On $60,000 a year in spending, your FIRE number is $1,500,000. On $80,000, it’s $2,000,000. The math is simple — but most people get the inputs wrong, which means the target is wrong too. For more on this topic, see our guide: What Is the FIRE Movement? A Realistic Guide for Normal People in 2026 — With Real Numbers.
The Formula Behind the Number
Your FIRE number = annual expenses × 25.
That multiplier comes from the 4% rule. A portfolio withdrawn at 4% per year has historically survived 30-year retirements across nearly every market condition since 1926. Multiply your spend by 25 and you have the portfolio size that makes 4% cover your bills.
The variable that matters most isn’t your income. It’s your spending.
Most people earning $150,000 a year never ask that question seriously. They estimate. Estimates are almost always low.

What $1M, $2M, and $3M Actually Support
A $1,000,000 portfolio supports roughly $40,000 a year in spending. In most of the US, that’s lean. No slack. Say you’re a software engineer in Austin who retires at 45 with exactly $1M. At $40K/year, you’re living on $3,333/month. That covers a modest apartment, a paid-off car, groceries at H-E-B, and not much else.
$2,000,000 changes the math. $80,000/year — $6,667/month — covers most people’s actual lifestyle, including travel and healthcare. Most dual-income households are targeting this range, whether they’ve named it or not.
$3,000,000 at 4% gives you $120,000 a year. $10,000/month. Comfortable for most of the country, even accounting for healthcare inflation.
What most FIRE spreadsheets miss: pre-Medicare healthcare costs. A couple retiring in their early 50s can pay $1,500–$2,000/month for ACA marketplace coverage. That’s $18,000–$24,000/year. Budget it in before you quit.
The Inputs That Break the Calculation
Annual expenses. This is your spending number, not your income. Most people undercount by 15–20%. Go through 12 months of actual bank and credit card statements. Include irregular expenses: car insurance paid annually, dental work, vacations. If you track $5,000/month but actually spent $67,000 last year, your FIRE number just moved from $1.5M to $1.675M.
Withdrawal rate. 4% is the standard. But retiring at 40 means a 50-year horizon, not 30. Some planners use 3.5% for early retirees — a multiplier of ~28.5×. On $60,000/year spending, that’s $1.71M instead of $1.5M. A $210,000 difference.
Taxes on withdrawals. Every dollar from a traditional 401(k) or IRA is ordinary income. A single person withdrawing $80,000/year in 2026 has a taxable income of $65,000 after the $15,000 standard deduction. Federal tax on that: roughly $9,300. Your gross FIRE number needs to be higher than your net spending target.
Roth accounts fix this. Roth IRA withdrawals in retirement are tax-free. Most people building toward FIRE underweight Roth conversion in their early accumulation years. That’s a real cost.
Social Security. Most people who retire at 40 or 45 will still collect eventually — just less of it. The SSA calculates your benefit on your top 35 earning years. Retire at 43 with 20 years of work history and the remaining 15 years default to $0. Reduced benefit, not zero. Factor a reduced amount in at 62 or 67 when building your model.
Real Scenarios: $1M to $3M
Scenario 1: Single, $1.2M, retiring at 48 in Denver
$1.2M at 4% = $48,000/year — $4,000/month. Rent in Denver’s Capitol Hill neighborhood runs about $1,600/month for a 1BR per Zillow (May 2026). That’s $19,200/year, leaving roughly $28,800 for everything else. It works, but there’s no cushion. A bad first decade in markets could force a spending cut.
That rent is 40% of monthly take-home. Above the 30% threshold financial planners use as the affordability cut-off. At that ratio, building savings takes serious discipline.

Rent burden: 40.0% of take-home.
Scenario 2: Couple, $2.5M, retiring at 52 in Raleigh
$2.5M at 4% = $100,000/year. A 2BR in North Hills, Raleigh runs around $1,900/month per Zillow (May 2026). After taxes on a mix of Roth and traditional withdrawals, this couple nets roughly $88,000–$92,000/year — about $7,500/month. That’s $23% of monthly take-home going to rent. Below the 30% threshold. Solid.
Scenario 3: Single, $3M, retiring at 55 in Chicago
$3M at 4% = $120,000/year. Chicago’s Lincoln Park neighborhood averages around $2,200/month for a 1BR per Zillow (May 2026). Illinois taxes income at a flat 4.95%. A single filer withdrawing $120,000/year owes roughly $5,940 in state tax plus ~$16,000 federal — netting about $98,000. $8,166/month. That rent is 26.9% of monthly take-home — just under the 30% threshold. Workable.

