About the calculation results

The results shown by the tools on this site are approximations based on the values you enter and the assumptions stated on each page. They do not reflect individual circumstances (health conditions, contract terms, working conditions, differences between municipalities or fiscal years, and so on).

The formulas and criteria of each tool are documented in the “How it is calculated” section of each page, with primary sources. When you need exact figures or decisions, always check with the public institution that issued the source, or a professional (doctor, tax accountant, licensed social insurance consultant, etc.).

Scope of responsibility

This site accepts no liability for any damage arising from the use of the information or calculation results on this site. Final decisions are your own responsibility.

Updates to information

Tools based on institutional rules (tax rates, insurance premium rates, assessment criteria, etc.) state their sources and the date of reference on each page. Rules change over time, so please also check the latest information at the source.
