About UK Calculators

UK Calculators covers PAYE take-home pay, Income Tax and National Insurance, workplace pension contributions (including salary sacrifice), student loan repayment, contractor and IR35 take-home comparisons, and job-offer and housing-cost decisions — built specifically around UK tax and payroll rules rather than a generic international formula.

Built on current HMRC figures

Income Tax bands, the Personal Allowance and its taper, National Insurance thresholds, and Student Loans Company repayment thresholds are sourced from current gov.uk guidance and updated as new tax years are announced. Most calculators in this category use the England, Wales, and Northern Ireland rates — where Scotland's separate Income Tax bands would materially change a result, that's called out explicitly rather than assumed.

Estimates, not tax advice

Every calculator in this category is for informational and educational purposes only and is not tax, legal, or financial advice. PAYE withholding, workplace pension schemes, and individual tax situations vary — confirm specifics with a qualified tax professional, your employer's payroll team, or HMRC directly.