Denver at $1.2M scores a 4.4. Difficult. One bad market sequence in the first five years could force cuts or part-time work. Most FIRE planners recommend at least one additional year of savings before pulling the trigger at that portfolio size.
How the Same Portfolio Plays Out Across States
Most people building a FIRE plan focus on the portfolio number. They don’t think hard enough about where they’ll withdraw it. State income tax on retirement withdrawals is a real variable — and it doesn’t show up in most FIRE calculators.
Estimated annual tax on $80,000 traditional IRA withdrawal — 6 states (2026):
- 🟢 Texas — ~$6,800 (federal only, no state income tax)
- 🟢 Nevada — ~$6,800 (federal only, no state income tax)
- 🟡 Colorado — ~$9,800 combined (4.4% flat state rate)
- 🟡 Illinois — ~$10,600 combined (4.95% flat state rate)
- 🔴 New York — ~$12,400 combined (up to 6.85% marginal)
- 🔴 California — ~$14,200 combined (up to 9.3% marginal)
Source: IRS Publication 15-T + state revenue departments.
Texas vs. California on $80,000/year in traditional account withdrawals: a $7,400/year gap. Over 30 years, that’s $222,000 in extra take-home. No investment strategy produces that kind of gain from zero risk. Retiring to a no-tax state is one of the few moves that materially changes your required portfolio size.
Most FIRE planners in California don’t realize the state taxes traditional IRA withdrawals at the same rate as wages. Zero special treatment. That’s real money over a 30-year retirement.
Quick Answers About Your FIRE Number
What is the FIRE number formula? Annual expenses × 25. That gives you the portfolio size needed to withdraw 4% per year, based on historical market returns going back to 1926.
Is $1 million enough to retire early? At 4%, $1M supports $40,000/year. In a low-cost city with no mortgage, that’s livable. In a high-cost city or with significant healthcare costs, it’s tight. Most single people targeting early retirement aim for $1.5M–$2M minimum.
Does the 4% rule still hold in 2026? It’s debated. Some researchers now recommend 3.3%–3.5% given current valuations and lower expected bond returns. Using 3.5% pushes your multiplier to ~28.5× — about 14% more portfolio than the classic formula.
What if I have a pension or Social Security? Reduce your required portfolio by the annual income × 25. If you’ll collect $15,000/year from Social Security at 67, that’s equivalent to $375,000 in your FIRE portfolio. Subtract that from your target.
How do I account for taxes in my FIRE number? If your money is in traditional pre-tax accounts, gross up your spending target before applying 25×. On $60,000 net spending with a 10% effective tax rate, your gross target is $66,667 — and your FIRE number is $1,666,667, not $1,500,000. Roth accounts eliminate this adjustment entirely.
Three Moves That Add Real Money to Your FIRE Timeline
Max your 401(k). The 2026 limit is $23,500 ($31,000 if 50+) per IRS Notice 2024-80. At a 22% marginal rate, maxing your 401(k) saves roughly $5,170 in federal tax annually. Net cost to you: about $18,330 out-of-pocket for $23,500 in retirement savings.
Add the HSA. The 2026 individual limit is $4,300 per IRS Rev. Proc. 2025-19. Triple tax advantage: deductible going in, grows tax-free, withdraws tax-free for medical expenses. After 65, you can withdraw for anything and pay ordinary income tax — it becomes a second IRA.
Fix your W-4. If you get a large refund each April, you’re giving the IRS an interest-free loan. Adjust your withholding and redirect that money into your brokerage monthly instead. For someone overwithholding by $3,000/year, that’s $250/month that could be working in a market account.
High-yield savings for your cash buffer. Ally and Marcus were at 4.5%–5.0% APY as of early 2025 — rates change, check current rates before moving cash. Keep 1–2 years of living expenses in a HYSA as a buffer against sequence-of-returns risk in the early years of retirement. That buffer lets you avoid selling equities in a down market.

FAQ
What bi-weekly amount does a $2M portfolio produce?
At 4%, $2M yields $80,000/year — $3,077 bi-weekly or $6,667/month. After federal taxes on $80K from a traditional IRA (single filer, $15,000 standard deduction, taxable income $65,000), you owe roughly $9,300 in federal tax — netting about $70,700/year or $5,892/month. Roth withdrawals skip that tax entirely.
Can I retire early on $1M if I also work part-time?
Yes — and it’s common. Many early retirees work 10–20 hours a week for the first few years. If part-time work covers $20,000/year, your portfolio only needs to produce $40,000/year. On $60,000 total spending, that’s $1M at 4%. This is sometimes called “barista FIRE” or “semi-FIRE.” It significantly reduces sequence-of-returns risk in the vulnerable early years.
What if I’m self-employed and building toward FIRE?
Self-employed people can contribute to a Solo 401(k) up to $70,000 total (employee + employer contributions) in 2026 — far more than a standard 401(k). SE tax runs 15.3% on the first $176,100 of net earnings per the SSA wage base. That’s the biggest drag on accumulation for freelancers and business owners. Use our self-employment tax calculator — SE tax adds 14.13% on net earnings, which catches a lot of people off guard.
How does inflation affect my FIRE number?
The 4% rule assumes inflation-adjusted withdrawals — you increase your annual draw by inflation each year to maintain purchasing power. At 3% inflation, a $60,000/year withdrawal becomes $80,635 in 10 years. Your portfolio needs to grow faster than your withdrawals increase. Historically, a 60/40 stock-bond portfolio has cleared that bar, but past performance doesn’t guarantee future results.
Is a FIRE number different from a standard retirement number?
Only in timeline. A traditional retirement at 65 means a 25–30 year horizon. A FIRE retirement at 45 means 45–50 years. Longer timelines need either a lower withdrawal rate (3.5% instead of 4%) or a larger portfolio. The formula is identical — the inputs are more conservative for early retirees.
