A £400,000 pension pot is exceptional by UK standards — more than ten times the national average retirement pot of around £37,000. At the 4% withdrawal rate, it delivers £16,000 a year from the pot alone. Add the full new State Pension of £11,502 (£221.20/week in 2026/27) and total retirement income reaches £27,502 a year, or approximately £2,292 a month. That approaches the PLSA moderate single standard and significantly exceeds the minimum.
For couples, the figures improve considerably: if both partners have full State Pensions, combined household income with this pot can exceed £39,000 — well into moderate couple territory.
Income at a Glance: What £400,000 Provides in Retirement
| Income source | Annual | Monthly |
|---|---|---|
| 4% drawdown from £400,000 pot | £16,000 | £1,333 |
| Full new State Pension (2026/27) | £11,502 | £959 |
| Combined total | £27,502 | £2,292 |
| Annuity (£400k × 6.7%, level, age 65) | £26,800 | £2,233 |
| Annuity + State Pension | £38,302 | £3,192 |
The annuity option at £400,000 produces £38,302 combined with the State Pension — approaching the PLSA comfortable single standard of £43,100 and exceeding the moderate couple standard. For those who prefer certainty over flexibility, an annuity at this pot size is highly competitive.
What £16,000 a Year from Your Pot Means in Practice
Drawing £16,000 a year from your £400,000 pot adds £1,333 a month to your State Pension income. Total gross income is £27,502. After income tax of around £2,986 (20% on the £14,932 above the personal allowance), net income is approximately £24,516 a year (£2,043/month).
At this income level, you can afford a good-quality retirement: a family car, regular overseas holidays, dining out, hobbies, and most household comforts. This is not an austere retirement — it is one that most UK retirees would regard as comfortable.
Worked example: Helen is 67 and retires with a £400,000 SIPP and the full State Pension. She draws £16,000/year from her pot. Total gross income: £27,502. Personal allowance: £12,570. Taxable: £14,932. Tax at 20%: £2,986. Net income: £24,516/year (£2,043/month). She owns her home outright, so housing costs are confined to Council Tax and maintenance.
The Annuity Alternative
Buying a level annuity at 65 with a £400,000 pot generates approximately £26,800 a year for life at 6.7% annuity rates. Combined with the State Pension, total income is £38,302 a year — nearly £11,000 more than the drawdown approach. This figure sits between the PLSA moderate (£31,300) and comfortable (£43,100) single standards.
The income premium of an annuity is largest when the gap to the comfortable standard matters most. Many people at this pot size opt for a blended strategy: use £150,000–£200,000 to buy a guaranteed income of £10,000–£13,400/year and keep the remainder in drawdown. This combines income security with flexibility.

How Long Will £400,000 Last?
| Withdrawal rate | Annual withdrawal | Years until depleted (no investment growth) |
|---|---|---|
| 3% (conservative) | £12,000 | ~33 years |
| 4% (standard) | £16,000 | ~25 years |
| 5% (higher) | £20,000 | ~20 years |
With a balanced investment portfolio, the 4% rule is designed to support 30 years of inflation-adjusted withdrawals. From age 66, that is to 96 — a realistic planning horizon for anyone with average or above-average life expectancy. At 3%, the pot has an even higher probability of lasting a full retirement and may grow in real terms over time.
How £400,000 Compares to PLSA Retirement Living Standards
| PLSA standard | Single person | Couple |
|---|---|---|
| Minimum | £14,400 | £22,400 |
| Moderate | £31,300 | £43,100 |
| Comfortable | £43,100 | £59,000 |
At £27,502 combined income, you are £13,102 above the minimum and £3,798 below the moderate single standard. The gap to moderate is relatively small — equivalent to an additional £95 a week. Bridging it through ISA withdrawals, part-time income, or deferring the State Pension is very achievable.
For couples where both have State Pensions and one has a £400,000 pot, combined income is around £39,004 — approaching the couple comfortable standard (£43,100). With both partners having modest additional savings, reaching comfortable is realistic.

Maximising a £400,000 Pot in Retirement
1. Time your tax-free cash carefully. You can take up to £100,000 (25% of £400,000) as a tax-free lump sum. Rather than taking it all at once, consider drawing tax-free cash incrementally over several years alongside taxable drawdown to keep your annual tax bill low.
2. Draw from ISA savings first, before pension. If you have ISA savings alongside the pension, drawing from the ISA first (tax-free) can preserve the pension’s tax advantages and reduce your annual income tax bill.
3. Manage the higher rate threshold. Your total income of £27,502 is well within the basic rate band. But if you draw larger amounts in some years (for a holiday, car, or home improvement), watch the £50,270 threshold — pension withdrawals above this are taxed at 40%.
4. Consider a drawdown plus annuity blend. Use £150,000 to buy a guaranteed annuity income of around £10,050/year, keeping £250,000 in drawdown for flexibility. Combined with the State Pension, your guaranteed floor income is £21,552/year with discretionary drawdown on top.
5. Think about estate planning. Money remaining in a defined contribution pension on death passes outside the estate until April 2027. After that date, unspent pension pots will be included in the estate for inheritance tax purposes. Planning your drawdown strategy now, before the rules change, can make a significant difference.

Key Takeaway
A £400,000 pension pot delivers a genuinely comfortable retirement income of around £27,500 a year combined with the full State Pension. This is well above the PLSA minimum and close to the moderate standard. For couples with two State Pensions, combined income exceeds £39,000 — a comfortable household income by any UK standard. The main focus at this pot size shifts from “is it enough?” to “how do I draw it down tax-efficiently?”
