How Long Will $3 Million Last in Retirement?

How long $3 million lasts in retirement depends on your spending habits and investment returns. Spending is largely within your control, but healthcare and other unexpected expenses can arise. While past investment returns offer a guideline, future performance can vary. For most people, a $3 million nest egg is likely to support a comfortable retirement.

If you need help developing a plan for retirement, consider talking to a financial advisor.

Estimating How Long $3 Million Will Last

Spending levels, investment returns and life expectancy determine how long your retirement savings will last. So do health status, household size, tax situation, inflation, and your state’s cost of living. Together, these factors create a complex picture that varies widely from person to person. Here are three scenarios showing how different approaches to spending and investing affect your retirement outlook.

The Conservative Approach

A 65-year-old couple with $3 million might withdraw 3% of their portfolio, or $90,000, in their first year of retirement, then increase withdrawals for inflation each year. A 3% rate is lower than the typical 4% withdrawal rule (now 4.7%), adding a margin of safety. If they earn an average 6% pre-tax annual return, which is a conservative figure for a diversified portfolio, they further stretch out their savings.

A 3% withdrawal on $3 million generates $90,000 in their first year. After adjusting for inflation, this can support a comfortable retirement in most areas. With a 6% annual return (which is, of course, not guaranteed), their portfolio could generate $175,000 per year, assuming steady market performance. Conservative spending and stable investment returns may help retirement savings last as long as you need it.

The Middle-of-the-Road Approach

A second couple, also age 65, plans moderate spending and expects to withdraw 4% of their savings in the first year. They allocate more to equities, accepting higher volatility in exchange for potentially greater long-term returns. They project 8% annual investment gains.

This approach provides $120,000 to spend in year one, compared with $240,000 in projected investment income under these assumptions. In this simplified example, investment income would exceed the initial withdrawal, which could allow the portfolio to maintain or increase its value. Actual results would vary with market returns, inflation, taxes, fees and the timing of gains and losses, so the example should not be interpreted to mean the portfolio would last indefinitely.

The Aggressive Approach

A third couple, both age 65, plans to withdraw $360,000 per year from their $3 million portfolio, which is 12% of their starting balance. They’re assuming 10% annual returns, which would equal about $300,000 on the initial $3 million portfolio.

Here’s the problem: Their planned withdrawals exceed the assumed return on their starting balance. With $3 million invested at a constant 10% return and $360,000 withdrawn at the start of each year, the portfolio would last roughly 14.9 years under these assumptions.

Inflation could shorten that timeline further if the couple wants to maintain the same purchasing power. Assuming 3% annual inflation, a 10% nominal return works out to a real return of about 6.79%: [(1.10 ÷ 1.03) – 1] × 100. Using that inflation-adjusted return and treating the $360,000 withdrawal as a constant amount in real dollars, the portfolio would be exhausted in about 11.5 years.

That means the couple would need to reduce withdrawals, earn higher returns, supplement the portfolio with other income or assets, or use some combination of these approaches to make the money last longer. Neither a 10% annual return nor a specific portfolio lifespan is guaranteed, and actual results would depend on market performance, inflation, fees, taxes and the timing of withdrawals.

Extending the Life of Your Retirement Savings

There are a number of steps retirees can take to stretch their retirement savings. Here are four common ones to consider: 

