iHow it is calculated
From your gross salary two things are taken: Income Tax and National Insurance. Income tax is charged on income above the Personal Allowance (£12,570) — 20% to £50,270, 40% to £125,140, 45% above. National Insurance is 8% between £12,570 and £50,270, then 2%. Above £100,000 the Personal Allowance tapers away (£1 lost per £2), creating an effective ~60% band up to £125,140. Optional student loan and pension deductions can also apply.
take-home = gross − Income Tax − National Insurance − student loan − pension
Example — £45,000 gross (2026/27, England): Personal Allowance £12,570, taxable £32,430 → income tax £6,486, employee NI £2,594 → net £35,920 a year (£2,993/month, £691/week).
