Holiday owed and leaving-work tool

Holiday Entitlement Calculator

What this tool helps you check

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.

Use standard mode

Best when you want a full-year or simple pro-rata entitlement check for a regular weekly pattern.

Use starter or leaver mode

Best when someone joined or is leaving part way through the leave year and you need a straightforward accrued-holiday view.

Use GOV.UK instead for irregular work

Irregular-hours and part-year workers are better served by the official GOV.UK calculator route.

Standard

Use this for a regular weekly pattern and a full-year or simple pro-rata check.

Starter

Use this when someone joined part way through the leave year and you want a straightforward built-up holiday estimate.

Leaver

Use this when someone is leaving and you want a simple accrued-versus-taken balance before checking final pay.

Irregular or part-year

Do not rely on this page for irregular-hours or part-year accrual. Use the official route instead.

Use GOV.UK instead
Start with the route that matches the real question

Standard 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.

Important:

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.

This page is strongest when the pattern is regular and the question is simple. If the real issue is a mixed final package, move to the final-pay page after using the result here.

Recheck when

Work pattern, leave year, starter or leaver dates, or irregular-hours rules change

Pick the lane before you calculate

Choose standard mode for a regular full-year check, starter mode for joining part way through the leave year, and leaver mode for a simple accrued-versus-taken balance on a regular pattern.

Use the final-pay page next if you are leaving a job

That is usually the better next step when you need to understand how unused holiday, notice pay and other items fit together in the last payment.

Use the notice page when holiday is not the only issue

If the dispute is really about when employment ends, notice owed, or pay in lieu, check notice separately after using this page.

Use the official GOV.UK route instead for irregular or part-year patterns

Irregular-hours and part-year holiday calculations are better handled by the official calculator rather than this simpler page.

What this route helps you answer

  • How much statutory holiday a regular weekly pattern builds up.
  • Whether a simple starter or leaver estimate suggests holiday may still be owed.
  • Whether bank holidays are likely already inside the allowance being checked.

Switch route when

  • The hours or working year are irregular.
  • You mainly need to understand the whole final payslip rather than holiday alone.
  • The dispute is really about holiday pay rate, deductions or contract wording.
Quick questions before you calculate

Choose the right holiday route first

When should I stay on this page?

Stay here when the working pattern is regular and the main question is a simple entitlement, starter or leaver check.

When should I switch to final pay?

Switch to final pay when holiday is only one line in a bigger leaving-work package with notice, wages, deductions or settlement wording.

When should I use GOV.UK instead?

Use GOV.UK when the worker is irregular-hours, part-year, or the accrual pattern is too uneven for a simple weekly-days estimate here.

What does leaver mode actually help with?

Leaver mode is a quick first check for whether holiday may still be owed or may already have been taken ahead before you check the final payslip properly.
