Understanding Old Gold Valuation

When you sell old gold jewelry, the price you receive is rarely the "spot price" seen on financial news. Jewelry is usually made of alloys (22k, 18k, etc.) rather than pure 24k gold. Our Old Gold Rate Calculator helps you determine the actual cash value based on three critical factors: weight, purity, and melting loss.

How the Calculation Works

To find the value of your gold, we use the following mathematical formula:

Final Value = (Total Weight × (Karat / 24) × Current Market Rate) – Wastage Percentage

Key Terms to Know

  • Karat (K): This measures the purity. 24K is 99.9% pure, 22K is 91.6% pure, and 18K is 75% pure. The higher the karat, the higher the payout.
  • Current Market Rate: This is the live price of 24k gold per gram in your local currency.
  • Wastage/Melting Loss: Jewelers often deduct a small percentage (usually 2% to 6%) to account for the solder, impurities, and loss during the melting process.

Example Calculation

Suppose you have a 10 gram necklace that is 18K gold. If the current 24K market rate is $60 per gram and the jeweler charges a 3% wastage fee:

  1. Pure gold calculation: 10g × (18/24) = 7.5 grams of pure gold.
  2. Market Value: 7.5g × $60 = $450.
  3. After 3% Wastage: $450 – $13.50 = $436.50 Final Value.
function calculateOldGoldValue() { var weight = parseFloat(document.getElementById("goldWeight").value); var karat = parseFloat(document.getElementById("goldKarat").value); var rate = parseFloat(document.getElementById("currentRate").value); var wastagePercent = parseFloat(document.getElementById("wastage").value); if (isNaN(weight) || weight <= 0) { alert("Please enter a valid gold weight."); return; } if (isNaN(rate) || rate <= 0) { alert("Please enter the current market rate for 24K gold."); return; } if (isNaN(wastagePercent) || wastagePercent < 0) { wastagePercent = 0; } // 1. Calculate Pure Gold Equivalent var purityRatio = karat / 24; var pureWeight = weight * purityRatio; // 2. Calculate Gross Market Value var grossValue = pureWeight * rate; // 3. Apply Wastage Deduction var wastageAmount = grossValue * (wastagePercent / 100); var netPayout = grossValue – wastageAmount; // Display Results document.getElementById("pureWeightResult").innerText = pureWeight.toFixed(3) + " g"; document.getElementById("grossValueResult").innerText = formatCurrency(grossValue); document.getElementById("wastageResult").innerText = "-" + formatCurrency(wastageAmount); document.getElementById("finalPayoutResult").innerText = formatCurrency(netPayout); // Show the result section document.getElementById("goldResultSection").style.display = "block"; } function formatCurrency(num) { return "$" + num.toLocaleString(undefined, { minimumFractionDigits: 2, maximumFractionDigits: 2 }); }
