The $900,000 Question: What Does a Comfortable Retirement Actually Cost?
For millions of Americans, retirement feels like a moving target. Just when you think you have a number in mind, a new study shifts the goalposts. The latest analysis from Investopedia puts the figure at roughly $898,000 for a single American retiring at age 65 — and while that may sound daunting, understanding how that number is calculated can help you build a realistic and actionable retirement plan.
This figure is not pulled from thin air. It is grounded in real spending data, average Social Security benefits, and one of the most widely used financial planning rules available. Here is everything you need to know about what drives that number, how location changes it dramatically, and what steps you can take to close the gap between where you are and where you need to be.
Breaking Down the $898,000 Retirement Benchmark
According to the 2024 Consumer Expenditure Survey from the U.S. Bureau of Labor Statistics, a single American aged 65 or older living alone spends approximately $59,600 per year. That covers housing, healthcare, food, transportation, and other everyday expenses — a realistic snapshot of what life costs in retirement.
The average retired worker receives roughly $23,700 per year from Social Security, which helps offset a significant portion of those expenses. However, that leaves an annual income gap of approximately $35,900 that must be covered by personal savings and investments.
To calculate how large a nest egg is needed to fund that gap sustainably, Investopedia applied the widely cited 4% annual withdrawal rule. Under this rule, you divide your annual income need by 0.04 to determine the total savings required. When you do the math on $35,900, the result is approximately $898,000 — the cornerstone figure of this analysis.
What Is the 4% Rule and Why Does It Matter?
The 4% rule is one of the most enduring guidelines in personal finance. Originally derived from research known as the Trinity Study, it suggests that retirees can withdraw 4% of their portfolio in the first year of retirement, then adjust that amount for inflation each year, and have a high statistical probability of not outliving their money over a 30-year retirement horizon.
While some financial planners debate whether the 4% rule remains appropriate in today's low-yield, high-inflation environment, it remains a practical and widely accepted starting point for retirement planning. It translates an abstract income need into a concrete savings target — which is exactly what most people need to begin taking action.
Location Matters More Than You Might Think
One of the most striking findings in the Investopedia analysis is just how dramatically your required retirement savings vary depending on where you live. The difference between the most affordable and most expensive states is staggering.
- North Dakota represents the most affordable retirement environment, with a required nest egg of approximately $644,000 — the lowest of any state in the analysis.
- New Jersey, Hawaii, California, and Washington, D.C. sit at the opposite end of the spectrum, requiring retirement savings of more than $1 million for a single retiree to live comfortably.
These differences are driven by regional variations in housing costs, healthcare expenses, state income taxes on retirement income, and overall cost of living. A retiree in rural North Dakota faces a fundamentally different financial reality than someone living in San Francisco or Honolulu. This makes geographic planning one of the most powerful levers available to Americans who have flexibility in where they choose to retire.
How Does This Compare to What Americans Think They Need?
Interestingly, the $898,000 figure from Investopedia is considerably lower than what Americans themselves believe they need. Northwestern Mutual's 2026 Planning and Progress Study found that Americans cite $1.5 million as the amount necessary for a comfortable retirement. That perception gap reveals two important things.
First, many Americans may be overestimating the target, which could lead to unnecessary anxiety or a feeling that retirement is simply unreachable. Second, the data-driven $898,000 benchmark, while more attainable, still represents a significant financial challenge for the majority of households — particularly those who started saving late or have faced economic hardships along the way.
The Social Security Safety Net: Helpful, But Not Enough
Social Security plays a meaningful role in the retirement income equation, but the numbers make clear that it cannot carry the full load. The average benefit of roughly $23,700 per year covers less than 40% of the estimated $59,600 annual spending figure for single retirees. That structural gap is precisely why consistent, long-term personal saving and investing remain non-negotiable for anyone hoping to maintain their standard of living in retirement.
It is also worth noting that Social Security benefits vary based on your earnings history and the age at which you claim. Delaying your claim beyond age 65 — up to age 70 — can meaningfully increase your monthly benefit, which in turn reduces the burden placed on your personal savings.
Practical Steps to Close the Retirement Savings Gap
Whether the $898,000 benchmark feels close or far away, the path forward involves the same fundamental strategies applied consistently over time.
- Start or increase contributions to tax-advantaged accounts such as a 401(k) or IRA. The 2024 contribution limits allow workers to save up to $23,000 in a 401(k), with an additional $7,500 catch-up contribution for those aged 50 and older.
- Leverage employer matching if available. An employer match is essentially free money that accelerates your savings trajectory without requiring additional income.
- Consider your retirement location strategically. Moving from a high-cost state to a lower-cost one could reduce your required nest egg by hundreds of thousands of dollars — a powerful variable that is often overlooked.
- Delay Social Security if possible. Each year you wait past full retirement age adds approximately 8% to your annual benefit, which can significantly reduce how much your savings must cover.
- Work with a certified financial planner to create a personalized retirement income strategy that accounts for your specific expenses, health status, and lifestyle goals.
The Bottom Line
The $898,000 retirement savings target is not just a headline statistic — it is a grounded, data-driven benchmark that reflects the real costs of retirement for a single American today. While it is lower than the $1.5 million figure that many Americans fear they need, it remains a substantial goal that demands disciplined saving, smart investing, and thoughtful planning around location and Social Security timing.
The earlier you understand what you are working toward and why, the better positioned you will be to actually get there. Retirement is achievable for most Americans — but it rarely happens by accident.
