Guides

Understand your payslip in seconds

Three deductions decide what lands in your account. Here is what each one is, in plain language.

PAYE

Income tax

Twenty per cent up to your standard rate band, forty above it. Your tax credits then come off the tax itself — not off your income.

USC

Universal Social Charge

A separate charge on your gross pay, in bands. No credits, no relief, and a pension contribution does not reduce it.

PRSI

Social insurance

Not really a tax: it buys entitlement to Illness Benefit, Jobseeker’s Benefit and the State Pension. Nothing below €352 a week.

NET

What actually lands

Gross minus the three deductions, plus anything you have agreed to — pension, bike-to-work, union dues.

%

Your next euro

The rate on additional pay. It is what decides whether overtime is worth it, and it is always higher than your average rate.

€/h

Your real hourly rate

Net pay divided by every hour you are away from home, unpaid breaks included. Usually a good deal lower than the rate on your contract.

Where do these figures come from?

Rates, bands, credits and labour rules live in one versioned file, each with its official source and the date a person checked it. Nothing updates itself.

Why pay for a calculator?

Because the rules move. Rates, bands and credits change every Budget, and PRSI changed part-way through 2026. Premium is what pays for somebody to check each figure against Revenue and keep the tools current.

The basic calculator stays free and unlimited, with no account.

A worked example: 6 hours of overtime at time and a half

Base rate €15 an hour, 39 normal hours.

Normal pay (39 h × €15)€585.00
Overtime (6 h × €15 × 1.5)€135.00
Gross for the week€720.00

The overtime premium alone — the extra above the normal rate — is €45.00.

How to read it

Irish law sets no overtime premium. There is no statutory time-and-a-half: the multiplier comes from your contract or a sector agreement, and some contracts pay the flat rate for extra hours. What the law does set is a limit — an average of 48 hours a week over four months. So the useful question is not "am I owed 1.5×?" but "what does my contract say, and am I over 48 hours?".

The figures in this example are produced by the same engine as the calculator above, using the 2026 tax year data. If a rule changes, they change here too.

Overtime calculator

Irish law sets no universal overtime premium — your rate comes from your contract or a collective agreement. Enter whatever applies to you: a multiplier such as time and a half, a flat hourly rate for certain days, or several different lines in the same week.

This is an estimate

The result is based on the figures you entered and the rules published for the selected tax year. Your actual pay depends on your Revenue record, your contract and your employer’s payroll.

Common questions

Is my employer obliged to pay time and a half?
Not by statute. The Organisation of Working Time Act 1997 regulates hours and rest, not overtime premiums. Any premium comes from your contract, a company policy or a collective agreement — check those first.
Is there a limit on how much overtime I can work?
Your average working week must not exceed 48 hours over a four-month reference period for most employees. Individual weeks can be longer, provided the average holds.
Why is the net value of overtime so much lower than the gross?
Extra pay sits on top of your normal income, so it is taxed at your marginal rate — which for many workers means 40% income tax plus USC and PRSI on that slice.
