A gross salary of £20,000 in 2026/27 in England, Wales or Northern Ireland leaves a take-home of £17,920 a year — about £1,493 a month or £345 a week. Income tax of £1,486 and employee National Insurance of £594 are deducted via PAYE. Of that, £7,430 is taxed at the 20% basic rate (after the £12,570 Personal Allowance).
The full breakdown for England, Wales and Northern Ireland
| Component | Annual | Monthly |
|---|---|---|
| Gross salary | £20,000 | £1,667 |
| Personal allowance applied | £12,570 | £1,048 |
| Income tax | −£1,486 | −£124 |
| Employee National Insurance | −£594 | −£50 |
| Take-home | £17,920 | £1,493 |
Only £7,430 of this salary is taxed at all, so tax and NI come to 10.4% and about 90p of each pound reaches you.
The Scottish version is different
A £20,000 salary never reaches Scotland's 21% intermediate band, so the only difference is the 19% starter rate on the first £3,967 of taxable pay — £39.67 a year in Scotland's favour.

Why £20,000 is the first proper salary cliff
£20,000 is the first salary level where take-home growth feels noticeably slower than gross growth. Every additional pound above £12,570 has 28p taken in income tax (20%) + employee National Insurance (8%). The £1,000 Personal Savings Allowance still applies in full, so savings interest up to £1,000 a year is tax-free.
Two things to consider at this level:
- Marriage Allowance — if your partner earns under £12,570, they can transfer £1,260 of Personal Allowance to you, saving up to £252 in income tax. See the Marriage Allowance checker.
- Workplace pension — auto-enrolment at the standard 5% employee + 3% employer rate gives 20% income tax relief at source via salary sacrifice or net pay. The £1 you sacrifice becomes about 72p of take-home foregone for a £1 pension contribution.
Student loan repayments do not start at this salary on any plan — the section below sets out the thresholds, and the student loan calculator shows what happens as your pay rises.
Is £20,000 still a full-time wage?
Not at standard full-time hours, and that is new. The National Living Wage for workers aged 21 and over is £12.71 an hour from 1 April 2026. A 37.5-hour week at that rate pays £24,784.50 a year; even a 35-hour week pays £23,132.20. Both are well clear of £20,000. Turn it around and £20,000 buys 30.3 hours a week at the legal floor — £20,000 divided by £12.71 × 52 weeks is 30.26 hours.
The exception is age. The 18-to-20 rate is £10.85 an hour, so a 35-hour week for an 18-year-old pays £19,747 a year and £20,000 is a perfectly lawful full-time wage at that age. For anyone 21 or over on a standard week, it is not — a full-time contract paying £20,000 for 37.5 hours would be an underpayment worth raising.
ONS data says the same thing from the other direction. In the Annual Survey of Hours and Earnings 2025, published on 23 October 2025, £20,000 sits below the 10th percentile of full-time employee jobs, which was £23,990. Fewer than one full-time job in ten pays this little. Against part-time jobs the same number is around the 70th percentile (£20,029).
So if you have typed this figure because it is what your contract says, the question worth asking is usually about hours, not tax. This is part-time pay, part-year pay, or a rate that the statutory floor has now overtaken. Every rung above this one is a full-time salary; this is the last one where the wage floor gets there first.
Where does £20,000 sit in the UK earnings distribution?
Three answers, all correct, depending on which population you measure against — which is why "average salary" comparisons are so useless at this level.
- All employee jobs. Across the 24,897,000 employee jobs in ASHE 2025 Table 1, £20,000 is roughly the 22nd percentile: the 20th percentile was £18,560 and the 25th £22,060.
- Full-time jobs only. Across the 18,154,000 full-time jobs it falls below the 10th percentile of £23,990.
- Part-time jobs only. Across the 6,743,000 part-time jobs, where the median is £14,713, it is close to the 70th percentile of £20,029.
- Taxpayers rather than jobs. HMRC's Survey of Personal Incomes, Table 3.1a, puts £20,000 at the 23rd percentile of total income before tax for 2023-24.
