Can I retire at 45 with $750,000 as a couple?

Retiring as a couple at 45 with $750,000 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 $750,000 supports $2,500 a month from the portfolio. Add the $3,208 monthly Social Security we assume for the two of you and the budget comes to $5,710. But benefits don't start until 67, so for the first 22 years the portfolio pays the whole $5,710 on its own. Simulated, that budget lasts to 95 in 9% 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 $2,950.

Notice that $2,950 is less than the $3,208 a month Social Security pays from 67. The limit here is the 22-year bridge, not the decades after it: these numbers hold spending flat for life, so a plan that spends less before 67 and more once benefits start can support a higher lifetime budget than this table shows.

How the money holds up over time

Spending $2,950 a month, the median simulated household still holds $1.44M at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $11K, and in a lucky one (90th percentile) it's $6.03M. Among the futures where the money lasts, the typical balance left at 95 is $2.61M — the cushion that a 90% target buys, more than the $750,000 you started with.

Push spending to $3,450 a month and about 23% of simulated futures run dry before 95. When that happens, the median age the money runs out is 63, and the earliest tenth of those failures arrive by 59. That falls inside the wait for benefits at 67; the emergency valve would be claiming early, at a permanently reduced check.

What moves the odds

Holding spending at $2,950 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 both of you delaying to 70, which takes the odds to 85%.

Our read

Health insurance is the hidden line item

Twenty years separate this couple from Medicare. At $2,950 a month for everything, two marketplace premiums are a large share of the budget. Subsidies are set by modified adjusted gross income, not by what you spend, so how you fund spending matters: taking back Roth contributions or spending cash basis from a brokerage account adds little to MAGI, while traditional IRA withdrawals count in full.

That puts health costs in tension with the other big early-retirement move, Roth conversions, which raise MAGI in the same years. Model both before choosing. The simulation's $2,950 budget leaves a median of $2.61M at 95 in the futures where the money lasts, so there is room to trade some of that cushion for lower lifetime taxes.

Claiming advice needs adjusting, too. Both of you holding out to 70 drops the odds to 85%, because a 22-year bridge on $750,000 can't absorb three more years of full withdrawals; claiming both at 62 lands at 90%, roughly where the 67 baseline sits. For this couple, full retirement age is close to the best simple choice.

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 $2,950 a month, the $2,071 left covers 70% of spending instead of all of it; 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 $750,000 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.
