How Much is Your Gold Worth? - Gold Value by Weight
Gold value at current market rate. Use the calculator above for any weight.
How to Calculate Gold Value - 3 Simple Steps
Step 1: Weigh Your Gold
Use a digital kitchen scale or jewelers scale. Weigh in grams (most accurate) or ounces. Remove any non-gold parts like stones or clasps before weighing for a pure metal value.
Step 2: Identify the Purity
Check for karat stamps on your gold: 10K, 14K, 18K, 22K, or 24K. Common stamps include:
- 14K or 585 = 58.5% pure gold
- 18K or 750 = 75% pure gold
- 10K or 417 = 41.7% pure gold
Step 3: Use the Calculator
Enter the weight and select the purity. The calculator instantly shows your gold's melt value—the amount you'd get at current gold price per gram for that purity. For scrap/selling estimates, use the scrap gold calculator below.

Why does a /gold-price date page show a different number than the homepage calculator?
The homepage uses a current live spot-style snapshot. Daily URLs under /gold-price read one archived UTC-day summary from our daily OHLC table—different upstream feeds and session cut-offs can disagree slightly. Full rules: Gold price methodology (/gold-price-methodology).
