About Work Calculators
Free calculators for pay, leave and rights at work in the UK, using the rates in law and showing every step of the sum.
Who we are
Work Calculators is published by Youell Systems Ltd and edited by Max Youell. It went live on 13 November 2026. It is part of the same family as Energy Calculators.
We build calculators that answer one question each, properly. Every rate comes from GOV.UK, HMRC or legislation.gov.uk, and every result has a "Show the workings" button so you can check the sum yourself.
What we are not
We are not lawyers, an employer or a government service. Our calculators give information, not advice, and they work from what you enter. For advice about your own situation, Acas is free and independent. We do not sell your details and there is nothing to sign up to.
