The Gender Pension Gap Explained

If you're a woman looking at your pension statement and wondering why the total feels smaller than you expected, you are very far from alone. Across the UK, women reach retirement with meaningfully smaller pension pots than men, on average, and the gap between them is larger, in percentage terms, than the much more widely discussed gender pay gap. This page explains what the gender pension gap actually is, why it happens, and what you can do, individually, to help narrow it for yourself, while being clear that the underlying causes are structural rather than anything to do with how carefully any one woman has managed her money.

What is the gender pension gap?

The gender pension gap is the difference between the average pension wealth or retirement income of men and women. Various studies calculate it slightly differently, some looking at private pension pot size at retirement, others at annual retirement income once pensions are in payment, but the consistent finding across almost all of them is that women retire with substantially less pension wealth than men, often estimated at somewhere between one third and one half less, depending on the measure used and the age group studied. Because pension income tends to be one of the largest components of retirement income for anyone who was not a homeowner outright or did not have significant other savings, a smaller pension pot translates fairly directly into a lower standard of living in retirement.

It's worth being precise about the difference between the gender pay gap and the gender pension gap, because they are related but not the same thing. The pay gap measures the difference in hourly or annual earnings between men and women while they are working. The pension gap measures the difference in the pension wealth that has actually built up by the time someone retires. Because pension saving compounds over decades, and because the pay gap is only one of several contributing factors, the pension gap tends to come out considerably wider than the pay gap when both are expressed as a percentage. A relatively modest difference in pay, repeated and compounded over a 30 or 40 year working life, and combined with other factors like career breaks and part-time work, can snowball into a much larger difference in the pension pot at the end.

Why the pension gap ends up so much wider than the pay gap

Pension saving is not just about the rate of pay at any one moment; it is about the accumulated effect of contributions, investment growth, and the number of years spent contributing at all. This means the pension gap tends to be the product of several gaps stacking on top of each other, rather than a single cause. Even a woman earning identical hourly pay to a male colleague throughout her career can end up with a noticeably smaller pension pot if she has taken time out of paid work, worked reduced hours for a period, or started pension saving later than he did. Each of these factors, individually, might look like a fairly small difference year to year, but pension saving is a long game, and small differences compounded over decades, with investment growth applied to a smaller base each year, add up to a much larger absolute gap by the time retirement arrives.

The main drivers of the gender pension gap

Career breaks for childcare, disproportionately taken by women, are one of the single biggest contributors. When someone steps out of paid work, whether for a few months of maternity leave or several years raising children, both their own and their employer's pension contributions typically pause or reduce for that period, even where valuable protections (discussed on our page about career breaks) soften the impact on state pension entitlement. Because women still take the substantial majority of extended childcare-related career breaks in the UK, this factor alone accounts for a significant share of the overall gap.

More part-time work is a closely related driver. Many women move to part-time hours at some stage in their working life, often to balance paid work with caring responsibilities, and part-time earnings usually mean smaller pension contributions in absolute pounds, even where the contribution rate itself is unchanged. Part-time work can also, in some cases, mean falling below the earnings threshold for automatic enrolment altogether, meaning no workplace pension contributions are being made at all for that job, which we explain in more detail below.

The gender pay gap itself is a third driver, feeding through into smaller pension contributions even for women in full-time, continuous employment. Because most workplace pension contributions are calculated as a percentage of pay, any gap in hourly or annual earnings between men and women translates directly into a gap in the pounds and pence actually going into each person's pension pot, even before any career break or reduced-hours effect is added on top.

Finally, women living longer on average than men means retirement savings need to stretch further for the typical woman, even where the pot itself is the same size. Someone who can expect to live, on average, several years longer in retirement needs either a larger pot or a lower annual drawdown rate to make that pot last, all else being equal. This longevity effect does not reduce the size of anyone's pension pot, but it does mean the same pot size supports a lower standard of living for a woman who lives longer than the average man, which is a further, less visible dimension to the overall gap in retirement outcomes.

How auto-enrolment thresholds can inadvertently disadvantage part-time and lower earners

Automatic enrolment into a workplace pension only applies to employees earning above a minimum earnings threshold, currently £10,000 a year, in any single job. Someone working part-time, or juggling more than one part-time role, can easily fall below that threshold in each individual job even if their combined earnings across two or three jobs would comfortably clear it, meaning they may not be automatically enrolled anywhere and could miss out on employer pension contributions altogether unless they proactively ask to opt in. Because women make up the large majority of part-time workers in the UK, this threshold effect disproportionately affects women, and is one of the more technical but genuinely impactful contributors to the wider gender pension gap. Our page on auto-enrolment for part-time workers explains the threshold rules in detail and what you can do if you think you might be affected.

The average gap by life stage

The size of the gender pension gap is not static across a working life; it tends to widen at each stage where career breaks, part-time work, or pay differences accumulate. The table below illustrates, in broad and necessarily approximate terms, how the average gap tends to widen through a typical career.

Does the state pension have a gender gap too?

