How this works
- Gross salary is reverse-engineered from your daily rate × working days, after deducting employer NI, apprenticeship levy, and umbrella fees.
- Working days are counted as every weekday (Mon–Fri) from your start date to the tax year end (2027-04-05), minus 9 England & Wales bank holidays that fall in that range, minus your vacation days. The result is the number of days you actually invoice for.
- Vacation defaults to 20 days pro-rated by the months in your contract (currently 20 days). You can override it manually. Vacation days reduce your working days and therefore your gross income — you are not paid for days you don't work.
- Employer NI is charged at 15% above the £5,000 threshold. The apprenticeship levy (0.5%) applies to the full taxable gross.
- Personal allowance (£12,570) is tapered by £1 for every £2 earned above £100,000 under tax code 1257L. Code 1257X applies the full allowance with no taper; BR taxes all income at 20% with no allowance.
- Salary sacrifice pension contributions reduce your gross before employer NI is calculated, saving both you and the employer NI. Relief at source contributions are shown as your net payslip cost after the provider's 20% top-up, and the gross contribution extends the basic-rate band in the tax estimate.
- NI and student loan thresholds are pro-rated when your contract doesn't cover the full tax year.
- This is an estimate. Actual figures depend on your umbrella company's exact payroll processing. This calculator does not constitute tax advice.
