Assumptions and pay data
Pay data: Police pay (England & Wales). Sergeant: our estimate of £55,443 to £58,175 over 3 pay points, rates from 1/9/2026. Checked 8/10/2026.
- Full time is 40 hours a week.
- A 4-day week counts as 80% of full time and a 9-day fortnight as 90%: fewer hours for less pay. Compressed hours, where you work all 40 hours in fewer, longer days, keep full pay, so they need no calculation.
- Term-time only pay is your paid weeks over 52: the weeks you work plus your paid holiday. The box opens at 44.6 weeks (39 term weeks plus 5.6 weeks' holiday), 85.8% of full time, or £47,553 at £55,443.
- Annualised hours divide your yearly hours by 40 × 52 = 2,080. The box opens at 1,400 hours, 67.3% of full time, or £37,317 at £55,443. Annualised hours and Custom FTE stop at 95%.

Guide for Sergeant
This guide explains reduced and compressed working patterns for Sergeant on Sergeant at Police. Not every employer offers every pattern; use this for pay impact, then confirm eligibility with HR.
Reduced hours for Sergeant
This page models named patterns (four-day week, nine-day fortnight, term-time only, annualised hours) for Sergeant on Sergeant at Police. Pay is pro-rated from full-time Police pay (England & Wales) basic pay unless your contract uses a different formula.
Reduced and compressed hours
A four-day week is typically 0.8 FTE. A nine-day fortnight is 0.9 FTE (nine working days in ten). Term-time-only staff are paid for the weeks they work plus their paid holiday, spread across the year. Annualised hours contracts spread agreed hours across the year rather than fixed weekly patterns.
Employer variation
Not every employer offers every pattern. Some use a 0.89 FTE term-time formula for support staff. The calculator uses straightforward pro-rata from full-time band pay; your payroll may differ.

Frequently asked questions
Is a 4-day week the same as compressed hours?
No. Here a 4-day week means working 4 of your usual days, 80% of full time, so £55,443 becomes £44,354. Compressed hours means fitting your full 40 hours into 4 longer days, and your pay stays the same because your hours do not change.
What does a 9-day fortnight pay?
As reduced hours, 9 days in 10 is 90% of full time: £49,899 a year instead of £55,443, £5,544 less. If you work all 80 hours of the fortnight in 9 days instead, that is compressed hours and your pay does not change.
How is term-time only pay worked out?
From paid weeks: the weeks you work plus your paid holiday, divided by 52. With 39 term weeks and 5.6 weeks' holiday that is 44.6 weeks, 85.8% of full time, or £47,553 instead of £55,443. Your contract or payroll gives your exact number of paid weeks.
How do annualised hours work here?
You enter your contracted hours for the year and the calculator divides them by 2,080, which is 40 hours × 52 weeks. The 1,400 hours it opens with is 67.3% of full time, £37,317 a year. Anything above 95% of 2,080 hours is counted as 95%.
Do reduced hours change my leave and pension?
Yes, in proportion. Paid leave is pro-rated to your hours, and the annual leave calculator for a Sergeant works it out. Public service pensions are career average schemes, so your pension builds up on the pay you actually earn: 80% of the pay builds 80% of the pension for those years.
Are the results gross or net? Do you store my data?

We only collect your name and email if you choose to give them, for example to download your results or sign up for email updates.
