Can I retire with £750,000?
£750,000 sits in the middle ground between "comfortable retirement at State Pension age" and "early-retirement territory". It is the level where the Self-Invested Personal Pension (SIPP)/Individual Savings Account (ISA) mix, the sustainable withdrawal rate and the bridge to State Pension age all start to matter materially.
The short answer
At State Pension age, £750,000 supports a sustainable additional income of around £26,000–£30,000 a year at a 3.5–4% withdrawal rate. Combined with the full State Pension of £11,500, total gross income lands in the £37,500–£41,500 range — comfortably above "moderate" and approaching "comfortable" by PLSA standards.
For early retirement, £750,000 supports something close to £30,000 a year from age 60, including the State Pension once it arrives. That is a sustainable PLSA "moderate" lifestyle with seven years of bridge funding.
£750k at age 60 — a typical FIRE-adjacent target
For a 60-year-old retiring with £750,000 split roughly 50/50 between SIPP and ISA, a sustainable spending rate is around £30,000 a year (gross), comfortably PLSA "moderate". The seven-year bridge to State Pension age 67 takes about £210,000 of the pot in nominal terms; the remaining pot must then carry a £19,000-a-year top-up over State Pension for the balance of the retirement. Monte Carlo simulations show 85–90% probability of success on this profile, depending on assumptions.
The 40% tax band watch-out
£750k withdrawn carelessly can push a retiree into the 40% band. Drawing £40,000 a year all from a SIPP plus a full State Pension produces a gross of £51,500 — over the £50,270 higher-rate threshold. Rebalancing some of the £40,000 into ISA withdrawals avoids that.
For couples splitting income, the headroom is much larger: two personal allowances and two basic-rate bands together cover up to £100,540 of taxable household income before any 40% tax applies. Pension consolidation strategies often aim to spread future drawdown evenly.
What changes the answer
- The 25% tax-free lump sum. Up to £187,500 of the pot is tax-free at withdrawal. Taking it carefully — not necessarily all at once — is one of the higher-leverage decisions at this level.
- Stress test for crashes. A poor early decade reduces what £750k can support. A 4% rate is on the edge for a 35-year horizon at recent valuation levels — consider 3.5% as a planning rate.
- Inheritance position. £750k is large enough that estate-planning considerations matter, especially with the 2027 changes to pension inheritance tax (IHT) treatment.
- Couple vs single. £750k for a couple easily supports a comfortable joint retirement; for a single retiree it is "moderate-comfortable" rather than fully "comfortable".
A worked example
A 62-year-old single retiree with £750,000 (50% SIPP, 50% ISA) targets £30,000 a year. From 62 to 67, the full £30,000 comes from investments. From 67 onwards, State Pension provides £11,500, and £18,500 comes from investments. Drawing mostly from ISA before 67 (tax-free) and shifting towards SIPP after preserves more of the SIPP for tax-efficient use once the personal allowance is "used" by State Pension.
On a 3.75% effective withdrawal rate, the indicated probability of the pot lasting to age 95 is roughly 88% on standard return assumptions. Run a Monte Carlo simulation to stress-test against poor early years.
Run your own numbers
£750,000 is the level at which the planner becomes most useful — small changes to fees, the SIPP/ISA split, or the assumed return shift the indicated probability of success substantially.
