How to read the model
How NettoFlow breaks down pay in Luxembourg
This page is not just a door into the calculator. It explains which tax and payroll layers matter most in Luxembourg and which inputs visibly change the result.
Income tax structure
Tax years, bracket thresholds, and filing logic decide how quickly gross salary turns into taxable income.
Payroll contributions
Pension, health, unemployment, and employer-side payroll costs change both take-home pay and full employment cost.
Local and personal settings
Regions, household status, children, or local surcharges can move the result materially even within the same country.

Calculator glossary
What the inputs mean for Luxembourg
These are the main fields you will see when you configure Luxembourg. Payroll is not driven by gross salary alone, so the guide explains the extra inputs too.
Gross Salary
Enter the gross pay before taxes and contributions. This is the starting point for net salary, employer cost, and comparison views.
Year
Select the tax year that matches the payslip or scenario you want to model. Thresholds, brackets, and contribution limits can change from year to year.
Tax Class
Use this setting when tax or payroll rules depend on your personal situation. It can change thresholds, reliefs, contribution rates, or the way salary tax is assessed.
Capital Gains
Use this field when you want to estimate salary and investment income in the same scenario. Capital-gains rules are often narrower than salary-tax rules.
