Uk Statutory Sick Pay Calculation

Estimate SSP based on tax year rates, average weekly earnings, qualifying days, and waiting day rules.

Expert guide to UK statutory sick pay calculation

Statutory Sick Pay (SSP) is the legal minimum amount many employees in the UK can receive when they are off work because of illness. If you are an employee trying to budget, a payroll manager preparing weekly runs, or a small business owner handling absences for the first time, understanding SSP accurately can save time, reduce payroll errors, and help avoid disputes. The rules look simple at first glance, but practical calculation often depends on several moving parts: average weekly earnings, qualifying days, waiting days, linked periods of sickness, and tax year rates.

This guide explains how UK statutory sick pay calculation works in plain English and shows the formula behind the calculator above. It also highlights common mistakes and gives practical examples you can compare with your own payroll setup. For the official legal and operational framework, always check GOV.UK guidance and statutory updates directly.

What SSP is and what it is not

SSP is a statutory payment made by employers to eligible employees who are off sick for at least 4 consecutive days (including non-working days). It is paid through payroll, usually in the same way as wages, with tax and National Insurance handled in line with normal pay processing. SSP is not the same as Occupational Sick Pay, which is an enhanced company policy some employers choose to offer on top of statutory minimums.

• SSP is set at a fixed weekly statutory rate for each tax year.
• Eligibility depends on meeting minimum earnings and employment criteria.
• SSP is paid for qualifying days only, not automatically for every calendar day.
• The first 3 qualifying days are usually waiting days and are unpaid, unless exceptions apply.

Current SSP rates and lower earnings threshold

The two core numbers that drive eligibility and payment are the SSP weekly rate and the Lower Earnings Limit (LEL) used for eligibility checks. Employees generally must earn at least the LEL on average to qualify for SSP.

Tax year	Weekly SSP rate	Lower Earnings Limit (AWE threshold)	Daily formula
2023-24	£109.40	£123	Weekly rate divided by qualifying days in week
2024-25	£116.75	£123	Weekly rate divided by qualifying days in week
2025-26	£118.75	£125	Weekly rate divided by qualifying days in week

Always validate rates each new tax year, especially if you maintain payroll templates, fixed spreadsheets, or internal policy notes. One of the most common payroll mistakes is leaving prior-year SSP figures in place after April.

How UK statutory sick pay calculation works step by step

1. Check eligibility by average weekly earnings: compare AWE to the LEL for the selected tax year. If AWE is below LEL, SSP is not payable.
2. Identify qualifying days: these are the days in the employee’s normal working pattern that count for SSP payment.
3. Apply waiting days: normally the first 3 qualifying days in a Period of Incapacity for Work are unpaid.
4. Calculate daily SSP rate: weekly SSP rate divided by qualifying days per week.
5. Calculate payable SSP days: total qualifying sick days minus waiting days (unless waiting days are already served in a linked period).
6. Multiply daily rate by payable days: this gives gross SSP before tax and NI deductions through payroll.

In formula form:
Daily SSP = Weekly SSP rate / Qualifying days per week
Payable days = Total qualifying sick days – waiting days
Total SSP = Daily SSP x Payable days

Worked examples for payroll teams and employees

Examples are useful because many misunderstandings come from mixing calendar days, working days, and qualifying days. In SSP, qualifying days are central.

Scenario	AWE	Qualifying days per week	Total qualifying sick days	Waiting days	Estimated SSP
Office worker, one absence period	£420	5	12	3	9 x (£116.75/5) = £210.15
Part-time worker, linked PIW	£250	3	6	0 (linked period)	6 x (£116.75/3) = £233.50
Low earnings case	£110	5	10	Not applicable	£0 (below LEL eligibility threshold)

Waiting days, linked periods, and why they matter

Waiting days are often the biggest source of confusion for employees. In a standard sickness period, the first 3 qualifying days are unpaid. However, if the employee has linked sickness periods that meet the statutory conditions, they may not need to serve waiting days again. This can significantly increase SSP in later absences. Payroll systems should store absence history accurately so linked periods are applied consistently.

A practical tip for employers is to use a clear internal rule: whenever a new sickness record is entered, check whether it links to an earlier qualifying period before finalizing pay. A quick review at input stage is easier than correcting overpayments or underpayments after payroll close.

Evidence, notifications, and payroll records

Employees are expected to notify employers of sickness according to workplace policy. Self-certification generally applies for short periods, and a fit note can be required for longer absences. Employers should maintain records of:

• Dates of sickness and return to work.
• Qualifying days and waiting day treatment.
• AWE calculations used for eligibility checks.
• Amounts paid as SSP and corresponding payroll periods.
• Any reasons for non-payment and employee communication.

Strong records are essential if there is a challenge to payment decisions, if payroll is audited, or if an employee requests clarification.

SSP and wider absence context in the UK

SSP sits inside a broader workforce health and productivity picture. According to official UK statistical releases, sickness absence rates fluctuate year to year, with major variation across sectors, occupation groups, and long-term health trends. This matters because policy and payroll pressure increase when absence rates rise. Employers with high exposure to frontline staffing or shift-dependent operations often feel this first.

Recent UK data from national statistics has shown that sickness absence can rise materially during periods of public health pressure and then moderate again. At business level, this means payroll and HR teams should build repeatable SSP processes, not one-off manual methods. A documented calculation workflow reduces risk during high-volume periods.

Common mistakes in statutory sick pay calculation

• Using calendar days instead of qualifying days when calculating payable SSP days.
• Forgetting waiting days on new absence periods.
• Applying waiting days again incorrectly when sickness periods are linked.
• Not updating annual rates after the new tax year starts.
• Ignoring AWE eligibility checks or using out-of-date earnings averages.
• Rounding inconsistently between payroll systems and manual checks.

Manual check method for confidence and audit

Even with payroll software, a manual reasonableness check is good practice. Use this quick framework:

1. Confirm tax year SSP rate and LEL.
2. Confirm employee AWE exceeds LEL.
3. Confirm qualifying days per week from working pattern.
4. Confirm total qualifying sick days in the absence period.
5. Confirm whether waiting days apply or have already been served in a linked PIW.
6. Compute daily rate and multiply by payable days.
7. Compare result with payroll output and investigate any mismatch.

This seven-step check takes only a few minutes and can prevent repeated payroll corrections.

Employee and employer planning tips

For employees

• Report sickness promptly and keep dates clear.
• Ask how your employer defines qualifying days in your contract or rota.
• Check whether company sick pay applies in addition to SSP.
• Review payslips and ask for a breakdown if your SSP seems lower than expected.

For employers

• Publish a short SSP policy with examples for managers.
• Train payroll and HR on linked periods and waiting day exceptions.
• Update statutory rates each April with a formal checklist.
• Keep communication consistent to reduce grievance risk.
