Built to make pay decisions easier to understand.

Why this exists

Gross pay is almost never the number that matters. A job offer, a pay rise, a bonus, or a decision about salary sacrifice only becomes real when you can see what it means in your pocket. But the gap between gross and net involves income tax, National Insurance, student loans, pension contributions, and a handful of less obvious interactions — and most people encounter them without a clear explanation.

PayPath UK was built to close that gap. The aim is straightforward: give you a reliable, transparent reference figure so you can make better decisions before you commit to anything.

Who runs PayPath UK

PayPath UK is maintained by its founder, based in the UK. The site is not run by a firm of accountants, and it is not regulated financial advice. What it is: a carefully maintained reference tool, built and updated by someone who takes accuracy seriously and documents their assumptions.

How the calculators work

Every calculation uses HMRC's published rates and thresholds for the current tax year (2025-26). The methodology documents what is included, what is excluded, and how rounding is handled. Calculators are updated each April when the new tax year's rates take effect, and again mid-year if the Autumn Budget or an HMRC correction changes a figure.

What PayPath UK is not

It is not a payroll system. Your employer's payroll software operates under different rules — including tax codes, pay period adjustments, and employer pension contributions — and may produce a different figure. That difference is expected and normal.

It is not regulated financial advice. PayPath UK is not authorised by the Financial Conduct Authority. If you are making a significant financial decision — particularly one involving pensions, property, business income, or investments — speak to a qualified financial adviser or chartered accountant.

Transparency

Every assumption the calculators make is documented in the methodology. Every rate is sourced from HMRC publications. If something is wrong, there is a contact address and a genuine commitment to correcting it quickly. Privacy and cookie practices are documented in the Privacy Notice and Cookie Notice.
