Statutory Sick Pay Calculator 2026: Employer Guide

Statutory Sick Pay Calculator 2026 is no longer a niche payroll query. From 6 April 2026, employers must deal with first-day SSP, the removal of the Lower Earnings Limit gateway, and a new cap of £123.25 a week or 80% of average weekly earnings, whichever is lower. That combination changes both eligibility and calculation, so a manual spreadsheet that worked in 2025 can now produce the wrong answer. citeturn604805search0turn604805search3turn604805search6turn604805search15

This guide explains how an SSP calculator should work in practice, what figures payroll teams need before running it, where employers make mistakes, and how to document the result. It also shows how the 2026 rules interact with qualifying days, linked periods of incapacity for work, and payroll reporting.

What does a Statutory Sick Pay Calculator 2026 need to include?

A Statutory Sick Pay Calculator 2026 should not just multiply a weekly rate by the number of weeks absent. Under the 2026 rules, it must reflect three core changes:

• SSP is payable from the first full day of sickness absence
• the Lower Earnings Limit no longer blocks otherwise eligible employees from SSP
• SSP is paid at 80% of average weekly earnings or £123.25, whichever is lower citeturn604805search0turn604805search3turn604805search6turn604805search15

That means any calculator has to capture the employee’s average weekly earnings, the number of qualifying days in the week, the first day of sickness, and whether the absence forms part of a linked period.

What inputs should employers gather before calculating SSP?

Before using an SSP calculator, employers should collect:

1. the employee’s sickness start date
2. the employee’s qualifying working days
3. average weekly earnings in the relevant earnings period
4. whether any linked sickness periods exist
5. whether the employee meets the broader SSP eligibility conditions

The rate alone is not enough. A correct SSP result depends on the employee’s pattern of work and earnings record.

How do you calculate Statutory Sick Pay in 2026?

For 2026/27, the weekly SSP figure is the lower of:

• £123.25
• 80% of the employee’s average weekly earnings citeturn604805search0turn604805search6

Once that weekly figure is known, employers convert it into a daily rate based on qualifying days.

How is the daily SSP rate worked out?

The daily rate is the weekly SSP amount divided by the number of qualifying days the employee normally works in that week. If an employee has 5 qualifying days, the daily figure is the weekly amount divided by 5. If they work 3 qualifying days, divide by 3 instead. GOV.UK’s manual calculation guidance remains the basis for daily pro-rating, with the 2026 rules changing the weekly amount and when payment starts. citeturn604805search9turn604805search6

A common error is dividing by calendar days rather than qualifying days. That leads to underpayments or overpayments.

Who qualifies for SSP from 6 April 2026?

The 2026 changes make SSP available to more employees because the Lower Earnings Limit is removed as an eligibility barrier. Employers still need to consider whether the individual is an eligible employee and whether the sickness absence is long enough and structured in a way that triggers payment. citeturn604805search3turn604805search6turn604805search15

For many lower-paid and part-time workers, this is the biggest practical shift. Previously, an employee could be genuinely off sick but receive no SSP because earnings sat below the threshold. From 6 April 2026, that gateway falls away.

What is the effect of first-day SSP?

Before April 2026, employers had to deal with three waiting days in many SSP cases. From 6 April 2026, SSP starts from the first full day of sickness absence, so there is no waiting-day deduction for qualifying absences under the new rules. citeturn604805search3turn604805search6turn604805search15

That matters operationally because:

• sickness records must capture the first full sick day accurately
• payroll cut-off errors become more expensive
• line managers need to pass absence data to payroll faster
• return-to-work adjustments need cleaner audit trails

How should employers use an SSP calculator for linked absences and part weeks?

An SSP calculator 2026 must still deal sensibly with real-world payroll complications. These include linked periods of incapacity for work, part-week absences, irregular work patterns and mid-week payroll cut-offs.

For part weeks, employers calculate the weekly SSP amount first, then convert to a daily rate and pay only the qualifying sick days in that week. For linked absences, records must be complete enough to identify whether separate periods join together under SSP rules, because that affects entitlement duration and administration.

What records should payroll keep?

A defensible SSP process should keep:

• sickness start and end dates
• qualifying days
• average weekly earnings calculation notes
• the weekly SSP amount used
• the daily SSP calculation
• evidence of any linked periods
• RTI and payslip records showing the amount paid

This level of detail matters if an employee disputes pay or HMRC later asks how the figure was reached.

What are the most common Statutory Sick Pay calculator mistakes?

The most frequent errors in a Statutory Sick Pay Calculator 2026 are predictable:

• using the pre-April 2026 flat-rate mindset only
• ignoring the new 80% of AWE or £123.25 rule
• applying old waiting days
• forgetting that lower-paid eligible employees can now qualify
• dividing by the wrong number of qualifying days
• failing to preserve evidence for payroll and employee queries

These errors can create wage complaints, payroll corrections, or distrust in absence management.

SSP calculator checklist for employers

Use this practical checklist before finalising SSP in payroll:

• confirm the sickness starts on or after 6 April 2026
• verify the employee’s qualifying days
• calculate average weekly earnings correctly
• apply the weekly rule: 80% of AWE or £123.25, whichever is lower
• convert the weekly amount into a daily rate using qualifying days
• pay from the first full day of sickness absence
• keep a record of the calculation and source data
• check whether the absence links to an earlier SSP period
• review the payslip and payroll submission before final sign-off

Key takeaways

A Statutory Sick Pay Calculator 2026 must reflect the new April 2026 framework: first-day SSP, no Lower Earnings Limit gateway, and a weekly payment of £123.25 or 80% of average weekly earnings, whichever is lower. Employers should pair the calculator with clean absence records, qualifying-day data and documented payroll workings.
