Can I retire at 55 with $1.5 million as a couple?

At 55, a couple with $1.5 million has 12 years before full Social Security at 67 and two claiming decisions to make: whether one of you claims early to shorten the bridge, whether both of you wait, and how much stock risk to carry through the first decade. The lever table below shows which of those matters most for this household.

What 10,000 simulated retirements say

Your household's odds of lasting to 95 at each all-in monthly budget, in today's dollars. See how we ran these numbers.

The 4% rule versus the simulation

The 4% rule says $1.5 million supports $5,000 a month from the portfolio. Add the $3,208 monthly Social Security we assume for the two of you and the budget comes to $8,210. But benefits don't start until 67, so for the first 12 years the portfolio pays the whole $8,210 on its own. Simulated, that budget lasts to 95 in 51% of futures. The rule badly overstates what's safe here: a 12-year bridge to Social Security drains the portfolio before benefits arrive. The 90%-odds budget is $5,900.

How the money holds up over time

Spending $5,900 a month, the median simulated household still holds $2.24M at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $291K, and in a lucky one (90th percentile) it's $7.65M. Among the futures where the money lasts, the typical balance left at 95 is $3.57M — the cushion that a 90% target buys, more than the $1.5 million you started with.

Push spending to $6,900 a month and about 24% of simulated futures run dry before 95. When that happens, the median age the money runs out is 81, and the earliest tenth of those failures arrive by 72. By then Social Security is paying, so running short means living on benefits alone for what could be a decade or more.

What moves the odds

Holding spending at $5,900 a month and changing one thing at a time, the biggest improvement comes from both of you delaying to 70, which moves the odds from 91% to 92%. Delay pays because savings can carry three more years, and the 24% larger check then covers more of the budget for life, which matters most in the long-lived futures. The biggest downside is a more conservative 30%-stock mix, which takes the odds to 81%.

Our read

Big medians, late failures

The median couple spending $5,900 a month still has $2.24M at 85 and leaves $3.57M at 95, in today's dollars. In the futures that fail at $6,900, the money runs out late, around 81, often after decades that looked fine.

That combination is the profile where spending more early is most defensible, as long as there's an agreed plan to adjust after bad years. It is also where deciding whose benefit to maximize matters, since the survivor's late-life income will rest on it; both delaying to 70 lifts the odds to 92%.

Another five years of work, to 60, lifts the safe budget to $6,700, though at this level it mostly enlarges the estate, since the median household already holds $2.24M at 85. The weightier choice is the mix: a 30%-stock portfolio drops the odds to 81%.

If one of you is left

We assume both of you reach 95. At the first death, the survivor keeps the larger check and the $1,137 one stops, a 35% cut to household benefits. At $5,900 a month, the $2,071 left covers 35% of spending instead of 54%; savings fill the gap. From the year after, a widow or widower without a dependent child files as single: narrower brackets, and the Medicare surcharge (IRMAA) above $109,000 of MAGI rather than $218,000.

   Rule of 55

   Leave your employer in or after the year you turn 55 and that 401(k) is penalty-free now. IRAs wait until 59½, by which point this budget will have drawn about $319K.

How we ran these numbers

• Both spouses, 55, retiring in 2026 with $1.5 million invested (home equity not counted) and no further contributions. Social Security of $2,071 + $1,137 a month at full retirement age, SSA's January 2026 average for an aged couple, claimed at 67 and indexed to inflation.
• 60/35/5 stocks, bonds and cash; spending flat in today's dollars, taxes and health insurance included; success means lasting to 95 with both alive.