The occupational figures make the point more bluntly. The lowest full-time medians for large occupations in ASHE 2025 Table 14 include care workers at £27,468, stock control clerks at £29,991 across 58,000 jobs and chefs at £30,010 across 107,000 jobs. That is £10,000 clear of this salary, in the occupations that sit at the bottom of the full-time range.
The honest summary: £20,000 is a well-paid part-time job and a poorly-paid full-time one. If it is your term-time, shift or second-earner income, you are in the top third of that population. If it is meant to be a full-time salary, you are in the bottom tenth.
Do student loan repayments start at £20,000?
No — and this is the only salary on this ladder where that is true of every plan at once. The gov.uk thresholds are Plan 1 £26,900, Plan 2 £29,385, Plan 4 £33,795, Plan 5 £25,000 and Postgraduate Loan £21,000. £20,000 is below all five, including the lowest. Hold a Plan 2 and a postgraduate loan together and the deduction is still £0.
It does not stay that way for long. The postgraduate loan bites first, at 6% of everything above £21,000 — so a rise to £22,000 costs £60 a year. Plan 5 follows at £25,000, at 9%, so £26,000 repays £90. By the £25,000 rung a postgraduate borrower is already paying £240 a year, and Plan 5 is sitting exactly on its threshold.
Two practical points while you are under the thresholds. Repayments are calculated per pay period rather than per year, so a bonus or a heavy overtime month can trigger a deduction even though your annual pay never reaches £21,000; you can reclaim it from the Student Loans Company once the tax year has ended. And interest still accrues on the balance while you repay nothing — gov.uk currently shows 4.1% on Plans 1, 4 and 5 and 6% on a Postgraduate Loan. A £0 repayment is not a frozen balance.
What this calculation does not include
The £17,920 above is salary in, salary out. Five things sit outside it, and at £20,000 each behaves differently from how it behaves further up the ladder.
- Pension contributions. The standard 5% employee slice is £1,000 a year on this salary, and relief comes at the basic rate only: 20%, or £200. Under a net pay or relief-at-source scheme that £1,000 costs you £800 of take-home; run through salary sacrifice the 8% NI goes too, so it costs £720. Watch the base, though — many schemes calculate the 5% on qualifying earnings rather than full pay, which at £20,000 is a much smaller number than £1,000. The salary sacrifice calculator takes both.
- Student loan repayments. Nothing at this salary, on any plan or combination of plans — the lowest threshold is the £21,000 Postgraduate Loan. That makes £20,000 the only rung here where the student loan calculator returns zero for a Plan 2 plus postgraduate borrower. The first £1,000 of pay rise starts a 6% postgraduate deduction on the part above £21,000; Plan 4 and the rest stay silent until much higher up.
- Bonuses, overtime and one-off payments. Your marginal rate from £20,000 is 28% — 20% income tax plus 8% NI — and it stays 28% until £50,270, so there is £30,270 of headroom before higher rate becomes a risk. A £1,000 bonus leaves you £720; £5,000 of overtime across the year leaves £3,600. The distortion here is timing, not rate: PAYE spreads your allowance evenly across 12 months, so a lump sum in one payslip is over-taxed that month and corrected later. The bonus and pay-rise calculator shows the true annual position.
- Benefits in kind. Only £7,430 of your pay is being taxed at all, but a benefit in kind is stacked on top of it and taxed at 20% from the first pound — a benefit worth £600 costs £120 in income tax, collected by cutting your tax code rather than billing you. Employee NI is not charged on most benefits in kind (your employer pays Class 1A instead), so a benefit is taxed at 20% where salary is taxed at 28%. Nothing offered at this salary is large enough to push you towards the higher-rate band.
- Multiple jobs. A £20,000 job already uses your entire £12,570 Personal Allowance, so a BR code on a second job — 20% on every pound, no allowance — is usually correct rather than an error to challenge. National Insurance is the interesting part: it is worked out separately for each employment against the same £12,570 threshold, so a small second job can pay no employee NI at all while still paying 20% tax. Second-job income can therefore cost you less at the margin than overtime in the main job.
