1. What is Net Pay Calculation?

The net pay calculation determines take-home pay after deducting income tax and employee National Insurance contributions from gross pay. This calculator also provides information about employer NI rates (UK specific).

Explanation: The calculation shows the actual amount an employee takes home after mandatory deductions.
