How Long Will $1,500,000 Last in Retirement?

If you have $1.5 million in retirement savings, you’re doing nearly five times as well as the median family with just $334,000. But how long $1.5 million will last in retirement depends on a range of factors, including annual spending, investment returns, inflation and lifestyle choices. Risky investments can make it disappear quickly, while cash holdings lose value to inflation over time. Variables like healthcare costs, housing decisions and market performance also affect how long your savings will sustain you.

A financial advisor can help you create a financial plan to maximize your savings and extend how long your money will last in retirement.

Determining How Much You Have

You may think that you have $1.5 million for retirement, but a closer inspection of your assets and income streams may make you realize you have more. A thorough inventory can reveal both how long $1.5 million might last and what you can spend each year.

Retirement Assets 

In addition to your $1.5 million, you may have other assets that you can use to supplement your income or include in your estate. Other assets that should be considered in your calculation can include: 

• Real estate assets that you might use to generate rental income, sold at a later date or gifted to heirs, like vacation homes or investment properties. 
• Recreational equipment that can be sold or rented like boats, RVs, travel trailers and off-road vehicles.
• The equity you’ve built in your home if you’re considering downsizing or moving to a cheaper area to reduce expenses. 

Retirement Income

In addition to income from your retirement accounts, you likely have other sources of income that will reduce the amount you need to withdraw to sustain your lifestyle. Other types of income you may have in retirement include: 

• Social Security benefits
• Pension benefits
• Part-time income
• Consulting income
• Rental income 
• Dividend income
• Interest income
• Inheritances
• Profit from selling a business or property

Estimate your regular monthly income and subtract it from your expected monthly expenses. For irregular income or annual income like royalties or inheritances, you can choose to amortize it based on when you expect to receive it, or leave it out of your planning altogether for a more conservative estimate.

How to Calculate Your Monthly Income Needs

If you’re wondering how long $1.5 million will last in retirement, the first step isn’t picking a withdrawal rate, it’s understanding how much you’ll actually need each month. Your income target becomes the foundation for estimating sustainability. Without a clear spending number, it’s difficult to determine whether $1,500,000 will support 20, 30 or even 40 years of retirement.

Start by estimating your core monthly expenses. These typically include housing costs, utilities, groceries, insurance premiums, transportation and healthcare. Even if your mortgage is paid off, property taxes, maintenance and insurance remain ongoing costs that must be factored in.

Next, account for discretionary spending. Travel, dining out, hobbies, charitable giving and helping family members can significantly increase your monthly needs. Many retirees find that spending is higher in the early years of retirement when they are more active, then gradually declines later.

Healthcare deserves special attention. Even with Medicare, retirees are responsible for premiums, supplemental coverage and out-of-pocket costs. Long-term care expenses, while not guaranteed, can also have a substantial financial impact and should be considered in long-range planning.

Ultimately, calculating your monthly income needs transforms the question from “Is $1.5 million enough?” to “Is my spending aligned with my assets?” Working with a financial advisor can help you refine your estimates, model different scenarios and build a withdrawal strategy designed to make your savings last throughout retirement.

Investing for Retirement

It can be tempting to put all of your savings in cash when you’re nearing or in retirement. After all, cash doesn’t depreciate, right? Wrong. Keeping your money in cash means you lose purchasing power because of inflation. 

If you retire at 62, you can reasonably expect to live to 82 if you’re a man or almost to 85 if you’re a woman, according to data from the Social Security Administration. That means your $1.5 million portfolio needs to last at least 20 years, but it can also grow. Time is every investor’s friend. 

Here’s how fast you would run out of money with each portfolio type, assuming you have a $1.5 million portfolio and withdrew $60,000 annually, taking out 3.8% more every year for inflation, which is the historical average annual inflation rate since 1960. 

Cash Portfolio

Withdrawing $60,000 annually from a $1.5 million portfolio kept in cash would lead you to run out of money in about 18 years. While $1.5 million divided by $60,000 is 25 years, the inflation rate means that you would need to progressively withdraw more every year to have the same buying power and run out of money faster. 

Bond Portfolio

A $1.5 million portfolio consisting entirely of bonds meant to keep pace with inflation may last about 25 years. You’ll need to withdraw more over time to maintain purchasing power, but your portfolio may keep pace with inflation. 

