14k Gold Value Calculator

Understanding 14k Gold and Its Value
This calculator helps you estimate the intrinsic value of your 14k gold based on its weight, purity, and the current market price of pure gold. Understanding these factors is crucial when buying, selling, or appraising gold items.
What is 14k Gold?
Gold purity is measured in karats (k), where 24k represents pure gold (99.9% pure). 14k gold means that out of 24 parts, 14 parts are pure gold. The remaining 10 parts are other metals, typically copper, silver, nickel, or zinc, which are added to increase the gold's durability, hardness, and to alter its color.
Therefore, 14k gold has a purity of approximately 14 / 24 = 0.5833, or 58.33% pure gold. This is why it's often stamped with "585" or "14k".
How the Calculator Works
The calculator performs the following steps:
-
Unit Conversion: It first converts the entered weight into a standardized unit, typically troy ounces, as market prices are usually quoted per troy ounce.
- 1 Gram (g) = 0.0321507 Troy Ounces (oz t)
- 1 Pennyweight (dwt) = 0.05 Troy Ounces (oz t)
-
Purity Adjustment: It calculates the actual amount of pure gold by multiplying the total weight (in troy ounces) by the gold's purity percentage (58.33% for 14k).
Pure Gold Weight (oz t) = Total Weight (oz t) * (Purity in Karat / 24)
-
Value Calculation: Finally, it multiplies the weight of pure gold by the current market price per troy ounce.
Estimated Value (USD) = Pure Gold Weight (oz t) * Market Price (USD / oz t)
Key Inputs Explained:
- Weight of Gold: The total weight of your gold item (e.g., a bracelet, ring, or bullion). Ensure you use the correct unit.
- Purity of Gold: For this calculator, it's fixed at 14k (58.33% pure gold).
- Market Price per Troy Ounce: This is the fluctuating daily price of one troy ounce of pure (24k) gold. You can find this price from reputable financial news sites or precious metal dealers.
Important Considerations:
- Melt Value vs. Retail Value: This calculator estimates the "melt value" or intrinsic value of the gold content. It does not account for any craftsmanship, brand value, historical significance, or retail markup that might increase the item's overall selling price.
- Assay Costs: If you are selling gold to a dealer, they will often deduct a percentage for assaying (testing the purity) and refining costs.
- Market Fluctuations: Gold prices change constantly. Always use the most up-to-date market price for an accurate estimate.
This tool provides a solid baseline for understanding the raw gold value of your 14k items.
function calculateGoldValue() {
var weight = parseFloat(document.getElementById("goldWeight").value);

return;
}
var weightInTroyOunces = 0;
// Convert input weight to troy ounces
if (unit === "grams") {
weightInTroyOunces = weight * 0.0321507;
} else if (unit === "troyOunces") {
weightInTroyOunces = weight;
} else if (unit === "dwt") {
weightInTroyOunces = weight * 0.05;
}
// Calculate the proportion of pure gold
var goldProportion = purityKarat / 24;
// Calculate the weight of pure gold
var pureGoldWeight = weightInTroyOunces * goldProportion;
// Calculate the estimated value
var estimatedValue = pureGoldWeight * marketPricePerTroyOunce;
// Display the result, rounded to 2 decimal places
document.getElementById("calculatedValue").textContent = estimatedValue.toFixed(2);
