Calculation Formula & Example
📐 Calculation Formula
- Weight = Your gold weight in grams
- Price per Gram = Troy ounce price ÷ 31.1034768
- Purity Factor = Karat ÷ 24
- Payout % = Buyer's percentage (85-98%)
💡 Example Calculation
Scenario: You have 10 grams of 18K gold jewelry
Current Troy Ounce Price: $3,527.76
Buyer Payout: 95%
Step-by-Step:
- Convert troy ounce to gram price:
$3,527.76 ÷ 31.1034768 = $113.42/gram - Calculate purity factor:
18K ÷ 24 = 0.75 (75% pure) - Calculate melt value:
10g × $113.42 × 0.75 = $850.65 - Apply payout percentage:
$850.65 × 95% = $808.12

How Our Calculator Works
📊 The Complete Formula
Step-by-Step Breakdown:
• Grams: No conversion needed
• Ounces: Weight × 28.3495
• Pennyweight: Weight × 1.55517
• Milligrams: Weight ÷ 1000
Troy Ounce Price ÷ 31.1034768 = Price per Gram
Example: $2,650 ÷ 31.1034768 = $85.20/gram
Karat ÷ 24 = Purity Factor
Example: 14K ÷ 24 = 0.583 (58.3% pure)
Weight × Price per Gram × Purity Factor
Example: 10g × $85.20 × 0.583 = $496.72
Raw Value × (Payout % ÷ 100)
Example: $496.72 × 0.90 = $447.05
