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

Retiring as a single person at 45 with $750,000 is a 50-year planning problem, one of the longest financial commitments you can make. The first years of withdrawals decide most of it: a 2008-style drawdown early on leaves a very different path than retiring into a calm decade, which is why this page reports odds rather than a single projection.

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 $750,000 supports $2,500 a month from the portfolio. Add the $2,071 monthly Social Security we assume for you and the budget comes to $4,570. But benefits don't start until 67, so for the first 22 years the portfolio pays the whole $4,570 on its own. Simulated, that budget lasts to 95 in 23% 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 $2,600.

How the money holds up over time

Spending $2,600 a month, the median simulated household still holds $1.61M at 85 (in today's dollars). In an unlucky future — the 10th percentile — it's down to $78K, and in a lucky one (90th percentile) it's $6.54M. Among the futures where the money lasts, the typical balance left at 95 is $2.82M — the cushion that a 90% target buys, more than the $750,000 you started with.

Push spending to $3,050 a month and about 23% of simulated futures run dry before 95. When that happens, the median age the money runs out is 67, and the earliest tenth of those failures arrive by 61. 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 $2,600 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 82%.

Our read

Where waiting for 70 starts to pay

This is the first age-45 scenario where delaying Social Security helps: at $2,600 a month, claiming at 70 moves the odds from 91% to 92%. With $750,000 the portfolio can carry three extra years of withdrawals, and the check that follows is 24% larger than at 67, for life.

The trade-off is that more of the risk lands in your 50s and 60s. The first decade of returns matters far more than the long-run average, because withdrawals during a downturn lock in losses. In the futures that fail at $3,050 a month, the money most often runs out around 67. Keeping the next few years of spending in bonds or cash means a bad market at 50 doesn't force you to sell stocks at the bottom.

The two cleanest upgrades are more time and more money. Five more years on the payroll, to 50, lifts the safe budget to $2,900; reaching 45 with $1 million instead of $750,000 gets you $3,200. Most people land between the two, with a few years of part-time earnings that shorten the bridge without a second full career.

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 80% of $2,600; 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.

How we ran these numbers

• You, 45, retiring in 2026 with $750,000 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. 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.
