Can I retire at 45 with $1.5 million as a couple?

Retiring as a couple at 45 with $1.5 million between you means planning for two life expectancies. The odds that at least one of you reaches your 90s are much higher than for either of you alone, so you're funding 50 years of household spending, 22 of them before either Social Security check arrives.

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 22 years the portfolio pays the whole $8,210 on its own. Simulated, that budget lasts to 95 in 32% of futures. The rule badly overstates what's safe here: a 22-year bridge to Social Security drains the portfolio before benefits arrive. The 90%-odds budget is $4,850.

How the money holds up over time

Spending $4,850 a month, the median simulated household still holds $3.37M at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $184K, and in a lucky one (90th percentile) it's $13.5M. Among the futures where the money lasts, the typical balance left at 95 is $5.85M — the cushion that a 90% target buys, more than the $1.5 million you started with.

Push spending to $5,850 a month and about 25% of simulated futures run dry before 95. When that happens, the median age the money runs out is 70, and the earliest tenth of those failures arrive by 62. 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 $4,850 a month and changing one thing at a time, nothing tested improves the odds by more than a point, so this budget is already close to its best setup. The biggest downside is a more conservative 30%-stock mix, which takes the odds to 79%.

Our read

Taxes become the main lever

At this level the question shifts from whether the money lasts to how much of it goes to taxes. If most of the $1.5 million sits in traditional accounts, required distributions from 75 can push a couple into higher brackets and Medicare surcharges, which start at $218,000 of joint MAGI in 2026. Thirty years between retiring and 75 is an unusually long window to convert to Roth in low brackets.

That window has a cost in your 40s and 50s: conversions raise MAGI, which shrinks marketplace subsidies before Medicare. Most couples split the difference by converting up to the top of a chosen bracket each year. The simulation's $4,850 budget is conservative, too: the median household still holds $3.37M at 85.

Put a number on that RMD pressure. If the whole median balance at 75, $2.37M, were still in traditional accounts, the first required distribution would be roughly $96K, taxable whether or not you spend it. Stopping at 50 instead would raise the 90%-odds budget to $5,350, but for this couple five more paychecks matter less than how much of the pile is converted before then.

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 $4,850 a month, the $2,071 left covers 43% of spending instead of 66%; 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.

How we ran these numbers

• Both spouses, 45, 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. Leaving work this early often lowers the real figure; check yours at ssa.gov/myaccount.
• 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.
