It’s safe to say that nearly everyone hopes to have a solid savings and retirement account by the time they turn 45. The dream is to retire early enough to truly enjoy the years ahead. If you can set aside $1 million by this age, the logical next question is whether you actually should and can step away from work for good.
For followers of the FIRE movement (financial independence, retire early), that question comes down to a few concrete factors: lifestyle expectations, cost of living, and how much you can realistically spend each year without depleting your nest egg too soon.
How Much Can You Spend?
Most people pursuing early retirement use the 4% safe withdrawal rule as their starting benchmark. Applied to a $1 million portfolio, that works out to $40,000 per year. The original research behind this rule, developed by financial planner Bill Bengen in 1994 and later validated by the Trinity Study, found that a 4% inflation-adjusted withdrawal survived every 30-year historical period. Bengen’s updated 2025 research actually suggests 4.7% may be supportable for 30-year retirements, but the tradeoff matters: for someone retiring at 45, the horizon could stretch 45 to 50 years, and many researchers now recommend a more conservative 3% to 3.5% to protect against that longer timeline.
The other lifeline to keep in mind is Social Security. You can begin claiming as early as age 62, though waiting until full retirement age (67 for those born in 1960 or later) maximizes your monthly check. The average monthly retirement benefit reached approximately $2,071 as of January 2026, according to the Social Security Administration. That supplement changes the math considerably once it kicks in, but it still leaves a multi-decade gap to bridge on savings alone.
Knowing that $40,000 is your annual ceiling ahead of Social Security will force some hard choices about where and how you live.
How It’s Possible To Retire
Retiring on $40,000 a year is achievable, but it requires choosing a low-cost state and a low-cost corner of that state. The Midwest and Southeast (South Florida excluded) have historically offered the most room on this budget. In rural or small-city parts of Kansas, Iowa, and Illinois, total annual expenses can fall comfortably below that $40,000 ceiling.
The brighter part of this picture is portfolio growth. If your $1 million stays invested, it should keep compounding even as you withdraw. At a 7% annualized return, $1 million grows to just under $4 million over 20 years. That means a larger principal base, more income-generating capacity, and a cushion against the unexpected. The key assumption is that your return exceeds 4% so the principal keeps growing rather than shrinking.
Getting there demands genuine lifestyle discipline. Regular restaurant dinners, multiple annual vacations, and frequent car upgrades are likely off the table. Carrying debt (credit card balances, car loans, a mortgage) makes this budget nearly impossible to sustain. Arriving at 45 with a paid-off home and a $1 million portfolio gives you the strongest possible foundation for making early retirement work.
When It’s Not Possible to Retire
The 4% rule’s $40,000 ceiling leaves almost no room to upgrade to a medium-cost location. Even the suburbs of mid-tier cities like Chicago, Kansas City, or Birmingham, Alabama, push comfortable annual expenses well above that threshold. A realistic budget for those areas is closer to $100,000 a year, which would exhaust a $1 million portfolio in 15 years or fewer, well before Social Security eligibility and long before Medicare begins at 65.
Healthcare is the stealth threat in any early retirement plan. For someone leaving the workforce at 45, there are 20 years of private insurance costs before Medicare coverage begins. Those premiums are significant and rising. According to data from the Urban Institute, average marketplace premiums for a 64-year-old already run roughly $1,100 per month, and rates increase with age. Starting from 45, you can easily accumulate hundreds of thousands of dollars in private insurance premiums before Medicare eligibility arrives. Making the picture harder, the enhanced premium tax credits that had suppressed ACA marketplace costs for the prior four years expired at the end of 2025 and were not renewed, meaning early retirees in 2026 face a steeper out-of-pocket burden than they would have anticipated even a year ago. Fidelity’s 2025 Retiree Health Care Cost Estimate found that a 65-year-old individual may need $172,500 in after-tax savings just to cover healthcare costs from that point forward, and an early retiree faces additional pre-Medicare costs on top of that figure.
Discretionary spending compounds the problem. Travel alone can run $10,000 or more per year, which equals 25% of the $40,000 safe withdrawal before a single housing or grocery bill is paid. Add in hobbies like golf, occasional larger purchases, or any lifestyle upgrades, and the math unravels quickly.
One practical middle ground is part-time work or a side business. Even modest earned income, say $15,000 to $20,000 a year, meaningfully reduces the pressure on the portfolio and, in many cases, can provide access to employer-sponsored health coverage, the single largest expense gap between age 45 and Medicare eligibility.
