How Long Will $1.5 Million Last in Retirement?

James and Karen are 64 and 63 respectively. They've saved diligently — their combined retirement accounts total $1.5 million. They're two years from their target retirement date, and they want an honest answer to a simple question: Is it enough?

The honest answer: probably yes, with normal spending and Social Security. Definitely yes if they're flexible. Possibly not if healthcare costs spike or markets perform poorly early.

Let's look at the scenarios.

The Starting Point: The 4% Rule

The most cited benchmark for sustainable withdrawals is the "4% rule" — draw 4% of your initial portfolio in year one, then adjust for inflation annually. Based on historical data, this has historically sustained a portfolio for 30 years across most market conditions.

For $1.5 million:

• 4% withdrawal rate = $60,000/year
• 3% withdrawal rate = $45,000/year (more conservative)
• 5% withdrawal rate = $75,000/year (higher risk of depletion)

$60,000/year from the portfolio. That's before Social Security.

Adding Social Security

For most retirees, Social Security is the largest single income source. James and Karen are average earners who worked full careers:

• James's SS benefit (claiming at 67, his FRA): ~$28,000/year
• Karen's SS benefit (claiming at 66): ~$22,000/year
• Combined: $50,000/year

Total retirement income: $60,000 (portfolio) + $50,000 (SS) = $110,000/year

At $110,000/year, James and Karen can live comfortably in most U.S. markets. In high-cost areas like San Francisco or New York, it's tight. In mid-size cities or lower-cost states, it's sufficient to comfortable.

How Long Does the Portfolio Last?

The answer depends on returns, inflation, and spending.

Scenario modeling ($60,000/year withdrawals, $1.5M starting):

Most financial plans use 5–6% nominal return assumptions for a balanced portfolio. At those levels, $1.5 million with $60,000 withdrawals should last well beyond a 30-year retirement horizon.

The Spending Question

$1.5 million at 4% generates $60,000. But what does $60,000 actually buy?

Sample annual retirement budget:

This is a comfortable, not lavish, retirement budget. No mortgage, reasonable travel, decent healthcare coverage.

For James and Karen, with $110,000 in total income and $61,200 in spending, they have $48,800 in annual surplus. That buffer absorbs healthcare spikes, home repairs, grandchild expenses, or the desire for a special trip.

Risk Factors That Could Change the Outcome

Sequence of returns: A market crash early in retirement is the most significant near-term risk. Maintaining 1–2 years of cash reserves, keeping fixed income allocation appropriate, and having spending flexibility are the primary defenses.

Healthcare costs: Long-term care is the wild card. A multi-year nursing home need ($120,000–$130,000/year in many markets) can deplete a portfolio rapidly. Having a long-term care plan — insurance, hybrid policy, or self-insuring via a separate allocation — is important.

Inflation surprises: The 2022–2023 inflation surge reminded everyone that 2% isn't guaranteed. If inflation runs 4–5% for several years, portfolio withdrawals need to increase while real returns may lag.

Social Security changes: Current Social Security projections show the trust fund faces potential benefit reductions without legislative changes (projected around 2033 at current trajectory). Most analysts expect Congress to act before that point, but the uncertainty is real. Planning conservatively (modeling SS at 80% of current projections) is prudent.

Strategies to Make $1.5 Million Last

Delay Social Security. Every year you delay past FRA (up to 70) increases your benefit by 8%. A strategy where one or both spouses delay to 70 significantly strengthens the guaranteed income floor.

Maintain spending flexibility. Research shows that retirees who can reduce spending by 10–15% in down-market years have dramatically better portfolio survival rates. Having "discretionary" spending you can dial back creates a buffer.

Consider a hybrid income strategy. Dedicating a portion of the portfolio (say, $200,000–$300,000) to a deferred income annuity that starts paying at 80 can provide longevity insurance at a modest cost — while leaving the rest of the portfolio fully invested for growth.

Manage taxes. Roth conversions in early retirement, strategic withdrawal sequencing, and tax-efficient investing can meaningfully extend how long the portfolio lasts.

The Answer

Is $1.5 million enough? For James and Karen, yes — if they maintain reasonable spending and have solid Social Security income. With $110,000 in total income and modest spending, their portfolio is likely to last their lifetime and leave something for their children.

For someone with higher spending expectations, minimal Social Security, or significant healthcare risks, $1.5 million requires more careful planning.

The question isn't just whether the number is enough. It's whether the plan around the number is solid.

Work with a retirement advisor to model your specific scenario — spending, Social Security timing, healthcare costs — and build a plan that gives you confidence, not just a number.
