To retire at 55, you need enough invested to cover all your spending until Social Security starts, and the shortfall after that, for 40 or more years. You also need a way to reach retirement accounts before 59½ without the 10% early-withdrawal tax, and health insurance until Medicare at 65. This guide walks through each step with numbers.
How much do you need to retire at 55?
Size the portfolio year by year. Until Social Security starts, it pays your whole budget; from then on, only spending minus benefits. Every year is valued at the same rate, set by your withdrawal rate and how long retirement lasts. We use 3.5% because a retirement starting at 55 should last to 95: in our backtest of 1928-2025 data [18], 3.5% with a 60/40 portfolio lasted 40 years in 98% of start years, and research on even longer, 50-60 year retirements found that 3.25%-3.5% survived the worst historical conditions[17].
| Yearly spending | No Social Security | With Social Security at 67 |
|---|---|---|
| $40,000 | $1,142,857 | $647,119 |
| $60,000 | $1,714,286 | $1,218,547 |
| $80,000 | $2,285,714 | $1,789,976 |
| $100,000 | $2,857,143 | $2,361,405 |
Our calculation: 3.5% withdrawal rate, money lasts to 95, today's dollars. Social Security of $28,000 a year from 67.
For $60,000 a year, the 12 years from 55 to 67, when the portfolio pays the whole budget, account for $651,989 of the $1,218,547 target. The other $566,558 covers the $32,000 gap from 67 to 95. Both parts are valued at 1.86%, the real rate at which a 3.5% withdrawal lasts exactly 40 years, so the early years get the same safety margin as the rest. The expected market return does not change the target. That is why retiring at 55 costs $304,262 more than the simple multiple of the gap ($914,286) suggests. Our FIRE number calculator and early retirement calculator run this math with your own ages and benefits.
Can you retire at 55 with $500,000, $1 million or $2 million?
$1,000,000 at 55 supports about $52,351 a year of total spending, Social Security included, and $500,000 about $34,851. The same assumptions as above: $28,000 of Social Security from 67, a 3.5% withdrawal rate and money that lasts to 95 (our calculation).
| Invested at 55 | Yearly spending it supports | Monthly |
|---|---|---|
| $500,000 | $34,851 | $2,904 |
| $750,000 | $43,601 | $3,633 |
| $1,000,000 | $52,351 | $4,363 |
| $1,500,000 | $69,851 | $5,821 |
| $2,000,000 | $87,351 | $7,279 |
Spending here is your whole budget, including taxes, health insurance and travel. Each extra $250,000 adds about $8,750 a year. If the number that matches your budget is out of reach, the sections below on working a few more years and part-time income show the cheapest ways to close the gap.
What is the step-by-step plan to retire at 55?
- Write your retirement budget, including taxes and health insurance before 65.
- Get your Social Security estimate from the SSA[8] and pick a claiming age.
- Calculate your number at 55 with the bridge years included, as in the table above.
- Close the gap with catch-up contributions from age 50.
- Plan how you will reach each account before 59½: taxable money first, then the Rule of 55, 72(t) or a Roth ladder.
- Arrange health coverage for the 10 years before Medicare.
- Stress-test the plan against bad markets and keep a cash buffer for the first years.

How much can you save after 50?
Catch-up contributions let you save more in the last stretch. For 2026, the 401(k) limit is $24,500, plus an $8,000 catch-up from age 50, and a larger $11,250 catch-up at ages 60-63[4]. IRAs allow $7,500 plus a $1,100 catch-up.
Maxing a 401(k) with catch-ups from 50 to 55 ($32,500 a year) builds about $175,281 in today's dollars by 55, at a 3.79% real return. A couple who both do it doubles that.
How much you need to invest each year to reach the $1,218,547 target by 55 depends on where you start (our calculation, today's dollars):
| Age now | Invested now | Needed each year |
|---|---|---|
| 45 | $200,000 | $78,107 |
| 45 | $400,000 | $53,710 |
| 50 | $500,000 | $114,299 |
| 50 | $800,000 | $47,315 |
Amounts above the 401(k) and IRA limits go into a taxable account, which is also the easiest money to spend before 59½. If the figure for your row is out of reach, the comparison of retirement ages below shows how much a later date saves.
