Why another fee calculator?

Most fee calculators were built once and abandoned — they still show 2023 rates. Ours are different: every rate lives in a versioned file with its effective date and official source, and an automated watchdog checks each platform weekly. When Whatnot or Depop changes a fee, we update within days, not years.
