How much pension do I need to retire in the UK?
The short answer depends on what kind of retirement you want. The Pensions and Lifetime Savings Association (PLSA) publishes three retirement living standards that give you concrete numbers to aim for. These aren't vague aspirations. They're based on actual spending data from real retirees.
The three PLSA retirement living standards (2026)
The PLSA standards tell you what annual income you need for each level of retirement. These figures are for a single person living outside London:
| Standard | Annual income needed | What it covers |
|---|---|---|
| Minimum | £14,400 | Basic needs met. Budget supermarket shops. A week's holiday in the UK. No car. |
| Moderate | £31,300 | More flexibility. 2 weeks in Europe. Running a car (3-year-old). Eating out occasionally. |
| Comfortable | £43,100 | Regular beauty treatments. 3 weeks in Europe. A newer car. £50/week on food treats. |
For couples, the figures are £22,400 (minimum), £43,100 (moderate), and £59,000 (comfortable). These assume you own your home outright. If you're still paying rent or a mortgage in retirement, add those costs on top.
The gap between state pension and what you need
The full state pension for 2026/27 is £11,502 per year (£221.20/week). That leaves a gap you need to fill from your private pension:
| Standard | Income needed | State pension | Gap to fill |
|---|---|---|---|
| Minimum | £14,400 | £11,502 | £2,898 |
| Moderate | £31,300 | £11,502 | £19,798 |
| Comfortable | £43,100 | £11,502 | £31,598 |
The minimum standard is almost achievable on state pension alone. But for a moderate retirement, you need your private pension to produce nearly £20,000 per year. That requires a substantial pot.
How big a pot do you need?
Using the 4% withdrawal rule (which estimates how much you can safely draw each year without running out over a 30-year retirement), here's what pot sizes you need at retirement age 67:
| Standard | Annual gap | Pot needed (4% rule) |
|---|---|---|
| Minimum | £2,898 | £72,450 |
| Moderate | £19,798 | £494,950 |
| Comfortable | £31,598 | £789,950 |
Half a million pounds for a moderate retirement. That sounds daunting. And it is, for anyone starting late. But compound growth over decades makes it achievable if you start early enough.
The 4% rule: what it actually means
The 4% rule comes from research by William Bengen in 1994 (and later confirmed by the "Trinity Study"). It says that if you withdraw 4% of your pot in your first year of retirement, then adjust that amount for inflation each year, you have a very high probability (around 95%) of your money lasting 30 years.
It assumes a portfolio split roughly 50/50 between equities and bonds. In the UK context, with our current gilt yields and equity valuations, some researchers suggest 3.5% is more appropriate. But 4% remains the standard benchmark.
If you want to be more conservative, use 3.5%. That means you need a larger pot: £565,657 for the moderate standard instead of £494,950.
When you start matters enormously
Compound growth rewards early starters disproportionately. Here's what happens if you need a £500,000 pot by age 67, assuming 5% annual growth after charges:
| Starting age | Years to grow | Monthly contribution needed | Total you pay in | Growth earned |
|---|---|---|---|---|
| 25 | 42 years | £295 | £148,680 | £351,320 |
| 35 | 32 years | £555 | £213,120 | £286,880 |
| 45 | 22 years | £1,080 | £285,120 | £214,880 |
| 55 | 12 years | £2,520 | £362,880 | £137,120 |
Starting at 25, you pay in less than £150,000 and compound growth does the rest. Start at 45 and you're fighting against time; you need to contribute £1,080 per month, and over half the pot comes from your own money rather than growth. Start at 55 and it's nearly impossible without a very high income.
What if you're starting late?
If you're 45 and haven't started saving, don't panic. But be realistic. Here are your options:
Increase contributions aggressively. Even £500 per month from age 45 gets you around £231,000 by 67 (at 5% growth). Combined with a full state pension, that gives you roughly £20,700 per year. Just above the minimum standard, but below moderate.
Work longer. Every extra year at work means one more year of contributions, one more year of growth, and one fewer year your pot needs to last. Working to 70 instead of 67 can increase your income in retirement by 20-25%.
Reduce your target. If a moderate retirement costs £31,300, maybe you aim for something between minimum and moderate. A £250,000 pot gives you £10,000/year from drawdown, plus £11,502 state pension = £21,502. That's more than minimum and approaching moderate if you've paid off your mortgage.
Auto-enrolment: is it enough?
The standard 8% auto-enrolment contribution (5% employee + 3% employer) is better than nothing but won't get most people to a moderate retirement. Here's why:
On a £30,000 salary, 8% of qualifying earnings (£23,760) is £1,901 per year, or £158 per month. Starting at age 22, contributing £158/month for 45 years at 5% growth gives you approximately £303,000. That's enough for the minimum standard with some breathing room, but falls well short of moderate.
To hit the moderate target on a £30,000 salary, you'd need total contributions of around 15% of qualifying earnings. That means topping up beyond auto-enrolment minimums. Even an extra £100 per month makes a significant difference over 30+ years.
Tax relief: free money from HMRC
Every pound you put into a pension gets tax relief. For basic-rate taxpayers, it costs you 80p to put £1 into your pension (the other 20p comes from HMRC). For higher-rate taxpayers, it effectively costs just 60p per £1.
If you earn £50,000 and contribute £200/month net to your pension, it actually becomes £250/month in your pot (basic rate). And you can claim back an extra £50 through self-assessment because you're a higher-rate taxpayer on part of your income. So your £200 becomes £312.50 in real pension value. That's a 56% boost.
Drawdown vs annuity at retirement
You don't have to choose one or the other. Many people take their 25% tax-free lump sum, buy a small annuity to cover essential bills (guaranteeing they won't run out of money for necessities), and put the rest into drawdown for flexibility.
Current annuity rates at age 67 are approximately 5.5% for a single life, level annuity. So £100,000 buys you about £5,500 per year, guaranteed for life. That's not going to increase with inflation, but you'll receive it no matter how long you live.
Drawdown gives you more potential income (if markets perform well) and leaves money for your family if you die early. But it can run out if you withdraw too much or if there's a sustained market crash in your early retirement years.
Key numbers to remember
- State pension 2026/27: £221.20/week (£11,502/year)
- You need 35 NI years for the full amount, minimum 10 years
- PLSA moderate standard: £31,300/year single, £43,100/year couple
- Pot needed for moderate: approximately £500,000
- The 4% withdrawal rule: divide your target income by 0.04 to get your pot target
- Starting 10 years earlier roughly halves the monthly contribution needed
- Auto-enrolment minimums (8%) won't get most people to moderate
