1. What is Monthly Net Pay Calculation?

The Monthly Net Pay calculation determines the actual take-home salary after deducting all mandatory contributions (income tax, ZUS, health insurance) from the gross annual salary in Poland for 2025.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Gross Pay} \) — Annual salary before deductions (PLN)

• \( \text{ZUS} \) — Total annual social security contributions (PLN)
