Will I have a £400k pension at 28?

Not on the minimum alone — but it's within reach~£286k by 67

On the median £31k salary for your age, paying just the auto-enrolment minimum of about £160 a month, you'd build roughly £286k by 67. To reach £400k you'd step up to about £245 a month (£85 more than the minimum) — or get there through pay rises, more generous employer schemes, or starting a little sooner. Even then, most of the pot is compounding, not saving harder.

To reach £400k by 67

Aim for this much in total monthly contributions (you + employer) — or close the gap with pay rises, a better employer scheme, or starting sooner.

You don’t save your way to £400k — you grow it

Of the £286k pot built by 67, about £84,880 is money you put in and roughly £201,230 is investment growth — 70p in every £1 comes from compounding, not a bigger salary.

Where these figures come from

The default salary, contribution and existing-pot figures are UK national medians, not a prediction about you — your own pay, employer scheme, other pensions and returns will differ. Change any of them in the live tester above. Growth of 5% a year above inflation is illustrative, and all amounts are in today’s money. This is a planning tool, not financial advice.

Frequently asked questions

Will I have a £400k pension at 28?

On the median £31k salary for your age, paying just the auto-enrolment minimum of about £160 a month, you'd build roughly £286k by 67. To reach £400k you'd step up to about £245 a month (£85 more than the minimum) — or get there through pay rises, more generous employer schemes, or starting a little sooner. Even then, most of the pot is compounding, not saving harder. The figures use national medians (not a promise about you): the ONS median full-time salary for ages 20–29 (£31k), the auto-enrolment minimum of about £160 a month (you + employer, 8% of qualifying earnings), the ONS median pot for someone your age who already saves (£10k), and 5% investment growth a year above inflation to age 67.

Do I need a high salary to get a £400k pension?

No. On the median £31k full-time salary for ages 20–29 (ONS), paying only the legal minimum, you'd build around £286k by 67. The reason is compounding: about 70% of the pot is investment growth rather than money you pay in. Starting earlier matters far more than earning more, because your early contributions have the longest to grow.

How much do I need to save each month for a £400k pension?

To reach £400k by 67 from age 28, you'd aim for about £245 a month in total contributions, versus the £160 auto-enrolment minimum on a median salary. A more generous employer scheme, salary sacrifice and pay rises help close that gap.

Is a £400k pension enough to retire on?

It depends on your spending and other income. A £400k pot plus the State Pension (about £11,502 a year from 67) might support a modest-to-comfortable retirement using the 4% guide. Use the free planner to test how long £400k would actually last at your target spending.

Are these numbers financial advice?

No. This is an illustrative worked example from a free planning tool using fixed assumptions (average pay, 5% real growth, pension access from 55). Your own pensions, employer, returns and career will change the result. Open the planner to run it with your real figures.
