Can I retire at 55 with $1,000,000 as a couple?
In our 10,000-path simulation, a couple retiring at 55 with $1,000,000 can spend about $4,600 a month in today's dollars — Social Security included once it starts at 67 — with a 90% chance the money lasts to age 95. Accept 75% odds and the number rises to $5,200 a month.

At 55, a couple with $1,000,000 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.
| Monthly spending | Chance money lasts to 95 |
|---|---|
| $3,700 | 100% |
| $4,600 | 90% |
| $5,200 | 76% |
| $6,000 | 51% |
| $6,800 | 31% |
The 4% rule versus the simulation
The 4% rule says $1,000,000 supports $3,330 a month from the portfolio. Add the $3,208 monthly Social Security we assume for the two of you and the budget comes to $6,540. But benefits don't start until 67, so for the first 12 years the portfolio pays the whole $6,540 on its own. Simulated, that budget lasts to 95 in 37% 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 $4,600.
How the money holds up over time
Spending $4,600 a month, the median simulated household still holds $1.35M at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $142K, and in a lucky one (90th percentile) it's $4.73M. Among the futures where the money lasts, the typical balance left at 95 is $2.21M — the cushion that a 90% target buys, more than the $1,000,000 you started with.
| Age | Unlucky (10th pct.) | Typical (median) | Lucky (90th pct.) |
|---|---|---|---|
| 75 | $242K | $1.02M | $2.77M |
| 85 | $142K | $1.35M | $4.73M |
| 95 | $3K | $1.88M | $7.71M |
Push spending to $5,200 a month and about 24% of simulated futures run dry before 95. When that happens, the median age the money runs out is 80, and the earliest tenth of those failures arrive by 69. 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 $4,600 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 90% 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 22% benefit cut from 2032, which takes the odds to 81%.
| At $4,600/month, if you… | Chance money lasts | vs. baseline |
|---|---|---|
| Baseline: balanced mix, Social Security at 67 | 90% | — |
| More conservative mix (30% stocks) | 82% | −8 pts |
| Growth mix (85% stocks) | 90% | no change |
| Claim Social Security at 62 (both) | 86% | −4 pts |
| Delay Social Security to 70 (both) | 92% | +2 pts |
| 22% benefit cut from 2032 (trust-fund shortfall) | 81% | −9 pts |
Our read
Most of the plan runs through the tax code
A couple at 55 with $1 million has 20 years before RMDs begin at 75, and spending of $4,600 a month will likely come partly from pre-tax accounts. That makes this one of the scenarios where tax planning moves the outcome most.
Filling low brackets with Roth conversions each year can shrink later RMDs and soften the widow's tax penalty, when the survivor files single on nearly the same income. The limits are the subsidy cliff before 65 and IRMAA after it ($218,000 joint MAGI in 2026). The 2032 cut is this page's largest single risk, at 81%.
On claiming, the data is unambiguous for this couple: both waiting to 70 lifts the odds to 92%, a bigger gain than any other change tested, and $1 million can fund the extra years. Retiring at 60 rather than now would add a different kind of margin, raising the safe budget to $5,250.

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 $4,600 a month, the $2,071 left covers 45% of spending instead of 70%; 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.

Born 1971, so RMDs start at 75 under SECURE 2.0, on a median $1.02M. From 63 on, conversion income counts toward Medicare's IRMAA surcharge, which applies above $218,000 of joint MAGI.

How we ran these numbers
- Both spouses, 55, retiring in 2026 with $1,000,000 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.
- 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.
