Scrap gold value depends on weight, purity, and the payout percentage offered by a buyer. This guide breaks down the steps so you can estimate value quickly and compare offers.
Step 1: Weigh your gold
Use a scale that measures grams or troy ounces. Most calculators use grams, so convert ounces to grams when needed.
Step 2: Identify the karat
Karat shows how much pure gold is in your item. Higher karat means higher purity and higher value per gram.
Step 3: Apply spot price and payout
Start with the current gold price per gram, multiply by the karat purity, then apply the payout percentage (typically 80% to 95%).
Example formula
Spot Value = weightInGrams × pricePerGram × purity
Estimated Scrap Value = Spot Value × payoutPercentage
For a fast estimate, use the Scrap Gold Calculator and adjust the payout slider. You can also review the latest scrap gold price per gram before you compare offers.
