The dream of retiring early is becoming more popular, although for some of us 60 will be early! There are movements like FIRE (Financial Independence, Retire Early) helping people to stop working when they’re younger. But how realistic is early retirement? Can you retire early? And more importantly, what does your pension need to look like to make it happen?

Let’s break it down and see if it would work for you.

What does ‘early’ actually mean?

In the UK, the State Pension age is currently 66, rising to 67 and beyond for younger generations. Most workplace or private pensions are accessible from age 55 (rising to 57 in 2028).

So ‘early retirement’ typically means retiring before age 55, or simply retiring before the state supports kick in. That means relying on your own savings, investments, or pensions until other income sources become available.

What does your pension need to look like?

To retire early, your pension (or wider retirement pot) needs to tick three major boxes:

1. Can you retire early? Your pension needs to be big enough to last you for decades

If you retire at 55 and live to 85 or 90, that’s 30–35 years of living expenses you’ll need to cover.

A rough rule of thumb is the 25x rule—multiply your desired annual retirement income by 25. For example:

Want £25,000 a year?
You’d need a pot of around £625,000.

Of course, this assumes a balanced portfolio that continues to grow modestly during retirement.

Remember: This number is before state pension or other benefits kick in, so it may not need to cover your entire retirement on its own.

2. Accessible before the state pension age

If most of your money is locked in pensions that can’t be touched until 55 or 57, you’ll need other savings to bridge the gap if you plan to retire earlier.

Consider:

ISAs (especially Stocks & Shares ISAs) which are tax-free and accessible anytime.
General Investment Accounts (GIAs) which are flexible, though taxable.
Rental income or business income if you plan to keep earning passively.

Think of your retirement in phases:

Phase 1: From your retirement age to 55–57.
Phase 2: From 55/57 to State Pension age.
Phase 3: After State Pension kicks in.

Each phase needs funding in a slightly different way. You’ll need more within phase 1, and the least additional income/ savings in phase 3 when both private and state pensions will be paid out.

3. A well-managed and diversified could help you retire early

An early retirement plan isn’t just about how much you save—it’s about how your money works for you.

You’ll likely need to:

Invest for growth in your 30s/40s.
Transition gradually to income and stability in your 50s.
Balance risk and inflation protection throughout retirement.

A mix of pensions, ISAs, and investments can help you build a flexible strategy.

Tools and tips to help you plan

Use a pension calculator to estimate your future pot.
Check your State Pension forecast to see what you should be getting.
Track down old pensions from previous jobs—you may have more saved than you thought.
Talk to a financial adviser if early retirement is more than a pipe dream—you’ll need a plan

Early retirement pitfalls to avoid

Underestimating lifestyle costs – will your mortgage be gone? Will you travel more? Remember bills and expenses will continue to rise and won’t remain at the levels they are today.
Ignoring inflation – £30k today won’t stretch as far in 20 years so you’ll more to cover the same things.
Forgetting healthcare and long-term care needs.
Relying solely on one income source – flexibility is key and will help you reach your goals earlier.
