Holiday Entitlement Calculator
Use this calculator for regular working patterns to choose the right holiday check first, then estimate entitlement in standard, starter or leaver mode.
Start by choosing the route that matches the real question. If the working pattern is irregular or part-year, stop here and use the official GOV.UK calculator instead of relying on a simplified estimate here.
Best when you want a full-year or simple pro-rata entitlement check for a regular weekly pattern.
Best when someone joined or is leaving part way through the leave year and you need a straightforward accrued-holiday view.
Irregular-hours and part-year workers are better served by the official GOV.UK calculator route.
Use this for a regular weekly pattern and a full-year or simple pro-rata check.
Use this when someone joined part way through the leave year and you want a straightforward built-up holiday estimate.
Use this when someone is leaving and you want a simple accrued-versus-taken balance before checking final pay.
Do not rely on this page for irregular-hours or part-year accrual. Use the official route instead.
Use GOV.UK insteadStandard mode is for regular-pattern entitlement. Starter mode is for built-up holiday after joining during the leave year. Leaver mode is for what may still need to be accounted for when the job ends.
The entitlement figure is not always the same as the money owed in final pay. Carry-over rules, holiday already taken, whether bank holidays are included, and the employer’s holiday policy can all change the practical outcome.
