Retire at 45 Calculator

A $1 million portfolio lets you retire at 45 on about $35,000 a year, using the 3.5% withdrawal rate I’d plan on for a retirement that could run 50 years. If you spend $50,000, the number is about $1,428,571, and at $60,000 it’s $1,714,286.

How much do you need to retire at 45?

Your spending divided by your withdrawal rate gives the target. In today’s dollars:

The 3.5% has a specific source. In the 1994 paper that gave us the 4% rule, William Bengen found that 4% never emptied a half-stock, half-bond portfolio in under 33 years, and that rates up to about 3.5% lasted at least 50 years in every period he tested. For someone who stops at 45, 50 years runs to 95, so his longest test lines up with the retirement you’re planning. The better-known Trinity Study stopped at 30-year periods and can’t say much about yours.

Longer tests point the same way. Karsten Jeske’s safe withdrawal rate series, which uses U.S. data back to 1871, found a 4% rate with a 50/50 portfolio worked about 95% of the time over 30 years and about 65% over 60. I’d drop to 3.25% only if you have no Social Security coming and no willingness to earn anything again.

Is $1 million enough to retire at 45?

It pays about $35,000 a year at 3.5%, and that $35,000 has to cover health insurance and income tax as well as rent and groceries. For a single person with a paid-off home or a cheap one, that can work. For a family renting in a large city, it won’t.

A million also goes further if you’d earn something in your late 40s. Part-time income lowers what you take out, and it means selling fewer shares in the early years, when a bad market does the most damage. The Barista FIRE calculator shows how much smaller the number gets.

Can you coast to 45 instead of saving to the end?

Only if you started early. This is what you’d need invested now, at 7% returns and 3% inflation, to stop contributing and still reach the full number at 45:

Even the smallest budget here asks a 30-year-old for $645,348, which few people have at that age. By 35 the coast number is 68% of the full target, and by 40 it’s 83%, so from the mid-30s on you’re really just saving for FIRE. For most readers, 45 is a full FIRE goal with coasting as the backup plan, which works best aimed at 50.

Theo: close to $1 million at 45, and still short

Theo is 38 and single. He has $520,000 invested, adds $4,000 a month and spends $45,000 a year. If he keeps that up, he’ll have about $1,063,000 at 45, the million he’s been aiming at. At 3.5% his target is $1,285,714, so his million pays about $37,000 a year, $8,000 less than he spends.

He never crosses his Coast FIRE line for 45, which is normal with seven years to go. Move the finish line to 50, though, and he reaches Coast FIRE at 45. He could leave his career then, take any job that covers his $45,000 and let the balance grow to about $1,287,000 by 50 without adding to it. If I were Theo, that’s the plan I’d write down, and I’d treat an earlier finish as a bonus.

Fourteen and a half years before 59½

Most early withdrawals from a 401(k) or IRA before 59½ carry a 10% additional tax. At $45,000 a year, 45 to 59½ is $652,500 of spending, about half of Theo’s target. The rule of 55 won’t help, because it only applies if you leave your job in or after the year you turn 55.

A taxable brokerage account can be spent at any age, and Roth IRA contributions come out before earnings, free of tax and the 10%. A Roth conversion ladder opens pre-tax money one year at a time. Each conversion waits five years, counted from January 1 of the year you convert, so converting at 45 unlocks that money at 50. Until then, the brokerage account and Roth contributions carry you. 72(t) payments also avoid the 10%, but start them at 45 and you’re tied to the schedule for 14½ years. The retire at 50 page explains each option in more detail.

For Theo, that means the next seven years of saving matter as much for where they go as for how much. He needs about $225,000 he can reach before 50. I’d keep taking his full employer match and send a good share of the rest to a brokerage account, and to a Roth IRA if his income allows, even though it costs some tax now. Getting stuck at 47 with all his money in a 401(k) would cost him more.

Twenty years before Medicare

Medicare starts at 65. COBRA can extend your job’s plan for up to 18 months, at the full premium plus 2%, which gets you to about 46½. The next 18½ years are usually a Marketplace plan.

What catches people is the age curve. Insurers can charge older enrollees up to three times what they charge younger ones, so the premium Theo pays at 46 is far below what the same plan will cost him at 60. I’d budget the health line for the late-50s price from the start and let the early years run under budget.

Subsidies depend on income, not savings. HealthCare.gov counts most IRA and 401(k) withdrawals as income but not qualified Roth distributions, so the mix you draw from each year changes what you pay. Our guide to health insurance before 65 goes through the subsidy math.

What 23 years of work means for Social Security

Your benefit comes from your highest 35 years of indexed earnings, and missing years count as zeros. Work from 22 to 45 and you have 23 years, so 12 zeros go into your average. Your statement assumes you keep earning your current pay until you claim, so it will overstate what you’ll get.

Even a realistic figure doesn’t lower a 45-year-old’s target much. Say Theo expects $20,000 a year from 67. If his portfolio covers the full $20,000 for each of the 22 years before then, his target drops only from $1,285,714 to $1,154,286, still above the $1,063,000 he’d have at 45. The Social Security version of the calculator runs that for your own benefit.

There’s also the program’s funding. The 2026 Trustees Report projects the retirement trust fund runs out of reserves in late 2032, after which incoming taxes would cover about 78% of scheduled benefits unless Congress acts. With 22 years to wait, I’d count on part of the benefit and treat the rest as a cushion.

What a crash in year one would do

Suppose Theo reaches exactly $1,285,714, takes out $45,000 for his first year, and the market then falls 30%. He’s left with $868,500, and next year’s $45,000 is 5.2% of it, with almost 50 years still to fund. A drop like that at 75 matters much less, because there are far fewer years left to pay for.

The fix is flexibility rather than a perfect rate. Spending a little less for a couple of years after a bad market, or picking up some work, keeps a crash from becoming permanent. Before you commit, the 4% rule calculator shows how often a rate survives 50 years of random markets, and the Monte Carlo calculator shows how often you’d hit the number by 45 in the first place. If your plan only works when the first five years go well, it isn’t ready.
