Pro rata holiday calculator

Estimate paid holiday entitlement in days or hours, with each step shown. This does not calculate holiday pay.

Enter your own figures and check the selected options. Results update automatically below as you type. Fields are required unless marked optional.

How your hours are set

Choose regular days for a fixed weekly pattern with days of equal length. Use hours worked for irregular-hours or part-year work, including term-time-only work. Starting or leaving a regular job is covered by the dates below.

Your working pattern

How many days you normally work each week.

How many days a full-time employee in the same role normally works each week.

Full-time holiday entitlement

The statutory minimum is weeks a year, capped at days. Many employers give more; the figure is in your contract.

Bank holidays

Check your contract: are bank holidays already included in the full-time entitlement you entered, or added separately? Confirm the selection below.

Use the number your employer adds for a full-time worker. Enter 0 if none. Leave blank if unknown; the result will exclude these days and be incomplete.

How to round the result

This calculator rounds up. Choose half or whole days to match how you want to view the estimate, then check your employer’s approach.

Part of the leave year (optional)

Leave blank for a full leave year. For a job starting or ending during the year, enter your employer’s leave year start date and the employment date that applies. A blank employment date uses the start or end of that leave year. Both dates are included; weekends count.

Your estimate

This calculator estimates holiday entitlement, not holiday pay or your remaining leave balance. It does not subtract holiday already taken.

How holiday entitlement is worked out

Almost every worker is entitled to weeks' paid holiday a year, capped at days. For someone on regular days, a week of holiday is the days they work in a week, so the entitlement is the weeks times the days: fewer days a week means fewer days of holiday, but the same number of weeks. The cap applies to the statutory minimum only. An employer that gives more than the minimum is not capped, and a part-time worker gets the same share of the extra. Pay is scaled the same way; the pro rata salary calculator works that out.

Bank holidays are not a separate right. An employer can count them inside the weeks or give them on top, and the contract says which. Where they are on top, a part-time worker should get a pro rata share of them whichever days they work, so that someone who never works Mondays is not worse off. This calculator shows the unrounded entitlement and a result rounded up to your chosen half or whole day. Check your employer’s rounding approach.

For leave years beginning on or after 1 April 2024, irregular-hours and part-year workers, including term-time-only staff, accrue holiday from the hours they have already worked, at the statutory weeks as a share of the working weeks in the year. Leave years are set by the employer and need not follow the tax year; someone starting or leaving part way through gets the entitlement in proportion to the days of the leave year they are employed. This page works out entitlement only, not holiday pay.
