Sick Pay Calculator UK
Our sick pay calculator helps you estimate how much you could receive while off work sick in the UK. It includes Statutory Sick Pay (SSP) for the 2026/27 tax year and also lets you model enhanced or occupational sick pay if your employer offers more than the statutory minimum.
This is useful if you want to estimate not just your statutory entitlement, but also what your employer sick pay policy could mean for your weekly income, monthly pay and estimated take-home pay.
What this sick pay calculator shows
This tool can estimate:
- Statutory Sick Pay (SSP) for the 2026/27 tax year
- SSP based on average weekly earnings and qualifying days
- Partial-week and multi-week sickness periods
- Employer sick pay using custom rule blocks
- Total gross sick pay over the absence period
- Weekly pay schedule
- Monthly payroll-style summary
- Estimated take-home pay after tax, National Insurance, pension and student loan deductions
How to use the sick pay calculator
Enter your salary details, choose your normal working pattern, and add the dates you are off sick. If you know your average weekly earnings, you can enter them directly. If not, the calculator can estimate them from your salary.
If your employer offers enhanced sick pay, you can switch on the employer sick pay section and build rule blocks such as full pay, half pay, a percentage of pay, a fixed weekly amount, SSP only or unpaid.
How Statutory Sick Pay is worked out
SSP is normally calculated using your average weekly earnings and the statutory SSP settings for the relevant tax year. The amount payable may depend on your earnings level, the length of sickness absence, and the number of qualifying days you usually work each week.
This calculator is designed for the 2026/27 tax year and uses the relevant SSP settings stored in your database, alongside the employer sick pay rules entered by the user.
Enhanced employer sick pay
Many employers offer sick pay that is more generous than SSP. For example, an employer may offer full pay for a number of weeks, followed by half pay, and then SSP only. Because employer policies vary, this calculator lets you model the rules that apply to your own situation rather than assuming a one-size-fits-all policy.
Important note
This calculator provides an estimate only. Actual sick pay can vary depending on your contract, employer policy, payroll dates, average earnings calculation, pension treatment, salary sacrifice arrangements, tax code, and other payroll-specific factors.