How do you get your money before 59½?
Withdrawals from 401(k)s and IRAs before 59½ normally carry a 10% additional tax, but several IRS exceptions apply[1]. The three most useful for a 55-year-old retiree:
| Method | Works with | How it works | Catch |
|---|---|---|---|
| Rule of 55 | The 401(k) or 403(b) of the job you leave | Leave that employer in or after the year you turn 55, and withdrawals from its plan are penalty-free | Not IRAs or old employers' plans; roll old 401(k)s in before you leave |
| 72(t) payments | IRAs and workplace plans | Substantially equal periodic payments based on life expectancy | Changing the payments before the later of 5 years or age 59½ brings back the 10% tax on every earlier payment, plus interest[2] |
| Roth conversion ladder | Traditional IRA converted to Roth | Convert a slice each year; converted amounts can come out later | Each conversion has its own 5-year period[3] |
A taxable brokerage account needs no exception at all, which is why many early retirees spend it first. The Rule of 55 is the simplest of the three if most of your money is in your current employer's plan.
How the Rule of 55 works in practice
The rule applies when you separate from service during or after the calendar year you turn 55, or 50 for public safety employees[1]. So someone who turns 55 in November can leave in March of that year and still qualify, but leaving in the year before you turn 55 does not. It covers qualified plans such as 401(k)s, not IRAs, so rolling the 401(k) into an IRA after you leave gives up the exception for that money. Ask your plan how it pays out before you leave.
A 72(t) example at 55
If most of your money is in an IRA, 72(t) payments are the main route. At 55, the IRS single life expectancy is 31.6 years[3]. For a $400,000 IRA, the fixed amortization method at 5% (the rate can be up to the greater of 5% or 120% of the federal mid-term rate) pays about $25,445 a year, and the RMD method about $12,658 in the first year (our calculation). Payments must run until the later of five years or 59½[2], which means until 60 if you start at 55.
Roth money and taxable accounts
Regular Roth IRA contributions come out first and are not income[3], so they can be spent at any age. In a taxable account only the gain is taxed: in 2026 a married couple with no other income can realize about $131,100 of long-term gains with no federal income tax, thanks to the standard deduction and the 0% capital gains band[5] (our calculation).
How will you pay for health insurance until Medicare?
Medicare starts at 65[9], so retiring at 55 means 10 years of private coverage. Leaving a job with health coverage qualifies you for a Special Enrollment Period in the ACA Marketplace[10]. COBRA keeps your employer plan for up to 18 months[11], which covers only the start of the gap, and a working spouse's plan is the other common option.
Plan around the subsidy cliff. With the enhanced premium tax credits gone, income above 400% of the poverty level gets no subsidy, and that is still true for 2027 coverage[15]. Marketplace savings use the previous year's poverty guidelines[12], so for 2027 the line is about $63,840 for one person and $86,560 for a couple (our calculation). Above it the full premium is yours: KFF put the national average benchmark silver premium for a 60-year-old at $15,914 a year in 2026[14]. Paying that from 60 to 65 alone adds $69,974 to the $1,218,547 target at 55 (our calculation).
Early retirees control their income more than most people. Traditional IRA and 401(k) withdrawals and capital gains count toward Marketplace income, while qualified Roth distributions do not[13]. Spending from cash, Roth contributions and taxable sales with a high cost basis can keep income under the line, while large IRA withdrawals or Roth conversions can push it over.
How much tax will you pay if you retire at 55?
Often very little federal tax, because you choose which accounts to draw from. If all $60,000 came from a traditional 401(k), a married couple would withdraw about $63,227 and owe $3,227 of federal income tax; a single person would withdraw $65,705 and owe $5,705 (our calculation from 2026 brackets and the standard deduction[5]; state tax not included).
