03Calculation engine
Most online calculators do not fail because of the interface but because of a calculation nobody checks. We build the engine first – with tests against official reference values that block any deviating change.

06Fragen
Yes. We adopt your website’s colours, fonts and logo or design deliberately neutral – depending on where the calculator lives.
We check every calculation against reference values and document the sources. Professional sign-off and liability notes are agreed with you; a calculator does not replace legal or tax advice.
No, by default the browser does the calculation. If you want to receive enquiries, we add an explicit form – separate from the calculator.
Values sit in one place with source and year of validity. We swap them at the turn of the year; the tests show that everything else stays the same.
Send us the formula, a spreadsheet or an example. In the intro call we tell you how we would build it.
