A US-specific calculator that respects the rules that actually matter at 55: the Rule of 55 for 401(k) access, the 59½ penalty cliff for IRAs, Medicare eligibility at 65, and your Social Security claim age.
Your projected savings cover spending and pre-Medicare healthcare through age 90 with current inputs.
Retiring at 55 in the US means bridging two gaps: 55 → 59½ (when most retirement accounts are penalty-free), and 55 → 65 (when Medicare kicks in and health premiums drop sharply).
The calculator uses your taxable brokerage and Rule-of-55 401(k) balance as your bridge, and adds an ACA-style health premium until age 65. See our 401(k) vs IRA guide for how to build that bridge, and 401(k) match strategies to maximise it before you leave work.
You can claim as early as 62 (~30% reduced), at your Full Retirement Age of 67 (born 1960+), or wait to 70 for delayed retirement credits (~+24% vs FRA). Claiming later usually wins if you have the bridge funds to wait — read our full Social Security claiming guide.

Four common savings targets, using a 3.3%–4% safe withdrawal rate across a 40-year retirement. Add Social Security (typically $1,600–$3,800/mo depending on earnings history and claim age) on top from age 62–70.
A $500k portfolio supports roughly $1,400–$1,670/month before tax (3.3%–4% withdrawal). Realistic only if your home is paid off, you'll take Social Security at 62–67, and you can keep annual spending under $35,000 — or you plan on part-time income during the pre-Medicare years. States with no income tax and lower housing costs (Tennessee, Texas, Florida panhandle) make this much more workable than California or New York.
$1M supports roughly $2,750–$3,300/month from the portfolio. With Social Security starting at 62–67 (~$1,800–$2,800/mo for an average earner), total retirement income lands around $54,000–$73,000/yr — a comfortable retirement in most low- and mid-cost states.
$2M supports roughly $5,500–$6,600/month from the portfolio, indefinitely. Layered with Social Security you'll be at $90,000–$120,000/yr — generous in most of the US and comfortable in HCOL states as long as housing is controlled. Plan Roth conversions in the 55–70 window to reduce future RMDs.
$4M supports $11,000–$13,300/month pre-tax — high-income retirement anywhere in the US. At this level the questions become tax efficiency, estate planning, and whether to concentrate Roth conversions in the low-income gap years between retirement and Social Security.
A part-time bridge income of even $15,000–$25,000/yr can cut portfolio withdrawals nearly in half during the 55–62 pre-Social-Security window, dramatically reducing sequence-of-returns risk in the most fragile years of an early retirement. Common shapes: consulting in your former field, seasonal work, teaching, or a small business. Keep an eye on the Social Security earnings test if you've already claimed — before Full Retirement Age (67), earnings above $23,400 (2025) reduce benefits by $1 for every $2 over the limit. See our Social Security claiming guide for the full math on why most early retirees delay claiming until 67 or 70.
It's tight but possible. Using the 4% rule, $500k supports roughly $20,000/yr — about $1,670/month before tax. That works if your housing is paid off, you'll receive Social Security at 62–67, and you keep spending under $35k with a part-time income bridge. Most planners suggest closer to $750k–$1M for a comfortable 40-year retirement at 55.
For an average US household, $1 million at 55 supports about $33,000–$40,000/yr in pre-tax income (using a 3.3%–4% withdrawal rate over 40 years) — enough for a modest retirement in low-cost states, especially once Social Security starts. Add a paid-off home and it becomes comfortable in states like Florida, Tennessee, or Texas.
Yes — $2M supports roughly $66,000–$80,000/yr pre-tax indefinitely. Combined with Social Security starting at 62–70, that's a $90k–$120k gross retirement income. Comfortable in most US states and generous in the Sun Belt.
$4M at 55 supports roughly $130,000–$160,000/yr pre-tax using a safe withdrawal rate. That's high-income retirement anywhere in the US, including HCOL states like California or New York. Focus shifts to tax efficiency (Roth conversions before RMDs) and estate planning.
If you leave your employer in or after the calendar year you turn 55, you can withdraw from that employer's 401(k) or 403(b) without the 10% early withdrawal penalty. Income tax still applies, and it doesn't cover IRAs or old 401(k)s from prior jobs.
Yes, but normally with a 10% penalty plus tax. The main exception is a 72(t) SEPP — Substantially Equal Periodic Payments — which locks you into a strict schedule for at least 5 years or until 59½, whichever is longer.
Most early retirees use the ACA marketplace, COBRA for up to 18 months, or a spouse's plan. Premiums vary widely — $800–$1,500/month is a reasonable planning number; ACA subsidies can lower this significantly if your taxable income is modest.
No — the earliest you can claim Social Security is age 62, and doing so permanently reduces your benefit by about 30% compared to Full Retirement Age (67 for anyone born 1960 or later). Retiring at 55 means bridging 7+ years to your first Social Security check using portfolio withdrawals or part-time income.
Yes. Many early retirees take on consulting, contract, or seasonal work — sometimes called 'Barista FIRE' or 'Coast FIRE'. Even $15,000–$25,000/yr of part-time income can cut portfolio withdrawals in half during the pre-Medicare years, protecting against sequence-of-returns risk. Before FRA (67), earnings above $23,400 (2025) reduce Social Security if you've already claimed — a reason to delay claiming.
If you have enough bridge savings and average life expectancy, waiting until 67 or 70 produces a much larger inflation-adjusted check and acts as longevity insurance. Claiming at 62 makes sense if you need the income or have a shorter expected lifespan.
