Here's the opening and the core maths, in full — so you can see exactly how the Playbook reads before you buy. We follow one example throughout: Maya, 34, earning £58,000, spending about £30,000 a year, who wants to stop needing a salary in her early fifties.
2Your number — and why the withdrawal rate is the whole game
The headline rule of thumb is beautifully simple: your FIRE number is your annual spending times 25. Where does 25 come from? It's the flip side of a 4% withdrawal rate — draw 4% of a pot each year and the pot is 25 times your spending (100 ÷ 4 = 25). Choose a more cautious 3.5% and the multiple becomes ~29×; a bolder 4.5% and it drops to ~22×.
| Annual spending | ×25 (4%) | ×29 (3.5%) |
|---|---|---|
| £20,000 | £500,000 | £571,000 |
| £30,000 | £750,000 | £857,000 |
| £40,000 | £1,000,000 | £1,143,000 |
The single most important idea: the withdrawal rate is the entire game. Your number isn't really "how much do I need" — it's "how much can I safely take from my pot each year without running out?" Get that rate right and a smaller pot lasts forever…
Which brings us to the one lever that decides when you get there — and it isn't your salary or your stock picks…

How much do I need to retire early (my FIRE number)?
A common starting point is your annual spending × 25 — the flip side of a 4% withdrawal rate. Spend £30,000 a year and the rule of thumb is a £750,000 pot; a cautious 3.5% raises it to about £857,000. The state pension later reduces the pot your own savings must provide. The Playbook works this through with a running example.
Is the 4% rule safe for a UK early retirement?
The 4% rule comes from US research over a 30-year retirement. A UK early-retiree may need the money to last 45–50 years, so many planners use a more cautious 3.25%–3.5%, stay flexible with a "guardrails" approach, and allow for fees. The Playbook explains the rule honestly and how to build in a margin of safety.
Can I retire before I can access my pension?
Yes, but you must plan for it. A private pension can't normally be touched until 55 (rising to 57 from 6 April 2028) and a Lifetime ISA until 60 — so if you stop earlier you need a "bridge" funded from a Stocks & Shares ISA and cash. Building that bridge is the defining task of UK early retirement, and the Playbook walks through it.
Does this cover UK accounts like ISAs, LISAs and pensions?
Yes — it's a UK-specific guide, not another US-centric one. It covers the order to fill pensions, Lifetime ISAs and Stocks & Shares ISAs, their different access ages, tax-efficient withdrawal using the Personal Allowance and ISA, and the state pension and your National Insurance record.
Is this financial advice?
No. It's general information for the 2026/27 tax year to help you understand the mechanics of financial independence — not personal financial advice. Investments can fall as well as rise, examples are illustrative, and you should confirm current figures at gov.uk and take qualified, regulated advice before acting.
Can I get it for free?
Yes — every WealthR Playbook is included with WealthR Pro (£39.99/year), along with all the tools and future editions kept current each tax year. Or buy this Playbook on its own for £19.99.
Which tax year does it cover?
The 2026/27 UK tax year (England, Wales & NI), published July 2026. Figures are checked against gov.uk, and each year a fresh edition is published with a plain-English summary of what changed.
