Formula and scope

Use the shared employee insurance calculator and existing wage-tax engine on monthly taxable salary. Annual estimated income tax is divided by 12; local tax is 10% of income tax. Annual net is monthly net × 12, holding the selected half-year pension limits constant for all months.

What this calculator cannot apply

Not an official withholding-table lookup or payslip. Bonuses, severance, monthly changes, partial-year employment and year-end settlement are excluded. Verify non-taxable pay and dependent eligibility yourself; insurance exemptions and settlement are separate.
