Gold Price Per Gram — By Karat

How This Calculator Works — Formula & Method

Source: live spot feed, converted via live FX rate · applied deterministically · see full methodology

// 24K, 22K, 18K, 14K — read directly from the UK site's own published per-karat price
price_per_gram(karat, GBP) = UK_site.pricePerGram[karat]
price_per_gram(karat, USD) = price_per_gram(karat, GBP) × GBP_to_USD_rate
// 10K has no UK equivalent purity, so it's derived instead: 24K price × 0.417 fraction
total_value = price_per_gram(karat, USD) × weight_in_grams

Live spot price and live FX rate, not an AI estimate — updated three times daily. This is an indicative price, not a dealer quote. See the full methodology for why most karats are read directly rather than derived by fraction.

Frequently Asked Questions

The gold price per gram changes throughout the trading day. This calculator updates three times daily from a live spot price, so the figure shown is today's gold price per gram in USD, not a fixed historical value.
No. The price shown is the live spot rate — the wholesale market price. If you're looking to sell, pawn shops and gold buyers pay a discount to spot (see our cash-for-gold page), and the exact offer varies by buyer, purity and volume.
Gold's live feed here comes from a UK-based spot price provider, converted to USD using a live GBP-to-USD exchange rate. See our methodology page for the exact calculation and why this is disclosed rather than presented as a native USD feed.
In the US, gold jewelry is stamped directly with its karat — 24K, 22K, 18K, 14K or 10K — rather than a millesimal hallmark. 14K is the most common purity for everyday US jewelry; 10K is the lowest karat still legally sold as gold in most states.

US Karat Standards

Karat quality marks (24K/22K/18K/14K/10K) follow the FTC's Jewelry Guides (16 CFR Part 23) — the federal rules on gold fineness marking. See the FTC's own consumer guide, Buying Platinum, Gold, and Silver Jewelry, for what to check before buying.
