How it works

  • Free, forever. No account, no API key, no fees — paste and go.
  • Lightweight & self-contained. One small iframe, no libraries to install, loads fast.
  • Always current. We maintain the freight-class logic, so your widget stays accurate automatically.
  • The only ask: keep the small “Powered by Freight Calculator Hub” link in place. That credit link is what keeps the tool free.
