About & methodology

GoldGramPrice shows the melt value of gold — the worth of the raw metal content — at today's spot price. It is a reference tool, not a dealer and not investment advice.

The formula

Every value on this site is computed the same way:

melt value = ( spot price ÷ 31.1035 ) × purity(karat) × weight(grams)

Purity by karat:

  • 24K Gold — 99.90% pure (fineness 999)
  • 22K Gold — 91.67% pure (fineness 916)
  • 18K Gold — 75.00% pure (fineness 750)
  • 14K Gold — 58.50% pure (fineness 585)
  • 10K Gold — 41.67% pure (fineness 417)

For pennyweight, use 20 dwt per troy ounce instead of 31.1035 g. Current spot used across the site: $4,156.70/troy oz (live feed).

Source

Spot prices are fetched from a third-party precious-metals API (Metal Price API or GoldAPI) by an automated weekly pipeline. Each refresh stamps a visible "last updated" time and source badge so you always know how fresh the number is. Until an API key is configured, the site displays clearly-labeled sample values.

What melt value is not

  • Not an offer to buy or sell. Dealers pay a percentage of melt and set their own terms.
  • Not numismatic/collectible value. Rare coins and designer pieces can be worth far more than melt — we do not assess that.
  • Not investment advice. Spot prices lag the live market and can be delayed or inaccurate.

How the site stays fresh

An agent pipeline runs weekly: it pulls the latest spot prices, recomputes every per-karat value, appends a row to the price history, and proposes new content (city pages, dated "gold price today" pages, buyer-guide articles) into a human-reviewed queue. Price data refreshes automatically; anything touching money, offers, or legal claims is reviewed by a person before it ships.
