About Irish Money Clock
Irish Money Clock is a free, independent take-home pay calculator for PAYE employees in Ireland, paired with plain-English guides to the deductions that appear on an Irish payslip. It is built and maintained by one person in Ireland, and it is not affiliated with any government body, employer or financial institution.
Why it exists
Most salary calculators give you a single annual number. That is useful when you are comparing job offers, but it does very little to make the deductions feel real. Seeing that you will pay roughly €7,000 in income tax this year is abstract. Watching PAYE, PRSI and USC accumulate second by second while you are actually at work is not.
The clock was built around that idea: show the money arriving as it is earned, and show the deductions leaving at the same time. The guides came later, because it turned out the calculator raised more questions than it answered — why USC does not fall when you increase your pension, why a bonus is taxed so heavily, why a new job deducts far more than expected.
What the calculator does
You enter your salary and the period it covers, your weekly hours and your pension contribution percentage. From that it derives an hourly rate, then applies the 2026 single-person tax rules to whatever portion of time you have worked, updating several times a second.
It shows six figures: gross pay, pension, PAYE, PRSI, USC and net pay, along with net and gross rates per hour, day, week, month and year, and a year-to-date projection that assumes steady earnings from 1 January.
The assumptions it makes
Any live calculator has to simplify. These are the specific simplifications, stated plainly so you can judge how closely the output should match your payslip:
- Single person, standard credits. A combined personal and employee credit of €4,000 and a standard rate cut-off point of €44,000. Married, jointly assessed and single-parent situations all have different figures.
- Class A PRSI. A flat 4.2%, or a blended 4.2375% for annual estimates spanning a mid-year rate change. The PRSI credit for lower weekly earnings is not modelled.
- Standard USC bands with a €13,000 exemption threshold. Reduced rates for over-70s and medical card holders are not modelled.
- Pension relief against income tax only. Contributions reduce PAYE but not USC or PRSI, which mirrors the normal treatment of ordinary employee contributions.
- Smooth annualisation rather than cumulative payroll. Real PAYE is normally operated cumulatively, recalculating from year-to-date totals at each pay date. The clock spreads a full year of credits proportionally instead, which is why a single payslip will not reconcile to the cent.
- No overtime multipliers, benefit-in-kind, salary sacrifice, union fees or local property tax collected through payroll.
The clock is at its most accurate for a single PAYE employee on steady pay with an ordinary pension contribution, looking at annual or weekly figures. It is least accurate for anyone with variable pay, multiple employments, joint assessment, or a payslip in the middle of a cumulative adjustment.
Your data
The entire calculation runs in your browser. Your salary, hours and pension percentage are stored in your own browser's local storage so the page remembers your settings, and they are never transmitted to any server. There is no account, no sign-up and no salary database. Our privacy policy sets this out in full.
How it is funded
The site is free and intended to stay that way. Running costs are covered by advertising served through Google AdSense, concentrated on the calculator and guide pages where the content is. Google’s tag sits on every page because Google requires it to be readable there, but no advertising cookie is set and no ad is personalised unless you accept advertising cookies through the consent banner.
No advertiser has any input into the guides, and nothing on the site is a paid placement or affiliate link. If that ever changes it will be disclosed on the page in question.
Corrections
If a figure looks wrong, an explanation is unclear, or a rule has changed since a guide was written, please say so — corrections are welcome and are the fastest way to make the site more useful. You can reach us through the contact page.
