Is the 4% rule actually causing people to work 5 to 10 years longer than they need to?

In this episode of The Planning for Retirement Podcast, Kevin Lao breaks down a series of real historical 40 year retirement backtests using withdrawal rates of 4%, 5%, 6%, and even 7%, and the results are shocking.

Using Portfolio Visualizer, Kevin tests how different withdrawal rates would have performed starting in 1986 through 2025, and then compares those results to what happens when you retire into a tougher market environment like the lost decade (starting in 2000).

This episode is all about the real retirement planning lesson most people miss:

👉 The market you retire into matters more than the rule you follow.

And having a flexible withdrawal strategy beats blindly following any one “safe withdrawal rate.”

In this episode, you’ll learn:

• Why the 4% rule was never meant to be personalized

• How a higher withdrawal rate can work in some retirement scenarios

• Why sequence of returns risk can destroy even a “safe” retirement plan

• How Social Security timing can reduce long-term portfolio risk

• Why spending often declines in retirement (go-go, slow-go, no-go years)

• How taxes and account types (taxable vs IRA vs Roth) impact retirement withdrawals

• Why guardrails and flexible income planning are the key to retiring confidently

If you're approaching retirement and trying to determine your safe withdrawal rate, this episode will help you understand what really matters, and why retirement planning isn’t about following one rule of thumb, it’s about building a plan that adapts.
