About Beezbook

Beezbook builds everyday calculators for Korea, the U.S., and Japan — take-home pay, taxes, benefits, housing costs — with one obsession: the rates behind every number must be verifiable. Each calculator cites its official sources, and we monitor 20 government sources daily (Federal Register, Korea's national law database, Japan's e-Gov) for changes.

Everything runs in your browser. No sign-up, no server-side storage of your inputs.

Not professional advice

Results are estimates for general information, not tax, legal, or financial advice. Beezbook is not affiliated with any government agency. For decisions, consult the official source or a licensed professional.
