Kevin O'Leary's $500K Retirement Rule Has a Catch Most People Miss

Retirement savings targets have a way of creeping higher over time. Depending on who you ask, the number can be $1 million, $1.5 million, or even more. Kevin O'Leary has offered a much smaller target, arguing that some Americans can retire with about $500,000.

The number may sound appealing, but retirement income rarely comes from savings alone. Before deciding whether O'Leary's rule fits your retirement plan, it helps to understand the role Social Security plays in the overall calculation.

What O'Leary actually said

In a YouTube video, O'Leary said a retiree could live "relatively comfortably" with about $500,000 in savings and "do nothing else to make money," provided the money was invested wisely.

He pointed to returns of roughly 5% from lower-risk fixed-income investments and 8.5% to 9% from a portfolio that includes stocks, as long as investors are willing to tolerate market swings. He also cautioned against taking unnecessary risks with retirement savings, joking, "Do not invest in your brother's restaurant."

Why a higher return does not mean higher spending

One detail that is easy to miss in O'Leary's argument is that the return your portfolio earns is not the same as the amount you can safely spend each year.

For example, earning 8% on a $500,000 portfolio does not automatically mean you can withdraw $40,000 every year. Markets go through good years and bad years, and retirees also need their savings to keep pace with inflation.

That is why many financial planners use the 4% rule as a starting point. The guideline suggests withdrawing 4% of your portfolio in your first year of retirement, then increasing that amount over time to account for inflation.

On a $500,000 portfolio, 4% would be $20,000 in the first year. After that, the withdrawal amount would increase a little each year to help your income keep up with rising costs.

O'Leary's point depends on the portfolio producing income, but retirees still have to be careful about how much they pull out. A $500,000 account has to support spending in good markets and bad ones.

How Social Security makes the $500,000 number work

On its own, a $20,000 withdrawal is unlikely to cover all of a retiree's spending needs, which is where Social Security becomes so important to O'Leary's $500,000 rule.

In January 2026, the average retired worker benefit is estimated at about $2,071 a month, or roughly $24,852 a year. Add that to a $20,000 portfolio withdrawal, and the total comes to about $44,852 a year before taxes.

For someone with low housing costs and careful spending, that number may feel more workable than $500,000 in savings sounds at first. Social Security provides more than half of the income in this example, and it comes with annual cost-of-living adjustments (COLAs).

Here is the difference in simple terms:

• Social Security alone: about $24,852 a year
• Social Security plus $500,000 in savings: about $44,852 a year
• Social Security plus $1.5 million in savings: about $84,852 a year

The $500,000 number depends heavily on Social Security because the monthly benefit provides a steady income base that the portfolio alone may not offer.

Who O'Leary's rule actually works for

Whether $500,000 is enough often comes down to what your monthly bills look like once you stop working.

For someone with a paid-off home or low rent, the roughly $44,852 a year in the example above may be enough to cover everyday expenses comfortably. The same income may feel much tighter for a retiree who is still making mortgage payments or paying market-rate rent.

You also need to account for Medicare, since retirees are still responsible for premiums, deductibles, and other out-of-pocket costs. Over time, those expenses can take up more of your retirement budget than you might expect.

The example also assumes an average retired worker benefit of about $2,071 a month from Social Security. A lower benefit would reduce the total income available each year. The same can happen in a household where one spouse receives a much smaller benefit or where a spousal benefit is not available.

That is why the $500,000 figure will feel very different from one household to the next. For retirees with low housing costs, average or above-average Social Security benefits, and a careful spending plan, it may be enough. For others, a larger nest egg may still be needed.

Bottom line

Part of the appeal of O'Leary's $500,000 rule is that it offers a clear answer to a question many retirees struggle with. The challenge is that retirement rarely comes with one number that works for everyone.

Your spending needs, income sources, lifestyle goals, and health care expenses all help determine how much is enough. Looking at your expected income alongside your regular expenses can provide a much clearer picture of whether your savings and income support your retirement goals.
