What Is a Job Share Salary Calculator?
A Job Share Salary Calculator is an online tool designed to help Irish employees and employers calculate pro-rata pay for part-time or shared roles.
In Ireland, job sharing means two people share the duties and pay of one full-time position. Your pro-rata salary is determined by the proportion of hours you work compared to a full-time schedule.
For example, if a full-time position is 37.5 hours per week and you work 18.75 hours, you earn 50% of the full-time annual salary.
This calculator makes those calculations simple, accurate, and instant — no spreadsheets or manual formulas needed.

How the Calculator Works
The calculator uses a simple formula to determine your pro-rata pay:
Pro-Rata Annual Salary = (Your Weekly Hours ÷ Full-Time Weekly Hours) × Full-Time Annual Salary
It then divides the annual figure by 12 months and 52 weeks to give your monthly and weekly salary.
Example:
If the full-time salary is €50,000 for 37.5 hours/week, and you work 20 hours:
Pro-Rata = (20 ÷ 37.5) × €50,000 = €26,666.67 per year
Monthly = €2,222.22 Weekly = €512.82
This formula follows Irish employment and HR standards for job share and part-time pay calculations.
