About this calculator

This calculator works out statutory holiday entitlement and holiday pay under the UK rules it supports. It shows the arithmetic behind each answer, needs no account, and performs the calculation in your browser.

Method and sources

The calculations follow published GOV.UK and Acas guidance. The methodology page gives the formulas, worked examples, jurisdiction limits, rounding rules and links to the official sources.

Limitations

This is general information, not legal advice. It does not interpret individual contracts, calculate contractual enhancements, or cover every sector-specific scheme. The separate 12.07% method is limited to eligible irregular-hours and part-year workers in Great Britain; it is not presented as a rule for every worker or for Northern Ireland.

Corrections

Each calculation is checked against the cited official guidance and, where necessary, the underlying legislation and the official calculator. When a rule changes, the explanation and its boundary tests are corrected together, and the check date shown on each page is updated. If a figure here looks wrong, the “Report an error” link in the footer records it for review. It asks for no contact details and cannot be replied to; there is no contact form and no published email address.

Funding

The site is paid for by one advertisement on each calculator page, supplied by the ad network Adsterra. It sits below the result and above the explanations, never inside the calculator. The hosting platform does include a first-party script that counts visits in aggregate; the privacy page explains it. Advertising account identity and payment verification are private arrangements with a provider; they are separate from the public information this website must give its visitors.
