Can I retire at 45 with $500,000 as a couple?

Retiring as a couple at 45 with $500,000 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 $500,000 supports $1,670 a month from the portfolio. Add the $3,208 monthly Social Security we assume for the two of you and the budget comes to $4,880. But benefits don't start until 67, so for the first 22 years the portfolio pays the whole $4,880 on its own. Simulated, that budget lasts to 95 in 2% 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 $1,950.

Notice that $1,950 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 $1,950 a month, the median simulated household still holds $980K at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $19K, and in a lucky one (90th percentile) it's $4.06M. Among the futures where the money lasts, the typical balance left at 95 is $1.76M — the cushion that a 90% target buys, more than the $500,000 you started with.

Push spending to $2,400 a month and about 24% 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 58. 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 $1,950 a month and changing one thing at a time, the biggest improvement comes from both of you claiming at 62, which moves the odds from 91% to 98%. Claiming early wins here because the gap before benefits is the binding problem: five fewer years of full withdrawals outweigh a permanently smaller check. The biggest downside is both of you delaying to 70, which takes the odds to 86%.

Our read

Claiming early shortens a very long bridge

For this couple, claiming Social Security at 62 instead of 67 lifts the odds at $1,950 a month from 91% to 98%, and waiting until 70 drops them to 86%. That runs against the usual advice to delay if you can. The reason is the bridge: every year of waiting is another year the portfolio pays the full budget alone.

Couples have a middle path the simulation doesn't model directly, which is to split the decision. The lower earner can claim early to shorten the drawdown while the higher earner waits, because the larger benefit becomes the survivor's benefit after the first death. That protects whichever of you lives longer without asking the portfolio to carry a 25-year bridge.

Health coverage for two is the other long bill, twenty years of it before Medicare. Marketplace premium tax credits are set by your household income, not by the $500,000 you hold, and a $1,950 budget drawn first from cash, taxable savings or Roth contributions keeps that income modest. Postponing your exit to 50 would lift the safe budget to $2,450.

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. The $2,071 left still exceeds this $1,950 budget, so the survivor's exposure is the years before 67. 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 $500,000 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.
