Terms of use

Not professional advice

The calculators and explanatory material on this site are general information. They are not tax advice, legal advice, investment advice or financial advice, and using them creates no professional relationship of any kind. Your circumstances will contain facts these tools cannot see. Consult a qualified professional before acting.

Accuracy

Constants are checked against primary sources and dated on the page. Even so, tax law changes, agencies issue corrections, and some figures published here are explicitly flagged as projections rather than confirmed guidance. We make no warranty that any figure is current, complete or correct for your situation, and we accept no liability for decisions taken on the basis of an output from this site.

Acceptable use

You may use these calculators freely, personally or commercially, and link to them. You may not scrape the site at a rate that degrades it for others, misrepresent our figures as professional advice you have given, or republish the data tables as your own verified work.

Availability

The site is provided as-is with no guarantee of uptime, and any calculator may be changed, corrected or withdrawn without notice.
