On its own terms, a £750,000 pot gives you £187,500 free of tax and £562,500 taxed as income. Alongside the full State Pension it covers the gap to Pensions UK's moderate standard for one person for over 37 years, before any investment growth or loss. Whether that is enough depends on when you stop work and what else you have.
State Pension: gov.uk, 2026/27 weekly rate of £241.30, multiplied by 52. Retirement Living Standards: Pensions UK, published 3 June 2026, single person, outside London, assuming the home is owned. Tax: gov.uk, 2026/27. All checked 2 October 2026. The sums assume no investment growth and no losses.
Pensions UK's standards are yearly spending for one person outside London who owns their home. Two people need £22,500, £45,400 or £62,700. The years above are the pot divided by the gap, so they leave out tax, growth, losses and inflation, and they assume you receive the full State Pension.
A pot this size can pay well beyond the comfortable standard, which brings the 40% band into play. Total income above £50,270 is taxed at 40% in England, Wales and Northern Ireland.
Income above £100,000 loses £1 of personal allowance for every £2 over, so a single large withdrawal can be taxed at an effective 60% on part of it. Spreading income, and using a partner's allowances, matters more here than at smaller pot sizes.
Between £100,000 and £125,140 of income, part of every withdrawal is taxed at an effective 60%.
Before any growth, £750,000 covers the gap between the full State Pension and Pensions UK's comfortable standard for about 22.8 years.
Normally 25%, which is £187,500. The tax-free part across all your pensions is capped at £268,275 unless you hold a protection.
Annuity income depends on your age, health, where you live and rates on the day, and differs between insurers. A quote on your own details is the only reliable figure.
At this size, the way income is spread between years and between partners decides the tax.
