FIRE

Also called financial independence retire early · leanFIRE · coastFIRE · chubbyFIRE · fire number

Community talk. May contain inaccuracies. Not financial, tax, legal, or investment advice. No return or outcome is promised.

FIRE means financial independence, retire early: building enough resources that paid work becomes optional. A FIRE number estimates the investments needed to fund that life. It depends on spending, other income and withdrawal assumptions, rather than a universal dollar target.

Fidelity · 2025

01

How a FIRE number is built

Start with the life after work. Review a year of bills, then estimate housing, food, transport, healthcare, taxes, travel and replacements after leaving work. Retirement contributions are separate from retirement spending. A bare-bones working budget may not describe the life being funded.

Fidelity · 2025

Divide the annual spending gap by a withdrawal assumption. If investments must supply $60,000 a year, including taxes and healthcare, dividing by 0.04 gives $1.5 million; dividing by 0.03 gives $2 million. These are arithmetic examples, not recommended balances. The rate describes the first withdrawal relative to the starting portfolio; an inflation-adjusted plan then adjusts dollar spending, rather than always taking that percentage of the latest balance.

Fidelity · 2025

Put changing income and expenses on a timeline. Subtract income available in each year from that year's spending. A later pension cannot pay today's bills. Model mortgage or college costs for their remaining years. Count home equity through a specific access plan, such as selling, rather than automatically including the home's value in the investment balance.

FIRECalc · 2026 data update

A future pension leaves an earlier spending gap. Illustration: a household needs $48,000 a year, with an $18,000 pension beginning five years after retirement. The portfolio initially needs to cover $48,000; afterward the gap is $30,000, before any further changes. Dividing only $30,000 by a withdrawal assumption leaves out the first five years. Their extra $18,000 a year totals $90,000 before inflation or investment changes, but adding $90,000 to a long-term target is still only a rough sketch, not a tested retirement plan.

Illustration · context: FIRECalc
The pension starts after five full years

The fictional household spends $48,000 each year. Its $18,000 annual pension begins only after five full retirement years.

  • Portfolio-funded gap
  • Pension
Each of years 1–5: $48,000 gap + $0 pension
Each year from year 6: $30,000 gap + $18,000 pension

The early gap is $18,000 larger every year. Across five years, that difference totals $90,000 before inflation, investment changes or other spending changes.

Bars show one year of spending, not portfolio size. Adding $90,000 to a long-term target is only a rough sketch, not a tested retirement plan.

Saving now and withdrawing later are different rates. The savings rate is the share of income being put away; the withdrawal rate concerns spending from investments. Building the portfolio involves income, spending and regular investing. Employer benefits and available retirement accounts can help, while a taxable account can provide another source of accessible money.

Fidelity · 2025

Test the target against more than one future. A calculator can vary retirement length, investment mix, fees, later income and spending. Include a bad early market and a higher-cost case. FIRECalc replays historical return sequences; its results describe past scenarios, not the probability that a household's future will succeed.

FIRECalc · 2026 data update

02

Why people use it

A target connects today's saving with future choices. Financial independence can support a job change, fewer working hours or early retirement. Reaching a goal does not require leaving work that remains useful or enjoyable.

Fidelity · 2025

Different budgets reveal different options. Comparing a modest lifestyle with a more expensive one shows which costs move the target. A dated spending plan is more useful than comparing one balance with a stranger's net worth.

FIRECalc · 2026 data update

03

Good to know

A withdrawal estimate is not a guaranteed paycheck. Sequence risk means poor returns early in retirement, combined with withdrawals, can leave less money to recover later. A 40–50-year retirement needs that longer horizon tested. A strong market year alone does not establish readiness to stop working.

FIRECalc · 2026 data update

Early access has U.S. tax rules. Before 59½, retirement-account withdrawals generally face an extra 10% federal tax unless an exception applies. Ordinary income tax and plan restrictions may also apply.

IRS · checked September 2026

Leaving work also changes health coverage. Losing job-based insurance can open Marketplace enrollment; financial assistance depends on eligibility, income and household size. Coverage needs its own estimate before quitting, including premiums and out-of-pocket costs—not a forum poster's premium guess.

From community discussion

Temporary bills changed a $4 million estimate to $2.94 million. A 2017 forum poster separated $450,000 for 15 years of healthcare (ages 50–65) at $30,000 annually, about $245,000 of mortgage balance and $120,000 for college. Their alternative added that $815,000 pot to $2.125 million for ongoing spending, instead of applying 4% to every initial expense forever. Taxes were excluded. Replies favored separating time periods but noted omitted earnings on the pot and uncertainty ten years ahead. These were household assumptions, not current healthcare prices or a proven plan.

Community · Mr. Money Mustache forum

Covering $45,000 of spending did not settle the desired lifestyle. An r/Fire poster said their investments covered current expenses but wondered whether a future budget should be twice as large. Replies differed: add specific travel and healthcare costs, build several spending scenarios, or recognize that continually raising the target can prolong work. One retiree reported spending $105,000 in 2025 after originally imagining $60,000, helped by portfolio growth that is not assured for others.

Community · Reddit

CoastFIRE leaves today's bills to be funded. Community vocabulary uses Lean for lower spending and Chubby for more room in the budget. Coast means existing investments are expected to grow toward a later retirement goal without new contributions. It still assumes a retirement date and growth path; it does not mean the portfolio already covers current living costs.

