Gold has been a timeless store of wealth and a valuable investment for centuries. Whether you’re a jeweler, investor, or simply someone wanting to sell an old gold piece, knowing its true value is crucial. The challenge? Gold value depends on more than just weight—it’s about purity, weight, and current market price.
Our Karat Gold Calculator takes out the guesswork and delivers instant, precise results. You enter the weight, karat, and current gold price per gram, and the tool calculates the pure gold value in seconds.
Karat Gold Calculator
💡 Why Use a Karat Gold Calculator?
Gold isn’t always pure—most jewelry and coins are made with varying amounts of other metals for durability and color. The karat rating tells you how pure the gold is.
For example:
- 24K = 99.9% pure gold
- 18K = 75% pure gold
- 14K = 58.3% pure gold
If you don’t adjust for purity, you risk overestimating or underestimating your gold’s value. This is where the calculator becomes essential.
🛠️ How to Use the Karat Gold Calculator
Using our tool is quick and easy. Just follow these steps:
1. Enter the Gold Weight (grams)
Weigh your gold item using a jewelry scale for accuracy. Enter the weight in grams (you can use decimals for precision).
2. Enter the Karat (1–24)
Look for a hallmark stamp on your gold (e.g., “18K” or “750”) or have it tested. Enter the correct karat rating.
3. Enter the Gold Price per Gram
Check the current gold market rate (usually in USD per gram) from a trusted source and input that value.
4. Click Calculate
Press the “Calculate” button, and the tool instantly shows the pure gold value in currency.
5. View Results
The tool displays the exact monetary value of the pure gold content in your item.
📊 Example Calculation
Imagine you have a gold chain with these specs:
- Weight: 25 grams
- Karat: 18K (75% purity)
- Current Gold Price: $60 per gram
Calculation:
Purity fraction = 18 ÷ 24 = 0.75
Pure gold weight = 25 × 0.75 = 18.75 grams
Value = 18.75 × $60 = $1,125.00
The calculator instantly gives you this figure—no manual math needed.
🔍 Understanding the Formula
The calculator uses this formula:
Pure Gold Value = Weight × (Karat / 24) × Price per Gram
Where:
- Weight = total weight of your gold item in grams
- Karat/24 = purity fraction
- Price per Gram = current market price
