Method notes
Calculations are educational models for planning conversations. They are not payroll, lender underwriting, medical diagnosis, or tax authority determinations. Local law, fees, and rounding differ. Always verify with official sources and professionals for YMYL decisions.
Prefer the country pack that matches you (e.g. /us/, /uk/, /jp/) so tax and currency defaults fit.
