Read the full answer — method, rates and figures
Quick answer: The FIRE number formula is annual expenses ÷ safe withdrawal rate. The 4% Rule (Bengen 1994 / Trinity Study 1998) suggests $50,000/year expenses requires $1.25M portfolio (50,000 ÷ 0.04).
Variants: Lean FIRE ~$1M (minimal expenses), Regular FIRE ~$1.25-2M, Fat FIRE ~$3M+ ($100k+/yr spend). Pre-59½ withdrawal from 401(k)/Traditional IRA triggers 10% penalty; Roth contributions can be withdrawn anytime tax-free; SEPP/72(t) allows penalty-free 401(k) withdrawals before 59½ via Substantially Equal Periodic Payments.
Social Security retirement range: 62 (early, ~30% benefit reduction) to 70 (delayed, 24% increase over Full Retirement Age 67).

With $50,000 in annual expenses and a 4% withdrawal rate, you need $1,250,000 to be financially independent. Starting from $200,000 and saving $30,000 per year at 8% returns, you will reach FIRE in 14 years. Your savings rate is 38%. Remember that Social Security benefits starting at age 62-70 can supplement your withdrawals and effectively reduce the portfolio you need. Consider maximizing your 401(k) employer match and Roth IRA contributions first.
Which FIRE path fits you?

This FIRE calculator determines how much you need to achieve financial independence in the US using the safe withdrawal rate method. Your FIRE number equals your annual expenses divided by your chosen withdrawal rate. At the standard 4% rate, you need 25 times your annual expenses. Each year, your existing portfolio grows by the expected return rate, and your annual savings are added on top.
For example, with $50,000 in annual expenses and a 4% SWR, your FIRE number is $1,250,000. Starting with $200,000 in net worth and saving $30,000 per year at an 8% return, you would reach FIRE in approximately 16 years. Your savings rate of 38% is a key driver: higher savings rates dramatically reduce the time to financial independence because they simultaneously increase contributions and prove you can live on less.
401(k), IRA, and Roth: Your FIRE Toolkit
American FIRE seekers have several powerful tax-advantaged accounts. The 401(k) allows up to $24,500 in pre-tax contributions in 2026 ($32,500 if 50 or over), plus any employer match. The Roth IRA allows $7,500 per year ($8,600 if 50 or over) in after-tax contributions with tax-free growth and withdrawals. A common FIRE strategy is to max the 401(k) match first, then max the Roth IRA, then go back and max the 401(k), and finally invest in taxable brokerage accounts.
Social Security as a FIRE Supplement
Social Security provides income starting at age 62 (reduced) through 70 (maximum benefit). The average retired-worker benefit was $2,071 a month in January 2026 ($24,852 a year, SSA). Delaying past full retirement age adds 8% a year up to 70. A couple both receiving the average would collect about $49,704 a year, which sharply reduces the portfolio needed once benefits start. Many early retirees plan a bridge strategy from their portfolio to Social Security.
Accessing Retirement Funds Early
A common concern for early retirees is accessing 401(k) and IRA funds before age 59.5. The Roth conversion ladder is the most popular solution: convert Traditional IRA funds to Roth IRA each year, wait 5 years, then withdraw the converted amount penalty-free. Meanwhile, Roth IRA contributions can be withdrawn anytime. The Rule of 55 allows 401(k) withdrawals if you leave your employer at 55+. SEPP (72t) payments allow penalty-free withdrawals at any age based on life expectancy calculations.
The Impact of Savings Rate
Your savings rate is the single most important variable in your FIRE journey. Starting from zero, spending everything you do not save and retiring at a 4% withdrawal rate, a 10% savings rate takes about 42 years at a 7% return. At 25%, that drops to about 28 years. At 50%, it is about 15 years. At 75%, about 7 years. (At a more cautious 5% inflation-adjusted return: about 52, 32, 17 and 8 years.) This calculator shows how increasing your savings rate, whether by earning more or spending less, can shave years or even decades off your working career. The key insight is that saving more simultaneously increases your investments and decreases the amount you need.
