Is a £100,000 pension pot enough to retire?

On its own terms, a £100,000 pot gives you £25,000 free of tax and £75,000 taxed as income. Alongside the full State Pension it covers the gap to Pensions UK's moderate standard for one person for about 5.0 years, before any investment growth or loss. Whether that is enough depends on when you stop work and what else you have.

What the pot is made of

£25,000normally available free of tax, as 25% of the pot

£75,000taxed as income when you take it

£12,548a year from the full new State Pension, roughly

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.

How long it lasts at each standard

To reach the minimum standard: £13,900 a year. The full State Pension covers £12,548, leaving £1,352 to find. A £100,000 pot pays that for longer than any retirement is likely to last.
To reach the moderate standard: £32,700 a year, leaving £20,152 after the State Pension. The pot pays that for about 5.0 years.
To reach the comfortable standard: £45,400 a year, leaving £32,852 to find. The pot pays that for about 3.0 years.

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.

Taking it all as cash

In 2025/26, 45.8% of pension pots accessed for the first time were cashed in full, according to the FCA.

Cashing in this pot adds three quarters of it, £75,000, to your income in the year you take it. With the full State Pension already using your personal allowance, about half of that £75,000 would be taxed at 40%.

Spread over several tax years, the same £75,000 can be taken mostly at 20%.

What changes the answer

When you stop work. The State Pension starts at 66, rising in stages to 67 for people born from 6 April 1960, and the years before it have to be paid for entirely from savings.
Whether you get the full State Pension. It depends on your National Insurance record. Check your forecast at gov.uk/check-state-pension.
Where you live. In Scotland the tax bands differ, with rates from 19% to 48%.
What else you have, such as a partner's pension, ISAs, a final salary pension or a home you might sell.
How the money is taken. An annuity pays a guaranteed income for life, priced on your age, health and current rates. Drawdown keeps the money invested, with the risk that it falls or runs out.

Cashing in a pot this size in one tax year can cost you thousands of pounds more in tax than taking it over several.
