How the Gold Rate Price is Calculated
Calculating the value of gold involves three primary factors: the weight of the item, the purity of the gold (measured in Karats), and the current live market price of gold. Since pure gold (24K) is often too soft for jewelry, it is mixed with alloys, which reduces its market value per gram.
The Mathematics of Gold Pricing
The formula used by jewelers and gold buyers is as follows:
Total Value = [(Weight × (Karat / 24)) × Price Per Gram] + Making Charges
Step 1: Determine Purity Percentage. Divide the Karat by 24. For example, 18K gold is 18/24, which equals 0.75 or 75% purity.
Step 2: Calculate Fine Gold Weight. Multiply the total weight by the purity percentage. If you have 10 grams of 18K gold, you have 7.5 grams of pure gold.
Step 3: Market Valuation. Multiply the fine gold weight by the current 24K gold price per gram.
Understanding Karats and Purity
| Karat | Purity Percentage | Common Use |
|---|---|---|
| 24K | 99.9% | Investment bars/coins |
| 22K | 91.6% | Traditional jewelry |
| 18K | 75.0% | Fine jewelry, watches |
| 14K | 58.3% | Commercial jewelry |
Realistic Example Calculation
Suppose you have a 22K gold chain weighing 15 grams. If the current market price for 24K gold is $65.00 per gram and the jeweler charges a 5% making fee:
- Purity: 22 / 24 = 0.9166
- Fine Gold: 15g × 0.9166 = 13.75g
- Base Value: 13.75g × $65.00 = $893.75
- Making Charges: $893.75 × 0.05 = $44.69
- Total Price: $893.75 + $44.69 = $938.44
Factors Influencing Gold Prices
The price of gold is highly volatile and fluctuates throughout the trading day based on global economic conditions. Major factors include:
- Central Bank Reserves: When central banks increase their gold reserves, prices typically rise.
- Inflation: Gold is often used as a hedge against inflation, increasing in demand when currency value drops.
- Interest Rates: Higher interest rates can lead to lower gold prices as investors move toward yield-bearing assets.
- Making Charges: When buying jewelry, the "making charge" or "wastage" covers the labor and manufacturing cost, which can range from 3% to 25% of the total value.
