How Much Do I Need to Save for Retirement in the UK?

The honest answer

There's no single correct number — it depends on the lifestyle you want in retirement, when you want to retire, what other income you'll have, and how long you live. But there are well-established benchmarks that give you a useful starting point.

The PLSA Retirement Living Standards

The Pensions and Lifetime Savings Association (PLSA) publishes widely used benchmarks for annual retirement income:

• Minimum standard: £14,400/year — covers basic needs with some social activities. Assumes State Pension covers most of this.
• Moderate standard: £31,300/year — more financial security and flexibility. Allows a week's European holiday, some car costs.
• Comfortable standard: £43,100/year — more financial freedom. Regular holidays, new car every 5 years, home improvements.

These figures are for a single person. Couples need slightly less per head due to shared costs.

How much pension pot do I need?

A common rule of thumb is the "4% rule" — you can sustainably withdraw 4% of your pension pot per year without it running out over a 25–30 year retirement. To work backwards:

• Moderate retirement (£31,300): subtract State Pension (£11,502) = need ~£19,800/year from pension. Pot needed: ~£495,000
• Comfortable retirement (£43,100): subtract State Pension = need ~£31,600/year. Pot needed: ~£790,000

The contribution benchmarks

As a general guide to what you should be saving as a percentage of your salary:

• Start at 25: Save 12–15% of salary (including employer contributions)
• Start at 35: Save 17–20% of salary
• Start at 45: Save 25–30% of salary

These are rough guides — your actual target depends on your existing pot, planned retirement age, State Pension entitlement, and desired lifestyle.

The "half your age" rule

A simple starting point: take the age you start saving, halve it, and that's the percentage of your pre-tax salary you should be saving each year. Start at 30? Save 15%. Start at 40? Save 20%. This includes employer contributions.

Am I on track?

A good benchmark for pension pot at different ages (targeting a moderate retirement at 67):

• Age 35: 1× annual salary
• Age 45: 3× annual salary
• Age 55: 6× annual salary
• Age 65: 10× annual salary

What if I've started late?

Later starters need to save a higher proportion of salary, but it's never too late to start. Even at 50, a focused decade of high contributions can make a meaningful difference. The key actions are: maximise employer matching, carry forward unused annual allowance if possible, and consider a SIPP alongside your workplace pension for tax efficiency.
