Pension on a £40,000 salary — comfortable middle income.

£40,000 is comfortable middle income — well above the UK median but still within basic rate territory. Your annual income tax is around £5,486 and employee NI is around £2,194, leaving roughly £32,320 take-home. You're £10,270 below the higher rate threshold. The most actionable insight at this salary is that you have substantial scope to increase pension contributions without crossing into higher rate brackets where additional relief becomes available. A 12% personal contribution puts £4,800/year into your pension and costs you roughly £3,800 after basic rate relief — 30 years of that compounds to around £335,000 at 5% net growth. That single decision — going from 5% auto-enrolment minimum to 12% personal — produces an extra £150,000+ at retirement compared to the default.
