Retiring at 55: how much you need, and how to bridge the years

Yes, many people can retire at 55. It comes down to two things: having enough saved to cover your spending for 30 years or more, and a plan for the years before Medicare (65) and Social Security (62 to 70) start helping.

There's no single magic number. Someone who spends $40,000 a year needs a very different nest egg from someone who spends $100,000. This guide walks through a simple way to size your own, and the rules and gaps that matter most when you stop at 55.

This is general education, not advice. Your situation, your plan's rules and tax law all matter. Check the details with your plan administrator, SSA and a licensed professional before you decide.

Rules checked against IRS.gov, SSA.gov, Medicare.gov and HealthCare.gov on October 16, 2026.

How much do you need to retire at 55?

The honest answer is "it depends on what you spend." A rough way to work it out, in three steps:

1. Your yearly spending in retirement. Start from what you spend today. Take out costs that will end (commuting, retirement saving itself, maybe a mortgage) and add ones that will start, especially health insurance.
2. Subtract income you can count on. A pension, rental income, part-time work. Social Security too, but only from the age you plan to claim it.
3. Turn the gap into a nest egg. A common rule of thumb is 25 times the yearly gap, which is the 4% rule turned around. That rule was built on 30-year retirements. Retiring at 55 may mean 35 or 40 years, so some people plan on a lower rate, such as 3.5% (about 29 times the gap).

A made-up example

Say someone plans to spend $60,000 a year, plus $12,000 a year for health insurance until Medicare. They expect about $25,000 a year from Social Security if they claim at 67. All numbers are made up and round, and the sketch ignores inflation and investment growth.

• The long run (67 on): $60,000 − $25,000 = $35,000 a year from savings. At 25 times, that's $875,000.
• The bridge (55 to 67): until Social Security starts, savings also cover the $25,000 it will later pay. Twelve years × $25,000 = $300,000.
• Health cover (55 to 65): ten years × $12,000 = $120,000.

That's about $1.3 million in this sketch. The point isn't the total. It's that the bridge years can add a lot, and that each piece is something you can change: spend a little less, earn a little in the early years, or claim Social Security at a different age.

The FIRE number calculator works this out with your own spending, and the withdrawal rate explorer shows how long a given balance might last.

Reaching your money before 59½

Most retirement accounts charge a 10% additional tax on withdrawals before 59½, unless an exception applies (IRS). At 55 that's four and a half years to plan around.

The rule of 55. If you leave your employer during or after the calendar year you turn 55, withdrawals from that employer's plan generally skip the 10% additional tax. Regular income tax still applies. Old 401(k)s from earlier jobs and IRAs don't qualify, and rolling the plan into an IRA after you leave gives up the exception. Your plan must also allow partial withdrawals. The rule of 55 covers the details and the questions to ask your plan.

Other ways in. Savings in a regular taxable account, a governmental 457(b), Roth IRA contributions, a Roth conversion ladder and 72(t) payments are all options. Getting to your money before 59½ compares them side by side.

Many people who stop at 55 mix two or three of these, then decide which account to spend first to keep taxes low.

Health cover until Medicare at 65

For many people, this is the hardest part of retiring at 55. Medicare generally starts at 65, with a seven-month Initial Enrollment Period around your 65th birthday (Medicare.gov). Until then, the main options are:

• COBRA: keep your employer's plan, usually for up to 18 months, but you typically pay the full premium plus up to 2% (DOL).
• An ACA marketplace plan: losing job-based coverage opens a Special Enrollment Period from 60 days before to 60 days after you lose it (HealthCare.gov). Premium tax credits depend on your income, and for 2026 they're generally limited to households at or under 400% of the federal poverty level. How you draw on your accounts changes the income the marketplace sees.
• A spouse's or partner's plan, retiree coverage from your employer, or a part-time job with benefits.

Price this before you pick a leaving date. Health insurance before Medicare walks through each option, and Medicare in plain English covers signing up on time at 65.

Social Security: when, not just how much

You can start Social Security any month from 62 to 70. For anyone born in 1960 or later, full retirement age is 67. Starting at 62 pays about 30% less for life, and each year you wait past 67 adds 8%, up to 70 (SSA, SSA).

Two things are worth knowing if you stop at 55:

• Your benefit is based on your highest 35 years of earnings (SSA). Stopping early can mean more zero years, so your estimate may come in lower than you'd guess. A free my Social Security account shows yours.
• Waiting is often paid for by savings. The later you claim, the bigger the bridge your savings have to cover, and the bigger the lifetime check. It's a trade, and couples have more to weigh.

When to claim Social Security and Social Security at 62, 67 or 70 go deeper, and the Social Security timing calculator runs the numbers.

If you're still working: catch-up contributions

Starting later isn't starting too late. From the year you turn 50, the IRS lets you save more. For 2026, that's an extra $8,000 in a 401(k), 403(b), governmental 457(b) or TSP (or $11,250 at ages 60 to 63), and an extra $1,100 in an IRA (IRS).

A few years of catch-ups before 55 can make a real dent in the bridge. Catch-up contributions after 50 has the full limits, the new Roth rule for higher earners, and how to turn the limit into a payroll percentage.

The risks to plan around

The first years carry the most weight. A bad market in the first five to ten years after you stop can hurt more than the same market later, because you're selling while prices are down. This is called sequence of returns risk. Common ways people soften it: a cash cushion for a year or two of spending, a little part-time income in the early years (earning a little in early retirement), and spending that can flex in a bad year. The Retirement Timing Meter shows the market backdrop you'd be stepping into, as context rather than a forecast.

A long horizon. Money may need to last 35 to 40 years. Inflation matters more over that long, and so does keeping some growth in the mix.

Taxes. Pre-tax withdrawals are taxed as income, and that income can change your health subsidies. The order you draw from accounts matters.

Not being sure you have enough. That's normal. One more year is about knowing when enough is enough, and uFIRE Seasons is for people who'd rather take a break now and retire for good later.

A simple plan for retiring at 55

1. Write down your spending, including health insurance before 65.
2. List your income by age: pension, part-time work, Social Security at the age you'd claim.
3. Size the two stretches: the bridge years and the long run.
4. Match accounts to years: which money pays for 55 to 59½, and which after.
5. Price health cover for your state and household.
6. Check your Social Security estimate and earnings record.
7. Ask your plan whether it allows partial withdrawals after you leave.
8. Keep saving while you can, including catch-ups.