How to calculate your FIRE number
Your FIRE number is your annual spending divided by your safe withdrawal rate. At the standard 4% rule that is 25 times what you spend in a year: spending $50,000 a year needs $1,250,000. A cautious 3.5% rate, often used for retirements expected to last 40 to 50 years, raises the multiple to about 28.6×, and 3.25% to about 30.8×.
| Annual spending | FIRE number (4%) | At 3.5% |
|---|---|---|
| $30,000 | $750,000 | $857,143 |
| $40,000 | $1,000,000 | $1,142,857 |
| $50,000 | $1,250,000 | $1,428,571 |
| $60,000 | $1,500,000 | $1,714,286 |
| $75,000 | $1,875,000 | $2,142,857 |
| $100,000 | $2,500,000 | $2,857,143 |
| $150,000 | $3,750,000 | $4,285,714 |
Spending, not income, sets the target. Count what you will still pay after you stop working, including health insurance before Medicare at 65, which the FIRE healthcare bridge calculator prices separately.
How much income does the 4% rule give? $1 million, $2.5 million and more
Multiply the portfolio by 0.04 for the first year's withdrawal, then raise that dollar amount with inflation each year. On $1,000,000 that is $40,000 a year, or $3,333 a month, before tax.
| Portfolio | Per year (4%) | Per month |
|---|---|---|
| $500,000 | $20,000 | $1,667 |
| $750,000 | $30,000 | $2,500 |
| $1,000,000 | $40,000 | $3,333 |
| $1,250,000 | $50,000 | $4,167 |
| $1,500,000 | $60,000 | $5,000 |
| $2,000,000 | $80,000 | $6,667 |
| $2,500,000 | $100,000 | $8,333 |
| $3,000,000 | $120,000 | $10,000 |
| $5,000,000 | $200,000 | $16,667 |
Withdrawals from a 401(k) or traditional IRA are taxed as income; qualified Roth withdrawals are not. Before 59½, pre-tax money usually comes out penalty-free through a route such as a Roth conversion ladder or 72(t) SEPP payments. To test how long a different withdrawal lasts at your own return and age, use the retirement withdrawal calculator.
How many years until I can retire early? Years to FIRE by savings rate
Starting from zero and living on whatever you do not save, the years to financial independence depend almost entirely on your savings rate. At a 7% real return, saving 25% of take-home pay takes about 28 years; saving 50% takes about 15.
| Savings rate | Years at 5% real | Years at 7% real |
|---|---|---|
| 10% | 52 | 42 |
| 15% | 43 | 36 |
| 20% | 37 | 31 |

Does Social Security lower your FIRE number?
Yes, from the age you claim it. At a 4% withdrawal rate every $1,000 a month of benefit does the work of $300,000 of portfolio. The average retired-worker benefit, $2,071 a month in January 2026, is worth about $621,300. Before you claim, your portfolio has to cover everything, so early retirees usually plan two phases: the full FIRE number until they claim (62 at the earliest, 70 at the latest), and a smaller one after. The Social Security calculator shows your check at each claiming age.
Sources: SSA 2026 COLA fact sheet (average retired-worker benefit, 2.8% COLA); SSA delayed retirement credits; IRS Notice 2025-67 (2026 401(k) and IRA limits); IRS Rev. Proc. 2025-19 and 2026-24 (HSA limits); Bengen (1994) and the Trinity Study (1998) for the 4% rule.
How to use this calculator
- Enter your annual expenses. This is how much you spend per year on all living costs including housing, food, transport, healthcare, and discretionary spending. Your last 12 months of bank and card statements are the most reliable starting point.
- Set your current net worth (savings plus investments minus debts) and annual savings amount. Your annual savings includes 401(k), IRA, Roth IRA, HSA contributions, and any additional taxable account investments.
- Adjust the expected annual return rate. A diversified portfolio of US and global index funds has historically returned 7% to 10% annually. A conservative estimate of 7% to 8% accounts for fees and potentially lower future returns.
- Set your safe withdrawal rate (SWR). The standard 4% rule means withdrawing 4% of your portfolio in the first year, then adjusting for inflation. Consider 3.5% for added safety if you plan to retire very early (before 40).
- Review your FIRE number, years to FIRE, and the Lean/Regular/Fat FIRE thresholds. Expand the year-by-year projection to see how your net worth grows over time toward your FIRE target.
❓ Frequently Asked Questions
What is FIRE and how does it work in the US?
FIRE (Financial Independence, Retire Early) means building enough investments to cover your living expenses indefinitely through passive income and withdrawals. In the US, FIRE planning involves leveraging tax-advantaged accounts like 401(k), IRA, Roth IRA, and HSA, while factoring in Social Security benefits at age 62-70.
