Minimum Wage for 18: How Much You Actually Take Home in 2026/27

Understanding the Minimum Wage for 18-Year-Olds in 2026/27

If you’re 18 and starting work, or you employ someone that age, the first thing to know is the legal minimum hourly rate. From April 2026, the National Minimum Wage (NMW) for 18 to 20 year olds is £10.85 per hour – up from £10.00 the year before. This is set by the government and applies across the UK, including Scotland, Wales and Northern Ireland.

But the hourly rate is only part of the story. What you actually get in your bank account – your take-home pay – depends on how many hours you work, your tax code, National Insurance, and any pension or student loan deductions. This article explains how it all works for someone on the minimum wage for 18.

Gross Pay: What You Earn Before Deductions

Let’s start with the gross annual salary. A typical full-time week is 37.5 hours (though some contracts are 35 or 40 hours). At £10.85 per hour, 37.5 hours a week for 52 weeks gives:

• Weekly gross: £10.85 × 37.5 = £406.88
• Monthly gross: £406.88 × 52 / 12 = £1,763 (approx)
• Annual gross: £10.85 × 37.5 × 52 = £21,157.50

If you work 40 hours a week, the annual gross rises to about £22,568. But for this article we’ll stick with the 37.5-hour standard used by many employers and by the After Tax Salary calculator.

Income Tax and National Insurance: The Main Deductions

Everyone in the UK has a Personal Allowance of £12,570 in 2026/27 – that’s the amount you can earn before paying any Income Tax. On £21,158 gross, your taxable income is:

£21,158 – £12,570 = £8,588

You pay 20% Income Tax on that slice: £1,717.60 per year.

National Insurance (employee Class 1) is charged at 8% on earnings above the same £12,570 threshold. So that’s another 8% of £8,588 = £687.04 per year.

Total deductions for tax and NI: £1,717.60 + £687.04 = £2,404.64.

That leaves take-home pay of:

£21,158 – £2,404.64 = £18,753.36 per year

Monthly take-home: £18,753.36 ÷ 12 = £1,562.78

These figures match the estimates from and wagecheck.co.uk. The effective tax rate on gross pay is about 11.4% – lower than many people expect because the first £12,570 is tax-free.

Scotland: Slightly Different Income Tax

If you live in Scotland, the Income Tax bands are different. For 2026/27, the starter rate is 19% on the first £3,967 of taxable income, then 20% on the next slice up to £31,092. On £8,588 of taxable income, a Scottish worker pays:

• 19% on £3,967 = £753.73
• 20% on remaining £4,621 = £924.20
• Total tax = £1,677.93

That’s about £40 less than the rest of the UK. So monthly take-home in Scotland is roughly £1,566 – a small but noticeable difference.

What About Pensions and Student Loans?

Many workers are automatically enrolled into a workplace pension. The minimum employee contribution is 5% of qualifying earnings (typically earnings above £6,240). For someone on £21,158, that means about £746 per year going into the pension, reducing take-home pay by roughly £62 per month. Some employers offer more, and you can opt out if you prefer.

Student loans – most plans don’t bite at this salary. Plan 1 threshold is £26,900, Plan 2 is £29,385, Plan 4 (Scotland) is £33,795. Only Plan 5 (introduced for new students from 2023) has a £25,000 threshold, so if you’re on Plan 5 and work 40 hours a week (gross £22,568), you’d repay 9% on the £2,568 above £25,000 – about £231 per year. At 37.5 hours, you’re below the threshold and pay nothing.

Comparing with Other Minimum Wage Rates

It’s useful to see how the minimum wage for 18 compares with other age groups:

• 21 and over (National Living Wage): £12.71/hr → £24,785 gross → ~£21,364 take-home
• 18–20: £10.85/hr → £21,158 gross → ~£18,753 take-home
• Under 18 / Apprentice: £8.00/hr → £15,600 gross → ~£14,190 take-home

Under-18s don’t pay National Insurance until they turn 16 (and even then only if earnings exceed £12,570), so their take-home is proportionally higher.

How to Calculate Your Own Take-Home Pay

Your actual take-home will depend on your exact hours, tax code, and any other deductions. The best way to get a precise figure is to use a take-home calculator that uses the latest 2026/27 rates. You can also check your payslip – your employer must show gross pay, tax, NI, and any other deductions.

Remember: the minimum wage is a floor, not a ceiling. Many employers pay more, especially for skilled roles or in areas with higher living costs. The salary data on this site can help you see typical pay for different jobs and regions.
