FIRE in the United States: What to Know
The FIRE (Financial Independence, Retire Early) movement is particularly active in the US, where tax-advantaged accounts and relatively high salaries in certain industries create opportunities for aggressive saving.
Tax-advantaged accounts accelerate the path to FIRE
Maximizing 401(k), Roth IRA, and HSA contributions reduces current taxes and grows investments tax-efficiently. The "mega backdoor Roth" strategy, available through some 401(k) plans, can add an additional $46,000+ in annual Roth contributions. Understanding and using these accounts is central to most US FIRE strategies.
The 4% rule originated from US market data
The widely cited 4% safe withdrawal rate comes from the Trinity Study, based on US stock and bond market history. It suggests that withdrawing 4% of your portfolio in year one (adjusting for inflation thereafter) has historically sustained a 30-year retirement. Some people use 3.5% for longer retirements or 3% for added safety.
Accessing retirement funds before 59.5 requires planning
US early retirees need strategies to access funds before standard retirement age: Roth IRA contribution withdrawals (always penalty-free), Roth conversion ladders (5-year waiting period), SEPP/72(t) distributions, or relying on taxable brokerage accounts. Planning the bridge between early retirement and age 59.5 is a critical FIRE consideration.
Healthcare is the biggest pre-65 FIRE challenge
Without employer-sponsored insurance, ACA marketplace plans are the primary option. Premiums depend on income - FIRE practitioners often manage their taxable income carefully to qualify for subsidies. At very low declared incomes, premiums can be quite affordable. This interplay between withdrawals, taxes, and healthcare subsidies is a key FIRE planning element.

Getting Started
How to Use This FIRE Calculator for the United States
Enter your current financial position
Input your total invested assets across all accounts - 401(k), IRA, Roth, HSA, and taxable brokerage. Include current balances and annual contribution amounts.
Set your target annual spending
Enter your expected annual expenses in early retirement. Include healthcare costs, which will likely be higher without employer coverage. The calculator uses this to determine your FIRE number (typically 25x annual spending).
Adjust assumptions for your situation
Set expected investment returns, inflation rate, and withdrawal rate. Conservative assumptions (lower returns, higher inflation, lower withdrawal rate) give more confidence in the results.
Factor in Social Security as a future offset
Even FIRE retirees will likely receive Social Security eventually. Adding estimated benefits starting at your planned claiming age reduces the amount your portfolio needs to sustain long-term.
Review your FIRE date and savings rate
The calculator shows your projected FIRE date based on current inputs. Your savings rate (percentage of income invested) is the primary lever - even small increases can move the date significantly.

Common Questions
FIRE Calculator for United States - FAQ
Is this FIRE calculator really free?
Yes. The FIRE calculator is completely free - no payment, no email required. It runs in Google Sheets so you own and control your data.
What is a good FIRE number for the US?
It depends entirely on your annual spending. The standard formula is 25x annual expenses (based on a 4% withdrawal rate). If you spend $40,000/year, your FIRE number is $1,000,000. If you spend $80,000/year, it's $2,000,000. Location, healthcare costs, and lifestyle choices are the main variables.
How do I access 401(k) money before 59.5?
Common strategies include: Roth conversion ladder (convert Traditional to Roth, wait 5 years, withdraw penalty-free), Rule of 55 (if you leave your job at 55+), SEPP/72(t) distributions (equal periodic payments), or relying on taxable accounts to bridge the gap. Each has specific rules and tax implications.
Does this account for taxes on withdrawals?
The calculator provides a high-level projection. In practice, your tax situation in early retirement depends on which accounts you withdraw from and in what order. Pre-tax accounts are taxed as income, Roth withdrawals are tax-free, and taxable accounts have capital gains implications.
What savings rate do I need for FIRE?
The math is straightforward: at a 50% savings rate, you can reach FIRE in roughly 17 years; at 65%, roughly 10 years; at 75%, roughly 7 years. These assume starting from zero and reasonable investment returns. The FIRE calculator shows your specific timeline based on your actual numbers.
How do I handle healthcare costs in FIRE planning?
Budget for ACA marketplace premiums, which vary by state, age, and income. Many FIRE practitioners keep taxable income low to qualify for premium subsidies. A family plan might cost $500-1,500/month without subsidies. Once you reach 65, Medicare takes over, though it still has premiums and supplemental costs.
