How It Works

Every calculator runs in your browser with modular formulas tuned to each country.

Choose your country and tool

Start from the homepage or a country hub such as Germany or the Netherlands. Each country page lists every calculator available for that market, from salary tax to monthly expense budgets.

Select the tool that matches your question — for example, net salary after tax, rent affordability, or VAT on an invoice.

Enter your figures

Forms use realistic defaults based on national averages and typical expat scenarios. Adjust gross salary, expense categories, interest rates, or VAT amounts to match your situation.

All processing happens locally in your browser. We do not store or transmit your financial inputs to our servers.

Review results and guidance

Results update instantly with breakdowns where relevant — tax components, category percentages, city comparisons, or yearly totals.

Below each calculator you will find country notes, expert tips, FAQs, and links to related tools for deeper research.

Accuracy and limitations

Formulas simplify real-world tax systems using published brackets, typical social contribution rates, and regional cost indices. Actual payslips, filings, and local rules may differ.

Tax law changes frequently. We review assumptions annually, but you should confirm critical decisions with a tax adviser or official authority.
