Women in the UK are on track to lose out on more than £93,000 in earnings over a 40-year career because of the gender pay gap, new analysis reveals.
Research by Instant Offices shows how inequalities between men and women in the workplace compound over time, leaving women with a significant lifetime shortfall that directly impacts pensions, savings and long-term financial security.
The average UK salary for full-time employees was £37,430 in 2024, up £2,467 on the previous year. Graduate starting salaries in 2025 are expected to average £31,000, though they vary widely depending on industry and region.
Salaries typically climb with age, peaking in the 40–49 bracket. The most striking jump comes when workers move from their 20s into their 30s, with average earnings rising by £7,696 in a single year.
Yet even at entry level, a gap exists. Men aged 18–21 earn on average £520 more per year than women. By the time employees reach their 40s, this disparity has grown to almost £3,000 annually — despite this being the peak earning decade for both genders.
The UK’s average gender pay gap stands at 9%, but it grows steadily throughout a career.
- Men in their 30s earn £1,664 more per year than women on average.
- By their 40s, the gap has widened to £2,756 annually.
- In their 50s, women earn £3,484 less than male peers each year.
Over four decades, these small yearly gaps accumulate into a £93,392 lifetime shortfall. And that figure doesn’t even account for the knock-on effect of lower pension contributions, bonuses or investment opportunities. Factoring those in, the true cost likely exceeds £100,000.
| Age range | Men’s average pay | Women’s average pay | Annual gap | Gap over bracket | Cumulative gap |
|---|---|---|---|---|---|
| 18–21 | £24,960 | £24,440 | £520 | £2,080 | £2,080 |
| 22–29 | £33,176 | £32,292 | £884 | £7,072 | £9,152 |
| 30–39 | £41,652 | £39,988 | £1,664 | £16,640 | £25,792 |
| 40–49 | £45,552 | £42,796 | £2,756 | £27,560 | £53,352 |
| 50–59 | £43,940 | £40,456 | £3,484 | £34,840 | £88,192 |
| 60–61 | £38,636 | £36,036 | £2,600 | £5,200 | £93,392 |
The gender pay gap is not just a “moment-in-time” inequality. It shapes a woman’s entire financial trajectory, leading to reduced pension pots, less disposable income for investments, and greater vulnerability to financial shocks.
It also has wider economic consequences, reducing the total spending power and productivity of half the workforce.
Experts say meaningful change requires employers to act. Strategies include:
- Conducting regular pay audits to ensure parity across roles.
- Introducing transparent salary bands, so employees can see how they can progress.
- Supporting career progression for women, through mentorship and fair promotion practices.
- Offering flexible working and parental leave, helping women to balance career and caregiving responsibilities.
- Monitoring recruitment and promotion practices to reduce bias.
- Investing in professional development equally across genders.
While women can and should advocate for their worth, the onus is on employers to fix systemic imbalances. Without change, millions of women will continue to face a career-long financial penalty simply for being female.
As the analysis makes clear, tackling the gender pay gap is not just about fairness today — it’s about ensuring equality of opportunity, wealth and security over a lifetime.
