Can I retire on £40,000 a year in the UK?
£40,000 a year sits between the PLSA "moderate" and "comfortable" single-retirement standards. It supports occasional foreign travel, a more recent car, and meaningful discretionary spending — but the tax bill begins to bite, and the pot required is correspondingly larger.
The short answer
With the full new State Pension covering £11,500, your investments need to deliver around £28,500 a year before tax. Using a 4% withdrawal rate, that implies a pot of around £710,000; on a 3.5% basis, around £820,000. A defensible single planning figure is £750,000–£850,000 at State Pension age.
For a couple, two State Pensions cover £23,000 of the £40,000, and £40,000 is well below the PLSA "comfortable" couples figure of around £59,000. A couple targeting £40,000 jointly therefore needs a far smaller pot than a single person at the same income.
The tax cost above £40,000
£40,000 a year of taxable retirement income produces a substantially higher tax bill than £30,000. After the £12,570 personal allowance, the next £37,700 is taxed at 20% — but at £40,000 you are still in basic rate for now (the 40% rate kicks in at £50,270). Tax on £27,430 of taxable income is around £5,486 a year, leaving net spending of roughly £34,500.
Drawing some income from an Individual Savings Account (ISA) reduces taxable income and improves the net figure. A 50/50 split between Self-Invested Personal Pension (SIPP)/State Pension and ISA could lift net spending towards £37,000 on the same gross.
What £40,000 a year covers
For a single retiree, £40,000 sits comfortably above the PLSA "moderate" single standard of £31,300. Practical implications: two foreign holidays a year, a more recent car replaced every five years, a generous household budget, and healthy contingency for one-off expenses such as roof repairs, health costs, or supporting family.
What changes the answer
- SIPP vs ISA mix. The bigger your SIPP, the more tax you pay on retirement income at this level. ISAs and the tax-free 25% lump sum are particularly valuable when the headline withdrawal is high.
- Drawdown vs annuity. Some retirees buy a partial annuity to lock in part of the £40,000 as guaranteed inflation-linked income. See drawdown vs annuity.
- Sequence risk. A 4% withdrawal rate has historically survived most 30-year periods, but at £40,000 gross with a £750,000 pot you are close to that limit. A Monte Carlo simulation matters here.
- Fees. A 0.5% fee on £800k is £4,000 a year — material when your withdrawal headroom is in the mid-£20ks after State Pension.
A worked example
A 65-year-old single retiree wants £40,000 a year, with State Pension starting at 67. For two years, the investment pot must deliver £40,000; from 67 onwards, £28,500. The blended pot indicated at 65 is roughly £800,000–£900,000 in today's money. A healthier ISA balance (say 40% of the pot) reduces the tax cost and shifts the lower bound towards £750,000.
Run your own numbers
£40,000 is a level where the SIPP/ISA mix, fees and tax choices materially change the answer. The planner runs UK tax bands explicitly and shows the Monte Carlo distribution of outcomes, which is more useful at this withdrawal level than any single rule of thumb.