The standard approach uses the 4% safe withdrawal rate, meaning you need 25 times your annual expenses saved to reach financial independence.
How much do I need to FIRE in the US?
Using the 4% rule, you need 25 times your annual expenses. If you spend $50,000 per year, your FIRE number is $1,250,000.
Social Security reduces the portfolio you need once it starts: at a 4% withdrawal rate, every $1,000 a month of benefit replaces $300,000 of portfolio. The average retired-worker benefit was $2,071 a month in January 2026 (SSA), the income of a $621,300 portfolio — but only from the age you claim, so an early retiree still needs the full amount to bridge the years before it.
How do 401(k) and IRA accounts help with FIRE?
The 401(k) allows pre-tax contributions up to $24,500 in 2026 ($32,500 if 50 or over; $35,750 at ages 60 to 63), reducing your current tax bill and growing tax-deferred. The Roth IRA allows tax-free growth and withdrawals with contributions accessible penalty-free anytime.
Traditional IRA contributions may be tax-deductible. A common FIRE strategy is to maximize 401(k) employer match first, then max Roth IRA, then go back to max 401(k).
Can I access retirement accounts before 59.5 without penalty?
Yes, there are several strategies. Roth IRA contributions (not gains) can be withdrawn anytime tax and penalty-free.
The Rule of 55 allows penalty-free 401(k) withdrawals if you leave your job at 55 or later. Substantially Equal Periodic Payments (SEPP/72t) allow penalty-free withdrawals at any age.
The Roth conversion ladder lets you access converted funds after a 5-year waiting period.
What is the 4% safe withdrawal rate?
The 4% rule, based on the Trinity Study, states that withdrawing 4% of your portfolio in the first year of retirement, then adjusting annually for inflation, has a high probability of lasting 30+ years. On a $1,000,000 portfolio, you would withdraw $40,000 in year one.
Some modern research suggests 3.5% may be more appropriate given current market valuations and longer retirement horizons for early retirees.
How does Social Security affect my FIRE plan?
Social Security provides income starting as early as 62 (a 30% reduction if your full retirement age is 67) or as late as 70 (a 24% increase over full retirement age). The average retired-worker benefit was $2,071 a month in January 2026, after the 2.8% COLA (SSA).
Social Security effectively reduces your FIRE number because it replaces a portion of your expenses. Many early retirees plan to bridge from their portfolio to Social Security.
What is Lean FIRE vs Fat FIRE in America?
Lean FIRE means living on $25,000 to $40,000 per year, requiring $625,000 to $1,000,000. This works best in low-cost areas of the Midwest or South.
Fat FIRE means $100,000+ per year, requiring $2,500,000+, allowing for a comfortable lifestyle in any city. Most American FIRE aspirants target Regular FIRE at $40,000 to $60,000 per year.
How does the HSA help with FIRE?
The HSA (Health Savings Account) is the only triple-tax-advantaged account: tax-deductible contributions ($4,400 self-only / $8,750 family in 2026, rising to $4,500 / $9,000 in 2027 per IRS Rev. Proc. 2026-24), tax-free growth, and tax-free withdrawals for medical expenses.
After 65, HSA funds can be withdrawn for any purpose (taxed as income, like a Traditional IRA). Many FIRE planners maximize HSA contributions, invest the funds, and pay medical expenses out of pocket to let the HSA grow.
What is the impact of savings rate on FIRE?
Your savings rate is the single most important variable. Starting from zero, spending everything you do not save, and retiring at a 4% withdrawal rate, a 10% savings rate takes about 42 years to reach financial independence at a 7% return.
At 25%, about 28 years. At 50%, about 15 years.
At 75%, about 7 years. At a more cautious 5% inflation-adjusted return the same rates take about 52, 32, 17 and 8 years.
This is because a higher savings rate simultaneously increases contributions and proves you can live on less. Going from 15% to 25% cuts about 8 years off the timeline at a 7% return.
Should I pay off my mortgage before pursuing FIRE?
Compare your mortgage rate with the return you expect from investing. Paying off a mortgage guarantees a risk-free return equal to your interest rate and lowers your annual expenses, reducing your FIRE number.
However, mortgage interest is deductible if you itemize, and investing the money may build wealth faster. Many FIRE planners keep the mortgage if the rate is below 4% and pay it off if above 5%.
