Ask ten people how much they need to retire early and you’ll get ten different answers — usually a big round number plucked from thin air. “A million should do it.” “Half a million?” The truth is there’s no single magic figure, and chasing someone else’s number is one of the quickest ways to either put your dream off forever or stop working before you’re truly ready.
The real question isn’t “what’s the number?” It’s “what does the life I want actually cost — and how do I fund it in the years before my pensions and State Pension arrive?” Let’s walk through it.
Start with the life, not the lump sum
The most useful starting point I know is the Retirement Living Standards published by the Pensions and Lifetime Savings Association (PLSA). Rather than one target, they describe three lifestyles and roughly what each costs a single person per year (2026 figures, assuming you own your home outright):
- Minimum — around £13,900 a year. The basics covered and a week’s holiday in the UK, but no car.
- Moderate — around £32,700 a year. More security and freedom: a car, a two-week holiday abroad, some eating out and gifting.
- Comfortable — around £45,400 a year. Financial freedom with a few luxuries: longer holidays, home improvements, a newer car.
For couples the totals are higher but the cost per person is lower, because so much is shared — roughly £22,500, £45,400 and £62,700 a year for those same three lifestyles.
One important catch: these assume your home is paid off and don’t include rent or a mortgage. If you’ll still have housing costs in retirement, add them on top.
Seeing it this way reframes everything. You’re not saving towards an abstract million — you’re funding a specific lifestyle. And once you know roughly what your life costs, we can work backwards to the pot behind it.
Why retiring early changes the maths
Stopping work at 55 or 60 is a very different challenge from retiring at 67, for two reasons people often overlook.
1. There’s a gap to bridge. You normally can’t access a private or workplace pension until age 55 (rising to 57 from April 2028), and the State Pension doesn’t start until your State Pension age — currently 66, and rising to 67 between now and 2028. So if you want to stop at, say, 55, you may need to fund several years entirely from other savings before your pensions become available — and more years still before the State Pension arrives. Those “bridge” years are where a lot of early-retirement plans quietly come unstuck.
2. Your money has to stretch further. Retire ten years early and you might need your savings to last 35 years or more — while giving them ten fewer years to grow. That combination usually means early retirement calls for either a larger pot, a more modest income, or a more cautious rate of drawing down. Often a blend of all three.
The State Pension: your foundation, but not yet
The full new State Pension for 2026/27 is £12,548 a year. For most people that’s the bedrock the rest of the plan is built on — but only from State Pension age. As an early retiree, everything before that date has to come from you. It’s well worth checking your State Pension forecast at gov.uk, because what you’ll actually receive depends on your National Insurance record, and there may be gaps worth filling.
So how big a pot are we talking about?
To give a rough sense of scale, the PLSA illustrates that a single person might need somewhere around £335,000–£505,000 to support a moderate lifestyle, or £560,000–£845,000 for a comfortable one, on top of a full State Pension. Those are broad, illustrative ranges based on buying a guaranteed income for life (an annuity), and your own figure could look quite different depending on how you choose to draw your money, your other assets, and your tax position.
You’ll also hear rules of thumb — such as drawing around 4% of your pot a year — but I’d treat these with real caution when you’re retiring early. A longer retirement leaves far less room for error, so the sustainable figure is often lower. A rule of thumb is a starting point for a conversation, not a plan.
The only number that really matters is yours
Here’s the honest truth: the PLSA standards and pot ranges are helpful signposts, but none of them is your number. Yours depends on your actual spending, your pensions and savings, your partner’s position, your tax, when you want to stop, and how long the money needs to last.
This is exactly what cash flow forecasting is for, and it’s central to how I work with clients. We map your real income and outgoings, layer in your pensions, ISAs, savings and the State Pension, allow for tax and inflation, and model it year by year. The result answers the questions that actually keep people up at night: Can I afford to stop at 58? Will the money last? What happens if markets fall in my first few years? How do I cover the gap until my pensions unlock? It turns “I hope so” into something you can actually see.
Giving yourself the best shot
Whatever your target, a few things tend to move the needle:
- Make the most of pension tax relief. Contributions are topped up by tax relief, which makes pensions one of the most efficient ways to build your pot — and if you have unused allowance from previous years, “carry forward” may let you contribute more.
- Don’t leave employer contributions on the table. If your employer will match higher contributions, that’s effectively free money towards your future.
- Build a bridge with ISAs and savings. Because ISAs can be accessed at any age, they’re often the piece that funds those early years before your pensions unlock.
- Track down lost pensions. Many of us have old workplace pots we’ve lost sight of. Bringing them together can make the whole picture clearer — and sometimes cheaper to run.
Let’s find your number
Early retirement isn’t reserved for lottery winners or high earners — far more often, it’s the result of a clear plan, started early enough and reviewed regularly. If you’d like to know what your early-retirement number looks like, and whether the date you have in mind is realistic, I’d be glad to help.
