Key takeaways

  • Estimate your desired retirement income, then subtract guaranteed income such as the State Pension
  • A pot of around 25 times your annual shortfall is a rough guide, not a guarantee
  • Start early, increase contributions over time and take full advantage of employer and tax help
  • Review your progress every year
  • If you are behind, increase saving, delay retirement or reduce planned spending, and get free guidance

There is no single answer to how much you need for retirement. It depends on the lifestyle you want, when you stop work, what you already have and how long you live. But there are ways to make a sensible estimate and, more importantly, to take steps now that make it easier. This guide gives you a practical method and some rules of thumb, with the caveat that all projections are uncertain.

Step 1: think about the lifestyle you want

Start with what you expect to spend. Some costs fall in retirement, such as commuting, pension contributions and sometimes a mortgage. Others may rise, including leisure, travel, heating and care. A common rule is that people need around two thirds to three quarters of their pre-retirement income, but many people need less or more. The Pensions UK Retirement Living Standards give examples of the annual income required for minimum, moderate and comfortable lifestyles for single people and couples. Check the latest figures on their website.

A good way to estimate your own spending is to build a budget. Our budget planner and guide to making a budget can help. Then adjust for retirement.

Step 2: add up your guaranteed income

  • State Pension: check your forecast on GOV.UK. See state pension explained.
  • Defined benefit pensions from past employers
  • Other regular income, such as rent or part-time work

Step 3: estimate the pot you need

A common rule of thumb is to divide the annual income you need from your pot by a withdrawal rate. A 4% rule suggests that if you withdraw 4% of your pot in the first year, adjusting for inflation each year, it could last around 30 years. That means a pot of around 25 times your annual shortfall. For example, if you need an extra £10,000 a year, you would aim for around £250,000. This is a guideline only, not a guarantee. The right rate depends on investment returns, inflation, how long you live, how flexible you are and whether you buy an annuity.

Using an annuity can provide a guaranteed income for life. Rates depend on your age, health and market conditions, so check quotes. Different strategies are described in personal pensions and SIPPs.

Rules of thumb for saving

Several rules of thumb exist, and none is right for everyone:

  • Half your age: some suggest saving a percentage of your income equal to half your age when you start. For example, start at 30 and save around 15% of income (including employer contributions), then maintain it.
  • Total contributions of 12 to 15% of salary: often quoted as a rough target across a career, including the employer's share.
  • Auto-enrolment minimums (currently 8% of qualifying earnings): a starting point, but often not enough alone for a comfortable retirement.

Step 4: take advantage of employer and tax help

  • Make sure you get the full employer contribution. If your employer matches contributions above the minimum, increasing your payments can be like getting a pay rise.
  • Use tax relief. Pension contributions receive tax relief. See workplace pensions explained.
  • Increase contributions when you get a pay rise. Put part of each increase towards your pension.
  • Use ISAs for flexibility. See ISAs explained.

Step 5: check your progress

  • Check your pension statements each year
  • Use the pension calculator on MoneyHelper to see if you are on track
  • Combine old pensions or at least know where they are; the Pension Tracing Service can help
  • Review when your circumstances change, such as a new job, marriage, divorce, children or inheritance

Our savings growth calculator shows how regular contributions might grow under different assumptions. Real returns will vary and are not guaranteed.

If you are behind

  • Increase contributions, even by 1 or 2%, and increase them regularly
  • Delay retirement by even a year or two. It gives you more years of contributions, a larger pot and fewer years of drawing income.
  • Reduce planned spending in retirement
  • Fill gaps in your National Insurance record if worthwhile
  • Defer your State Pension, if it makes sense for you
  • Use your home equity later in life, if appropriate. Get independent advice first.
  • Work part-time in the early years of retirement
  • Check for benefits, such as Pension Credit
  • Get free guidance from MoneyHelper and Pension Wise

If you are in debt

If you have expensive debts, paying them off is often a priority, but do not abandon employer pension contributions, because they are valuable. If you are struggling, get free advice from StepChange, Citizens Advice or National Debtline. See how to deal with debt.

Factors that can change the picture

  • Inflation, which reduces what your money can buy
  • Investment returns, which are uncertain
  • Living longer than expected
  • Care costs, which can be significant
  • Changes in tax and pension rules
  • Health changes
  • Family responsibilities

Because of this uncertainty, aim to build a margin of safety and review your plan regularly.

A simple worked example

Suppose you are 35, earn £35,000 and want about £25,000 a year in retirement. You expect the State Pension to provide roughly £11,000 of that (check your own forecast), leaving a shortfall of about £14,000. Using the 25 times rule, you would aim for a pot of around £350,000 in today's money. If your workplace pension already holds £20,000 and you pay in 8% of qualifying earnings, you can test how far that gets you with the calculators on MoneyHelper, then see what happens if you add 2% or retire a year later. The figures here are for illustration only and are not a forecast or a recommendation.

Common mistakes

  • Waiting until your forties or fifties to start
  • Opting out of auto-enrolment without a strong reason
  • Forgetting about old pensions
  • Assuming the State Pension will be enough
  • Ignoring charges and investment risk in a long-term pot
  • Taking money out too early, which can mean paying tax and losing years of growth

Frequently asked questions

How much do I need in my pension pot?
It depends on your spending, other income and how long you live. Work out your shortfall and use a rule of thumb as a starting point.
Is the State Pension enough to live on?
For most people it covers basics only. Many want additional income from other pensions and savings.
Should I save in a pension or an ISA?
Pensions offer tax relief and often employer contributions, while ISAs offer flexibility. Many people use both.
How can I find out where my old pensions are?
Use the free Pension Tracing Service on GOV.UK, and contact old employers or providers.