• Spend less: Most people find spending easier to control than investment returns. Downsizing, relocating to a lower-cost area or traveling during off-peak seasons are common ways to trim retirement expenses. Tax planning deserves attention here too. Taxes often rank as a major expense, second only to healthcare, making strategic tax decisions a practical lever for reducing annual spending. Unexpected costs, such as medical bills, still disrupt even well-planned budgets and push spending above target. But controlling what you can manage (housing, travel, and tax liability) gives you room to absorb the surprises that come.
• Invest more aggressively: A more aggressive approach to investing can translate to higher earnings, though there are no guarantees. Retirees might opt to put a larger percentage of their portfolio into higher earning assets, especially stocks, instead of safer assets, such as certificates of deposit (CDs), which may not even keep up with inflation. While stock-heavy portfolios have outperformed bonds over long periods, higher returns are never guaranteed and come with more risk. Retirees also face sequence-of-returns risk, as market losses early in retirement can have a greater impact when combined with ongoing withdrawals.
• Introduce additional income streams: Other income sources can also stretch your retirement fund. Social Security benefits, pensions, annuities or income from part-time work can help you maintain your lifestyle and slow the drawdown of your savings.
• Consider living in a tax-friendly state: One of the most effective ways to stretch a $3 million nest egg is to have residency in the most tax-friendly states. For example, some states don’t tax any income, including wages, salaries, dividends and interest, while others offer more targeted tax breaks for retirees. These differences can add up, especially for retirees with large withdrawals or several income streams, such as deductions or exemptions on retirement income.

Healthcare and Longevity Risks

Two factors that can put pressure on a $3 million retirement fund are medical costs and longer-than-expected lifespans. 

Healthcare costs tend to rise faster than general inflation, and retirees often face higher expenses as they age. Estimates from Fidelity suggest that a couple retiring at age 65 in 2025 will spend approximately $345,000 (on average) on health care and medical expenses in retirement, not including the cost of long-term care. ¹ Services like assisted living or nursing home stays can add hundreds of thousands more, depending on the length of care required.

Longevity is another key consideration. While many retirees plan for around a 20- to 25-year retirement, it is increasingly common for one or both members of a couple to live into their 90s. That extends the period during which withdrawals, healthcare spending and lifestyle costs must be covered.

Planning ahead for these risks can make a difference. Some retirees dedicate part of their savings specifically to healthcare needs, purchase long-term care insurance or use annuity products that provide lifetime income. Addressing both medical costs and the possibility of a longer life helps reduce the chance of depleting savings prematurely, even with a substantial balance such as $3 million.

Tax Planning for Portfolio Withdrawals

Taxes can affect how long a $3 million portfolio lasts and how much income it provides. Traditional 401(k) and IRA distributions generally create taxable income, while qualified Roth distributions do not. Selling investments in a taxable brokerage account can create a capital gain when the sale price exceeds what you paid for the investment.

The accounts you use first can shape your tax bill over time. Taking money from a brokerage account may leave retirement accounts invested longer, while tapping a traditional IRA can use lower tax brackets before other income begins. Roth savings can provide another source of money without adding qualified distributions to taxable income. The right combination will depend on the accounts you own and your income in a given year.

Required minimum distributions (RMDs) become part of the equation later in retirement. The starting age is 73 for people born from 1951 through 1959 and 75 for those born in 1960 or later. Because RMD amounts are tied to tax-deferred account balances, a larger balance can lead to a larger required distribution.

A Roth conversion can move money out of a traditional retirement account before RMDs begin. You generally owe income tax on the taxable amount converted, but that money can then grow in the Roth without being included in future RMD calculations for the original account. Spreading conversions across several lower-income years may offer more control over the tax rate paid on those funds.

Brokerage accounts provide another way to manage taxable income. Long-term investment gains are subject to separate federal tax rates, including a 0% rate for taxpayers who meet the income requirements. Retirees may be able to sell appreciated investments during years when their income is lower and have some or all of those gains fall within the 0% range.

Tax planning does not end when retirement begins. Social Security, RMDs, investment sales and changes in account values can alter the tax picture from one year to the next. A tax professional or financial advisor can help determine which accounts to tap and when based on your income needs and portfolio.

There are a lot of costs to consider for your retirement. Take a few minutes to see if your savings is on track:

Bottom Line

Planning for retirement with a $3 million portfolio opens up a range of possibilities, from conservative strategies focused on stability to approaches that embrace more risk in pursuit of higher returns. How long these savings last often comes down to spending patterns, investment choices and where you live. By considering tax policies, managing expenses and factoring in additional income sources, retirees can shape a financial plan that fits both their needs and their vision for the future.
