Can I retire at 55 with $500,000 as a single person?

At 55, a single person with $500,000 has 12 years before a full Social Security check at 67, and that bridge is why the classic 4% rule overstates the safe budget here, as the comparison below shows. The useful question is which lever (spending, claim age or stock mix) you'd most want to flex if your number doesn't fit.

What 10,000 simulated retirements say

Your 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 $2,071 monthly Social Security we assume for you and the budget comes to $3,740. But benefits don't start until 67, so for the first 12 years the portfolio pays the whole $3,740 on its own. Simulated, that budget lasts to 95 in 25% 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 $2,550.

How the money holds up over time

Spending $2,550 a month, the median simulated household still holds $645K at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $70K, and in a lucky one (90th percentile) it's $2.24M. Among the futures where the money lasts, the typical balance left at 95 is $1.05M — the cushion that a 90% target buys, more than the $500,000 you started with.

Push spending to $2,850 a month and about 24% of simulated futures run dry before 95. When that happens, the median age the money runs out is 78, and the earliest tenth of those failures arrive by 66. 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 $2,550 a month and changing one thing at a time, the biggest improvement comes from delaying Social Security to 70, which moves the odds from 92% to 94%. 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 79%.

Our read

Waiting to 70 helps the single retiree

Unlike the couple version, a single 55-year-old with $500,000 gains from waiting: claiming at 70 moves the odds at $2,550 a month from 92% to 94%. The portfolio can carry 15 years of full withdrawals, and the larger check guards against the big single-retiree risk, outliving the money.

Health coverage is the other decade-long cost, with 10 years until Medicare. A single person funding $2,550 a month partly from Roth contributions or a taxable account can keep MAGI low enough for meaningful marketplace subsidies; pulling the same amount from a traditional IRA counts in full.

Of everything tested, the 2032 cut does the most damage here (79%), because from 67 your benefit would cover most of this budget. Two ways to build margin: leave work at 60, which supports $2,950, or reach 55 with $750,000, which supports $3,200.

One benefit, one plan

No spousal or survivor benefit backs this plan up: your $2,071 check is the only income that can't run out. From 67 it covers 81% of $2,550; savings carry the rest for life. There's no partner to share two other costs with, either: the Administration for Community Living estimates almost 70% of people turning 65 will need some long-term care, which this simulation doesn't model, and the single-filer IRMAA surcharge applies above $109,000 of MAGI, half the joint level.

   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 $138K.

How we ran these numbers

• You, 55, retiring in 2026 with $500,000 invested (home equity not counted) and no further contributions. Social Security of $2,071 a month at full retirement age, SSA's January 2026 average retired-worker benefit, 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.
