About the global English version
The global section contains country-neutral calculators for users worldwide. It focuses on mathematical, financial, scientific, technical, business and everyday formulas that can be used independently of a specific national tax system. When a calculator uses money, enter all monetary values in the same currency.
How calculators are prepared
The catalog combines individual calculators with automatically generated calculation templates. Validation is ongoing; publication does not mean every formula has been independently expert-reviewed.
For financial, legal, health or jurisdiction-specific calculations, confirm the assumptions and current rules before relying on an estimate.
