Minimum Wage 18 UK: What 18–20 Year Olds Actually Earn After Tax in 2026/27

Minimum Wage 18 UK: What You Actually Take Home

Many people assume the minimum wage is a single rate for everyone, but in the UK it varies by age. For 18–20 year olds, the National Minimum Wage (NMW) from April 2026 is £10.85 per hour – a significant increase from £10.00 in the previous year. This article explains what that means for your take-home pay, busts common myths, and helps you understand the difference between gross and net earnings.

The 2026/27 Minimum Wage Rates for Different Ages

GOV.UK sets out four main minimum wage bands:

• National Living Wage (21 and over): £12.71 per hour
• 18–20 year olds: £10.85 per hour
• Under 18: £8.00 per hour
• Apprentice: £8.00 per hour (for apprentices under 19, or 19+ in first year)

If you are 18, 19, or 20, your employer must pay you at least £10.85 for each hour worked. Once you turn 21, you become entitled to the higher National Living Wage. This age-based system often catches people out – especially younger workers who expect the same rate as older colleagues.

Gross Salary vs Take-Home Pay: A Worked Example

Let’s take a typical full-time week of 37.5 hours (common in many retail and hospitality jobs). At £10.85/hour, your annual gross salary is:

£10.85 × 37.5 × 52 = £21,157.50

From this gross amount, the government deducts:

• Income Tax: You have a Personal Allowance of £12,570 (tax-free). The remaining £8,587.50 is taxed at 20%, giving £1,717.50 in tax.
• National Insurance: You pay 8% on earnings above the primary threshold of £12,570. That’s 8% of £8,587.50 = £687.

So your take-home pay is:

£21,157.50 – £1,717.50 – £687 = £18,753 per year

That works out at £1,562.75 per month (or about £360 per week).

If you work 40 hours a week, gross rises to £22,568, tax to £2,000, NI to £800, and take-home to £19,768 per year.

Common Myths About the Minimum Wage for 18-Year-Olds

Myth 1: “The minimum wage is the same for everyone.” As shown above, it’s not. Age matters. An 18-year-old can legally be paid £1.86 less per hour than a 21-year-old. Many young workers don’t realise they should get a pay rise when they turn 21.

Myth 2: “Take-home pay is almost the same as gross.” Because the Personal Allowance covers a large chunk of earnings, the effective tax rate on minimum wage is low – around 11% overall. But you still lose over £2,400 a year to tax and NI. Always check your payslip.

Myth 3: “You don’t pay National Insurance if you’re under 21.” National Insurance (NI) starts once your earnings exceed £12,570 per year, regardless of age. So if you work full time on the 18–20 rate, you will pay NI. Only those earning below £12,570 (e.g., part-time workers) escape NI.

Myth 4: “Student loans don’t apply at this income.” Most undergraduate loan plans have thresholds above £21,157, so no repayments. But if you have a Postgraduate Loan (threshold £21,000), you would repay a tiny amount – about £9 per year. Always check your loan type.

Scotland vs Rest of UK: A Small Difference

Scotland uses different income tax bands. For someone earning £21,157, the first £3,967 of taxable income is taxed at 19% (starter rate) instead of 20%. This saves about £40 per year compared to England, Wales, and Northern Ireland. So take-home in Scotland is roughly £18,793 per year instead of £18,753. The difference is small but worth noting if you live in Scotland.

Pension Contributions and Auto-Enrolment

Auto-enrolment applies to workers aged 22 and over who earn more than £10,000. Most 18-year-olds are under 22, so they are not automatically enrolled. However, you can choose to join a workplace pension. If you do, a typical 5% contribution on qualifying earnings would reduce your take-home by about £80–£100 per month. Many young workers opt out, but that means missing out on employer contributions.

How to Check Your Pay

If you’re 18 and working, compare your hourly rate to the official NMW. Your payslip should show your gross pay, tax, NI, and any other deductions. Use the take-home calculator on After Tax Salary to see exactly what you’ll get after all deductions.

Summary

The minimum wage for 18-year-olds in the UK in 2026/27 is £10.85 per hour. Full-time take-home pay is about £1,563 per month after tax and NI. Remember that this rate only applies until you turn 21, when you become eligible for the higher National Living Wage. Always check your age band and don’t assume your employer is paying you correctly – use official GOV.UK guidance to verify.

Frequently Asked Questions

Is the minimum wage the same for 18-year-olds as for older workers?

No. In the UK, the minimum wage depends on age. From April 2026, the National Living Wage for workers aged 21 and over is £12.71 per hour. For 18–20 year olds, the National Minimum Wage is £10.85 per hour. Under-18s and apprentices have a lower rate of £8.00 per hour. So an 18-year-old legally earns less per hour than a 21-year-old doing the same job, unless the employer chooses to pay more.

How much take-home pay does an 18-year-old on minimum wage get after tax?

For a full-time 18-year-old working 37.5 hours per week at £10.85/hour, annual gross pay is £21,157.50. After deducting income tax (£1,717.50) and National Insurance (£687), the annual take-home pay is approximately £18,753, which is about £1,563 per month. If you work fewer hours, your take-home will be lower, and you may pay no tax if your total earnings stay below the personal allowance of £12,570.

Do 18-year-olds on minimum wage have to pay student loan repayments?

It depends on the loan plan. Most undergraduate loan plans (Plan 1, 2, 4, 5) have repayment thresholds above £21,157.50, so no repayments are required. However, if you have a Postgraduate Loan, the threshold is £21,000, meaning you would repay 6% of earnings above that – about £9.45 per year on the full-time minimum wage. Always check your specific loan type and your payslip.
