Frequently asked questions

How much will I have in my pension if I save £400/month from age 40?

If you save £400/month from age 40 to age 65 (25 years), your projected pension pot is £205,652 at 4% annual growth, £277,198 at 6%, or £380,411 at 8%. You will have contributed £120,000 in total; the rest is investment growth.

What income will £277,198 in a pension provide?

Using the 4% sustainable withdrawal rate — a common rule of thumb — £277,198 provides approximately £11,088/year (£924/month) in retirement income. This does not include the State Pension (currently £11,502/year full new State Pension in 2025-26), which would supplement your private pension income.

Is £400/month enough for a pension?

The Pensions and Lifetime Savings Association defines a 'moderate' retirement standard as around £31,300/year for a single person. To assess whether £400/month is enough, compare your projected income of £924/month to your expected retirement expenses, factoring in the State Pension and any other income sources.

How does employer matching affect my pension at £400/month?

The projections above show personal contributions only. If your employer matches contributions — typically 3–6% of salary — your total monthly pension saving could be significantly higher. For auto-enrolment, the minimum total is 8% of qualifying earnings (3% employer + 5% employee). Adding your employer contribution to £400/month will increase your final pot proportionally.
