A gross-to-net salary calculator converts your annual or monthly gross salary (before deductions) into the net amount you actually receive after income tax and social security contributions are deducted. Tax systems vary significantly across EU countries — Germany's Steuerklassen, France's progressive income tax, Poland's flat-rate PIT, and the Czech Republic's "superhrubá mzda" each have unique rules.

InfraHub's EU Salary Hub implements 2026 tax brackets, social security rates, and contribution caps for Germany, France, Poland, and Czech Republic.

For each country, the calculator applies the country-specific tax schedule: progressive income tax brackets are applied in tiers (each bracket taxed at its marginal rate), social security contributions (pension, health insurance, unemployment) are calculated as percentages of gross salary up to applicable contribution ceilings. Germany additionally calculates Kirchensteuer (church tax) and Solidaritätszuschlag where applicable. The result is a breakdown showing each deduction category and the final net monthly and annual salary.

Software engineers comparing job offers across EU countries use it to compare true take-home pay after country-specific taxes. Recruiters use it to communicate realistic net salaries to international candidates. HR managers draft offer letters with accurate net salary estimates. Employees negotiating raises compare their current net pay to market benchmarks. EU citizens considering relocation use it to assess the financial impact of moving to a different country.
