What is a 12-Month Rolling Sickness Calculator?
A 12-Month Rolling Sickness Calculator, also known as a rolling sickness calculator or rolling sick pay calculator, is a system used to measure employee sickness over the last 12 months on a rolling basis. In the NHS, it plays a key role in NHS absence tracking, NHS absence monitoring, and sickness absence management.
The calculator helps determine NHS sick pay, apply NHS attendance rules, and assess sickness entitlement NHS based on service-based sick pay and NHS service length sick pay. By following NHS guidance and official NHS guidance, organisations can accurately calculate paid sick leave NHS while staying within NHS policy limits.
How the 12-Month Rolling Sickness Calculator Works
The 12-Month Rolling Sickness Calculator NHS works by continuously reviewing sickness records from the previous year instead of resetting at the start of a calendar or financial year. First, staff or managers enter employee details such as length of service, previous absences, and the type of NHS sick leave taken.
This ensures correct classification of authorised sickness, special leave NHS, unauthorised absences NHS, or unpaid sickness exclusion. Each sickness episode is then recorded with accurate start and end dates. The calculator automatically performs sickness days calculation and absence days calculation, showing total sickness within the rolling sickness period.
These figures feed into NHS sick pay calculation rules, helping determine whether full sick pay NHS or half sick pay NHS applies and whether a sick pay reset NHS period has been reached. Managers can also use the tool for manager sickness tracking, allowing them to track sick leave NHS, improve staff absence monitoring, and clearly understand how is NHS sick pay calculated across different absence scenarios.
The calculator applies NHS attendance policies and NHS attendance rules to calculate sick pay entitlement NHS accurately. Many organisations integrate it with NHS HR tools, an NHS HR attendance tool, NHS payroll tools, or an NHS leave calculator to simplify sick leave management NHS.
When connected to an NHS absence management system, it becomes easier to calculate sick pay NHS, calculate paid sick leave NHS, and support accurate NHS workforce attendance monitoring, strengthening overall workforce planning and attendance management.
Calculation Example:-
Total Sickness Days (Rolling 12 Months): 3 days (January), 2 days (March), 5 days (May), 4 days (August) = 14 total sickness days. Total sickness within the rolling 12-month period = 14 days. NHS Sick Pay Outcome (Example Scenario): Assuming the employee is eligible for NHS sick pay and based on NHS service length rules where full sick pay entitlement equals 14 days and half sick pay applies after this limit.
Result: Days 1–14 → Full Sick Pay NHS, Total taken → 14 days, Entitlement exceeded? → No. The employee receives full sick pay for all 14 days of sickness. What Happens If More Sick Leave Is Taken? If the employee takes an additional 3 sickness days in September, the new rolling total becomes 17 days. Sick Pay Calculation: First 14 days → Full Sick Pay NHS, Next 3 days → Half Sick Pay NHS as per NHS policy.
Example:-
Total Sickness Days (Rolling 12 Months)
3 days (January)
2 days (March)
5 days (May)
4 days (August)
= 14 total sickness days
Total sickness within the rolling 12-month period = 14 days
NHS Sick Pay Outcome (Example Scenario)
Assuming:
The employee is eligible for NHS sick pay
Based on NHS service length rules:
Full sick pay entitlement = 14 days
Half sick pay applies after this limit
Result:
Days 1–14 → Full Sick Pay NHS
Total taken → 14 days
Entitlement exceeded? → No
👉 The employee receives full sick pay for all 14 days of sickness.
What Happens If More Sick Leave Is Taken?
If the employee takes an additional 3 sickness days in September:
New rolling total = 17 days
Sick Pay Calculation:
First 14 days → Full Sick Pay NHS
Next 3 days → Half Sick Pay NHS (as per NHS policy)
