The Formula
How We Calculate Gold Value
Gold value is calculated using a straightforward formula: Weight (in grams) × Karat Purity Percentage × Current Gold Spot Price Per Gram.
For example, if gold spot price is $60 per gram and you have 10 grams of 14K gold (58.3% pure), the calculation would be: 10g × 58.3% × $60 = $349.80 in gold value.
The challenge for most people is accurately determining the weight and karat of their gold. That's where our free professional evaluation comes in - we use XRF technology for precise readings.
