Understanding the Average UK Salary by Age: A Guide for Job Seekers

Understanding the Average UK Salary by Age

When you're negotiating a job offer or planning your career, knowing how your salary compares to others in your age group is a powerful tool. The Office for National Statistics (ONS) publishes detailed earnings data each year through the Annual Survey of Hours and Earnings (ASHE), which breaks down pay by age, region, occupation, and industry. This article explores the latest figures for the average UK salary by age and explains how to use them when evaluating job offers.

Why Age Matters in Salary Data

Earnings typically follow a clear life-cycle pattern. Pay rises quickly during your twenties as you gain experience and qualifications, peaks in your forties, and then gradually declines as some workers reduce hours or move into less demanding roles. Understanding this curve helps you set realistic expectations and spot when an offer is above or below the norm for your age.

ONS ASHE 2025 provisional data shows that the median full-time annual salary across all ages is £39,039. But this headline figure hides significant variation. For all employees (including part-time), the median is £32,890. The median hourly rate for full-time employees is £19.67.

Average UK Salary by Age: The Full Breakdown

The table below, based on ONS ASHE data, shows median annual earnings for employees on adult rates who have been in the same job for at least a year. These figures are the most reliable benchmark for typical pay at each stage of your career.

Age Group	Median Annual Salary
18–21	£13,069
22–29	£29,855
30–39	£36,000
40–49	£37,734
50–59	£34,835
60+	£26,750

Key observations:

• The biggest jump occurs between the 18–21 and 22–29 groups, reflecting the transition from entry-level roles to more experienced positions.
• Earnings continue to rise through the thirties and peak in the 40–49 bracket.
• After age 50, median pay declines, partly due to some workers shifting to part-time or lower-paid roles.

How to Use This Data When Negotiating a Job Offer

When you receive a job offer, compare the proposed salary to the median for your age group. If you're 28 and the offer is £32,000, that's above the £29,855 median for 22–29 year olds – a strong position. If you're 45 and offered £35,000, that's slightly below the £37,734 median for 40–49 year olds, so you may want to negotiate or consider other benefits.

Remember that these are national medians. Your actual market value depends on:

• Region: London salaries are typically 10–20% higher. The South East saw the lowest growth (2.9%) in 2025, while Northern Ireland had the highest (7.4%).
• Industry: Finance, IT, and legal sectors pay above average; retail and hospitality pay below.
• Occupation: Specific roles within an age group can vary widely.

Median vs Mean: Which Should You Use?

The ONS prefers the median because it is less affected by a small number of very high earners. The mean (traditional average) for full-time employees is around £45,800 – significantly higher than the median of £39,039. When comparing job offers, always use the median as your benchmark. The mean can give a misleadingly optimistic picture.

The Impact of the National Living Wage

The National Living Wage (NLW) sets a floor for hourly pay. In April 2025, the rate for workers aged 21 and over was £12.21 per hour. From April 2026, it rises to £12.71. For a full-time worker on 37.5 hours per week, that equates to roughly £24,785 per year. Younger workers have lower minimums: £10.00 for 18–20 year olds and £7.55 for 16–17 year olds. These rates directly influence the lower end of the salary distribution, especially for the 18–21 age group.

Caveats and Considerations

• Provisional data: The 2025 ASHE figures are provisional and may be revised.
• Exclusions: The data excludes self-employed people, the armed forces, and those whose pay was affected by absence.
• Scotland's Income Tax: If you work in Scotland, different Income Tax bands apply, which can affect your take-home pay compared to the rest of the UK. Always factor in tax when comparing offers.
• Job tenure: The age breakdowns are for employees who have been in the same job for at least a year. New hires may earn slightly different amounts.

Conclusion

Knowing the average UK salary by age gives you a solid foundation for career planning and salary negotiation. The ONS ASHE data shows that median earnings rise steadily from around £13,000 for 18–21 year olds to a peak of nearly £38,000 for those in their forties. Use these figures as a starting point, but always adjust for your specific region, industry, and experience level.

Frequently Asked Questions

What is the average UK salary by age?

According to the ONS Annual Survey of Hours and Earnings (ASHE) 2025, median annual earnings for full-time employees are £39,039. Broken down by age, the median for 18–21 year olds is £13,069, rising to £29,855 for ages 22–29, £36,000 for 30–39, peaking at £37,734 for 40–49, then declining to £34,835 for 50–59 and £26,750 for 60+. These figures are for employees on adult rates who have been in the same job for at least a year.

How does the National Living Wage affect salary by age?

The National Living Wage (NLW) sets a legal minimum hourly rate for workers aged 21 and over. In April 2025 it was £12.21 per hour, rising to £12.71 from April 2026. For younger workers, lower minimum wage rates apply: £10.00 for 18–20 year olds and £7.55 for 16–17 year olds. These rates directly influence the lower end of the salary distribution, particularly for younger age groups.

Should I use median or mean salary when comparing job offers?

The ONS recommends using the median as it represents the middle point of the pay distribution and is less skewed by very high or low earners. The mean (traditional average) is higher – around £45,800 for full-time employees – but may not reflect typical pay. When negotiating a job offer, compare the offered salary to the median for your age group and region, and consider industry-specific benchmarks.
