Methodology
How the calculator works
A plain-English explanation of every figure used to calculate your take-home pay.
Pay scales
All basic pay figures are taken from the 2025/26 pay circular issued following the Police Remuneration Review Body (PRRB) recommendation of a 4.75% uplift, accepted in full by the Home Secretary in August 2024. These figures apply to England and Wales. Scotland and Northern Ireland have separate arrangements.
The pay point labels (Year 1, Year 2, etc.) broadly correspond to years of service at that rank, though in practice progression may be subject to satisfactory performance assessment.
Income Tax (2025/26)
The calculator uses the standard 2025/26 income tax bands for England and Wales:
| Band | Taxable income | Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic Rate | £12,571 – £50,270 | 20% |
| Higher Rate | £50,271 – £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
Income tax is calculated on a marginal basis — you pay each rate only on the portion of income that falls within that band.
Where officers are enrolled in the Police Pension Scheme 2015, pension contributions are deducted from taxable income before income tax is calculated, meaning you receive full tax relief at your marginal rate.
The calculator assumes tax code 1257L. Officers with non-standard codes (e.g., K codes for underpaid tax from previous years, or codes for company car benefits) will see different income tax.
National Insurance (2025/26)
Employee Class 1 National Insurance contributions are calculated as:
| Earnings | Rate |
|---|---|
| Up to £12,570 | 0% |
| £12,571 – £50,270 | 8% |
| Over £50,270 | 2% |
NI is calculated on gross pay (including allowances) but is not reduced by pension contributions. The 8% rate was reduced from 10% in January 2024 and then to 8% in April 2024 following the Autumn Statement 2023.
Police Pension Scheme 2015 (CARE)
Contribution rates are determined by which band the officer's pensionable pay falls into. Unlike income tax, the rate applies to the full pensionable pay, not just the portion above the threshold:
| Pensionable Pay | Contribution Rate |
|---|---|
| Up to £27,047.99 | 11.00% |
| £27,048 – £51,515.99 | 12.44% |
| £51,516 – £150,000.99 | 13.44% |
| Over £150,001 | 13.78% |
Pensionable pay is typically basic pay plus London Weighting (where applicable). The detective allowance treatment varies by force.
Because contributions receive income tax relief, the net cost to a basic-rate taxpayer is approximately 80% of the headline rate. For a constable on 12.44%, the effective after-tax cost is around 9.95% of gross.
Student Loan Repayments
| Plan | Threshold (2025/26) | Rate above threshold |
|---|---|---|
| Plan 1 | £24,990 | 9% |
| Plan 2 | £27,295 | 9% |
| Plan 4 (Scotland) | £31,395 | 9% |
| Postgraduate | £21,000 | 6% |
Repayments are calculated on gross income and run concurrently with other deductions. Plan 2 is the most common — most officers who attended university after September 2012 will be on Plan 2.
Allowances
London Weighting: A flat £2,841/year added to gross pay for officers serving in the Metropolitan Police or City of London Police. This is pensionable.
Detective Allowance: An optional £1,800/year, available in some forces for qualified detective officers. Pensionability varies by force — the calculator treats it as pensionable for simplicity.
