How Much Do You Need to Retire?

The Pensions and Lifetime Savings Association (PLSA) publishes retirement living standards that provide helpful benchmarks for how much income you need in retirement:

Lifestyle LevelSingle PersonCouple
Minimum£14,400/year£22,400/year
Moderate£31,300/year£43,100/year
Comfortable£43,100/year£59,000/year

These figures assume you own your home outright. A minimum lifestyle covers basic needs but leaves little room for extras. A moderate lifestyle includes a two-week European holiday each year and some leisure spending. A comfortable lifestyle includes regular longer holidays, a newer car, and more generous spending.

Quick calculation: To generate £31,300 per year (moderate, single) you would need a pension pot of roughly £390,000 to £480,000, assuming a 4% withdrawal rate plus the full State Pension.

The State Pension

The State Pension forms the foundation of most people’s retirement income. For the 2025/26 tax year:

  • Full new State Pension: £230.25 per week (£11,973 per year)
  • You need 35 qualifying years of National Insurance contributions for the full amount
  • You need at least 10 qualifying years to receive any State Pension
  • Current State Pension age: 66 (rising to 67 between 2026 and 2028)

You can check your State Pension forecast and National Insurance record at gov.uk to see how much you are on track to receive.

Retirement Planning by Age

In Your 20s and 30s

Time is your greatest asset. Thanks to compound growth, even modest contributions in your 20s can grow significantly by retirement. Key actions:

  • Ensure you are enrolled in your workplace pension and contributing at least enough to get the full employer match
  • Consider increasing contributions by 1% each year or whenever you receive a pay rise
  • Take advantage of higher-risk investments that have more time to recover from market downturns
  • Check for any old pensions from previous jobs and consider consolidating them

In Your 40s

This is often when retirement planning becomes more serious. With 20–25 years until retirement, there is still time to make a significant difference:

  • Calculate your retirement income target using the PLSA benchmarks above
  • Review your pension investments to ensure they match your risk tolerance and time horizon
  • Consider making additional voluntary contributions (AVCs) if your workplace scheme allows
  • Check your State Pension forecast and fill any gaps in your National Insurance record

In Your 50s

Retirement planning becomes urgent. Key actions include:

  • Get a detailed retirement forecast from your pension providers
  • Book a free Pension Wise appointment to understand your options
  • Consider whether you need professional financial advice
  • Start thinking about how you will access your pension (drawdown, annuity, or a combination)
  • Review your investment strategy – you may want to gradually reduce risk as you approach retirement

In Your 60s

Final preparations for retirement:

  • Confirm your State Pension start date and amount
  • Decide on your retirement income strategy (see our drawdown vs annuity guide)
  • Consider taking professional pension advice for withdrawals
  • Plan your tax-free lump sum and how you will use it
  • Think about part-time work or phased retirement as a transition

How to Access Your Pension

From age 55 (rising to 57 from April 2028), you have several options for accessing your defined contribution pension:

OptionHow It WorksBest For
Tax-free lump sumTake up to 25% of your pot tax-freeEveryone – this is usually worth taking
Income drawdownKeep your pension invested and draw a flexible incomeThose who want flexibility and control
AnnuityBuy a guaranteed income for lifeThose who want certainty and security
Lump sums (UFPLS)Take lump sums as needed (25% of each is tax-free)Those with smaller pots or irregular needs
CombinationMix of the above optionsMost people – flexibility with some security
Tax warning: Only the first 25% of your pension is tax-free. The remaining 75% is added to your income and taxed at your marginal rate. Taking too much in one year could push you into a higher tax bracket.

Common Retirement Planning Mistakes

  • Starting too late – every year you delay costs you in lost compound growth
  • Only contributing the minimum – the auto-enrolment minimum of 8% (including employer contributions) is unlikely to provide a comfortable retirement
  • Ignoring fees – a 1% difference in annual charges can reduce your pension pot by over 25% over 30 years
  • Not claiming full tax relief – higher-rate taxpayers need to claim extra relief through their tax return
  • Cashing in your pension too early – withdrawing your entire pot at 55 leaves decades without retirement income
  • Underestimating how long retirement lasts – a 65-year-old today has roughly a 1 in 4 chance of living to 95

Frequently Asked Questions

According to the Pensions and Lifetime Savings Association, a single person needs around £31,300 per year for a moderate retirement lifestyle, and £43,100 for a comfortable retirement. A couple needs £43,100 for moderate and £59,000 for comfortable. These figures include housing costs for those who have paid off their mortgage.
You can currently access most private and workplace pensions from age 55 (rising to 57 from 6 April 2028). The State Pension age is currently 66 and is rising to 67 between 2026 and 2028, with a further increase to 68 expected in the future.
It is never too late to start. At 50, you still have 15 to 17 years before State Pension age, which is enough time to build a meaningful retirement fund. You may need to save more aggressively, but pension tax relief means the government adds 20% to 45% to your contributions depending on your tax rate.
The full new State Pension for 2025/26 is £230.25 per week (£11,973 per year). You need 35 qualifying years of National Insurance contributions to get the full amount. You can check your State Pension forecast at gov.uk.
