Minimum Wage for 18 Year Old in 2025: Gross Pay, Tax and Take-Home Explained

Minimum Wage for 18 Year Old in 2025: What You’ll Actually Earn

If you’re 18 and starting work in 2025, the minimum wage for 18 year old 2025 is £10.00 per hour. This rate applies to all workers aged 18 to 20 and comes into effect from 1 April 2025. It’s a substantial rise from the previous £8.60, reflecting the Government’s commitment to boosting pay for younger workers.

But knowing your hourly rate is only half the story. What really matters is how much lands in your bank account after tax, National Insurance, and other deductions. This guide breaks down gross pay, take-home pay, and the key factors that affect your net income.

Gross Annual Pay on the 2025 Minimum Wage

Let’s assume you work full-time – say 37.5 hours per week (common in retail, hospitality, and many entry-level jobs). At £10.00 per hour:

• Weekly gross pay: 37.5 × £10.00 = £375.00
• Annual gross pay (52 weeks): £375 × 52 = £19,500

If you work fewer hours, your gross pay will be proportionally lower. Part-time workers on, say, 20 hours per week would earn about £10,400 a year.

Income Tax: How Much You’ll Pay

For the 2025/26 tax year, the standard Personal Allowance is £12,570. This means you don’t pay any Income Tax on the first £12,570 you earn. On earnings above that, you pay 20% (basic rate) up to £37,700.

On £19,500:

• Taxable income: £19,500 – £12,570 = £6,930
• Income Tax: 20% of £6,930 = £1,386 per year

If you live in Scotland, the tax bands are different. On £19,500, you’d pay:

• 19% on the first £2,827 (starter rate)
• 20% on the next £12,094 (basic rate, up to £14,921)
• 21% on the remaining £4,579 (intermediate rate, up to £31,092)

That works out to roughly £1,270 in Scottish Income Tax – slightly less than in England.

National Insurance (NI)

Employee National Insurance is deducted from your pay once you earn above the primary threshold of £242 per week (for 2025/26). You pay:

• 8% on earnings between £242 and £967 per week
• 2% on anything above £967 per week

For weekly earnings of £375:

• NI due on £375 – £242 = £133
• NI: 8% × £133 = £10.64 per week
• Annual NI: £10.64 × 52 = £553

No higher-rate NI applies here because you’re well below the upper earnings limit.

Estimated Take-Home Pay

Putting it together for a full-time 18-year-old on minimum wage:

Item	Annual	Monthly (approx.)
Gross pay	£19,500	£1,625
Income Tax	–£1,386	–£115.50
National Insurance	–£553	–£46.08
Take-home pay	£17,561	£1,463

This is before any pension contributions or student loan repayments. If you’re enrolled in a workplace pension (auto-enrolment), you’ll typically contribute 5% of your qualifying earnings, which reduces your take-home further but also lowers your tax and NI slightly.

What About Student Loans?

If you have a student loan (Plan 1, 2, 4, or Postgraduate), repayments kick in once your earnings exceed the relevant threshold. For example:

• Plan 2 threshold: £28,470 per year – so no repayment on £19,500.
• Postgraduate Loan threshold: £21,000 – again, no repayment.

Most 18-year-olds starting work won’t yet have student loans, but if you do, check the thresholds on.

How the 2025 Rate Compares to Other Ages

It’s worth noting that the National Living Wage for workers aged 21 and over is £12.21 per hour in 2025. That’s a significant jump. If you turn 21 during the year, your employer must raise your pay to the higher rate. The Government has also announced that from April 2026, the 18–20 rate will rise to £10.85 per hour.

The hourly minimum wage rate is the same across the UK. However, Scottish residents pay Income Tax under different bands.
