About Us

What we build

SpotGoldCalc provides free tools for estimating the precious-metal content and melt value of jewelry, scrap and selected U.S. silver coins. The calculators cover gold, silver and platinum.

How estimates work

We multiply the fine metal weight by the displayed spot price. Gold API is our default metals feed, with GoldAPI.io available as an alternate provider. Frankfurter supplies dated currency conversion rates. We show the source and time of the latest available quote.

Understanding the result

A melt value reflects metal content. A buyer may offer less after accounting for testing, refining and other costs. The payout slider lets you compare percentages before evaluating an offer.