The bigger risk is health insurance, not tax. Those withdrawals count as Marketplace income[13]: the couple's $63,227 sits under their $86,560 subsidy line, but the single person's $65,705 is above the $63,840 line and loses the subsidy entirely. Mixing in Roth contributions or taxable sales with little gain fixes that.
What happens at each age after you retire at 55?
- 55: Rule of 55 withdrawals from your last employer's 401(k); COBRA or a Marketplace plan for health cover.
- 59½: the 10% additional tax no longer applies to any 401(k) or IRA[1].
- 60: 72(t) payments started at 55 can stop[2].
- 62: the earliest Social Security claim, 30% smaller than at full retirement age[6].
- 65: Medicare[9], which ends the need for private health cover.
- 67: full retirement age for anyone born in 1960 or later. In our example, portfolio withdrawals drop from $60,000 to $32,000 a year.
- 73: required minimum distributions generally start from traditional accounts[16].
When should you claim Social Security?
Later claiming lowers the portfolio you need, but only if you can afford the longer bridge. Full retirement age is 67 for anyone born in 1960 or later; claiming at 62 cuts the benefit by 30%, and waiting to 70 adds 24%[6]. Here is what that does to the target for $60,000 of spending:
| Claim at | Yearly benefit | Needed at 55 |
|---|---|---|
| 62 | $19,600 | $1,284,203 |
| 67 | $28,000 | $1,218,547 |
| 70 | $34,720 | $1,181,572 |
Our calculation, same assumptions as above. The differences are smaller than the benefit changes suggest, because a later claim means more bridge years. Claiming later also protects you if you live a long time, since benefits are paid for life and adjusted for inflation.
Counting benefits in today's dollars, a claim at 67 overtakes a claim at 62 at about age 79, and a claim at 70 overtakes 67 at about 82.5 (our calculation). One more thing changes when you stop at 55: your benefit is based on your highest 35 years of indexed earnings, and missing years count as zero[7]. If you started work at 22, retiring at 55 leaves you with 33 years, so ask the SSA for an estimate that assumes no further earnings, not the default one that assumes you keep working.
Should you retire at 55, 57, 60 or 62?
Fifty-five is a natural line because the Rule of 55 starts to apply, but each extra year of work helps twice: you save more, and the target itself shrinks because the bridge to Social Security is shorter. With the same $60,000 budget and Social Security at 67, retiring at 60 instead of 55 needs about $1,103,188, versus $1,218,547 at 55, before counting five more years of contributions.
| Retire at | Needed | Years before Social Security | Cost of years before 59½ | Years before Medicare |
|---|---|---|---|---|
| 55 | $1,218,547 | 12 | $261,384 | 10 |
| 57 | $1,174,799 | 10 | $148,071 | 8 |
| 60 | $1,103,188 | 7 | none | 5 |
| 62 | $1,051,732 | 5 | none | 3 |
Our calculation: $60,000 a year, $28,000 of Social Security from 67, 3.5% withdrawal rate, money lasting to 95. Retiring at 60 removes the early-access problem entirely and halves the years of private health insurance. If you are close but not there, a target of 57 or 58 can be a better plan than stretching the withdrawal rate. The trade-off is the healthy years you give up, which no spreadsheet can price for you.
What mistakes do people make when retiring at 55?
- Rolling the 401(k) into an IRA at the wrong time. It gives up the Rule of 55 for that money.
- Using a 30-year withdrawal rate for a 40-year retirement. At 55, plan to 95 and use a lower rate than 4%.
- Budgeting COBRA as the whole health plan. It lasts 18 months; the gap to Medicare is ten years.
- Taking one big IRA withdrawal that lifts income over the subsidy line for the year.
- Using the default Social Security estimate, which assumes you keep earning until you claim.
- Ignoring sequence risk. A bad market in the first few years does the most damage; keep a cash buffer or flexible spending.
What if you are not on track?
You have four levers: save more now, spend less later, work a little longer, or work part-time for a few years after 55. Part-time income is powerful because it shortens the bridge; our Barista FIRE guide shows how much it can cut the target.
