A substantial base, not a universal answer
£400,000 may support a workable retirement where spending is moderate and later guaranteed income reduces withdrawals. It may be less comfortable for an early retirement with high spending, housing costs or a long period before State Pension. The page exists because this is often the point where the answer is genuinely borderline and personal details matter.
Spending sensitivity matters
The Retirement Living Standards moderate benchmark for a single person in the site data is £32,700 a year, while the couple benchmark is £45,400. Those are context figures, not targets, but they show why spending level can change the result quickly.
A household spending £2,000 a month after tax is asking something very different from a household spending £4,000 a month.
Accessible assets can change the first years
If a large part of £400,000 is in ISA or cash, it can help before a pension becomes available. If nearly all of it is inside a pension and retirement starts before pension access, the early years may still need another bridge.
A fictional age-62 example
Someone retiring at 62 with £400,000, a State Pension starting at 67 and no mortgage may need private withdrawals to do more work for five years, then less once State Pension starts. That pattern is different from a level withdrawal every year, which is why a year-by-year calculator is more useful than a simple rule of thumb.
Common questions
Is £400,000 enough for early retirement?
It may be enough in some early-retirement plans, but the bridge before State Pension and the split between accessible savings and pension assets are crucial.
How does State Pension affect a £400,000 plan?
State Pension can reduce later withdrawals from private assets, which may make the same pot last longer after the start age.