It's a fair question, because the new state pension, introduced in 2016, is designed to be gender-neutral in its rules: everyone needs the same number of qualifying National Insurance years, currently 35 for a full amount, and the same weekly rate applies regardless of gender, currently £230.25 a week for someone with a full record. In principle, then, the state pension should not itself create a gap. In practice, though, women are statistically more likely to have gaps in their National Insurance record from years spent caring for children or relatives without always having credits applied correctly, and more likely to have spent time working below the National Insurance lower earnings limit in a part-time job, so average state pension outcomes for women can still lag men's, even though the underlying rules are the same for everyone. This is one reason it is worth checking your own National Insurance record directly rather than assuming a gender-neutral rulebook automatically produces a gender-neutral outcome for you personally.

What is being done to close the gap

The gender pension gap has received increasing policy attention in recent years, and several changes are aimed, at least in part, at narrowing it over time. Shared parental leave rules, though still under-used by many families, are designed to make it easier for both parents to share time out of work around the arrival of a child, rather than the burden falling on one parent by default. There has also been sustained debate about lowering or removing the lower earnings threshold for automatic enrolment, and about whether contributions should be calculated from the first pound earned rather than only on qualifying earnings above £6,240, both of which would disproportionately benefit part-time workers, most of whom are women. Some employers have also gone beyond the legal minimum unilaterally, for example by continuing full pension contributions throughout unpaid periods of parental leave, or by offering more generous non-contributory top-ups aimed specifically at reducing the pension gap within their own workforce. None of these changes are complete solutions on their own, but taken together they represent a slow, ongoing shift in how the pension system accounts for patterns of work and caring that have historically been more common among women.

A few other angles worth considering

Divorce and separation can significantly affect the pension gap picture for an individual woman, in both directions. Pensions built up during a marriage can, in England and Wales, be shared or offset as part of a divorce settlement, which can meaningfully improve the position of a lower-earning spouse, but this only happens where it is actively requested and agreed as part of the settlement, so it is not automatic. Anyone going through separation should treat pensions as seriously as property or savings when working out what a fair settlement looks like, rather than overlooking them because they feel abstract or far in the future.

Investment choices within a pension can also make a difference over the long run, though this is a more individual and technical area than the structural drivers discussed above. Because many people are automatically placed into a default investment fund when they are enrolled into a workplace pension, it is worth periodically checking that the fund and risk level still suit your circumstances and time horizon, particularly if a career break has changed your expected retirement date or your appetite for investment risk.

Practical steps that can help narrow the gap for you personally

While the causes of the gender pension gap are structural, there are still practical, individual steps that can help narrow its effect on your own retirement outcome. Understanding exactly what you are entitled to is the first step: request pension statements from every scheme you have ever contributed to, including old workplace schemes from previous employers, and get a state pension forecast so you know both pieces of the picture rather than just one.

If you are not currently earning, or earning very little, you can still make personal pension contributions and receive tax relief. A non-earner can contribute up to £2,880 net each year into a personal pension and have it topped up automatically to £3,600 with basic rate tax relief added by the scheme, even with no earnings at all. This is a genuinely valuable and often underused way to keep a pension ticking over during a career break; our page on pension tax relief for non-taxpayers explains exactly how this works and how to set it up.

It is also worth checking your National Insurance record for any gaps arising from years spent caring for children or relatives. Certain caring roles attract National Insurance credits that protect your state pension entitlement even without paid work or contributions, but these credits are not always applied automatically in every circumstance, so it is worth checking your record periodically to make sure the years you expect to be covered actually show as such.

If you have taken a career break and later returned to higher earnings, it is also worth looking into carry forward rules, which in some circumstances allow you to use unused annual allowance from the previous three tax years, potentially letting you make a larger catch-up pension contribution in a year when you can afford it, subject to the usual annual allowance limit of £60,000. This will not be relevant to everyone, but for anyone who has had a lower-earning period followed by a higher-earning one, it is worth checking whether it applies to you.

Finally, if you are married or in a civil partnership, it is worth having a frank conversation with your partner about pension saving as a shared household matter rather than a purely individual one, particularly if one of you has stepped back from paid work or reduced hours to support the family. A spouse or partner can make contributions into a personal pension on behalf of a partner who is not earning, which is one practical way a household can actively work to narrow the gender pension gap between two partners rather than leaving it to develop by default.

Common questions about the gender pension gap

Is the gender pension gap the same everywhere in the UK? Broadly, the same structural drivers, career breaks, part-time work, and the pay gap, apply across England, Scotland, Wales and Northern Ireland, though state pension rules are UK-wide while some benefits and support services are administered separately in each nation.

Does the gap affect self-employed women differently? Self-employed workers of any gender sit outside automatic enrolment entirely, since there is no employer to enrol them, which means self-employed women need to be particularly proactive about setting up and maintaining their own pension saving, without the default nudge that automatic enrolment provides to employees.

Can the gap be closed for an individual, or only for society as a whole? Both matter. Society-wide policy change, such as adjusting auto-enrolment thresholds or encouraging shared parental leave, works on the average outcome across the whole population, while the practical, individual steps described above can meaningfully improve any one woman's personal position within that wider picture, even before any policy change arrives.

A structural issue, not a personal failing

It bears repeating clearly: the gender pension gap is the product of decades of structural factors in how caring responsibilities, part-time work, and pay have been distributed between men and women, not a reflection of any individual woman's financial choices or discipline. If your own pension pot looks smaller than you would like, that is worth understanding and, where possible, addressing with the practical steps above, but it is not evidence that you have done anything wrong. Recognising the structural nature of the gap is often the first step towards approaching your own retirement planning with less self-blame and more constructive, practical action.
