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, but keeping it “safe” in cash will make you actively lose against inflation. Variables like healthcare costs, housing decisions and market performance also play a role in determining the longevity your savings.
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.
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 lose money, right? Wrong. Keeping your money in cash is the only investment that will actively lose you money 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% 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.

About This Calculator
To estimate how much you may need to save for retirement, we begin by calculating how much you're expected to spend over the course of your retirement. This includes estimating the income you'll need based on your lifestyle preferences, then factoring in how many years you may spend in retirement. We assume a lifespan of 95 by default, though you can adjust it after your calculation is complete.
Once we have a clearer view of your total retirement needs, we use our models to evaluate your existing and future resources. This includes estimating retirement income from Social Security and the impact of current retirement plans, pensions and other accounts. For additional inputs and a comprehensive retirement plan, please see our full Retirement Calculator.
Assumptions
Lifespan: We assume you will live to 95. We stop the analysis there, regardless of your spouse's age.
Retirement accounts: We automatically distribute your future savings optimally among different retirement accounts. We assume that the IRS contribution limits for your retirement accounts increase with inflation.
Social Security: We estimate your Social Security income using your stated annual income and assuming you have worked and paid Social Security taxes for 35 years prior to retirement. Our estimate is sensitive to penalties for early retirement and credits for delaying claiming Social Security benefits.
Return on savings: We assume the percentage return on your savings differs by whether you're pre- or post-retirement and by account type, with a distinction between investment accounts and savings accounts. This assumption does not account for market volatility or investment losses and assumes positive growth over time. All investing involves risk, including the possible loss of principal.

Bottom Line

How long $1,500,000 will last in retirement ultimately depends on your spending, withdrawal rate, investment strategy and longevity. By carefully estimating your monthly income needs and accounting for reliable income sources like Social Security, you can determine how much your portfolio must provide each year. From there, factors such as market performance, inflation and healthcare costs will influence sustainability.