Community

A career-break plan drew both encouragement and doubts. An r/coastFIRE poster reported roughly $975,000 of assets, $60,000 annual spending and a planned $30,000 six-month break, followed by lower-paid work. Replies questioned cash-heavy investments, uncertain replacement income and health coverage; others supported coasting. The discussion shows why the balance alone cannot establish that work is optional. It reports a plan, not a completed retirement outcome.

Community · Reddit

High savings rates can hide very different circumstances. Lean-room reports include 40–70% savings-rate talk, not a required rate or measured norm. They describe years of tight spending before a one-income or no-job experiment. Lifestyle creep can absorb the savings supporting the goal. Salaries, families and cities make direct comparisons misleading.

Community

Simple portfolios and a written budget mattered more than the label. Reports favor index funds, the workplace match and available retirement accounts, while debating healthcare and long retirements. SWR means safe withdrawal rate in those conversations: a planning estimate, despite the reassuring name. The recurring practical concern is whether the household's money can actually fund its spending.

A FIRE number is an estimate of the investment assets needed to support financial independence or early retirement, based on spending, other income and a chosen withdrawal assumption.
why Line
The target moves when housing, healthcare, family needs or work plans change. People also disagree about which assets can actually fund spending and how much flexibility they want.

what People Say
  • The job: enough invested that a job is a choice. [community]
  • r/financialindependence, r/LeanFire, r/ChubbyFIRE are the rooms. [community]
  • CoastFIRE means the pile can grow without new contributions. [community]
  • Why skeptics groan: sequence risk, health insurance, kids, and a 50-year retirement. [community]
  • The target and the withdrawal assumption connect: the FIRE number estimates the assets needed; the 4% discussion tests one way those assets might fund spending. The percentage is an assumption, not a guarantee. [community]
  • FIRE describes a financial goal: it is not a particular security or asset class. Different portfolios and spending assumptions can produce different paths and risks. [community]
how People Run It
  • They compare savings with the desired lifestyle: the amount being saved now and the future spending target determine how much remains to be funded. Community labels do not replace those numbers. [community]
  • They do the match and tax-advantaged accounts first — those cards still exist. [community]
  • They do not quit on a green year without a healthcare plan. [community]
amounts People Use
  • Savings-rate talk: often 40–70% in Lean rooms, lower in Chubby. [community]
  • Withdrawal-rate assumption: “SWR” means safe withdrawal rate in these discussions. The label describes a planning estimate tested against assumptions, not a promise that money cannot run out. [community]
how People Keep It
  • A boring portfolio and a written spend. [community]
  • It fades when: lifestyle creep eats the rate. [community]
how It Feels
  • Early years: tight. Later: optional. [community]
how Long People Run It
  • Years of saving, then a one-income or no-job experiment. [community]
deep Dive
  • The pieces do different jobs: an employer match and retirement accounts concern saving; a taxable brokerage concerns another place to invest; the withdrawal-rate assumption translates a future spending gap into a rough portfolio target. None of those choices alone establishes readiness to stop working. [community]

        A mortgage discussion in r/Fire separates total wealth from the cash a retirement plan must produce each year. Participants modeled the mortgage ending, health-coverage changes and Social Security starting on different dates. That is why multiplying one year’s spending by a single number is a rough estimate: the spending gap itself can change. The discussion offers several models, not a consensus that any one target guarantees retirement.
        sources
      guide
      what
      • FIRE is an internet name for saving and investing until paid work is optional. Lean, Coast, and Chubby are community labels for different spending levels. They are not IRS categories and not a pension.
      • A projected withdrawal rate is a model of how much a portfolio might support. It is not a paycheck, not a guarantee, and not a reason to quit on a strong market year. Healthcare, a long retirement, and a bad sequence of returns sit outside a single percentage.
      • The federal securities regulator's investor.gov retirement material is about saving and investing for retirement in general. It does not certify a FIRE number. The number is personal: spending, savings already invested, and what still has to be funded.
      how
      • Write the annual spending that the optional-work life would actually require, including housing, healthcare, and taxes. Separately write what is being saved now and what is already invested. The gap between those figures is the funding problem. A community label does not replace it.
      • Use the workplace match and the tax-advantaged accounts that are available before inventing a taxable hero number. Those accounts have their own limits and rules. A FIRE spreadsheet that ignores the match is leaving compensation behind.
      • Treat any withdrawal percentage as a scenario. Run a lower spending case and a case with a bad early market. Do not quit a job because one green year made the spreadsheet look finished, and do not quit without a healthcare plan for the years before Medicare.
      • Recalculate when spending, family, or the portfolio changes. A number computed once and tattooed is not a plan.
      understand
      • The mechanism people are reaching for is a portfolio large enough, relative to spending, that work becomes a choice. The arithmetic is spending and savings. The risk is treating a back-tested rate as a contract.
      • The miss is a lifestyle label with no spending figure, or a plan that skips healthcare. Another miss is comparing a net-worth screenshot with a stranger whose mortgage, pension, and city are different.
      • Community notes argue about Lean and Chubby and about safe withdrawal rates. Those are arguments. The household's spending and the account statements are the inputs.
