How this was worked out

1. Salary: £42,000
2. Personal allowance: £12,570. Payroll applies it as tax code 1257L, which gives £12,579 of tax-free pay.
3. Taxable income: £42,000 − £12,579 = £29,421
4. Basic rate: £29,421 × 20% = £5,884.20
5. Income tax: £5,884.20
6. National Insurance: (£42,000 − £12,570) × 8% = £2,354.40
7. Take-home pay: £42,000 − £5,884.20 − £2,354.40 = £33,761.40

A five per cent pension on 42k

Salary sacrifice at five per cent moves £2,100 of £42,000 into a pension and leaves take-home of £32,249.40. Your employer also saves £315 of its own National Insurance on the sacrificed pay.

Net pay and relief at source both leave £32,081.40 on £42,000, since each gives tax relief at the basic rate and neither removes National Insurance. That makes them £168 a year behind salary sacrifice at this salary.
