Before you start
- Pro rata parameters are configured during your HR implementation. Before using this tool, check:
- Terms and Conditions are set up to include employees in pro rata calculations
- You know whether your holiday entitlement schemes are Days or Hours based
- You know whether your schemes include or exclude public holidays
- You know whether automatic pro rating is turned on in system configuration
When to run this tool:
- After holiday rollover, to pro rata new year balances for relevant employees
- After completing the Leaver workflow for any leaver with a pro rata adjustment - even if automatic pro rata calculations are enabled
How pro rata calculations work: Days vs Hours
- The calculation method depends on whether your Holiday Entitlement scheme is Days or Hours based.
Days - uses Work Days Factor (WDF)
- WDF = number of days worked per week ÷ normal working days (default: 5)
- Example: 4 days per week ÷ 5 = 0.8 WDF (80% of a full-time week)
- Days calculations assume the same hours each day and the same days each week. They're not suitable for employees whose work pattern doesn't meet this criteria.
Hours - uses FTE (full-time equivalent)
- FTE = hours worked per week ÷ normal full-time hours (from Job/Grade/Fixed amount)
- Example: 20 hours ÷ 38 hours = 0.53 FTE (53% of full time)
- When absence is booked, the exact hours from the employee's work pattern are deducted. Ciphr recommends Hours-based entitlement for part-time employees because of this accuracy.
-
Employees on complex work patterns MUST use Hours-based entitlement that includes public holidays. This applies to:
- Shift patterns with more than 5 days per week
- Shift rotating shift patterns
- 7-day flexi (CIPHRFLEXI) work patterns
- Putting these work patterns on a Days scheme is likely to calculate a WDF above 1, which would issue more holiday and public holiday entitlement than the full-time equivalent.

Important notes:
|
Set up Terms and Conditions
- Before pro rata calculations can run, Terms and Conditions must be configured to include employees.
- Go to Data Management > Code Tables
- Select the Job and Pay group, then select Terms and Conditions
- In the Absence section, enable the Include Employee in Pro-rata calculation? slider
- Employees on User Entered Holiday Entitlement are included in pro rata calculations by default, unless their Terms and Conditions have this slider disabled.
- You can also enable the Works on Public Holidays? slider here, but this is optional. It's not recommended where a mix of employees on those terms do and don't work public holidays.
Configure public holiday adjustments
A full-time employee is entitled to a fifth of their contracted hours per public holiday (one day = one fifth of a standard working week). There are two approaches depending on your holiday entitlement setup.
Public holidays not included in entitlement
Where public holidays (PH) are not included in the Holiday Entitlement (for example, a basic 20-day entitlement), the system calculates a pro rata adjustment based on the employee's work pattern. This applies where:
- WDF/FTE is not 1
- The employee doesn't work Monday-Friday
- The employee works public holidays
Any absence spanning a public holiday will not include that day or those hours.
How the calculation works:
The system calculates across the holiday year (period), broken down by Job and Pay record where there have been changes, and averaged. For Hours-based entitlement, it uses the Normal Hours in Day value from the Countries code table (linked to the employee via their Location). Where this isn't populated, a default (for example, 7.5 hours) set during implementation is used.
The Works on Public Holidays? setting in Terms and Conditions affects the adjustment as follows:
- True - PH adjustment is applied even if the employee is full time (WDF/FTE = 1), to compensate for worked PHs and any PHs that fall on non-working days
- False - PH adjustment compensates for PHs on non-working days, minus any PHs falling on working days (as those aren't worked)
Limitations of this approach:
- The system can't calculate an accurate PH adjustment for rotating or CIPHRFLEXI shift patterns where working days vary each week
- PH deductions may be inaccurate where an employee's daily hours differ from the Normal Hours in Day value
- Employees cannot book absence on a public holiday where PH are excluded from the scheme. This makes it unsuitable for employees who work public holidays, as they may want to book holiday over a PH or record other absence such as sickness. Employees who work public holidays must be on a scheme with Includes public holidays? enabled
- Recording absence over a PH will show a message like the one below where PH are not included in the Holiday Entitlement
Including public holidays in entitlement
Where the limitations above may apply, include public holidays in the Holiday Entitlement total (for example, 28 days overall). Pro rata calculations apply to the whole amount, so no separate PH adjustment is needed.
Any absence spanning a public holiday will include it. Hours-based schemes that include PH are most accurate for complex and CIPHRFLEXI work patterns, as the specific shift hours are deducted when absence is recorded.
