Enter the weight and purity of your gold item below to get an estimated gold content value based on the current reference price.

The Formula

To calculate the underlying gold content value, you need three numbers:

1. The current SGD price per troy ounce of pure gold — check current price
2. The weight of your item (in grams or troy ounces)
3. The purity of your gold (as a decimal)

Formula:
(Price per oz) ÷ 31.1035 × (Weight in grams) × (Purity) = Gold Content Value (SGD)

Purity Percentages (Karats)

• 24K (999.9): 99.99% (0.9999), see 24K gold guide
• 22K (916): 91.6% (0.916), see 916 gold guide
• 21K (875): 87.5% (0.875)
• 18K (750): 75.0% (0.750), see 18K gold guide
• 14K (585): 58.5% (0.585)

Example Calculation

Let's say you have a 10g 916 gold chain and the current price is SGD 5,797/oz:

1. Price per gram = 5,797 ÷ 31.1035 = SGD 186.38/g
2. Pure gold content = 10g × 0.916 = 9.16g of pure gold
3. Gold content value = 9.16 × 186.38 = SGD 1,707.24

Important Notes on Selling

When you sell gold to a dealer or pawnshop, the offer you receive will typically be below this calculated gold content value. The difference is the dealer's margin. It covers their testing, refining, operational costs and profit.

The actual percentage you receive depends on the product type, condition, and the dealer's assessment. Investment-grade bars with original packaging and assay certificates typically achieve tighter spreads than scrap jewellery. Rather than assuming a fixed percentage, request quotes from multiple dealers and compare.
