Guide
The best money and early-retirement books, blogs and tools
There are a thousand "best money books" lists online, most padded with affiliate links and books the writer never finished. This isn't one of them. Below are the books, sites and tools that actually helped, with no affiliate links and no kickbacks, so nothing is here for any reason other than that it earns its place. Take what's useful, skip what isn't.
Books
The Psychology of Money — Morgan Housel. The one I'd hand anyone starting out. Not about spreadsheets, about behaviour, which is what actually decides whether you get rich and stay that way. Short, wise, no jargon.
Die With Zero — Bill Perkins. The antidote to over-saving: dying with a fat pile of unspent money is a failure, not a trophy. If you read one book on why to retire early, this is it. Frankly, it's the argument behind this whole tool.
Your Money or Your Life — Vicki Robin & Joe Dominguez. The book that started the movement. Its idea that money is just your life energy in another form reframes every spending decision. Dated in places, timeless where it counts.
The Simple Path to Wealth — J.L. Collins. The clearest explanation of index-fund investing ever written. If investing intimidates you, start here: low-cost index funds, stay the course, ignore the noise.
The Little Book of Common Sense Investing — John Bogle. From the man who invented the index fund. The backbone for why cheap, boring investing beats almost everyone trying to be clever. Pair it with Collins.
Quit Like a Millionaire — Kristy Shen & Bryce Leung. The most practical book on the bit everyone gets wrong: not saving, but drawing down once you've stopped. Math-based, no-nonsense, and free of "follow your passion" fluff.
The Richest Man in Babylon — George Clason. Hundred-year-old parables that are still true: pay yourself first, live below your means, make your money work. Corny delivery, sound fundamentals.
How to Retire — Christine Benz. Most retirement books are about the money. This one is about the harder question: what you'll actually do with the freedom. The half nobody plans for, and the half that trips people up.
Rich Dad Poor Dad — Robert Kiyosaki. The book that makes assets-versus-liabilities click, and it hammers home the importance of building passive income: owning things that pay you rather than cost you. That single idea has started a lot of people off. Take it as a mindset primer rather than a how-to; the specific tactics are light, but the spark is real.
Websites
Monevator. The best UK site on investing and financial independence, full stop. Passive investing and early-retirement thinking written for grown-ups. Start here if you're in the UK.
Mr Money Mustache. The blog that dragged early retirement into the mainstream. Pete Adeney retired at 30 and writes with a boot-to-the-backside style about spending less and buying your freedom. Skim the philosophy, ignore the occasional smugness.
Early Retirement Now. If you want the real answer on the 4% rule, Karsten's Safe Withdrawal Rate series is the most rigorous work anywhere. Heavy going, worth it, and exactly why this tool projects your whole life instead of applying a rule of thumb.
Bogleheads. The forum and wiki built on Jack Bogle's philosophy. Unglamorous, evidence-based, and one of the few money communities online worth trusting. The wiki alone is a free education.
The Mad Fientist. For when you're past the basics: the tax and drawdown tactics that shave years off your timeline. Deep, specific, genuinely clever.
Epic Retirement. Bec Wilson's antidote to money-only planning. Her six pillars, time, money, health, happiness, travel and home, are a reminder that the number is only half the job; what you actually do with the freedom is the other half. There's a free newsletter (with a separate UK edition), a podcast, and a genuinely good book. It skews to the life side, which is exactly why it belongs on a list this heavy with spreadsheets.
For community and reality checks, the r/FIRE and r/FIREUK subreddits are worth a lurk, real numbers from real people, with the usual internet caveats.
Tools
Fewer than the reading lists suggest you need. In rough order of usefulness:
- Know your spending first. It's the biggest input to any retirement number, and most people guess it wrong. A budgeting app like Emma pulls your accounts together so you can see what you actually spend, not what you think you spend.
- Track your net worth. A tracker like Aureli (UK-built) shows the whole picture, pensions, property, investments and debts, in one place. Useful, but a snapshot: it tells you where you are, not when you can stop.
- Project the whole life, not a snapshot. This is the gap ETQ fills: your real cash flow and net worth, year by year to the end of life, giving you an age rather than a number. Others do versions of it, Isaac models UK pensions and tax in fine detail, and cFIREsim and Engaging Data's FIRE calculator run thousands of Monte-Carlo market paths. ETQ deliberately goes deterministic and full-life instead (the reasoning is in the how-much guide). Use whichever earns your trust; the point is to project, not to guess.
- Spreadsheets. Never underestimate them. ETQ's engine started life as one. If you enjoy building your own, do; if you'd rather not lose a weekend to formulas, that's what the tool is for.
Then do the thing the books can't
Reading is the easy part. At some point you have to put your own numbers down and see when work becomes optional, which is the whole reason this tool exists. Start with the guide on how much you really need, or go straight to the estimate.
