Pro rata salary calculator
How the pro rata salary calculator works in Ireland
"Pro rata" means in proportion. To scale a full-time salary to part-time hours, multiply it by the share of full-time hours you work:
A €50,000 role advertised at 39 full-time hours, worked at 24 hours a week, pays €50,000 × 24 ÷ 39 = €30,769 — that's 61.5% of full time, or about €2,564 a month. No tax data is used, so the result never goes out of date.
This is the gross pro-rata figure. Drop it into the net salary calculator to see take-home pay after income tax, USC and PRSI.
