How Gold Selling Rates Are Calculated
Selling gold is different from buying it. When you sell gold to a dealer, jeweler, or refinery, the price is determined by four primary factors: the current market spot price, the purity of the item, the total weight, and the dealer's margin (often called the spread).
The mathematical formula used by this calculator is:
Selling Price = (Weight in Grams × (Spot Price per Ounce ÷ 31.1035) × Purity Percentage) × (1 – Dealer Fee %)

Tips for Getting the Best Selling Rate
Know the Weight: Always weigh your gold in grams before visiting a buyer. Use a digital scale for accuracy.Separate by Karat: Don't weigh 14K and 18K items together. A buyer might pay you at the lowest karat rate for the entire lot.Check the Spot Price: Gold prices fluctuate by the minute. Check a live ticker before you walk into a shop.Understand the Spread: Most local "Cash for Gold" shops pay between 60% to 80% of the melt value. Online refineries may pay 90% to 95%.
Realistic Example Calculation
If you have a 10-gram ring made of 14K gold and the current spot price is 2,000 per ounce:
Price per gram: 2,000 / 31.1035 = 64.30 per gram.Pure gold content: 10g × 0.583 (14K) = 5.83g of fine gold.Melt Value: 5.83g × 64.30 = 374.87.Dealer Payout (at 10% fee): 374.87 – 10% = 337.38.
function calculateGoldValue() {
var weight = parseFloat(document.getElementById('goldWeight').value);
var purity = parseFloat(document.getElementById('goldPurity').value);
var spotPrice = parseFloat(document.getElementById('spotPrice').value);
var feePercent = parseFloat(document.getElementById('dealerFee').value);
// Error handling
if (isNaN(weight) || weight <= 0) {
alert("Please enter a valid weight.");
return;
}
if (isNaN(spotPrice) || spotPrice <= 0) {
alert("Please enter a valid spot price.");
return;
}
if (isNaN(feePercent) || feePercent 100) {
alert("Please enter a valid dealer fee percentage (0-100).");
return;
}
// Calculations
// 31.1034768 grams in a Troy Ounce
var gramsInOunce = 31.1035;
var pricePerGram = spotPrice / gramsInOunce;
var meltValue = weight * purity * pricePerGram;
var feeAmount = meltValue * (feePercent / 100);
var finalPayout = meltValue – feeAmount;
// Displaying Results
var resultBox = document.getElementById('goldResultBox');
var payoutDisplay = document.getElementById('payoutDisplay');
var breakdownText = document.getElementById('breakdownText');
resultBox.style.display = 'block';
payoutDisplay.innerText = finalPayout.toLocaleString(undefined, { minimumFractionDigits: 2, maximumFractionDigits: 2 });
var purityLabel = document.getElementById('goldPurity').options[document.getElementById('goldPurity').selectedIndex].text;
breakdownText.innerHTML = "Based on " + weight + "g of " + purityLabel + " gold. Full Melt Value: " + meltValue.toFixed(2) + " | Dealer Fee Applied: " + feeAmount.toFixed(2);
