Everything about PRSI Contributions (Detailed)
📋Overview+
Calculates weekly PRSI contributions by class: Class A (standard employees), Class B (some public servants, modified rate) and Class S (self-employed, employee-only, with the annual minimum).
💡 Best practices
- Class B (modified rate, mainly pre-1995 public servants) is a niche class — its rates here are a lower-confidence estimate and should be confirmed against your specific payslip/pension scheme rather than relied on directly.

FAQ — PRSI Contributions (Detailed)
Which PRSI class am I in?+
Most private-sector employees are Class A, the standard class with both employee and employer contributions. Class B is a modified rate for some public servants, and Class S covers the self-employed. Pick the class from your payslip or your employment status.
Does self-employed PRSI include an employer share?+
No — Class S is an employee-only contribution, subject to an annual minimum. That is why the employer line shows nothing when Class S is selected.
How reliable are the Class B figures here?+
Treat them as an estimate only. Class B (mainly pre-1995 public servants) is a niche class, and its rates in this tool are lower-confidence — confirm against your specific payslip or pension scheme before relying on them.
