Support FinAdministrator
FinAdministrator gives you free, transparent take-home pay calculators for 14 countries — no sign-up, no paywall, no intrusive ads. Every tax figure is sourced from official government data, verified by hand, and updated for each tax year. That takes real time and real care.
If the calculators have helped you negotiate a salary, plan a relocation, or just understand your payslip, a one-time donation keeps the project running. Your support directly funds data verification, new country coverage, and server costs — so the next person searching "what is €50,000 after tax" gets a trustworthy answer too.
How your donation helps
- Data accuracy — every tax bracket, social contribution rate and allowance is cross-checked against its official government source. Donations fund the annual refresh cycle that keeps figures current.
- More countries — each new country means weeks of research, new calculator logic and thorough testing. Your support accelerates the roadmap.
- Ad-light experience — we keep advertising minimal. Donations let us sustain that choice without sacrificing quality.
- Open methodology — our full source list and calculation notes are published on the methodology page. Transparency is the product; donations protect it.
