The simple answer is 'longer than you might think', thanks to increasing life expectancy.
You'll need to plan carefully to make your pension savings last throughout your retirement, and perhaps beyond if you want to pass some money on to loved ones.
Whether you’re unsure if you have enough to retire, or are already accessing your savings, our money guidance service can talk you through your options. Which? Money members get unlimited access to them via phone.
Find out moreUntil 2011, there was a default retirement age of 65, but now the decision about when to stop working is in your hands.
In fact, more people are choosing to put off retirement. The employment rate at age 65 has seen one of the largest increases when compared to other age groups, up from 26.9% in 2014 to 40.4% in 2024.
The average age of exit from the workforce has reached a high of 65.8 for men and 64.7 for women, according to DWP data in September 2025.
For many people, the decision about when to retire comes down to when they feel they can afford it.
You can claim state pension when you reach the state pension age (rising from 66 to 67 between 2026 and 2028), even if you're still working.
With private pensions, the earliest you can start taking this money is when you turn 55.
Data from the Office for National Statistics (ONS) shows that men aged 65 in the UK in 2021 to 2023 can expect to live on average a further 18.5 years (to age 83.5), while women aged 65 can expect to live on average a further 21.0 years (to age 86).
This means you'll need to plan to make your savings last at least a couple of decades in retirement.
Of course, you could easily live for longer. The number of centenarians is on the rise: according to the ONS, there were 16,600 people aged 100 or older living in England and Wales in 2024 - more than double the number in 2004.
Saving as much as possible, as early as possible, will help put you in the strongest financial position for life after work. But it's hard to know exactly how much you should aim for.
Pensions UK has developed three ‘retirement living standards’ to help address this problem. These reflect the annual amounts you’d need for a minimum, moderate and comfortable standard of living in retirement.
The latest figures show single-person households need £13,900 a year for minimum standard of living, rising to £32,700 for a moderate standard and £45,400 to be comfortable. For couples, the equivalent figures are £22,500, £45,400 or £62,700.
To help you plan for retirement, you'll need to understand your options for accessing your pensions.
If you have a defined benefit pension (also known as a final salary pension) you will receive a guaranteed income for the rest of your life. This is either based on your ‘career average’ earnings, or your final salary.
Each year the amount will usually increase, though not necessarily in line with inflation.
This type of pension is increasingly rare, as they are expensive for employers to offer.
With defined contribution pensions, the onus is on you to make sure your money lasts.
How much income you get depends on the value of your pot and how you choose to access it. You have several options, including:
In your sixties you’ll receive a boost to your retirement income in the form of the state pension. The state pension age is rising from 66 to 67 between 2026 and 2028.
How much you get depends largely on your National Insurance record.
In 2026-27, those qualifying for the full new state pension receive £241.30 a week.
Our calculations show that couples need a combined pot of between £332,000 and £389,000 alongside their state pension to achieve Pensions UK's moderate living standard (£45,400 a year) if accessing their money via pension drawdown, or between £340,000 and £510,000 if buying an annuity.
The equivalent figures for those living alone are between £329,000 and £386,000 if using drawdown, or between £335,000 and £505,000 if buying an annuity.
Retirees living alone face a tougher challenge, given their higher relative expenditure combined with lower state pension and tax-free allowance compared with a couple.
| Total needed if buying an annuity* | Total needed if using drawdown** | |||
| One-person household | Two-person household | One-person household | Two-person household | |
| Comfortable retirement living standard | £560,000-£845,000 | £630,000-£910,000 | £552,000-£646,000 | £615,000-£720,000 |
| Moderate retirement living standard | £335,000-£505,000 | £340,000-£510,000 | £329,000-£386,000 | £332,000-£389,000 |
Notes: Figures assume you get the full level of state pension (£12,548 a year in 2026-27). * The annuity figures are based on rates of between £5,000 and £7,500 per £100,000 of pension savings. **Drawdown figures are based on a saver withdrawing all their money over 20 years from age 65 and assume annual investment growth of 3% and 5%, inflation of 1% and charges of 0.75%.
