Retirement feels distant in your 20s — but that distance is your greatest financial asset. Thanks to compound interest, early money grows exponentially. Building on our pension basics.
The Power of Starting Early

Workplace Pension: Free Money
Under auto-enrolment, you contribute 5% and your employer adds 3%. That's an instant 60% return before any investment growth. The minimum total is 8% of qualifying earnings. Many employers offer to match higher contributions — always take the maximum match.
How Much Do You Need for Retirement?
A common rule of thumb: aim for 10-15x your desired annual retirement income as a pension pot. If you want £25,000/year, target £250,000-375,000 (plus State Pension). Use online pension calculators to get a personalised figure. The earlier you start, the lower your required monthly contribution.
Getting Started in Your 20s and 30s
First, opt into your workplace pension and take the full employer match. Second, open a Lifetime ISA if you're under 40 — the 25% government bonus is free money. Third, even small additional contributions matter. Use SYM to build the saving habit, then redirect savings to retirement accounts as your income grows.
Frequently Asked Questions
Can I rely on the State Pension?
The full new State Pension is £241.30 a week in 2026/27 — unlikely to fund a comfortable retirement alone. Treat it as a foundation and build private pension savings on top.
Is it too late to start in my 40s?
Never too late — you still have 20+ years of growth. You'll need to contribute more monthly than if you'd started earlier, but compound interest still works in your favour.
Should I save or pay off my mortgage first?
Ideally both. Always take your full employer pension match first (it's free money). Beyond that, if your mortgage rate exceeds expected investment returns, consider overpaying the mortgage.
