Planning for retirement can be intricate, which is why reducing it to a few basic guidelines feels reassuring. A commonly cited retirement “rule” is the “80% rule” (the exact percentage may vary slightly depending on the source): It claims that you’ll require 80% of your pre-retirement earnings to sustain your current standard of living.
This “rule” causes anxiety for many as they assess their IRAs and 401(k) plans using another popular guideline: The 4% safe withdrawal rule, which advises spending 4% of your savings in the first year of retirement and adjusting for inflation in later years. The goal is to ensure your funds last 30-50 years, preventing you from outliving your savings—though it’s often oversimplified to just withdrawing 4% of your retirement nest egg annually.
This is where the stress kicks in: If you have $200,000 in an IRA, 4% amounts to only $8,000. If you’re making $50,000 annually and believe you’ll need $40,000 to retire comfortably, panic might set in. But don’t worry, because the 80% rule is, frankly, nonsense.
What the 80% rule assumes
First and foremost, the 80% rule relies heavily on numerous assumptions, many of which no longer hold true for a significant number of people. This “rule” has been in circulation for decades and often presumes that you incur substantial commuting and work-related expenses (such as professional attire) and that many of us are tied to high-cost-of-living (HCOL) areas due to our jobs. However, in today’s world, where remote work and business casual attire are becoming increasingly common, these assumptions may not apply to you.
The rule also makes several assumptions about your financial situation. For instance, it typically assumes you’re saving at the average national rate (currently just over 3%)—but is that accurate for you? Are you saving significantly less—or perhaps more? Additionally, the rule presumes that your lifestyle will remain exactly the same in retirement—that you won’t relocate or alter your spending habits in any way. It also often assumes you’ll no longer have a mortgage, though in today’s world, this is becoming increasingly uncommon.
In reality, retirement spending is highly variable. While many individuals spend more in the early years of retirement as they travel and pursue new hobbies, they often reduce such expenditures as they age. At the same time, healthcare costs tend to rise with age, potentially increasing overall spending. The key takeaway isn’t whether your lifestyle will change—it’s that you can’t make blanket assumptions about how it will evolve.
The math doesn’t add up
A study by Aon Consulting revealed that the percentage of income required to sustain your lifestyle in retirement varies significantly, particularly benefiting those with mid-range incomes. For instance, someone earning $20,000 annually would need 94% of that income to maintain their lifestyle, whereas someone earning $90,000 would only need 78%. Those with even higher incomes might require an even larger percentage.
The reasons for this disparity become clear upon closer examination: Lower-income households save less because a larger portion of their earnings goes toward living expenses. They also pay fewer taxes, resulting in a smaller financial benefit when those taxes are no longer due. Most importantly, in the context of the 80% rule, lower-income individuals have limited flexibility to reduce their spending, making it difficult to adapt to a reduced income in retirement.
Focus on retirement spending
The real takeaway here is that the 80% rule isn’t about your income—it’s about your spending. In retirement, you generally have far more control over your spending than your income, which is often fixed or influenced by market conditions beyond your direct control. Retirees can adjust their spending in numerous ways, such as downsizing their home, relocating to a more affordable area, or cutting back on travel and luxury expenses.
It’s also worth considering other aspects of spending: Once retired, you’ll no longer contribute to retirement accounts, potentially reducing your savings-related expenses. Your tax situation will also change significantly, though there’s no guarantee your tax burden will decrease, as it depends on the sources of your retirement income.
However, the key takeaway is this: Numerous variables come into play. While the 80% rule is convenient for rough estimates, in reality, it serves more as a general guideline than a strict rule. Your retirement income requirements could be significantly lower or higher than 80%, making a detailed and personalized financial assessment essential. This doesn’t imply you shouldn’t save as much as possible for your retirement—it simply means relying on an arbitrary percentage isn’t the best way to gauge your preparedness.
