Young Britons face a daunting financial challenge, with new analysis showing Generation Z will need more than £3million in pension savings to secure a comfortable retirement.
The findings come from wealth management firm Rathbones Group's latest research.
The sum reflects inflation's long-term erosion of purchasing power.
A 25-year-old starting work today must build £3.1million by retirement age to sustain living standards in later life.
That equates to £1.4million in present-day terms for someone retiring at 65.
Couples would need £4.3million combined to retire comfortably.
The research uses Pensions and Lifetime Savings Association (PLSA) benchmarks, assuming two per cent annual inflation during saving years and across a 25-year retirement period.
The calculations show how even modest inflation compounds over decades, transforming the savings required for Britain's youngest workers.
Monthly contributions also highlight the scale of the challenge.

Building a £3.1million fund requires about £1,600 a month, assuming two per cent annual increases and five per cent investment growth.
Rebecca Williams, divisional lead of financial planning at Rathbones, called the figures "shocking".
She said they serve as "a stark reminder of how inflation can quietly erode retirement savings".
Ms Williams added: "What's considered an adequate retirement nest egg today may barely scratch the surface of what Gen Z will need when they retire."
Cash savers face an even greater burden.
Those relying on two per cent interest would need nearly £3,000 in monthly contributions – almost double the pension route.

These projections exclude the state pension, currently worth up to £11,975 a year.
They also omit potential costs such as housing, social care and tax on withdrawals, meaning the true requirement could be higher.
The challenges reflect wider economic pressures on Generation Z.
High housing costs absorb a large share of incomes, while student loan repayments reduce saving capacity.
Ms Williams said: "Younger generations face higher hurdles – from high housing costs to student debt – while also needing to ensure their savings stretch further to account for greater longevity."
The cost of living squeeze further limits young workers' ability to save.
Final salary pension schemes have largely disappeared, shifting responsibility onto individuals.
Auto nenrolment provides only basic coverage, and minimum contributions fall short, particularly for gig economy workers with irregular income.
Frequent job changes add to the problem, leaving workers with multiple small pension pots across different providers.
These scattered accounts are often neglected, weakening long-term wealth building.
Rathbones said starting early and saving consistently is essential.
Ms Williams noted: "Even modest, regular contributions can grow substantially over time."
LATEST DEVELOPMENTS:
Longer investment horizons also allow younger workers to take more risk and benefit from compound growth
| GETTYShe said maximising workplace pension contributions is "essentially free money" thanks to tax relief and employer top-ups.
Longer investment horizons also allow younger workers to take more risk and benefit from compound growth.
The analysis shows a moderate retirement lifestyle requires £2.2million in savings for individuals, while minimum standards need £947,700.
Even at these lower levels, the commitment required is substantial.
Ms Williams also pointed to family help: "We're seeing the Bank of Mum and Dad support younger generations, from junior SIPPs to gifts for adult children."
Such intergenerational support is playing an increasing role as Generation Z faces unprecedented retirement funding requirements.
