Gold Karat Calculator and Price Per Gram Estimate
Use this calculator as an estimate of gold content by karat and weight. It is not a live gold price, quote or guaranteed offer. Final valuations depend on testing, actual weight, purity and item-specific factors.
Estimate Your Gold Content Value
Estimate only. Enter your own 24ct reference price if you want a metal-content value. This is not a live price, payout or offer.
Formula Behind the Estimate
A simple estimate is: weight x purity percentage x reference price. For example, 9ct is 37.5% gold, 14ct is 58.5%, 18ct is 75%, 22ct is about 91.6%, and 24ct is close to pure gold.
Why Final Offers Differ
Final offers can differ because of scale weight, actual purity, stones, condition, coin premiums, packaging, refining costs and the reference market price at the time of valuation.
