About Kalkulo
Last reviewed:
Kalkulo.eu is a free network of country-specific financial calculators for salary, tax, VAT, loans, property, leave and benefits. Each market is maintained as a local page set with its own currency, terminology, rates and official-source context.
The site is built for practical, high-intent questions: "What will my net salary be?", "How much VAT is included?", "What does this mortgage payment look like?", "How many days of leave do I have?", or "Which small-business regime gives the clearer net result?". Those questions look similar across countries, but the rules behind them rarely are. Kalkulo keeps the calculator, explanatory content and source links tied to the market where the rule applies.
Publisher
Kalkulo is published by Cosmic Production d.o.o., a company registered in Croatia. The calculators and explanatory pages are maintained by the Kalkulo Editorial Team.
The publisher operates the site as an editorial and software project. Calculator logic, page structure, source references and update checks are maintained in the same codebase so changes can be reviewed, tested and deployed consistently across markets.
How the site is maintained
We use official tax, social security, central bank and government sources wherever possible. Calculator pages show their local data update date, source context and documented assumptions. The tools are informational estimates, not regulated tax, legal or financial advice.
- Each calculator belongs to one market and uses that market's locale, currency and terminology.
- Rate tables, thresholds and examples are checked against the calculation engine before publication.
- Important simplifications are described on the calculator page rather than hidden in the formula.
- Material changes are reflected in page copy, source references and the visible update date.
Coverage
Kalkulo currently covers payroll, income tax, VAT, self-employment, unemployment, leave, severance, loans, mortgages, property taxes, rental income and selected country-specific benefits or special regimes. The network is intentionally broad, but each page is meant to answer one local problem clearly rather than act as a generic encyclopedia article.
How Kalkulo is funded
The calculators are free to use. The site may be funded by advertising and, in future, by comparison pages for financial products where real provider data is available. Advertising does not change formulas, source checks or displayed assumptions. Privacy and consent details are explained in the privacy policy.
