Terms of use
The calculators are informational. Results are estimates based on the rates in force and must not be used for official, legal or employment decisions.
Informational use only
The calculators on this site are informational tools. The rates they apply are the ones in force, taken from named primary sources and cited where they appear; if a rule changed recently it may not be reflected here yet, and none of them has been through our final sign-off. The result is an estimate, not an official, legal, tax or employment determination — for the amount that binds you, use the cited source, your employer or a qualified adviser.
No warranty
The site is provided as-is, without warranty of accuracy or fitness for a particular purpose. For the amount that binds you, refer to your employer or the responsible authority. Last updated: aug 2026.
