FIRE

FIRE stands for Financial Independence, Retire Early. The practice: save enough that investment returns cover living costs without a paycheck, typically 25 to 30 times annual expenses under a 4% or lower withdrawal rate. A $40,000 lifestyle targets $1 million to $1.2 million. The movement's core arithmetic is the savings rate: at 50% of income saved, the timeline compresses to roughly 17 years; at 70%, under 10.

Variants trade comfort against timeline: Lean FIRE on minimal spending, Fat FIRE on a comfortable budget, Barista FIRE with part-time income covering the gap, and Coast FIRE where enough is saved that compounding alone finishes the job. In the US, the account structure matters: 401(k) and IRA limits of $24,500 and $7,500 in 2026 push most savers into taxable brokerages for the early-access years. The penalty-free bridges are 72(t) SEPP and the Rule of 55.

The timeline is a function of the savings rate, because saving more does double duty: it builds the portfolio and shrinks the spending it must support. At a 6% real return, saving 25% of income reaches financial independence in roughly 29 years; saving 50% reaches it in roughly 16; saving 70% in under 10. The accumulation runs on index funds and tax-advantaged accounts first, then taxable brokerage overflow once the 401(k) and IRA limits are maxed. The order of operations matters more than the market: accounts first, conversions annually, and the taxable bridge last.

The withdrawal phase needs an access plan, because most of the money is locked until 59½. The bridges are mechanical. They are 72(t) SEPP schedules from an IRA, the Rule of 55 from a separating employer's 401(k), and the Roth conversion ladder, where annual conversions sit five years and then withdraw tax and penalty free. Healthcare is the unfunded liability: pre-65 coverage through the ACA marketplace can run $12,000 to $18,000 a year for a couple before subsidies. Subsidy cliffs change the effective marginal rate on every dollar of realized income.

FIRE's real contribution is not the early retirement; it is the clarity of the arithmetic. Every dollar of spending cut removes $25 to $30 from the target, which makes lifestyle decisions the highest-leverage moves in the plan, ahead of any fund selection. The savings rate is the only variable the saver fully controls.

I watched a colleague named Brent (yes, that Brent) declare FIRE at 50 with a $600,000 portfolio against $60,000 of spending, a 10x rather than a 25x, because a good market year felt like a system. He was back at a desk within two years. The market did not fail him; the multiple did.

The highest-leverage thing most Americans chasing FIRE can do is fix the spending number first, then raise the savings rate before optimizing anything else. Size the target with the investment goal calculator and pressure-test the withdrawal plan with the SWP calculator. The market return is the one variable nobody controls; the savings rate is the other one.
