Choosing the right calculator
Every calculator here uses the same live spot prices and the same transparent formula: weight in grams × purity × price per gram of pure metal × exchange rate. What changes is the question each tool answers. The gold, silver, platinum and palladium value calculators price a single item in any unit. The scrap gold calculator adds several items of different karats and applies a buyer payout percentage. The jewelry calculator adds making charges and tax to estimate a shop price, and the investment calculator compares what you paid with what your metal is worth today.
Looking for one karat only? Our gold price per gram by karat pages show live 9k, 10k, 14k, 18k, 21k, 22k and 24k prices with a prefilled calculator.
Tips for accurate valuations
- Weigh items in grams on a scale accurate to 0.01 g.
- Use the hallmark (585, 750, 916…) to choose purity.
- Compare the result with dealer quotes; melt value is the neutral benchmark.
