Is the 4% Rule Still Safe? A 2026 Reality Check

The 4% rule was built on 1990s assumptions. Here is how inflation, sequence risk, and today's yields change the conversation for retirees.

Retirement planning notes and a calculator with a coffee cup on a warm wood desk

The '4% rule' says a retiree can withdraw 4% of their portfolio in year one, adjust for inflation each year after, and have a high probability of not running out over 30 years. It was a useful starting point in 1994. It should not be the plan.

Why it feels shakier now

  • The original study assumed 50/50 U.S. stocks and intermediate Treasuries — a different world than today's globally diversified portfolios.
  • Sustained inflation above 3% strains any fixed-percentage rule.
  • Sequence-of-returns risk in the first 5-10 years matters more than the average return.

What we prefer instead

Rather than a single rigid number, most plans we build use a 'guardrails' approach: a target withdrawal, with rules for trimming or increasing spending based on portfolio performance. Paired with a bucket for near-term income, it tends to hold up better than a rule written before smartphones existed.

Frequently asked

Questions Scottsdale retirees ask us

What is a safe withdrawal rate in retirement today?
Recent research generally lands between 3.3% and 4.2% as an initial withdrawal rate for a 30-year retirement, depending on allocation and starting valuations. The right rate for your household depends on your income mix, flexibility, and legacy goals.
What are guardrails in a retirement withdrawal plan?
Guardrails set upper and lower thresholds for your portfolio value. If the portfolio grows past the upper rail, spending can rise; if it falls past the lower rail, spending is trimmed. It replaces a rigid percentage with a rules-based response to real market conditions.
How does sequence-of-returns risk affect withdrawals?
A large loss in the first few years of retirement — while you are withdrawing — permanently reduces the base your future compounding works on. That is why protection planning usually matters most in years 1-5.
