How much do you need to retire at 55?

Target = Annual Spending ÷ 0.035   (≈ 28.6×)
Target = Annual Spending ÷ 0.0325  (≈ 30.8×)

Fifty-five sits in an awkward spot: too early for Medicare, too early for unrestricted IRA withdrawals, but late enough that one specific 401(k) rule starts working in your favor. The headline number is the easy part — divide annual spending by a withdrawal rate suited to a 40-year horizon. The harder part is the three age-specific rules that decide whether that number actually works. This page covers both.

Why 55 changes the math

The 4% rule — and the 25× multiplier that follows from it — comes from research on 30-year retirements. Retire at 55 with a reasonable chance of living into your mid-90s and you are planning for closer to 40 years. In the historical US data, stretching a 4% initial withdrawal over 40 years fails meaningfully more often than over 30, so the standard adjustment is to lower the starting rate.

There is no single agreed figure, but 3.25–3.5% is the range most long-horizon analyses point to. The arithmetic consequence:

1 ÷ 0.035  = 28.57…  → about 28.6× annual spending
1 ÷ 0.0325 = 30.77…  → about 30.8× annual spending

For a household spending $60,000 a year:

$60,000 ÷ 0.035  = $1,714,286
$60,000 ÷ 0.0325 = $1,846,154

Call it $1.71M–$1.85M, versus $1.5M under the plain 4% rule. The gap — a couple hundred thousand dollars — is the price of the extra decade.

Targets by annual spending

Every figure below is annual spending divided by the withdrawal rate, rounded to the nearest dollar.

Read the 3.25% and 3.5% columns as the planning range and the 4% column as the optimistic floor. If your target lands near $2 million, is $2 million enough to retire? works the same question at ages 50 and 60 — at 3.25–3.5%, $2M supports $65,000–$70,000 a year.

The three factors specific to age 55

Healthcare before Medicare

Medicare eligibility starts at 65, so retiring at 55 means buying your own coverage for ten years. Under ACA marketplace rules (as of 2026), insurers can charge older enrollees up to three times what a 21-year-old pays, which puts your late 50s and early 60s at the expensive end of the curve. Rather than guess at premiums, give healthcare its own line in the spending figure you capitalize. If you budget an extra $12,000 a year for premiums and out-of-pocket costs, that single line adds $12,000 ÷ 0.035 ≈ $343,000 to $12,000 ÷ 0.0325 ≈ $369,000 to the target. Underestimating this line is the most common error in retire-at-55 plans.

The rule of 55 for your 401(k)

As of 2026, if you leave your job — quit, laid off, or fired — 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. Ordinary income tax still applies. The rule covers only the plan at the employer you just left: IRAs and 401(k)s still sitting with previous employers don’t qualify, which is one reason people planning a 55 exit sometimes roll old plans into their current 401(k) rather than out of it. Check your plan document, too — some plans only permit a full lump-sum distribution, which blunts the rule’s usefulness.

IRAs wait until 59½

Traditional IRA withdrawals before age 59½ generally incur a 10% additional tax on top of ordinary income tax (as of 2026). The main exceptions: substantially equal periodic payments under section 72(t), which lock you into a rigid withdrawal schedule for at least five years or until 59½, whichever is longer; and Roth IRA contributions (not earnings), which you can withdraw at any age without tax or penalty. Practically, retiring at 55 means treating IRA balances as money that comes online four and a half years into retirement, not on day one.

The bridge: funding 55 to 59½

Put those rules together and the plan becomes a sequencing exercise. Years one through four and a half are funded from the penalty-free pool: a taxable brokerage account, cash savings, Roth IRA contribution basis, and a rule-of-55 401(k). At 59½, every retirement account opens up. At 65, Medicare arrives and the healthcare line drops. The total portfolio decides whether you can retire at 55; the location of the money decides whether the first five years are smooth or expensive. If the penalty-free pool can’t cover roughly 4.5 years of spending on its own, the fix is usually redirecting contributions toward taxable accounts in the final working years — not saving a larger total.

If you’re not at the target yet, two related checkpoints help: Coast FIRE tells you whether your current balance would compound to the goal by 55 without further contributions, and the calculator below projects the year you reach the full number.
