Two Retirees. Same Returns. Completely Different Outcomes.
Why average returns may be one of the most misleading numbers in retirement planning.
Imagine two retired couples.
Same portfolio.
Same average return.
Same withdrawal amount.
One enjoys a comfortable retirement.
The other runs out of money.
How is that possible?
One of the most dangerous assumptions in investing is the belief that average returns determine retirement success. They do not.
In fact, two retirees can experience identical average returns over retirement and still end up with dramatically different outcomes. That reality surprises many investors because we are conditioned to focus on averages.
Average annual returns are useful for comparison purposes. They are easy to calculate and easy to communicate.
Unfortunately, retirement does not occur in averages. Retirement occurs in real time.
Imagine two retirees, Susan and Robert. Both retire with one million dollars. Both withdraw the same amount each year. Both earn the exact same average return over a twenty-year retirement. On paper, their results should be similar. In practice, they may be very different.
Suppose Susan experiences strong market gains during the first several years of retirement. Her portfolio grows even as she takes withdrawals. Later market declines occur after substantial growth has already accumulated.
Now consider Robert. His retirement begins with a severe market decline. He continues withdrawing funds to support his lifestyle while the portfolio is depressed. Later gains occur, but the damage has already been done.
Both investors may eventually achieve the same average return. Yet Robert’s portfolio could be significantly smaller—or even exhausted.
This phenomenon is called sequence-of-returns risk. It is one of the most important retirement concepts investors can understand.
“Retirement success depends less on average returns and more on the order in which those returns occur.”
Sequence risk occurs because withdrawals amplify the impact of early losses. Assets removed from a declining portfolio no longer participate in future recoveries. The mathematics are unforgiving.
This is why retirement planning requires more than projecting average returns. Investors must evaluate how portfolios behave under adverse conditions.
What happens if a bear market arrives during the first five years of retirement? What if inflation remains elevated? What if spending needs increase unexpectedly? What if a spouse requires expensive healthcare?
Retirement success depends on resilience, not merely return expectations.
This distinction becomes increasingly important as life expectancy rises. Many retirees may spend twenty-five or thirty years in retirement. That extended timeframe creates more opportunities for unexpected events.
Average returns also ignore investor behavior. Markets rarely move in straight lines. Fear, greed, uncertainty, and headlines influence decision-making. Investors who panic during downturns may experience outcomes that differ substantially from theoretical projections.
Behavior often matters as much as portfolio design.
Successful retirees frequently share several characteristics. They maintain flexibility. They understand spending priorities. They prepare for uncertainty. They avoid overreacting to market volatility. Most importantly, they recognize that retirement planning is about managing risks rather than chasing maximum returns.
This perspective represents a meaningful shift from the accumulation years. During working years, investors often focus on growth. During retirement, preservation and sustainability become equally important.
That does not mean abandoning growth entirely. Portfolios still need growth to combat inflation and support long retirements. However, growth becomes one component of a broader strategy rather than the sole objective.
Diversification, cash reserves, withdrawal planning, tax management, and contingency planning all contribute to successful retirement outcomes. Many investors discover that retirement planning is ultimately a risk-management exercise—not a performance competition.
Financial media frequently highlights annual returns because they make attractive headlines. Retirement planning requires deeper analysis.
Investors should ask different questions: How vulnerable is my plan to poor early returns? How much flexibility exists in my spending? What happens if inflation exceeds expectations? How long can my portfolio support withdrawals under adverse scenarios?
These questions move the discussion from performance toward preparedness. Preparedness is what matters.
Retirement planning isn’t about predicting markets. It’s about preparing for uncertainty. The future will contain surprises. A sound retirement plan acknowledges that reality rather than ignoring it.
Most retirement projections assume smooth, predictable returns. Real life doesn’t.
