Can I retire with £1 million?
A million-pound retirement pot is comfortably in the top decile of UK retirement savings. It supports a "comfortable" retirement lifestyle by PLSA standards, retiring before State Pension age becomes feasible, and the planning challenge shifts from "is it enough" to "how to deploy it tax- efficiently".
The short answer
At a 4% withdrawal rate, £1 million supports £40,000 a year of investment income. Add the full State Pension of £11,500 and you have £51,500 a year before tax at State Pension age — comfortably above the PLSA "comfortable" single standard of £43,100, and approaching higher-rate tax territory if drawn entirely through taxable channels.
For early retirement, £1m supports a comfortable retirement from age 55–60 onwards, depending on the spending target. £40,000 a year from age 55 implies a 40-year retirement horizon — possible, but at the edge of what 4% rates have historically supported, especially at current valuations.
The tax problem at £1m
At this level, the 40% tax band becomes a planning constraint rather than a corner case. A retiree drawing £40,000 a year from a Self-Invested Personal Pension (SIPP), plus £11,500 State Pension, hits £51,500 of taxable income — £1,230 into the 40% band, costing an extra £246 in tax that wouldn't apply if held just below.
The 25% tax-free lump sum is capped at £268,275 — so on a £1m SIPP, you only get £250,000 tax-free, and the remaining £750,000 is fully taxable on withdrawal. ISAs and the tax-free band of any SIPP withdrawals (the personal allowance plus the lump sum) become the main levers.
Sequence-of-returns risk and longevity
On a 30-year horizon, 4% withdrawals from £1m have historically survived almost every test period. On a 35–40 year horizon — which a retiree at 55 implicitly chooses — the picture is less robust. A poor early decade combined with high fees and tax can take a £1m pot to under £400,000 by year 15. Once the pot is materially down, recovery becomes mathematically harder.
For early retirement on £1m, most planners would suggest either a more cautious 3.25–3.5% rate (£32,500–£35,000 a year), or flexible withdrawals where spending drops in poor market years and rises in good ones. Both significantly improve the probability of the pot lasting.
What changes the answer
- SIPP vs Individual Savings Account (ISA) split. A £1m pot evenly split between SIPP and ISA is dramatically more tax-efficient than the same pot all in one wrapper.
- Inheritance tax. Pensions become part of the estate for inheritance tax (IHT) purposes from April 2027. Couples with £1m+ in pensions have meaningful planning to do — drawing down ISAs and other taxable assets first is usually the starting point.
- Annuity at later ages. Buying a partial annuity at 75–80 with rising rates can guarantee a base level of income and reduce drawdown stress on the residual pot. See drawdown vs annuity.
- Couple status. £1m for a couple is comfortable retirement territory by any standard. £1m for a single retiree retiring at 55 is at the edge of "safe".
A worked example
A 60-year-old single retiree with £1m split 60% SIPP / 40% ISA targets £45,000 a year (well above PLSA "comfortable"). With the State Pension at 67, the seven-year bridge needs £315,000 in nominal terms. Drawing predominantly from ISA during the bridge keeps tax low; shifting towards SIPP from 67 onwards uses the personal allowance efficiently. Monte Carlo simulations on standard assumptions show ~85% probability of the pot supporting that spending to age 95.
Run your own numbers
At £1m the answers depend strongly on the wrapper mix, fees, and retirement age. The planner runs UK tax bands and Monte Carlo simulations on your specific numbers — far more informative than any single-rate rule of thumb.