Stock Portfolio 

The average annualized rate of return of the stock market, as measured by the S&P 500, has historically been around 10%. Using that rate of return and still withdrawing $60,000 per year, increasing your withdrawal rate by 3.8% for inflation annually, a $1.5 million portfolio could last indefinitely. 

But average annualized rates of return don’t tell the whole picture. Some years are down and some years are up. While the stock market as a whole does well over time, if you pick individual stocks you could lose it all. Diversifying in an index fund that allows you to own tiny slices of the whole stock market can help mitigate risk but doesn’t make stocks a safe bet. 

If you lose a significant portion of your portfolio, panic and sell your investments, you’ve locked in a loss. If the market drops as you retire and your withdrawals rise, your portfolio might not recover. Only you know your risk tolerance. Working with a financial advisor can help you determine the right way to invest your portfolio for long-term stability. 

Investment returns, inflation and withdrawal rates all play a major role in determining how long retirement savings may last. Use the calculator below to estimate retirement income projections.

How Inflation and Healthcare Costs Can Change Your Number

The portfolio projections earlier in this article use a 3.8% historical average inflation rate, but two other variables can significantly alter those outcomes in ways that are easy to underestimate at the start of retirement: sustained inflation above the historical average and healthcare costs that rise faster than general inflation.

The Compounding Effect of Inflation Over a Long Retirement

Inflation does not just reduce purchasing power in any single year. It compounds over time in a way that makes a 25 or 30 year retirement significantly more expensive than a shorter one. At 3.8% annual inflation, $60,000 in annual spending today would require roughly $90,000 in 13 years and over $130,000 in 25 years to maintain the same standard of living. A period of elevated inflation, such as the 7% to 9% range seen in 2022 and 2023, would accelerate that erosion considerably and could substantially shorten the sustainability of a portfolio that appeared adequate under historical assumptions.

The practical implication is that a $1.5 million portfolio that looks comfortable at the beginning of retirement may face meaningful pressure in the later years, particularly if the first decade of retirement coincides with above-average inflation and withdrawals that have already grown substantially from the starting amount.

Healthcare Costs as a Separate Inflation Problem

Healthcare costs have historically risen faster than general inflation, and they tend to become a larger share of total spending as retirement progresses. According to Fidelity’s 2024 estimate, a single 65-year-old may need approximately $165,000 to cover healthcare costs in retirement, and a couple may need around $330,000. These figures cover Medicare premiums, supplemental coverage, dental, vision and out-of-pocket expenses, but they do not include long-term care costs, which can add tens of thousands of dollars per year if a nursing home or in-home care becomes necessary.

For a retiree withdrawing $60,000 annually, healthcare alone could represent a substantial and growing portion of that budget. A couple spending $15,000 per year on healthcare at 65 might see that figure climb to $25,000 or more by their late 70s, even without a major health event, simply due to premium increases and greater utilization of medical services.

What This Could Mean for Your $1.5 Million

When healthcare cost inflation is layered on top of general inflation, the real withdrawal rate can drift higher than planned even without any change in lifestyle. A portfolio designed around a specific annual withdrawal may be effectively drawing more in real terms each year, which reduces the number of years the savings can sustain that level of spending.

Building a healthcare cost estimate that grows faster than the rest of the budget, and stress-testing the portfolio against inflation scenarios above the historical average, gives a more realistic picture of how long $1.5 million is likely to last than a single-rate projection alone. A financial advisor can model these variables together and help you identify whether your current savings and withdrawal plan has enough cushion to absorb both.

Bottom Line

How long $1.5 million lasts in retirement depends on where you hold it, not just how much you have. A portfolio held entirely in a traditional IRA or 401(k) faces different tax consequences than the same amount in a Roth. The account type you choose, along with the conversions you make before retirement, can substantially affect your spendable income over decades.

“Remember that asset location and asset allocation are critical considerations in any modeling scenario for retirement savings. A $1.5 million nest egg held entirely in a traditional IRA or 401(k) won’t go as far as the same amount in a Roth, even if both are invested in the same stock portfolio. Strategies like Roth conversions completed in the years leading up to retirement or in early retirement can help minimize taxes, thus maximizing net income, and stretch savings further,” said Tanza Loudenback, CFP®.
