Scrap Gold Calculator Guide
Why Scrap Gold Value Changes
Scrap gold value moves with the gold market. It also changes with purity, weight, buyer terms, and refining cost. A heavy item is not always more valuable than a smaller one. Purity matters because only the fine gold portion is priced. This calculator keeps those parts separate, so each adjustment is easier to review.
Using Spot Price Correctly
The spot price is normally quoted per troy ounce. Many jewelry scales show grams or pennyweight instead. The calculator converts those units before valuing the metal. Enter the latest market price manually. Then select a currency label for your record. The tool does not change exchange rates.
Understanding Purity and Karat
Karat tells how much gold is inside the alloy. Pure gold is 24 karat. A 14 karat item contains about 58.33 percent gold. An 18 karat item contains 75 percent gold. Use the custom purity field when an assay gives a better number. This is useful for dental gold, mixed lots, or unusual alloys.
Buyer Payout and Deductions
Buyers rarely pay the full melt value. They may apply a payout percentage, a melt loss, a dealer margin, or a fixed fee. These fields help you compare offers before selling. A high spot price can still produce a weak offer when deductions are large. Check the net value, value per gram, and spread from gross value.
Practical Selling Tips
Weigh items carefully. Remove stones or non-gold parts when possible. Sort lots by karat before entering values. Keep receipts and test results with your calculation. Run several payout scenarios before accepting a quote. The best use of this calculator is comparison, not certification. Final payment depends on testing, refining, and local buyer policy.
