What Is a Gold Price Calculator?
A gold price calculator converts three facts, weight, purity and the day's rate, into a rupee value. Doing it by hand means turning a karat into a percentage, subtracting stones, applying the rate and then layering on making charges and GST. One slip and the answer is off by thousands. This calculator handles each step and shows the working, so you can check a jeweller's bill or an offer before you agree to it.
It covers both sides of a deal. Buy mode adds making charges, wastage and GST to the gold value. Sell mode subtracts a buyer deduction to estimate the cash you would really receive.
How to Use the Gold Price Calculator
Step 1: Enter weight and subtract stones
Type the gross weight and choose a unit: grams, kilograms, tola, pavan or troy ounce. If the piece has diamonds, pearls or beads, enter their weight under stone weight. Only the net gold weight is valued.
Step 2: Pick the karat
Check the hallmark stamp. BIS hallmarks show fineness as 916 for 22K, 750 for 18K and 585 for 14K. Use the custom option for unusual purity.
Step 3: Enter today's rate
Type the rate and say whether it is per gram or per 10 grams, and whether it applies to 24K or to your karat. Indian jewellers usually quote a 24K and a 22K rate. Choose "My selected karat" if you are using the 22K rate.
Step 4: Read the breakdown
The result updates as you type. Use Add to list to total several pieces, then save a PDF report for your records.
The Gold Value Formula
- Net weight = gross weight − stone weight
- Pure gold = net weight × (karat ÷ 24)
- Gold value = pure gold × 24K price per gram
- Buy total = (gold value + making + wastage) × (1 + GST%)
- Sell payout = gold value × (1 − deduction%)
Gold Purity Explained: 24K, 22K, 18K and 14K
Pure gold is soft, so jewellers alloy it with copper, silver or zinc. The karat tells you how many of 24 parts are gold. Lower karat means less gold per gram, so a lower value.
| Karat | Gold content | Hallmark | Typical use |
|---|---|---|---|
| 24K | 99.9% | 999 | Coins, bars, investment |
| 22K | 91.6% | 916 | Traditional jewellery |
| 18K | 75.0% | 750 | Diamond and modern jewellery |
| 14K | 58.5% | 585 | Light everyday wear |
Making Charges, Wastage and GST
Making charges
Making charges pay for craftsmanship. They are charged as a percentage of gold value or a flat amount per gram. Intricate pieces cost more, and these charges are negotiable.
Wastage
Some jewellers add wastage for metal lost while crafting. Always ask whether it is included in the making charge so you do not pay twice.
GST
Gold jewellery in India attracts 3% GST on the total of gold value and making. Check the current rate before you buy, since tax rules change.
Buying vs Selling: Why the Numbers Differ
The gold value is a market figure. When you buy, you pay that plus making, wastage and tax. When you sell, the buyer deducts for melting, testing and margin, and making charges are almost never refunded. A piece bought for ₹1,03,800 may fetch close to ₹88,000 on resale. Use Sell mode to set expectations, and compare at least two buyers.
Factors That Move Gold Prices in India
International rates
Domestic prices follow global spot gold, shaped by interest rates, central bank buying and investor demand.
Rupee–dollar exchange rate
Gold is priced in dollars, so a weaker rupee raises the price in India even when global gold is flat.
Import duty and local demand
India imports most of its gold, so customs duty matters. Festival and wedding seasons also lift demand.
Tips for an Accurate Valuation
- Weigh on a calibrated digital scale and subtract stones.
- Read the karat from the hallmark, not only the bill.
- Use the same day's rate; it changes daily.
- Ask for making charges and wastage in writing.
- Get more than one quote before selling.

Frequently Asked Questions
How do I calculate the price of my gold?
Multiply the net weight in grams by karat ÷ 24, then by the 24K price per gram. The calculator does this automatically and can add making charges, wastage and GST.
What is the difference between 22K and 24K gold?
24K gold is about 99.9% pure. 22K gold is about 91.6% pure and alloyed with copper or silver for strength, which is why it is used for jewellery.
Should I enter the 24K rate or the 22K rate?
Either. Use the "Rate applies to" option: choose 24K if you have the 24K rate, or "My selected karat" if your jeweller quoted the 22K or 18K rate directly.
Why do jewellers offer less than the calculated value?
Buyers deduct for melting loss, hallmark testing and margin, and making charges are rarely refunded. Use Sell mode with a deduction percentage to see a realistic payout.
Is stone weight included in gold weight?
No. Stones, pearls and beads should be subtracted. Enter the stone weight and the calculator uses only the net gold weight.
Is the gold price calculator accurate?
The maths is exact for the numbers you enter. For real-world accuracy, enter today's live rate and the correct making charge and GST percentages.
