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:
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).
Where the spot price comes from
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.
