Gold Calc Tool

Anyone selling gold to a local buyer runs into the same problem: the offer arrives as a single number with no explanation. GoldCalc gives you a baseline first. You enter the weight, the karat and your currency, and it applies the standard formula, weight times purity over 24 times the spot price, using a price it says it refreshes every 30 minutes. The page shows the per-gram price for 24K, 18K, 14K and 10K alongside the 24-hour change.

The dealer discount mode is the most practical part. Buyers don't pay full melt value, so you can switch on a 5%, 15% or 30% margin and see what a fair, typical or low offer might be. Knowing that 14K is 58.3% gold, or that a hallmark of 750 means 18K, also helps when a counter clerk names a figure.

The calculator handles grams, ounces, troy ounces, kilograms and pennyweight, 8K to 24K, and 18 currencies including USD, EUR, GBP, INR, JPY and BRL. Linked pages cover a cash-for-gold offer estimator, a scrap worksheet for adding up rings and chains before comparing offers, a melt value page, a hallmark lookup for stamps like 585, 750, 916 and 999, and a price hub by karat and weight. If a piece is stamped 925 or sterling, it points you to a silver calculator instead.

The guide below the calculator is worth a read before selling. It covers the difference between spot and bid prices, why a troy ounce isn't a regular ounce, and why local buyers usually run wider margins than online refiners.

The result is an estimate of metal value only, so it says nothing about a piece's craftsmanship, stones or collector value, and it depends on knowing your item's real weight and purity.
