Quick answer: £500,000 can fund retirement at 55 if you spend around £20,000–£25,000 a year and can bridge the 12 years to State Pension at 67. Using the 4% rule, £500k gives ~£20,000/year — a moderate lifestyle. After State Pension kicks in, your effective income rises to ~£32,000 for a single person.
The 4% rule applied
£500,000 × 4% = £20,000/year (inflation-adjusted) for ~30 years. Some UK planners use 3.5% (£17,500) for extra safety given longer retirements and higher fees.
The State Pension gap
| Phase | Income |
|---|---|
| 55–67 (drawdown only) | £20,000 |
| 67+ (single) | £20,000 + £11,973 = £31,973 |
The 12-year gap is the constrained part; after 67 your income jumps ~60% with no extra effort.
Couple with £500k combined
Tighter pre-67 (£20k between two), but with two full State Pensions it reaches ~£44,000 from 67.
Make it work
- Have your mortgage cleared by 55
- Use UFPLS for tax-efficient withdrawals (~£500/yr tax vs ~£1,500)
- Hold 1–3 years' cash buffer against sequence-of-returns risk
- Part-time work in your 50s transforms the maths

Frequently asked questions
Yes, if your annual spending is around £20-25k and you can wait for State Pension at 67. Using the 4% rule, £500k provides £20,000/year, enough for a moderate UK lifestyle but not a comfortable one without State Pension topping up after 67.
Using the 4% safe withdrawal rate, £500k gives £20,000/year in real (inflation-adjusted) terms for ~30 years. An annuity at 65 would give about £36,000/year level, but you'd lose the capital.
It's tighter for a couple. £20,000/year between two people supports a basic lifestyle. With both eventually getting State Pension (£23,946 combined at 67), the picture improves substantially after 67.
At a 4% withdrawal rate (£20,000/year + inflation), historical data suggests £500k lasts 30+ years with high probability. At higher withdrawal rates, less. Sequence-of-returns risk in the first decade matters most.
From 55 to 67 is 12 years without State Pension. You need to fund the full £20-25k/year from your £500k pot during this gap, then State Pension provides ~£12k/year top-up from 67.
Only if you have a use for it (mortgage clearance, one-off purchase). Otherwise leaving the full £500k invested usually gives better long-term outcomes than taking £125k as cash and earning low interest.
