PAYE Calculator
Estimate your take-home pay under a simple PAYE setup using your gross income, tax rate and other common deductions.
Overview
This PAYE calculator helps you estimate take-home pay from your gross income using a chosen pay frequency, personal allowance, income tax rate, National Insurance rate and pension contribution rate. It is useful for quick salary comparisons and simple budgeting.
How it works
The calculator first converts your gross pay into an annual figure based on the pay frequency. It then subtracts your personal allowance to estimate taxable pay. Income tax is calculated on the remaining taxable amount using the rate you enter, while National Insurance and pension are estimated as percentages of annual gross pay. Net pay is the annual gross pay minus these deductions.
