What Is FIRE?
FIRE (Financial Independence, Retire Early) is a movement focused on aggressive saving and investing to retire decades before the traditional age of 65. The core idea: save 50-70% of your income, invest in low-cost S&P 500 index funds, and build a portfolio 25x your annual expenses (the 4% rule). Many Americans achieve FIRE in their 30s or 40s using 401(k)s, Roth IRAs, and taxable brokerage accounts.
The 4% Rule Explained
The 4% rule, based on the Trinity Study, states that withdrawing 4% of your portfolio annually (adjusted for inflation) has a high probability of lasting 30+ years. For example, if you spend $4,000/month ($48,000/year), your FIRE number is $1,200,000. This calculator helps you see how long it will take to reach your number.

What Is Your FIRE Number for Financial Independence?
The FIRE (Financial Independence, Retire Early) movement is based on a simple idea: if you save enough money so that your annual returns cover your living expenses, you can stop working. The common guideline is the 4% rule — the amount you can withdraw annually from your portfolio without depleting it — based on the Trinity Study that examined portfolio performance over 30+ year periods.
Our FIRE calculator uses real returns (after inflation) — the default 5% reflects roughly 8% nominal returns minus 3% inflation. This means your FIRE number represents actual purchasing power, so you won't be surprised when today's expenses cost much more in 20 years.
How to Use the FIRE Number Calculator
Enter how much income you need per month to live without working, annual withdrawal rate (4% is recommended), monthly savings, current savings (including retirement accounts like 401(k), IRA, and brokerage accounts), and expected real annual return (5% after inflation is a conservative benchmark). The calculator will show your FIRE number and how many years it will take to reach it.

FIRE (Financial Independence, Retire Early) is a movement aimed at achieving financial independence as early as possible, so you no longer need to work to fund your living expenses.
The 4% rule, based on the Trinity Study, states that if you withdraw 4% of your investment portfolio annually, the money is expected to last at least 30 years. Therefore, your 'number' is the monthly income you need × 12 × 25.
Because inflation erodes the value of money. $6,000/month today will buy much less in 20 years. Real returns (after inflation) ensure your FIRE number represents actual purchasing power — so you won't be caught off guard when prices rise.
Social Security income and 401(k)/IRA withdrawals reduce the amount your portfolio needs to cover. Factor these into your monthly income needs. If you plan to retire before 59½, you'll need bridge funds for early years.
Lean FIRE — living frugally on $2,000-3,000/month. Fat FIRE — maintaining a high standard of living ($8,000+/month). Barista FIRE — partial independence with a low-stress job covering some expenses. Coast FIRE — stop saving because your portfolio will grow to your target by retirement age.
It depends on your lifestyle. At $5,000/month expenses with the 4% rule, you need $1,500,000. At $8,000/month — $2,400,000. Factor in healthcare costs before Medicare (age 65), which can add $500-1,000/month.
Sequence of returns risk — a major market crash in the first few years of retirement can permanently deplete your portfolio. Mitigate by keeping 2-3 years of expenses in cash/bonds and having flexible spending rules (e.g., withdraw less in down years).