Limitations of this approach:
- Where a PH falls on a working day and isn't worked, it must be manually entered - by the employee, manager, or HR in bulk using the Bulk Absence tool.
| Note: Bulk Absence isn't suitable for employees on a CIPHRFLEXI Work Pattern |
- Any absence spanning a PH WILL include them and a message like the one below will be displayed when recording one
- Entitlement may need amending where there are additional PHs in a year (for example, bank holidays for national events)
| Note: The Include Public Holidays? setting also applies to User Entered Holiday Entitlement. Consider who will be given this entitlement type, and whether to include PH in the total. Including PH is recommended to avoid additional PH adjustments being applied where they're not needed. |
- Hours schemes including PH are most accurate for more complex/FLEXI work patterns as the specific hours for each particular shift will be deducted when absence is recorded
System configuration options
Go to System Configuration > System Configuration to review and update pro rata settings. Use the Name column search to find each option quickly.
Automatic pro rating and precision
| Name | Description | Default value |
|---|---|---|
| Automatically pro rate holiday entitlement |
Triggers the pro rata holiday entitlement calculation when the current Job and Pay record FTE or Work Pattern is amended (dependent on whether Days or Hours based), the Holiday Entitlement scheme is changed within Absence Summary Totals, or a Refresh is applied in the Holiday Entitlement Code Table. If this is set to TRUE then any further change to an employee’s FTE or Holiday Entitlement will be automatically reflected in their holiday calculations Notes: When this is set to TRUE:
|
FALSE |
| Pro Rata calculation decimal places | Number of decimals for the value of pro rated holiday entitlement to be rounded | 2 |
| Pro Rata Tool days precision | Rounding of pro rated holiday entitlement when Days based. Entitlement will round up to X days | 0.5 |
| Pro Rata Tool Hours precision | Rounding of pro rated holiday entitlement when Hours based. Entitlement will round up to X hours | 1 |
Pro Rata adjustment visibility on Absence side bar charts
- The next key does not link to configuration but controls whether to display the Pro-rata adjustment on the employee’s Book & View Time Off/Absence Calendar pages (if there is an adjustment)
| Name | Description | Default value |
|---|---|---|
| Show Pro Rata Adjustment On Absence Summary SideBar | Show/Hide the Pro Rata Holiday Adjustment on the Absence Summary Side bar | TRUE |
Work Days Factor configuration
- There is one more key that is in the General group and relates to the Work Days Factor calculation for Days Holiday Entitlement
| Name | Description | Default value |
|---|---|---|
| Normal Working Days Per Week | Default working days in a week | 5 |
Run pro rata holiday calculations
- Go to Holidays & Absence > Absence Administration > Pro Rata Holiday Calculations
- Click Select Person Subset and build your subset of records
- Review the records displayed
| Tip: Full time employees with a WDF/FTE of 1 may still be included in pro rata calculations, eg where they don’t work Monday to Friday or work Public Holidays. To exclude them, filter by Personal Details - FTE = Less than 1 when creating your subset. |
| Note: The Works Public Holidays? indicator is driven by the Absence section of the employee's Terms and Conditions. Where a Holiday Entitlement code includes public holidays, there will be no separate PH adjustment - it's already built in to the pro rata figure. |
Colour key
Some rows in the list may have a colour if the following applies:
| Row colour | Description |
| Yellow | The employee already has a current manual holiday adjustment in the current holiday year. This would have been changed either via the Change Holiday Entitlement in Absence Summary or the Bulk Holiday Adjustment feature |
| Orange | Entitlement has been updated for the employee in this current holiday year |
| Pink |
A record may be excluded for one of the following reasons:

Export and check your data
- Before updating records, export the data to review calculations in detail.
- Click Pro Rata Export to download the spreadsheet
- Open the file and click Enable Editing so all calculations display correctly
- The spreadsheet has three tabs:
Header Summary
- This contains Pivot Table fields to summarise key data
- The third column shows the Average FTE/WDF Through Year used to calculate pro rata holiday entitlement
- Where someone has multiple Job and Pay records during the Holiday Year then this figure will be an average across the records, otherwise it will be the current FTE/WDF if this has not changed during the year
- The figure shown will vary depending on whether an individual is on a Days or Hours Holiday Entitlement type
- You can compare this against the respective column on screen
|
⚠ Important: The Average FTE/WDF Through Year is also used to calculate a pro ratacarried forward holiday limit, if you choose to permit this during holiday rollover. Therefore it’s essential to export the pro rata calculations before running the holiday rollover so you can check calculations, as the figures will be updated to the new year as part of the holiday rollover process so you will not be able to run it retrospectively For more information on Holiday Entitlement and Holiday Years please see the related guides. There is also a Holiday Rollover Toolkit available to walk you through the whole process |

Public holiday scenarios
- The following scenarios show how the system applies adjustments in practice.
