Half a million dollars is a real accomplishment — and also the balance that makes a lot of people quietly anxious, because it sits right on the line between “enough” and “not sure.” The good news: $500,000 lasts longer than most headlines suggest once you account for Social Security and realistic spending. The honest news: how long it lasts swings widely based on choices you make. This guide gives you concrete scenarios, the factors that matter most, and a way to test your own plan rather than guess.
The short answer
At a 4% withdrawal — $20,000 a year, adjusted for inflation — $500,000 is designed to last about 30 years. Spend $30,000 a year from it and you’re closer to 20 years; spend $40,000 and it may run dry in around 13–15. Crucially, most retirees pair this with Social Security, which changes the math in your favor.
The reason $500,000 feels scarier than it needs to is that people imagine funding their entirelifestyle from it. In reality, it’s usually one piece of a bigger income picture.
Scenarios: how long $500,000 really lasts
Here’s roughly how $500,000 behaves at a 5% average annual return, before Social Security:
| Annual spending from the portfolio | Withdrawal rate | Roughly how long $500K lasts |
|---|---|---|
| $20,000 | 4% | 30+ years |
| $25,000 | 5% | ~25 years |
| $30,000 | 6% | ~20 years |
| $40,000 | 8% | ~13–15 years |
The shape is identical to a larger portfolio — your withdrawal rate drives the timeline more than the dollar amount. And as always, these assume steady average returns, which real markets don’t deliver.
Why Social Security is the game-changer at $500K
This is where $500,000 quietly outperforms its reputation. Say you need $45,000 a year to live, and Social Security provides $25,000 of it. Your portfolio only has to cover the remaining $20,000 — which is right at the 4% mark, meaning your $500,000 could comfortably last 30 years. Without that benefit, the same $45,000 lifestyle would drain it in about a decade.
The lesson: don’t judge $500,000 in isolation. Map your full income — Social Security, any pension, part-time work — then see what’s left for your savings to cover. The age you claim Social Security (62 to 70) swings this significantly, since waiting raises your monthly check.
The trap the scenario table hides
A clean table makes retirement look predictable. It isn’t. Two retirees with the same $500,000 and the same average return can end up worlds apart if one hits a bad market early while withdrawing. Selling shares into a downturn to fund spending locks in losses and accelerates depletion — a danger known as sequence of returns risk. It hits smaller portfolios especially hard, because there’s less cushion to absorb a rough start.
That’s why a single-number answer is risky. The realistic approach is to test your plan against many market paths and see the probability your money lasts. Stress-test your $500,000 free across 1,000 scenarios, including the unlucky early-crash cases.
The factors that actually matter
- Spending flexibility— the strongest protection against running out.
- Social Security timing— often the difference between “tight” and “fine.”
- Cost of living— $500,000 stretches far longer in a low-cost area.
- Investment mix— too safe loses to inflation; too aggressive risks early crashes.
- Inflation— at 3%, your costs roughly double over 30 years.
- Taxes— traditional-account withdrawals are taxable, lowering real income.
How to make $500,000 last longer
- Stay flexible with spending, especially in down markets.
- Delay Social Securityif you can — it’s guaranteed, inflation-adjusted income.
- Keep a cash buffer to avoid forced selling.
- Consider part-time income in the early years to ease withdrawals when sequence risk is highest.
- Review the plan yearly.
Find your real number
$500,000 can fund a secure 30-year retirement or a stressful 12-year one — and the difference is your spending, your Social Security, and a bit of market luck you can plan around. Rather than guess, see exactly how long your $500,000 will last free, with inflation, Social Security, and market volatility built in. Have more saved? Compare with how long $1 million lasts, or zoom out to how long your savings will last in retirement.
Frequently asked questions
Can you retire on $500,000?
Yes, many people do — especially alongside Social Security. At a 4% withdrawal that’s $20,000 a year from savings; combined with average benefits, that can support a modest-to-comfortable lifestyle depending on where you live and how you spend.
How long will $500,000 last at $30,000 a year?
Roughly 20 years at a 5% average return before Social Security. A poor sequence of early returns could shorten it, while Social Security could extend it well beyond 30 years.
How much monthly income does $500,000 generate?
At a 4% withdrawal, about $20,000 a year, or roughly $1,650 a month from the portfolio, before taxes and before adding Social Security.
Is $500,000 enough to retire at 62?
It can be, but retiring at 62 means a longer horizon and reduced Social Security if you claim early — both make it tighter. Testing your specific plan, including claiming age, is the only reliable way to know.
