How we calculate NHS pay

The sums, the assumptions we make, and the gaps we know about.

Last reviewed 1 November 2026

Take-home pay

  1. Gross pay is basic pay for your band and pay point, pro-rated for part-time hours, plus the High Cost Area Supplement (England only) and any unsocial hours payments you enter.
  2. NHS Pension is a percentage of gross pay set by your pay tier. It is taken before income tax (a net pay arrangement) but not before National Insurance.
  3. Income tax uses the 2026/27 bands, with the personal allowance tapering above £100,000. Scotland uses the Scottish bands.
  4. National Insurance is calculated monthly at 8% between the primary threshold and the upper earnings limit and 2% above it.
  5. Student loan is 9% (6% for Postgraduate) of monthly pay above the plan threshold, rounded down to the pound.
  6. Take-home pay is gross pay less the four deductions.

Maternity and sick pay

Maternity pay follows the NHS occupational scheme (8 weeks full pay, 18 weeks half pay plus Statutory Maternity Pay, then SMP only) combined with the statutory rules. Sick pay uses the NHS scale by length of service and adds Statutory Sick Pay, which counts towards full pay and is added to half pay up to normal pay. Amounts are shown before tax.

Assumptions

  • Tax code 1257L, one job, no other income, no benefits in kind.
  • High Cost Area Supplement and unsocial hours payments are treated as taxable, subject to National Insurance and pensionable. This is our understanding and should be confirmed with your payroll team.
  • Pension tier is set from your actual annual pensionable pay, using the England tiers.
  • Pay is split into twelve equal monthly payments.

What is not covered yet

  • Wales and Northern Ireland pay scales.
  • Scottish pension contribution bandings (England tiers are used as an estimate and labelled).
  • Overtime, salary sacrifice and tax codes other than 1257L.
  • Occupational sick pay: the current Section 14 table could not be read in full, so the scale matches the handbook's first-year wording and several NHS trust policies. Half pay plus SSP, capped at full pay, is assumed.
  • Occupational maternity pay: England handbook wording was not available, so the Scottish guide is used.

Testing and corrections

Every rule is covered by automated tests whose expected values are worked out by hand from the official rates. When a rate changes we update the data, re-run the tests and record it in the change log. To report a mistake, see contact.
