Estimate your take-home pay
Use the Irish Net Salary Calculator to estimate PAYE, USC, PRSI, pension deductions, and monthly take-home pay.
Quick answer
- Take-home pay is usually gross pay minus Income Tax, USC, PRSI, pension contributions, and other payroll deductions.
- Income Tax uses 20% and 40% bands, then tax credits reduce the Income Tax bill.
- USC and PRSI are calculated separately, so do not subtract tax credits from every deduction.
- A salary calculator is fastest for estimates, but your payslip is based on exact payroll records.

The simple take-home pay formula
The simple formula is: gross pay minus Income Tax, USC, PRSI, pension contributions, and other payroll deductions. The tricky part is that each deduction uses different rules. Income Tax uses bands and credits, while USC and PRSI follow their own thresholds and rates.
Why monthly and annual results differ
A calculator usually annualises your pay and then converts the result back to monthly, weekly, or fortnightly figures. Real payroll uses exact pay dates, rounding, Revenue records, and pay-period rules, so small differences are normal.
When a calculator is enough
A calculator is useful for comparing job offers, checking a pay rise, planning a pension contribution, or estimating take-home pay before accepting a role. If your payslip looks wrong, the next step is checking your Revenue myAccount record and employer payroll details.
Frequently asked questions
How do I calculate take-home pay from gross salary?
Estimate Income Tax, USC, PRSI, pension, and other deductions, then subtract them from gross pay. A calculator does this faster.
Is net pay after tax?
Yes, net pay is the amount left after tax and other payroll deductions have been taken.
Why is my monthly net pay different from annual divided by 12?
Payroll timing, rounding, bonus payments, credits, Week 1 basis, and deductions can all change period-by-period results.
Is this guide tax advice?
No. It is general information for planning. Use official guidance or a tax adviser for your own situation.
Can I use the calculator for filing?
Use it as an estimate only. Complex activity such as DeFi, staking, mining, business trading, or many swaps may need specialist software or advice.
