How much do I need to retire?

There’s no single magic number — it depends on the life you want and what the State Pension covers. But there are solid benchmarks, and a simple way to turn “retire” into a pot with a figure attached.

The short answer

As a rough guide, a single person needs a pension pot of around £300,000–£490,000 for a moderate retirement and £540,000–£800,000 for a comfortable one, on top of the full State Pension. A common shortcut is 25× your annual spending: want £25,000 a year from your pot and you target £625,000. The State Pension (around £12,548 a year) reduces what your own savings must provide.

Forget the headline number for a second. Retirement planning works backwards: start with the life you want, cost it, then work out the pot behind it.

The most-used benchmark in the UK comes from the Pensions and Lifetime Savings Association, which prices three lifestyles. A minimum retirement — basics covered, no car — runs to about £13,400 a year for one person. Moderate — a small car, a two-week European holiday — is around £31,300. Comfortable, with regular treats and more travel, is roughly £43,900. For couples, who share many costs, the figures are about £21,600, £43,900 and £60,000.

Those are spending figures, after tax. The pot you need sits behind them — and here’s where the State Pension does heavy lifting.

£12,548/yr The full new State Pension in 2026/27 — it covers part of the gap, but only from State Pension age (66, rising to 67).

The full new State Pension is around £12,548 a year from State Pension age (66, rising to 67 by April 2028). For a couple with two full entitlements, that’s roughly £25,000 before any private savings — enough to cover a minimum lifestyle on its own. The gap between that and the life you want is what your pension pot has to fill.

The 25× rule, and why it’s only a starting point

The quick way to size a pot: take the annual income you want from your savings and multiply by 25. That’s the flip side of the 4% rule — the idea you can draw about 4% of a pot each year, rising with inflation, with a fair chance of it lasting 30 years.

The catch: 4% came from US research assuming a 30-year retirement. Retire early, or expect to live long, and many UK planners prefer a more cautious 3–3.5% — which pushes the multiple up toward 28–33×. So £25,000 a year might need £625,000 at 4%, but closer to £750,000 if you’re being careful.

What changes the number you need?

The benchmarks are a guide, not a target. Four things move your figure most.

£The lifestyle you want

Minimum, moderate or comfortable are worlds apart — from ~£13k to ~£44k a year for one person. Your real spending is the foundation.

Single or sharing

Couples share housing and bills, so two people need far less than double one person. Living alone is markedly more expensive in retirement.

%Your withdrawal rate

Drawing 4% needs a smaller pot than a cautious 3.5%. A longer or earlier retirement argues for the lower, safer rate — and a bigger pot.

!When you retire

Stop before State Pension age and you must fund those years entirely yourself — and before 55 (57 from 2028) you can’t touch a pension at all.

Pension pot needed for different incomes

A rough guide using the 25× rule (4% withdrawal), for income from your pot before the State Pension is added on top.

Income you want from your potPot needed (4% rule)Pot needed (cautious 3.5%)
£10,000/yr£250,000£286,000
£15,000/yr£375,000£429,000
£20,000/yr£500,000£571,000
£25,000/yr£625,000£714,000
£30,000/yr£750,000£857,000

Remember these are the figures from your own pot — the State Pension (around £12,548 a year) stacks on top once it starts, so the income you actually live on is higher. Up to 25% of a pension can usually be taken tax-free. Model your own target with the pension drawdown calculator.

A retirement number, worked through

One realistic example, to show how spending, the State Pension and the pot fit together.

Worked example Carol · single · wants a comfortable retirement at 66
  1. The lifestyle. Carol wants a comfortable standard — around £43,900 a year after tax.
  2. The State Pension. She’ll get the full new State Pension, about £12,548 a year, leaving roughly £31,000 to come from her own savings.
  3. The pot. At a 4% withdrawal rate, £31,000 a year needs about £775,000 — in the PLSA’s £540k–£800k range for comfortable.
  4. The caution. Wanting the pot to last, she plans around 3.5%, nudging the target nearer £885,000.
  5. The lump sum. She factors in taking up to 25% tax-free, shaping how she’ll draw the rest tax-efficiently.

The takeaway: Carol’s pot isn’t her income — the State Pension covers nearly a third of her target before her savings do anything. Costing the lifestyle first, then subtracting the State Pension, told her the real number her pension needs to hit.

Retirement income questions, answered

How much do I need to retire comfortably in the UK?
Industry benchmarks from the PLSA suggest a single person needs around £43,900 a year after tax for a comfortable retirement, or about £31,300 for a moderate one. Behind that sits a pension pot of roughly £540,000–£800,000 for comfortable, on top of the full State Pension. Couples need less per person because they share costs — around £60,000 a year combined for comfortable.
What is the 25 times rule for retirement?
It’s a quick way to size a pension pot: multiply the annual income you want from your savings by 25. Want £20,000 a year from your pot and you target £500,000. It’s the mirror of the 4% rule — drawing about 4% a year. For a long or early retirement, a more cautious 3–3.5% is often used, which raises the multiple toward 28–33 times.
How much State Pension will I get?
The full new State Pension is around £12,548 a year in 2026/27, paid from State Pension age (66, rising to 67 by April 2028). You need about 35 qualifying years of National Insurance for the full amount, and at least 10 years for any. You can check your forecast on GOV.UK. It reduces the private pot you need, but only from State Pension age.
Can a couple retire on less than two singles?
Yes, considerably less per person. Couples share housing, energy, council tax and many other costs, so two people need far less than double what one person does. The PLSA figures show a comfortable lifestyle costing about £43,900 for one person but around £60,000 for a couple — well under double. Living alone is markedly more expensive in retirement.
How much do I need to retire early?
More than for a standard retirement, for two reasons: you fund more years, and you can’t claim the State Pension or access a private pension (55, rising to 57 in 2028) until later. An early retiree must bridge those years entirely from accessible savings, and a longer retirement argues for a cautious 3–3.5% withdrawal rate and a bigger pot.
Does the 4% rule work in the UK?
It’s a useful starting point but originated in US research assuming a 30-year retirement. For longer or earlier UK retirements, many planners prefer a more cautious 3–3.5%. The biggest risk is sequence-of-returns risk — poor returns early on can permanently dent a pot — which a cash buffer and flexible spending help manage.
How much of my pension is tax-free?
You can usually take up to 25% of your pension pot tax-free, subject to an overall lump sum allowance. The remaining 75% is taxed as income when withdrawn. Planning how and when to take the tax-free portion, alongside ISAs and the State Pension, can keep more of your retirement income out of higher tax bands.

How this guide is built

Retirement income benchmarks follow the PLSA Retirement Living Standards; the State Pension figure, access ages and the 25% tax-free lump sum follow current GOV.UK guidance. Pot figures use the 25× (4%) rule as an illustration — returns are not guaranteed and your own figure depends on circumstances.
