Why I Built This I had some gold jewelry sitting around and wanted to know what it was worth. Simple right? I searched for "gold calculator" and tried a few sites. Most of them looked outdated—like they hadn't been updated in years. Some had prices that were clearly stale. Others were just lead capture forms pretending to be calculators. I couldn't find a tool that just worked: enter weight pick karat see value. That's it. So I built one myself. GoldCalc is what I wanted: clean interface live prices no nonsense. I added a few features along the way—multiple languages different currencies a dealer discount slider—but the core is still simple. It's free. No ads. No signup required. If you find any bugs or have suggestions let me know. I'm always improving it.
