How Our Calculators Work

The exact method and every rate behind the figures, so you can check the maths yourself.

The Starting Point: Gross Pay

Gross pay applies the confirmed 2026/27 award of 3.5% to the official September 2025 pay scales for England and Wales.

Police basic pay is set nationally, so a constable at a given pay point earns the same in every force. London Weighting and some South East allowances are added on top, and we let you include them by choosing your location. The official statutory determination for 2026/27 is not yet published, so these figures are accurate to within a pound or two pending that release.

Pension: PPS 2015

The PPS 2015 pension is charged on your pensionable pay, which is your basic pay plus London Weighting. It is taken before income tax, so you get tax relief at your highest rate. The contribution rate depends on your pensionable pay:

Pensionable payContribution rate
Up to £37,03512.88%
£37,036 to £79,58813.88%
£79,589 and above14.22%

Income Tax

Income tax is charged on your pay after the pension deduction. The bands for England, Wales and Northern Ireland are:

BandIncomeRate
Personal allowanceUp to £12,5700%
Basic rate£12,571 to £50,27020%
Higher rate£50,271 to £125,14040%
Additional rateOver £125,14045%

The higher-rate threshold is frozen at £50,270, so as pay rises a larger share is taxed at 40%. Above £100,000 the personal allowance is withdrawn by £1 for every £2 earned, which our calculators apply, creating an effective 60% band up to £125,140.

National Insurance

National Insurance is charged on your gross pay and is not reduced by your pension:

BandIncomeRate
Below primary thresholdUp to £12,5700%
Main rate£12,571 to £50,2708%
Upper rateOver £50,2702%

Student Loan

If you have a student loan, repayments are 9% of earnings above your plan threshold, or 6% for a postgraduate loan. The 2026/27 thresholds are:

PlanAnnual thresholdRate
Plan 1£26,9009%
Plan 2£29,3859%
Plan 4 (Scotland)£33,7959%
Plan 5£25,0009%
Postgraduate£21,0006%

Back Pay

When a force applies the award late, you are owed the difference between your old and new pay for each month you were paid at the old rate, backdated to 1 September 2026. We total those months, including the uplift to London and South East allowances, then show the figure after pension, tax and National Insurance. Because the arrears are paid in one month, PAYE can deduct heavily in that payslip before it evens out.

Overtime

Overtime is paid to constables and sergeants only, on basic pay, and is not pensionable. Your basic hourly rate is your annual basic pay spread across the standard working year, with the enhancement added on top:

CircumstanceRate
Standard overtimeTime + ⅓
Rest day, under 15 days noticeTime + ½
Public holidayDouble time

Because your basic salary already uses your personal allowance, overtime is taxed from the first pound, and at 40% once your total pay passes £50,270.

What We Assume

Unless you change them, our calculators assume the PPS 2015 pension, tax code 1257L, no student loan, no regional allowance and full-time hours. The take-home calculator lets you adjust all of these. Figures are estimates for guidance and are not financial advice. See our About page for our sources.
