Is £400k Enough to Retire On in the UK? (2026)

A £400,000 pension pot delivers a solidly moderate retirement alongside the State Pension. We break down the 2026/27 annuity and drawdown income it produces, and the tax planning that keeps more of it yours.

12 min read Updated October 2026
Bottom line: £400k funds a solidly moderate retirement, if not quite a comfortable one. A level annuity purchased after the 25% tax-free lump sum pays in the region of £15,600 a year; combined with the £12,548 full State Pension (2026/27) you reach about £28,148 – miles past the PLSA Minimum (£14,400) and only narrowly behind the £31,300 Moderate standard.

£400,000: Solidly Moderate Territory

With £400k saved, you have moved beyond the anxious end of retirement planning. The question is no longer “will this work?” but “how well can it work?” – and the honest answer is a dependable, moderate lifestyle with meaningful room to manoeuvre, provided the drawdown and tax decisions are made sensibly.

The sections below put hard 2026/27 numbers on that claim: the income the pot generates, where it sits against the recognised benchmarks, and the tax detail that decides how much of it you keep.

Projection: Take 25% tax-free cash from £400,000 and the balance buys a level annuity around £15,600 a year. With the full State Pension of £12,548 added, total annual income lands near £28,148.

Where £400k Sits on the Living Standards Scale

Here is that projected income measured against the three PLSA single-person retirement budgets:

StandardAnnual Income NeededYour Total (Annuity + State Pension)Shortfall/Surplus
Minimum£14,400£27,573+£13,173
Moderate£31,300£27,573-£3,727
Comfortable£43,100£27,573-£15,527

Income Routes for a £400,000 Pot

A quarter of the pot – £100,000 – is available as tax-free cash, which leaves £300,000 to produce your ongoing income. The two classic structures:

Annuity: income you cannot outlive

Exchanged for a level annuity at age 67, £300,000 currently delivers about £15,600 a year, paid as roughly £1,300 a month until death. It is the simplest possible arrangement, though the payment never grows and inflation-linked versions open substantially lower.

Drawdown: income with growth potential

Kept invested in flexi-access drawdown instead, the £300,000 supports a 4% withdrawal of around £12,000 a year (£1,000 monthly), rising or falling with portfolio performance. Choosing 3.5% – some £10,500 annually – trades income today for better durability across 30+ years.

Tax: The Difference Between Gross and Spendable

Your £100,000 lump sum arrives entirely free of income tax. After that, each withdrawal is taxable, assessed alongside the State Pension and any other income you have.

For 2026/27 the personal allowance is £12,570 and the full State Pension absorbs £12,548 of it – a margin of £22 – so effectively every pound you draw privately is taxed from 20% upwards.

At £400k the higher-rate boundary matters routinely, not occasionally: income and withdrawals above £50,270 in a tax year attract 40%, so phasing larger withdrawals across years protects a meaningful amount of money.

Running £400k Well Over a Long Retirement

  • Draw on a schedule, not on impulse: Regular, measured withdrawals avoid both 40% tax surprises and crystallising losses in down markets.
  • Put the £100,000 to strategic use: Tax-free cash can bridge the years before State Pension age – or fund deferral, which lifts that pension by about 5.8% per year delayed.
  • Blend your income sources: Many retirees annuitise enough to cover fixed outgoings and keep the balance invested for flexibility and growth.
  • Guard against fee drag: A long retirement multiplies every basis point of charges; cheap platforms and index funds keep the compounding working for you.
  • Review once a year, minimum: Withdrawal rates should respond to markets and your remaining balance – small early adjustments beat big late ones.

Pushing Beyond Moderate

If your ambitions run past the moderate standard towards genuine comfort, the remaining distance can be covered before or even during retirement:

  • A final contribution push: Carry forward lets high earners shelter several years of unused allowance at once; salary sacrifice adds NI efficiency.
  • Make sure nothing is missing: Verify you hold every pension you have ever accrued using the Government’s pension tracing service.
  • Shift the retirement date modestly: Delaying by even a year raises sustainable income on three fronts simultaneously.
  • Treat housing equity as a reserve: A future downsize can underwrite more confident spending from the pension today.

Frequently Asked Questions

For a moderate lifestyle, essentially yes. Including the full State Pension you can expect around £27,573 a year – far beyond the PLSA minimum and within touching distance of the moderate benchmark, which modest extra income or careful budgeting covers.
After the 25% tax-free lump sum, drawing 4% of the remainder provides roughly £12,000 a year, an approach with a reasonable track record of lasting 25-30 years. A more guarded 3.5% rate delivers £10,500 a year and better odds of 30+ years.
A dependable, moderate-leaning retirement: alongside the State Pension the pot supports comfortable day-to-day living, holidays, hobbies and a car, with genuine resilience against unexpected costs.
PLSA research puts the comfortable single-person standard at about £43,100 a year. After the full State Pension contributes £12,548, around £30,552 must come from your own savings – implying a pot close to £590,000.
More feasible than with smaller pots, but still costly. Retiring at 57 means roughly 10 self-funded years before the State Pension lands at 67; £400k can absorb that bridge, at the price of a noticeably lower sustainable income thereafter.
If your target sits above what £400k supports, combine remedies: push contributions harder with salary sacrifice and carry forward, sweep for forgotten pensions via the Pension Tracing Service, defer retirement slightly, or bank on downsizing to release equity later.
