Frequently asked questions

How much will I have in my pension if I save £100/month from age 28?

If you save £100/month from age 28 to age 65 (37 years), your projected pension pot is £101,464 at 4% annual growth, £163,131 at 6%, or £271,640 at 8%. You will have contributed £44,400 in total; the rest is investment growth.

What income will £163,131 in a pension provide?

Using the 4% sustainable withdrawal rate — a common rule of thumb — £163,131 provides approximately £6,525/year (£544/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 £100/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 £100/month is enough, compare your projected income of £544/month to your expected retirement expenses, factoring in the State Pension and any other income sources.

How does employer matching affect my pension at £100/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 £100/month will increase your final pot proportionally.
