One monthly payslip, reconciled
Annual salary £36,000 ÷ 12 = £3,000 gross. Assume the scheme uses qualifying earnings and takes a 5% employee contribution under the net-pay arrangement: (£3,000 − £520) × 5% = £124. The £520 monthly starting point follows the GOV.UK qualifying-earnings range of £6,240 to £50,270 a year. The employer's separate minimum 3% on the same base would be £74.40, paid into the pension, not deducted from your bank payment. Scheme rules can use a different earnings basis.
The standard 2026/27 Personal Allowance is £12,570: £1,047.50 for this illustrative even monthly calculation. Taxable pay after the pension is £2,876; £2,876 − £1,047.50 = £1,828.50 at 20% = £365.70 PAYE. Category A employee NI instead uses £3,000 gross: (£3,000 − £1,048 monthly primary threshold) × 8% = £156.16 NI. No income here crosses the £4,189 monthly NI upper earnings limit.
Bank pay = £3,000 − £124 − £365.70 − £156.16 = £2,354.14. That is a checkable steady-month illustration, not a promise that each month's PAYE will match it.
