Methodology and sources

How our calculators work, what they include and what they leave out.

What the calculators do

Our tools apply published tax brackets, contribution rates, VAT rates and standard financial formulas to the numbers you enter. All calculations run in your browser.

Data and sources

Tax and contribution rules are based on publicly available government and tax authority information for the year stated on each page. Currency rates are European Central Bank reference rates. Rules change often, so figures can be out of date.

What is simplified

Net salary and freelancer results are estimates for a single person without children and exclude regional taxes, church tax, special regimes and individual deductions. Mortgage and loan results use the standard annuity formula and exclude fees and insurance.

Not professional advice

Results are for information and planning only. They are not tax, legal or financial advice. For important decisions, confirm figures with official sources or a qualified adviser.