Assumptions used in all scenarios:
- Public holidays in the year: 4 Mondays, 1 Wednesday, 3 Fridays = 8 days
- Standard daily hours: 7.5
- Full PH entitlement in hours: 8 × 7.5 = 60 hours
-
Traffic light colours indicate what's recommended
Scenario 1: A part time employee on a shift pattern
- Lucy works Monday to Wednesday (0.5 FTE – 19 hours per week) as follows:
- Monday 09:00–17:00 (half hour break) – 7.5 hours
- Tuesday 09:00–17:00 (half hour break) – 7.5 hours
- Wednesday 09:00–13:00 (no break) – 4 hours
- Lucy is on an Hours based Holiday Entitlement (HE) to ensure the correct amount of hours are recorded per absence, as her Wednesday hours differ to the other days
| HE includes PH | T&Cs works PH | PH adjustment | Notes |
|---|---|---|---|
| No | No |
(60 × 0.5 FTE) = 30 - (5 × 7.5) = 37.5 = -7.5 hours |
No PH included in the HE so the system calculates a pro rata amount of total PH, and then deducts any days that fall in the Work Pattern Negative PH adjustment occurs because Lucy is taking more than her pro rata PH entitlement Note: The system uses standard daily hours (7.5) from the Countries Code Table, which is inaccurate for the Wednesday where Lucy works only 4 hours |
| No | Yes |
60 × 0.5 FTE = 30 hours |
No PH included in the HE and Lucy works PHs, so no deduction is made Note: Not recommended as Lucy cannot book holiday or record other absence on PHs |
| Yes | No | None |
HE includes PH so no separate adjustment is needed Lucy must book time off for PHs in her Work Pattern as she doesn't work them: 5 days (4 Mondays and 1 Wednesday) or HR could add them via Bulk Absence Note: 5 days = 34 hours, which is less than the system-calculated value using standard daily hours, as it didn't account for the shorter hours on a Wednesday |
| Yes | Yes | None |
HE includes PH so no separate adjustment is needed Lucy only needs to book holiday for PHs she doesn’t work |
Scenario 2: A full time employee whose shift work pattern is not Monday–Friday
- Brian works Tuesday–Saturday (1 WDF) and is on a Days based HE
| HE includes PH | T&Cs works PH | PH adjustment | Notes |
|---|---|---|---|
| No | No | 4 days |
No PH included in HE, but even though WDF is 1, Monday is a non-working day so Brian is compensated Accurate as Brian is full time and works a 5-day week |
| No | Yes | 8 days |
No PH included in HE and Brian works PHs, so he is recompensed for the full amount Note: Not recommended as Brian cannot book holiday or record other absence on PHs |
| Yes | No | None |
HE includes PH so no separate adjustment needed Brian must book time off for PHs in his Work Pattern: 1 Wednesday and 3 Fridays, or HR could add them via Bulk Absence |
| Yes | Yes | None |
HE includes PH so no separate adjustment needed Brian only needs to book holiday for PHs he doesn’t work |
Scenario 3: A part time employee on a rotating shift pattern
Assan works a 4-day rotating shift pattern over 8 weeks, 8 hours per shift, averaging 28 hours per week (0.75 FTE)
Assan is on an Hours based HE so holidays are calculated by FTE
| HE includes PH | T&Cs works PH | PH adjustment | Notes |
|---|---|---|---|
| No | No |
(60 × 0.75 FTE) = 45 hours – (3 × 7.5) = 22.5 = 22.5 PH adjustment |
No PH included in HE, system calculates pro rata PH and deducts days in Work Pattern Tip: For a rotating shift pattern you can use the Absence Calendar/Planner to check where PHs fall on working days Note: System uses standard daily hours (7.5), which is inaccurate as Assan works 8-hour shifts |
| No | Yes |
60 × 0.75 FTE = 45 hours |
No PH included in HE and Assan works PHs, so no deduction Note: Not recommended as Assan cannot book holiday or record other absence on PHs |
| Yes | No | None |
HE includes PH so no separate adjustment needed Assan must book time off for PHs in his Work Pattern: 3 days for the PH that fall in his rotating shift pattern during the year, or HR could add via Bulk Absence Note: 3 days = 24 hours, more than the system-calculated value using standard daily hours of 7.5 rather than Assan's 8 hour shift |
| Yes | Yes | None |
HE includes PH so no separate adjustment needed Assan only needs to book holiday for PHs he doesn’t work |
