📝 Statement Options
Quick answer: Since 6 April 2026, UK Statutory Sick Pay is payable from the first qualifying day of sickness, with no waiting days and no lower earnings limit. It is the lower of £123.25 a week or 80% of average weekly earnings, for up to 28 weeks. Enter pay over the eight weeks before sickness, tick the qualifying weekdays, and enter the absence dates: the tool works out average weekly earnings, the weekly and daily SSP rate (£24.65 a day for five qualifying days at the full rate), counts the qualifying days in the absence, applies the 28-week limit, and produces a PDF statement built locally with jsPDF. It assumes the absence qualifies, so it is a calculation aid, not legal advice.

UK Statutory Sick Pay Calculator – Complete Guide
Statutory Sick Pay changed more in April 2026 than in decades. The three unpaid waiting days are gone, the earnings threshold that used to lock lower-paid workers out is gone, and a new 80% cap applies to people whose pay is low. Any calculator or payroll template built before then is out of date.
SSP Before and After 6 April 2026
| Rule | Before 6 April 2026 | From 6 April 2026 |
|---|---|---|
| Waiting days | 3 unpaid days | None — paid from the first qualifying day |
| Lower earnings limit | Had to earn above a weekly threshold | Removed for SSP |
| Weekly amount | Flat £118.75 | Lower of £123.25 or 80% of average weekly earnings |
Figures reflect the changes under the Employment Rights Act 2025 and the regulations that brought them into force on 6 April 2026, as consistently reported by employment-law sources. Confirm the weekly rate at gov.uk each year.
Worked Example
| Employee | Average Weekly Earnings | Weekly SSP | Daily SSP (5 days) |
|---|---|---|---|
| Full-time | £400 | £123.25 (80% = £320, higher) | £24.65 |
| Part-time | £100 | £80.00 (80% of earnings) | £16.00 |
How This Calculator Actually Works
The tool divides the total pay you enter by the number of weeks to get average weekly earnings, takes 80% of that, and compares it with the statutory weekly rate; the smaller figure is the weekly SSP. It then divides that by the number of qualifying days you've ticked to get a daily rate. To count qualifying days in the absence, it walks through every date from the first to the last day and counts those that fall on a ticked weekday. The days payable are limited to 28 weeks' worth - 28 multiplied by qualifying days per week - less any days you say were already paid in the same linked period. SSP payable is the daily rate times the days paid. jsPDF then draws the statement as genuine vector text. Nothing ever touches a server.

Troubleshooting Common Issues
Explanation: 80% of the employee's average weekly earnings is below the statutory rate, so the lower figure applies. Solution: Check the pay total and number of weeks — this is expected for lower earners.
Explanation: Only dates falling on the ticked weekdays are counted. Solution: Check the weekday boxes match the employee's normal working pattern.
Explanation: There is no pay entered (so 80% of earnings is zero), no weekday ticked, or 28 weeks have already been used. Solution: Check the earnings, weekdays, and days already paid.
Explanation: The PDF needs both parties identified. Solution: Fill in both names, then download again.
Frequently Asked Technical Questions
Question 1: What actually builds the PDF - is it a known library?
Answer: This tool uses jsPDF, a widely used open-source JavaScript library for generating PDF documents in the browser, loaded directly in your browser tab.
Question 2: How are qualifying days counted within the absence?
Answer: It loops over each calendar date from the first to the last day inclusive and counts a date when its weekday matches one of the ticked qualifying days.
Question 3: How is the 28-week limit applied?
Answer: The maximum payable days equals 28 times the number of qualifying days per week, minus any days you enter as already paid; the days paid are the smaller of that remainder and the days counted in the absence.
Question 4: Why can the daily rate have fractions of a penny?
Answer: The weekly amount divided by the qualifying days doesn't always come out to whole pence (£123.25 over 3 days is £41.0833...). The tool multiplies the unrounded daily rate by days paid and rounds only the final total to the penny.
Question 5: Does this tool need an account, server, or API key?
Answer: No. jsPDF and the live preview both run as ordinary JavaScript already loaded by this page — you never need an account or any API key to use it.

£123.25 a week from 6 April 2026, up from £118.75. Lower earners receive 80% of their average weekly earnings if that is less.
SSP became payable from the first qualifying day of sickness, so the three waiting days were removed, and the lower earnings limit was abolished so that employees are no longer excluded because they earn too little.
SSP is the lower of the statutory weekly rate or 80% of the employee's average weekly earnings. Someone averaging £100 a week would receive 80% of that, which is £80 a week.
Using National Insurance liable pay over the eight weeks before the relevant date, divided by the number of weeks. This tool divides the total you enter by the number of weeks you enter.
The weekly SSP amount is divided by the number of qualifying days the employee works in a week. At £123.25 and five qualifying days, that is £24.65 a day.
Up to 28 weeks. This tool caps the days paid at 28 times the employee's qualifying days per week and lets you enter days already paid in the same period.
No. It assumes the absence qualifies and works out the amount. Conditions such as being incapable of work, notifying the employer, and providing evidence where required are not tested.
Yes. SSP is the statutory minimum, and many employers offer a more generous occupational sick pay scheme under the contract or staff handbook.
Final Thoughts
With waiting days and the earnings threshold gone, more people and more short absences now fall under SSP, which makes a quick, correct calculation more useful than ever. This tool shows each step of the working and produces a clear statement — all without employee details leaving your device.
