Retirement Mistake
Missed contributions and investment growth can compound over decades, though outcomes vary by individual circumstances. This is an AI-Generated Image

A five-year career break could leave a 30-year-old worker with nearly £244,000 less in projected pension wealth by retirement after returning to work three days a week, according to new calculations. For higher earners, the projected gap could exceed £422,000 when missed contributions and potential investment growth are taken into account.

For parents who step away from work to provide unpaid care, the financial impact can continue long after they return to employment. Pension contributions may fall or stop altogether, while money that could have remained invested loses years of potential growth.

Stephanie Whitelock, 46, knows that cost first-hand. The Surrey mother left her part-time job at a sixth-form college to care for her 10-year-old son Gabe, who was born with cerebral palsy and autism and uses a wheelchair. She now provides more than 70 hours of unpaid care each week and says there is little left from the roughly £1,000 a month in benefits she receives to put towards her own retirement.

A Career Break Can Have a Long-Term Cost

The calculations show how missed pension contributions can accumulate over decades. For an average earner aged 30 with a salary of £39,500, taking five years away from work and then returning for three days a week could result in about £91,312 in missed pension contributions over the following 35 years.

When potential investment growth is included, the projected reduction in pension wealth reaches £243,950. For a higher earner aged 30 earning £68,400, the corresponding projected difference rises to £422,495. These figures are projections rather than guaranteed losses. The actual outcome would depend on earnings, contribution rates, investment performance and the length of the career break.

The calculations assume salaries increase by 2 per cent a year. The potential effect is smaller when a career break occurs later because there is less time for missed contributions and investment returns to compound.

For someone aged 40 earning £41,100, the model estimates £65,483 in missed contributions and a projected £133,211 difference in pension wealth when investment growth is included.

Women Can Face Greater Employment Gaps

The figures come as women remain less likely than men to work full-time during the years when many families have children. Figures from the Office for National Statistics cited in the calculations show that 84 per cent of men aged 22 to 29 work full-time, compared with 75 per cent of women. Among those aged 30 to 39, around 90 per cent of men work full-time compared with 66 per cent of women.

Part-time employment can reduce pension contributions because lower earnings generally mean smaller employee and employer contributions. Extended career breaks can remove workplace pension contributions altogether during the period away from employment.

Camilla Esmund, head of investor campaigns at Interactive Investor, said career breaks and reduced working hours can disproportionately affect women because they are more likely to take time away from employment or reduce their hours to care for children. She also pointed to childcare costs as a factor influencing decisions about returning to work.

Stephanie Faces the Reality

Stephanie says the calculations have prompted her to think more closely about her own retirement. She is no longer building her pension at the rate she would have while working, and says her existing savings will not be enough for a comfortable retirement. Her husband continues to pay into a workplace pension, but Stephanie expects their financial positions in retirement to differ.

Her experience illustrates how unpaid caring responsibilities can affect retirement saving. Parents who leave work, reduce their hours or delay returning to employment can spend years contributing less to their pensions.

What Can Help Rebuild Retirement Savings

People returning to employment may be able to increase their pension contributions through a workplace scheme, with employers potentially contributing alongside them. Personal pensions are another option, while pension contributions can qualify for tax relief depending on individual circumstances and the arrangement.

It can also be worth checking for pension pots left behind after previous jobs. Research published in 2024 estimated that about £31.1 billion was held in unclaimed, inactive or lost UK pension pots across almost 3.3 million pots. Consolidating pensions can sometimes simplify administration and reduce fees, but savers should check the charges, benefits and terms of existing schemes before transferring money.

For Stephanie, caring for her son remains the priority. Her experience shows how the financial consequences of stepping away from paid work can extend well beyond the career break itself. The calculations do not represent what every parent will lose, but they illustrate how missed pension contributions and lost investment growth can become substantial over time.
