Will I have a £300k pension at 25?

Yes — time is on your sideOn track for £302k by 67

Yes. Starting from the £5k an average saver your age already has, and paying in the auto-enrolment minimum of about £160 a month on the median £31k full-time salary for your age, you're on track for roughly £302k by 67 — you'd pass £300k around age 66. About 71% of that is investment growth, not money you save — you don't need a big income, you need time.

You don’t save your way to £300k — you grow it

Of the £302k pot built by 67, about £86,040 is money you put in and roughly £215,518 is investment growth — 71p 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 £300k pension at 25?

Yes. Starting from the £5k an average saver your age already has, and paying in the auto-enrolment minimum of about £160 a month on the median £31k full-time salary for your age, you're on track for roughly £302k by 67 — you'd pass £300k around age 66. About 71% of that is investment growth, not money you save — you don't need a big income, you need time. 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 (£5k), and 5% investment growth a year above inflation to age 67.

Do I need a high salary to get a £300k pension?

No. On the median £31k full-time salary for ages 20–29 (ONS), paying only the legal minimum, you'd build around £302k by 67, past £300k. The reason is compounding: about 71% 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 £300k pension?

On these assumptions the auto-enrolment minimum of about £160 a month already gets there by 67. Paying in a little more, or starting sooner, would reach £300k earlier or leave headroom.

Is a £300k pension enough to retire on?

It depends on your spending and other income. A £300k 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 £300k 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.
