The 4% rule still outshines the 8% approach

by / ⠀News / June 2, 2025

The traditional 4% withdrawal rule for retirement remains a safer bet than the proposed 8% rate. The 4% rule, established by Bill Bengen in the 1990s, suggests retirees can withdraw 4% of their portfolio annually, adjusted for inflation. This gives a high likelihood of funds lasting for 30 years.

Morningstar’s recent analysis projects a safe rate below 4% due to lower expected bond yields and stock returns. However, some argue for higher withdrawal rates, like 8%. The 4% rule assumes a balanced portfolio of 60% stocks and 40% bonds.

It can sustain withdrawals over three decades. Historical returns have averaged about 10.7% annually from 1926 to 2024. Withdrawing 4% yearly lets retirees preserve their principal and account for inflation.

This ensures funds last through financial crises like the 2008 downturn, which saw a 37% market drop. The conservative 4% approach protects against sequence-of-return risk, where early market declines could deplete portfolios quickly. For a $1 million nest egg, withdrawing 4% yields $40,000 annually, adjustable upward with inflation.

This offers stability for a 65-year-old planning for an age of 95. Advocates of an 8% withdrawal rate argue it’s feasible for retirees with robust portfolios, especially during strong markets. From 2010 to 2020, the S&P 500 averaged 13.6% annual returns.

This suggests an 8% withdrawal ($80,000 from $1 million) could potentially grow the principal. However, an 8% rate carries significant risks, primarily sequence-of-return risk.

If a retiree begins withdrawing 8% during a market downturn, their portfolio could shrink rapidly, making recovery difficult. A $1 million portfolio dropping to $500,000 in the first year, with $80,000 withdrawn, would struggle to rebound. It risks depletion within 15 years.

The 2000-2002 dot-com crash shows how high withdrawals left retirees vulnerable. Longer lifespans also mean more people are living to 100 or beyond. This amplifies the risk of outliving one’s funds if medical costs spike.

Even in strong markets, high withdrawals erode compounding potential, undermining long-term growth. Doubling the safe withdrawal rate to 8% is generally unadvisable. It assumes sustained market gains and overlooks significant risks.

The 4% rule remains a reliable benchmark, albeit requiring some flexibility. Dynamic withdrawal strategies, like adjusting rates between 3% and 5% depending on markets, offer a middle ground. The bucket approach, dividing assets into short-term cash, medium-term bonds, and long-term stocks, also helps guard against forced sales during downturns.

Consulting a financial advisor is crucial to tailor withdrawals to one’s risk tolerance, portfolio size, and lifespan expectations. With expert guidance, your retirement financial goals are within reach.
