The 4% Rule: Does It Still Work in 2026?

June 29, 2026

For decades, financial planners have pointed to the “4% rule” as a safe withdrawal rate in retirement. The premise is simple: If you withdraw 4% of your portfolio in year one and adjust for inflation each year, your nest egg should last 30 years. But is this classic rule still reliable for today’s retirees?

Where Did the 4% Rule Come From?

The 4% rule originated from research by financial planner William Bengen in 1994. He analyzed historical market data going back to 1926 and found that a 4% withdrawal rate would have survived every 30-year period—even through the Great Depression and the high inflation of the 1970s. Overnight, it became a foundational concept in retirement planning.

How Does the 4% Rule Work?

  • Initial Withdrawal: In your first retirement year, you withdraw 4% of your total retirement portfolio. For instance, if you start with $1 million, you take out $40,000.
  • Inflation Adjustments: Each year, you increase that $40,000 by the rate of inflation to preserve your purchasing power. So, if inflation is 3%, your second-year withdrawal would be $41,200, and so on.
  • Portfolio Longevity: The rule was designed to make your savings last for a 30-year retirement, even if you retire during challenging market conditions. It assumes a diversified portfolio—typically about 50-60% stocks and 40-50% bonds.

Why Does the Rule Still Appeal?

  • Historical Resilience: The 4% rule survived rigorous back-testing, including the worst economic periods in modern history like the Great Depression and the high inflation of the 1970s.
  • Simplicity: It gives retirees an easy way to estimate what a sustainable withdrawal might look like, providing clarity and a place to start their planning.
  • Predictability: Knowing you can replace your “paycheck” with a steady withdrawal brings peace of mind and helps prevent overspending in early retirement.

Real-World Spending Is Flexible

It’s important to remember that the 4% rule is based on a scenario where retirees increase spending with inflation every year and never adjust—regardless of market conditions or changing needs. Reality is different:

  • Spending Patterns: Most retirees spend more in the early years (enjoying travel and active lifestyles), often less in later years.
  • Built-In Buffer: If you voluntarily reduce withdrawals during poor markets or shift your spending habits over time, your chances of making your money last improve significantly.
  • Behavioral Adjustments: In practice, the ability to adjust—spending less in down years, for example—means your actual withdrawal rate can sometimes be higher than 4% in good markets, or you can preserve capital during downturns.

What We Actually Use at FND Financial Group

At FND Financial Group, we don’t rely on a one-size-fits-all rule. Every retirement journey is unique. Here’s how we approach retirement income:

  • Personalized Planning: Each plan factors in your Social Security decisions, tax efficiency, spending patterns, investment mix, and legacy goals.
  • The Guardrails Approach: Instead of a fixed withdrawal, we use the guardrails strategy to set upper and lower limits. If your portfolio grows, you can spend more. If it declines, we recommend temporarily tightening spending—helping your money last even if markets are volatile.
  • Flexible Spending: Real-world spending isn’t static. We account for phases of retirement, major purchases, healthcare costs, and the reality that spending often decreases later in life.
  • Robust Testing: We run Monte Carlo simulations to test your withdrawal strategy under hundreds of market scenarios, providing a clear picture of your plan’s resilience.
  • Ongoing Advice: Your life and the market change—so should your plan. We monitor and adjust your strategy over time to keep you on track and confident.

No two retirements are exactly alike, and we believe your plan should reflect that.
