About
Tylias Calculator is a set of calculation tools published as a free service alongside tylias.com, the French sibling living at calculateur.tylias.com.
Editorial principle
Each tool answers one need and fits one page. We prefer an exact computation with its formula and limits to a flashy interface hiding the assumptions. When a simulator cannot produce a contractual figure — a net after tax, a loan offer, a health diagnosis — the page says so explicitly.
How the calculations run
Every computation executes in JavaScript, in the visitor's browser. No entered value is sent to a server. The formulas are the standard ones: constant annuities for loans, WHO thresholds for BMI, parameterised VAT rates, international definitions for units.
Stated limits
- Financial results are indicative and are neither investment advice nor a credit offer.
- Health results are informational and never replace a medical consultation.
- Collective agreements, personal taxation and local rules are not modelled.
Report an error
A disputable formula, an outdated rate, an inconsistent computation: report it through the contact page on tylias.com. Corrections are applied directly on the page concerned.
Funding
The site is funded by display advertising served through Google AdSense. Ads do not influence the tools' content, the order of results or the computed amounts.
