The FI Community: Resources We Love

Pete Adeney's foundational FIRE blog, written after he retired at 30 on a software engineer's salary. Blunt, funny, and still the best introduction to the 'badass' end of frugality.

Deep, spreadsheet-driven dives into the financial mechanics of early retirement — tax optimization, asset location, and the math behind the movement.

Home of the 'Stock Series,' the widely-cited explainer on why simple, low-cost index fund investing beats most alternatives for reaching financial independence.

The most rigorous public research on safe withdrawal rates. If you want the data behind the '4% rule' and where it breaks down, this is the source.

Paula Pant's blog and podcast on financial independence and real estate investing, built around the idea that you can afford anything, just not everything.

A family's day-to-day life after retiring in their 30s, mixing honest financial updates with travel stories — good evidence that early retirement is livable long-term.

A candid account of hitting a $1M portfolio goal and retiring, followed by years of unusually honest writing about what early retirement actually feels like.

Financial independence content aimed at high earners, especially physicians — student loans, tax strategy, and building wealth on a demanding schedule.

A wide-ranging personal finance blog covering real estate, investing, and career strategy, with a focus on building wealth well beyond a bare-bones FIRE number.

Deep dives on portfolio construction — lazy portfolios like the three-fund and All Weather, asset allocation by age, and head-to-head ETF comparisons, each argued from historical backtests rather than assertion. The place to go when you want to know why a portfolio is shaped the way it is. The site discloses Amazon affiliate links on book mentions.

Macro and investment research covering monetary systems, asset allocation, and why long-horizon returns look the way they do. The free newsletter carries most of the value; a paid membership adds deeper coverage. Broader and more macro than most FIRE writing, which is the point.

A long-running weekly podcast that crowdsources FI strategies from its own community — a good on-ramp if you'd rather listen than read.

Weekly interviews on financial independence and money mindset from the BiggerPockets network, with a natural lean toward real estate as a wealth-building tool.

A large, active Reddit community for discussing FIRE strategy, milestones, and the occasional reality check from people further down the path than you.

The investing community built around John Bogle's philosophy of low-cost, diversified index investing — deep, patient, and skeptical of anything flashy.

The book-length version of the Stock Series: a short, opinionated case for index funds, high savings rates, and ignoring most of what the financial industry sells you.

The book that predates and shaped the modern FIRE movement, reframing spending as hours of your life traded for money rather than just dollars spent.

One of the original retirement calculators, testing your plan against every historical U.S. market cycle back to 1871. No-frills, and still a community standard.

A more configurable historical-simulation retirement calculator, with support for variable spending strategies, Social Security, and multiple asset classes.

A visualization that runs your retirement plan against historical market returns alongside actuarial mortality data — a blunt way to see both money risk and time risk at once.

A free backtesting and portfolio analysis tool for comparing asset allocations against historical returns, risk, and drawdowns — useful once you're past the basic FI math.

A portfolio backtester for ETFs, stocks, funds and custom series. Compare several allocations over the same history, set rebalancing rules, model contributions or withdrawals, and inspect drawdowns, rolling returns, correlations and withdrawal outcomes. Free to use in the browser without an account, with usage limits and paid tiers beyond them.
