What's a safe withdrawal rate for early retirement?
TL;DR: The traditional 4% rule was modeled on a 30-year retirement horizon. For an early retirement that could last 50+ years, many planners suggest a more conservative rate (often cited in the 3-3.5% range) or a flexible withdrawal strategy that adjusts spending based on portfolio performance.
Why a longer horizon changes the number
A withdrawal rate that comfortably lasts 30 years can run out well before year 50 — more years means more exposure to a bad sequence of early returns, which is the single biggest risk to any fixed withdrawal strategy.
Strategies beyond a fixed percentage
- A flexible/dynamic withdrawal rate that reduces spending in down years
- A cash buffer covering 1-2 years of expenses, to avoid selling investments during a downturn
- A glide path that shifts allocation as you age through retirement

Frequently asked questions
Does the 4% rule still apply if I retire at 60 instead of 40?
It's much closer to the scenario it was originally modeled for (a ~30-year retirement), so it holds up better there than for a retirement starting decades earlier with a much longer expected horizon.
What is sequence-of-returns risk?
The risk that a market downturn early in retirement, combined with ongoing withdrawals, depletes a portfolio faster than the same average return spread evenly over time would — timing matters, not just the long-run average.
