Know what you'll actually take home before payday.
ShiftDue is a UK shift pay calculator built for the way shift workers really get paid — overtime, unsocial hours, bank holidays, NHS bands, pension tiers, tronc tips, the lot. Tap in your shift, see an honest take-home range in seconds.
— Who it's for —
• NHS staff (Bands 2 to 8b) — Section 2 enhancements, weekend/night/BH rates, and the right NHS pension tier picked automatically.
• Retail workers — premium pay for Sundays and Bank Holidays, weekly overtime, shift-origin-day rules so a 22:00–02:00 Sunday is paid as Sunday.
• Hospitality — tronc tips taxed for PAYE but exempt from NI (per HMRC), service charge taxed as wages, optional night/Sunday/BH premiums.
• Other shift jobs — flexible custom multipliers for weekday/Saturday/Sunday/Bank Holiday, plus weekly overtime thresholds.
— How it works —
1. Pick the vertical that matches your role.
2. Set your hourly rate (or pick an NHS band) and pension percentage.
3. Add a shift: date, start, end, break, optional public-holiday flag.
ShiftDue estimates gross pay and take-home as a sensible range, with PAYE, National Insurance, pension (Net Pay Arrangement or Relief at Source), and student-loan deductions for the 2025/26 UK tax year.

— Honest about estimates —
Every number is shown as a range, not a single figure. Take-home depends on your tax code, prior earnings in the year, employer pension scheme, and dozens of HMRC edge cases. ShiftDue gives a careful, transparent estimate — not financial advice.
Independent estimate. Not affiliated with NHS or any employer.
