Comparing Hourly Jobs with Salaried Offers: The Minimum Wage Under 21

When you're under 21 and looking for work, understanding how your hourly wage translates into a yearly salary is essential – especially if you're weighing up a part-time job against a full-time salaried position. The UK government sets separate minimum wage rates for different age groups, and these rates change every April. From 1 April 2026, the minimum wage under 21 will increase, making it even more important to know what you should be earning.

What Are the 2026 Minimum Wage Rates for Under 21s?

According to official GOV.UK National Living Wage rates, the following hourly rates apply from April 2026:

• National Living Wage (21 and over): £12.71
• 18-20 Year Old Rate: £10.85
• 16-17 Year Old Rate: £8.00
• Apprentice Rate: £8.00 (for apprentices under 19, or those 19+ in their first year)

These figures come from the Low Pay Commission's recommendations, which the government accepted. The 18-20 rate rises by 8.5% (85p), while the under-18 and apprentice rates both increase by 6.0% (45p). The National Living Wage for those aged 21 and over goes up by 4.1% to £12.71.

Converting Hourly Pay to Annual Salary

To compare a job paying an hourly rate with a salaried role, use the standard conversion: annual salary ≈ hourly rate × hours per week × 52 weeks. This assumes you work every week of the year with paid holiday (statutory minimum is 5.6 weeks, but many employers include this in the 52-week calculation).

Let's look at examples for the minimum wage under 21:

• 18-20 year old at 37.5 hours/week: £10.85 × 37.5 × 52 = £21,157.50 gross per year
• 18-20 year old at 40 hours/week: £10.85 × 40 × 52 = £22,568 gross per year
• Under 18 or apprentice at 37.5 hours/week: £8.00 × 37.5 × 52 = £15,600 gross per year

These figures are gross – before tax and National Insurance. The Personal Allowance for income tax is £12,570, so you'll pay tax on earnings above that. For a full-time 18-20 year old earning £21,157, the taxable amount is about £8,587, resulting in roughly £1,717 in income tax (at 20%) plus National Insurance contributions.

Why the Distinction Matters for Job Seekers

If you're under 21, you might be offered a job that pays the minimum wage under 21 – but be aware that once you turn 21, your employer must pay you the higher National Living Wage. Some employers pay above the minimum, especially in sectors like retail, hospitality, or logistics. Always check your contract for the exact hourly rate and any London weighting or shift premiums.

For those comparing hourly jobs with salaried offers, remember that salaried roles often include benefits like pension contributions, sick pay, and guaranteed hours. Hourly jobs may offer flexibility but can have variable shifts. Use our Hourly to Salary tool to quickly see the annual equivalent of any hourly rate.

Overtime, London Weighting, and Other Factors

The conversion above assumes a standard working week with no overtime. If you work extra hours, your actual annual earnings will be higher – but overtime may be paid at a different rate (often 1.5× or 2×). London weighting is an additional allowance for jobs in Greater London, typically adding £3,000–£5,000 per year, but it's not mandatory for minimum wage roles.

Also note that the minimum wage under 21 applies to employees, not to self-employed contractors or gig workers. If you're on a zero-hours contract, your weekly hours may fluctuate, making annual projections less reliable. Always use your average weekly hours over a representative period.

How the 2026 Increase Affects Take-Home Pay

The GOV.UK analysis of the 2026 minimum wage notes that the increase interacts with the tax and benefit system. For a single person working 35 hours per week at the National Living Wage (21+), the weekly take-home pay rises by about £11.90 (3.3%). For under-21 workers, the percentage increase may be larger because the 18-20 rate rises by 8.5%. However, frozen tax thresholds mean that some workers will see a slightly smaller net gain as they move into tax-paying brackets.

If you receive Universal Credit, the increase in the standard allowance (6.2%) may boost your household income more than the wage rise alone. For detailed calculations, refer to the salary data page or use our hourly calculator to model your own situation.

Practical Tips for Under-21 Job Hunters

• Know your age band: If you're 20, you're entitled to £10.85 from April 2026. If you're 21, you jump to £12.71.
• Check your apprenticeship status: If you're an apprentice over 19 and past your first year, you must be paid at least the age-based rate.
• Ask about progression: Some employers offer pay rises as you gain experience or turn 21. Discuss this at interview.
• Compare total compensation: A salaried job might include pension, health insurance, or training opportunities that an hourly role doesn't.

Summary

The minimum wage under 21 for 2026/27 is £10.85 for 18-20 year olds and £8.00 for under-18s and apprentices. Converting these hourly rates to annual salary gives you a baseline for comparing job offers. Remember that actual earnings depend on hours, overtime, location, and benefits. Always use official sources like GOV.UK and ONS ASHE to verify current rates, and consult your contract for exact terms.
