The Real Cost of Gold Jewellery — What You Actually Pay
Many buyers are shocked when the final bill is much higher than the gold value calculation. This is because jewellery has additional charges on top of the gold value:
Making Charges
Making charges are the cost of crafting the design. These vary:
- Simple plain designs: 5-8% of gold value
- Medium designs: 10-15% of gold value
- Intricate designs: 20-25% of gold value
- Branded jewellers (Tanishq, Kalyan etc.): Fixed charge per gram
GST
- 3% GST on the gold value
- 5% GST on making charges
Full Example Calculation
Let us say today’s 22K rate is ₹9,000/gram. You buy a 10 gram necklace with 12% making charges:
| Component | Calculation | Amount |
|---|---|---|
| Gold value | 10 × ₹9,000 | ₹90,000 |
| Making charges (12%) | 12% of ₹90,000 | ₹10,800 |
| Subtotal | ₹1,00,800 | |
| GST on gold (3%) | 3% of ₹90,000 | ₹2,700 |
| GST on making (5%) | 5% of ₹10,800 | ₹540 |
| Total you pay | ₹1,04,040 |
This is why the final bill is always significantly higher than just (weight × rate).
How to Calculate the Value of Your Old Gold
If you own gold jewellery and want to know its current value before selling:
Current value = Weight × Current rate per gram × Purity percentage
Example — 22K gold bangle weighing 15 grams
If today’s 22K rate is ₹9,000/gram: Value = 15 × 9,000 = ₹1,35,000
When selling, jewellers typically pay 95-97% of this value. So you would receive approximately ₹1,27,500 to ₹1,30,950.
Always get the purity tested before selling. Old gold from decades ago may not be exactly 22K.
How to Use RateCalc for Gold Calculations
RateCalc.in makes gold price calculations instant — the same way it helps calculate milk price per litre, petrol price per litre, or any proportional calculation.
Step 1: Check today’s gold rate on Google — for example ₹9,000 per gram for 22K.
Step 2: Open RateCalc. Enter:
- Known Price: ₹9,000
- Known Quantity: 1g
- Select unit: g
Step 3:
- To find price for 8 grams → enter 8g in “Find Price” mode → ₹72,000
- To find grams for ₹50,000 budget → enter ₹50,000 in “Find Quantity” mode → 5.55 grams
Tip: Save “Gold 22K” with today’s rate in My Shop Items. When the rate changes tomorrow, edit and update in 10 seconds.
10 Things to Check Before Buying Gold Jewellery
1. Always check the BIS Hallmark Look for the BIS logo and karat stamp (916 for 22K, 999 for 24K) on every piece. This confirms certified purity.
2. Weigh the gold yourself Ask to see the weight on the digital scale. Never accept verbal weight confirmation.
3. Calculate the gold value before agreeing Use the formula yourself: Weight × Today’s rate = Gold value. Do this before accepting the jeweller’s total.
4. Understand making charges Making charges are negotiable at independent jewellers. Always ask for a reduction on plain designs.
5. Confirm stones are not included in gold weight Diamonds, rubies, and other stones should not be charged at the gold rate. They should be weighed and priced separately.
6. Ask for a detailed itemised bill The bill must show: gold weight, gold rate per gram, gold value, making charges, GST breakdown, and total. Never accept a lump sum bill.
7. Compare rates before buying Gold rates are the same from reputable jewellers on any given day. If one jeweller’s rate is very different, ask why.
8. Avoid buying on impulse on auspicious days Dhanteras and Akshaya Tritiya see huge demand. Prices may be slightly higher and shops are crowded. Consider buying 2-3 days before.
9. Consider digital gold for investment If buying purely for investment, digital gold (Paytm Gold, MMTC-PAMP) and Gold ETFs avoid making charges entirely.
10. Keep all purchase receipts When selling later, a receipt showing your purchase rate and weight helps you calculate your actual profit or loss.
Selling Old Gold — What You Should Expect to Receive
When selling old gold jewellery, deductions apply:
| Seller Type | Typical Deduction |

| Local unorganised jeweller | 5-8% |
| Organised jeweller (Tanishq, Malabar) | 2-5% |
| Gold loan company | Loan at 75-85% of gold value |
| Cash for gold shops | 8-15% |
Always get quotes from at least 2-3 buyers before selling.
